• haproxy not passing X_FORWARD_FOR on HTTP POST

  - by Mark L

  Hello, I've setup HAProxy with the option forwardfor option so it'll pass on the user's IP to PHP via $_SERVER[ "HTTP_X_FORWARDED_FOR" ]. If the page request isn't a POST it's populated fine but if it is then it won't be populated. Any ideas where I've gone wrong? Thanks everyone!

• Three ways to upload/post/convert iMovie to YouTube [closed]

  - by alexyu2010

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

• mod_access for lighttpd causes a 403 error for all POST requests

  - by Sam

  I have found on my debian server that running the lighttpd module mod_access is causing the server to response with a 403 to all POST requests. It's very odd as I have two servers, one is running as I'd expect and the other keeps returning these 403's. They are running identical configs for lighttpd and php. My lighttpd.conf is: https://gist.github.com/4269500 There is also one other custom conf: https://gist.github.com/4269508 I've opened up the servers for requests until I get this fixed, the server that works is http://mercury.isitup.org/ and the one that fails is http://venus.isitup.org/. After working out that disabling mod_access resolves the problem I greped all my lighttpd configs for uses of it (docs). Disabling each line I found didn't help, leading me to think this is perhaps some default behaviour (or bug?)... Has anyone come across this before or know what configuration value I've got wrong? Versions Debian: Debian GNU/Linux 6.0.6 (squeeze) Lighttpd: lighttpd/1.4.28 (ssl) PHP: PHP 5.3.19-1~dotdeb.0 with Suhosin-Patch (cli)

• Bios wont post unless I restart power supply.

  - by remy

  I have an annoying problem with a computer. The BIOS wont post after it has been turned off and started again unless I turn the switch off/on on the power supply. The fans, cdrom hdd and everything starts running but the bios never beeps and the monitor stays black. I HAVE TRIED: reinstalling windows xp, flashed bios to latest, cmos clear, new power supply, other hdd, new memory sticks, graphics card. I also removed the motherboard from the computer case and laid it on a cardboard box and only connected the PSU, RAM and CPU. Other than this the computer works great but its annoying having to off/on the power supply switch before turning it on after its been off. My guess is that the motherboard is faulty but I would just like to hear what you guys think. Sorry for my english / Remy

• Winamp "Now Playing" POST to PHP script

  - by Brad

  I have tried/researched 8 or so different plugins for Winamp that allow this functionality, and none of them seem to work on Windows 7 x64! I need a plugin for Winamp that will send the current playing track information to a PHP script, via GET or POST. I have almost no requirements... it can be the name/artist, or the filename (preferred). No fancy functionality needed, just something basic! The four that I actually are: Now Playing XML HTML Server SongStat Currently Hearing Any suggestions? (Note to Moderators: No, I'm not looking for "shopping recommendations", I just need a plugin that works. There probably is only "one answer" to this question, and if there isn't, feel free to make it a CW.)

• Puppet:get real-time status of catalog evaluation and post to remote server

  - by txworking

  According to this article http://docs.puppetlabs.com/guides/puppet_internals.html There are four phases when puppet agent got a catalog from master. resource generation = relationships = evaluation = reporting Reporting As the transaction progresses, it collects logs and metrics on what it does. At the end of evaluation, it turns this information into a report, which it sends to the server (if requested). And at the end of evaluation puppet agent would generate a report and sent the report to the master. Is there a way to get real-time status of evaluation phase and post them to a remote logcollector? Glad for any suggestions.

• FTP Server with MySQL access, and POST notification

  - by TIW

  Im looking for an FTP server solution, that we can host either internally on a dedicated server, or on Rackspace Cloud/AWS, that provides a HTTP POST notification when a file is uploaded, and allows user accounts to be created either through an API or MySQL database. There are several offerings that provide email notification - but has anyone come across anything that matches the above requirements. BrickFTP being a IaaS system is an option, but we would prefer something hosted in house. I don't believe the standard FTP servers provided with Apache can do the above ... can they?

• How to disable multiple form submit (POST) in IIS

  - by user1209640

  We had a major SharePoint outage a few months back because a user wedged their keyboard in such a way as to cause the Enter button to be pressed indefinitely. The user was on a customized people search page and hundreds of POSTs by the same user were submitted asynchronously, which overloaded the server. Because I work in a large organization, I am looking for a more global way to prevent this from happening. Is there a way to prevent multiple web form submissions by a common user within a short period of time within IIS? I am aware we can write javascript to disable the button after it is clicked, but we are hoping to prevent this issue from occurring on other pages where a similar possibility may exist. Update: It appears looking at the source code, the javascript is performing a document.location = url, whenever keycode 13 (Enter) is pressed. Again, we can write JS to prevent this in this location, but we also want to be able to guard against this kind of issue more generally... preferably at the IIS level.

• Dropdownlist post in ASP.NET MVC3 and Entity Framework Model

  - by Josh Blade

  I have 3 tables: RateProfile RateProfileID ProfileName Rate RateID RateProfileID PanelID Other stuff to update Panel PanelID PanelName I have models for each of these. I have an edit page using the RateProfile model. I display the information for RateProfile and also all of the Rates associated with it. This works fine and I can update it fine. However, I also added a dropdown so that I can filter Rates by PanelID. I need it to post back on change so that it can display the filtered rates. I'm using @Html.DropDownList("PanelID", (SelectList)ViewData["PanelDropDown"], new { onchange = "$('#RateForm').submit()" }) for my dropdownlist. Whenever it posts back to my HttpPost Edit method though, it seems to be missing all information about the Rates navigation property. It's weird because I thought it would do exactly what the input/submit button that I have in the form does (which actually passes the entire model back to my HttpPost Edit action and does what I want it to do). The panelID is properly being passed to my HttpPost Edit method and on to the next view, but when I try to query the Model.Rates navigation property is null (only when the post comes from the dropdown. Everything works fine when the post comes from my submit input). Get Edit: public ActionResult Edit(int id, int panelID = 1) { RateProfile rateprofile = db.RateProfiles.Single(r => r.RateProfileID == id); var panels = db.Panels; ViewData["PanelDropDown"] = new SelectList(panels, "PanelID", "PanelName", panelID); ViewBag.PanelID = panelID; return View(rateprofile); } HttpPost Edit: [HttpPost] public ActionResult Edit(RateProfile rateprofile, int panelID) { var panels = db.Panels; ViewData["PanelDropDown"] = new SelectList(panels, "PanelID", "PanelName", panelID); ViewBag.PanelID = panelID; if (ModelState.IsValid) { db.Entry(rateprofile).State = EntityState.Modified; foreach (Rate dimerate in rateprofile.Rates) { db.Entry(dimerate).State = EntityState.Modified; } db.SaveChanges(); return View(rateprofile); } return View(rateprofile); } View: @model PDR.Models.RateProfile @using (Html.BeginForm(null,null,FormMethod.Post, new {id="RateForm"})) { <div> @Html.Label("Panel") @Html.DropDownList("PanelID", (SelectList)ViewData["PanelDropDown"], new { onchange = "$('#RateForm').submit()" }) </div> @{var rates= Model.Rates.Where(a => a.PanelID == ViewBag.PanelID).OrderBy(a => a.minCount).ToList();} @for (int i = 0; i < rates.Count; i++) { <tr> <td> @Html.HiddenFor(modelItem => rates[i].RateProfileID) @Html.HiddenFor(modelItem => rates[i].RateID) @Html.HiddenFor(modelItem => rates[i].PanelID) @Html.EditorFor(modelItem => rates[i].minCount) @Html.ValidationMessageFor(model => rates[i].minCount) </td> <td> @Html.EditorFor(modelItem => rates[i].maxCount) @Html.ValidationMessageFor(model => rates[i].maxCount) </td> <td> @Html.EditorFor(modelItem => rates[i].Amount) @Html.ValidationMessageFor(model => rates[i].Amount) </td> </tr> } <input type="submit" value="Save" /> } To summarize my problem, the below query in my view only works when the post comes from the submit button and not when it comes from my dropdownlist. @{var rates= Model.Rates.Where(a => a.PanelID == ViewBag.PanelID).OrderBy(a => a.minCount).ToList();}

• REST web service keeps first POST parametrs

  - by Diego

  I have a web service in REST, designed with Java and deployed on Tomcat. This is the web service structure: @Path("Personas") public class Personas { @Context private UriInfo context; /** * Creates a new instance of ServiceResource */ public Personas() { } @GET @Produces("text/html") public String consultarEdad (@QueryParam("nombre") String nombre) { ConectorCliente c = new ConectorCliente("root", "cafe.sql", "test"); int edad = c.consultarEdad(nombre); if (edad == Integer.MIN_VALUE) return "-1"; return String.valueOf(edad); } @POST @Produces("text/html") public String insertarPersona(@QueryParam("nombre") String msg, @QueryParam("edad") int edad) { ConectorCliente c = new ConectorCliente("usr", "passwd", "dbname"); c.agregar(msg, edad); return "listo"; } } Where ConectorCliente class is MySQL connector and querying class. So, I had tested this with the @GET actually doing POST work, any user inputed data and information from ma Java FX app and it went direct to webservice's database. However, I changed so the CREATE operation was performed through a webservice responding to an actual POST HTTP request. However, when I run the client and add some info, parameters go OK, but in next time I input different parameters it'll input the same. I run this several times and I can't get the reason of it. This is the clients code: public class WebServicePersonasConsumer { private WebTarget webTarget; private Client client; private static final String BASE_URI = "http://localhost:8080/GetSomeRest/serviciosweb/"; public WebServicePersonasConsumer() { client = javax.ws.rs.client.ClientBuilder.newClient(); webTarget = client.target(BASE_URI).path("Personas"); } public <T> T insertarPersona(Class<T> responseType, String nombre, String edad) throws ClientErrorException { String[] queryParamNames = new String[]{"nombre", "edad"}; String[] queryParamValues = new String[]{nombre, edad}; ; javax.ws.rs.core.Form form = getQueryOrFormParams(queryParamNames, queryParamValues); javax.ws.rs.core.MultivaluedMap<String, String> map = form.asMap(); for (java.util.Map.Entry<String, java.util.List<String>> entry : map.entrySet()) { java.util.List<String> list = entry.getValue(); String[] values = list.toArray(new String[list.size()]); webTarget = webTarget.queryParam(entry.getKey(), (Object[]) values); } return webTarget.request().post(null, responseType); } public <T> T consultarEdad(Class<T> responseType, String nombre) throws ClientErrorException { String[] queryParamNames = new String[]{"nombre"}; String[] queryParamValues = new String[]{nombre}; ; javax.ws.rs.core.Form form = getQueryOrFormParams(queryParamNames, queryParamValues); javax.ws.rs.core.MultivaluedMap<String, String> map = form.asMap(); for (java.util.Map.Entry<String, java.util.List<String>> entry : map.entrySet()) { java.util.List<String> list = entry.getValue(); String[] values = list.toArray(new String[list.size()]); webTarget = webTarget.queryParam(entry.getKey(), (Object[]) values); } return webTarget.request(javax.ws.rs.core.MediaType.TEXT_HTML).get(responseType); } private Form getQueryOrFormParams(String[] paramNames, String[] paramValues) { Form form = new javax.ws.rs.core.Form(); for (int i = 0; i < paramNames.length; i++) { if (paramValues[i] != null) { form = form.param(paramNames[i], paramValues[i]); } } return form; } public void close() { client.close(); } } And this this the code when I perform the operations in a Java FX app: String nombre = nombreTextField.getText(); String edad = edadTextField.getText(); String insertToDatabase = consumidor.insertarPersona(String.class, nombre, edad); So, as parameters are taken from TextFields, is quite odd why second, third, fourth and so on POSTS post the SAME.

• Calling WCF service with parameter using jQuery

  - by Remi Despres-Smyth

  I'm trying to call a WCF web service hosted by IIS using jQuery. I can call it fine without any parameters, and I can also call it fine with a GET request that includes my parameter, but as soon as I try to send in the request via POST, the call is failing. The web service is currently nothing but: [OperationContract, WebInvoke] public ValidationResultSummary TestValidateOn( object day) { return null; } I've set the parameter to object, to make sure the issue isn't something with type coercion. With a breakpoint in the web service, I know the call without parameters as well as the GET call with param succeeds; in the latter the expected value is sent up. Calling code looks like: $.ajax({ // type: "GET", // url: "../Shared/Services/DomainServices.svc/TestValidateOn?day='12/Jan/2010'", type: "POST", url: "../Shared/Services/DomainServices.svc/TestValidateOn", // data: "{ }", --This works if object type param, calls with null data: "{'day': " + selectedDate + "}", // This fails miserably // data: "{'day': '" + selectedDate + "'}", --This also fails miserably contentType: "application/json; charset=utf-8", dataType: "json", success: function(data) { displayResults(data.d); }, error: function(xmlHttpReq, status, errThrown) { displayError(xmlHttpReq, status, errThrown); } }); The POST call never reaches my breakpoint, and on the client, error 500 - "Internal Server Error" - is returned. Any help would be appreciated.

• Label in PyQt4 GUI not updating with every loop of FOR loop

  - by user297920

  I'm having a problem, where I wish to run several command line functions from a python program using a GUI. I don't know if my problem is specific to PyQt4 or if it has to do with my bad use of python code. What I wish to do is have a label on my GUI change its text value to inform the user which command is being executed. My problem however, arises when I run several commands using a for loop. I would like the label to update itself with every loop, however, the program is not updating the GUI label with every loop, instead, it only updates itself once the entire loop is completed, and displays only the last command that was executed. I am using PyQt4 for my GUI environment. And I have established that the text variable for the label is indeed being updated with every loop, but, it is not actually showing up visually in the GUI. Is there a way for me to force the label to update itself? I have tried the update() and repaint() methods within the loop, but they don't make any difference. I would really appreciate any help. Thank you. Ronny. Here is the code I am using: # -*- coding: utf-8 -*- import sys, os from PyQt4 import QtGui, QtCore Gui = QtGui Core = QtCore # ================================================== CREATE WINDOW OBJECT CLASS class Win(Gui.QWidget): def __init__(self, parent = None): Gui.QWidget.__init__(self, parent) # --------------------------------------------------- SETUP PLAY BUTTON self.but1 = Gui.QPushButton("Run Commands",self) self.but1.setGeometry(10,10, 200, 100) # -------------------------------------------------------- SETUP LABELS self.label1 = Gui.QLabel("No Commands running", self) self.label1.move(10, 120) # ------------------------------------------------------- SETUP ACTIONS self.connect(self.but1, Core.SIGNAL("clicked()"), runCommands) # ======================================================= RUN COMMAND FUNCTION def runCommands(): for i in commands: win.label1.setText(i) # Make label display the command being run print win.label1.text() # This shows that the value is actually # changing with every loop, but its just not # being reflected in the GUI label os.system(i) # ======================================================================== MAIN # ------------------------------------------------------ THE TERMINAL COMMANDS com1 = "espeak 'senntence 1'" com2 = "espeak 'senntence 2'" com3 = "espeak 'senntence 3'" com4 = "espeak 'senntence 4'" com5 = "espeak 'senntence 5'" commands = (com1, com2, com3, com4, com5) # --------------------------------------------------- SETUP THE GUI ENVIRONMENT app = Gui.QApplication(sys.argv) win = Win() win.show() sys.exit(app.exec_())

• Wpf progressbar not updating during method calculation

  - by djerry

  Hey guys, In my app, i have an import option, to read info from a .csv or .txt file and write it to a database. To test, i"m just using 200-300 lines of data. At the beginning of the method, i calculate number of objects/lines to be read. Every time an object is written to the database, i want to update my progressbar. This is how i do it : private void Update(string path) { double lines = 0; using (StreamReader reader = new StreamReader(path)) while ((reader.ReadLine()) != null) lines++; if (lines != 0) { double progress = 0; string lijn; double value = 0; List<User> users = new List<User>(); using (StreamReader reader = new StreamReader(path)) while ((line = reader.ReadLine()) != null) { progress++; value = (progress / lines) * 100.0; updateProgressBar(value); try { User user = ProcessLine(lijn); } catch (ArgumentOutOfRangeException) { continue; } catch (Exception) { continue; } } return; } else { //non relevant code } } To update my progressbar, i'm checking if i can change the ui of the progressbar like this : delegate void updateProgressbarCallback(double value); private void updateProgressBar(double value) { if (pgbImportExport.Dispatcher.CheckAccess() == false) { updateProgressbarCallback uCallBack = new updateProgressbarCallback(updateProgressBar); pgbImportExport.Dispatcher.Invoke(uCallBack, value); } else { Console.WriteLine(value); pgbImportExport.Value = value; } } When i!m looking at the output, the values are calculated correctly, but the progressbar is only showing changes after the method has been called completely, so when the job is done. That's too late to show feedback to the user. Can anyone help me solve this. EDIT : I'm also trying to show some text in labels to tell te user what is being done, and those aren't udpated till after the method is complete. Thanks in advance.

• No long-running conversations - IllegalArgumentException: Stack must not be null

  - by Markos Fragkakis

  Hi all, I have a very simple application with just 2 pages on WebLogic 10.3.2 (11g), Seam 2.2.0.GA. I have a command button in each, which makes a redirect-after-post to the other. This works well, as I see the URL of the current page I am seeing in the address bar. BUT, even though I have no long-running conversations defined, after a random number of clicks, and - I think - after a random number of seconds (~10s - 60s) I get the lovely exception at the end of this post. Now, if I have understood how temporary conversations work when redirecting this happens: When I first see my application, the url is http://localhost:7001/myapp When I click the button in pageA.xhtml, I end up in "pageB.xhtml?cid=26". This is normal because Seam extends the temporary conversation of the first request to last until the renderResponse phase of the redirect. So, it uses the cid (Conversation Id) of the extended temporary conversation to find any propagated parameters. When I click the button in pageB.xhtml, I end up in pageA.xhtml?cid=26 The same cid was given to the new extended temporary conversation. This is normal because the conversation ended at the end of the previous redirect-after-post, and not the number 26 is free to use as a cid. Is this all correct? If yes, why does this happen: If I re-type the applications home address (showing pageA) and re-click, I end up in pageB.xhtml?cid=29, which is a different number than 26. But 26 has ended after the previous RenderResponse phase, befire I re-types the url. Why is it not used instead of 29? So, to sup up, 2 questions: Why do I get the exception, even though I have not started any long-running conversations? What happens exactly with the cid? On what basis does it change? Cheers,

• Posting xml from classic asp to asp.net

  - by Chris Dunaway

  I apologize if this has been asked before. I searched and didn't find anything that matched my situation. Also bear in mind I am fairly new to asp/asp.net development. My current project is a relatively simple e-commerce site. The customer will connect to the site, select products, input shipping and billing information, payment information (credit card) and submit the order. The project is being split into two parts: The store front which includes displaying the items and taking the customer's shipping and billing information and the payment site which will collect the customers credit card, compute tax, and save the order into the company's system. The reason that the site was split up, was that our side (payment side) already has facilities for credit card handling and tax computation. There may also be some regulatory issues that the store front side does not want to deal with (which we already do). I'm working on the payment portion of the app and I am using asp.net. The store front side is being written in classic asp (not my decision). Each part will be hosted on different servers. The problem I am having is transferring the contents of the "shopping cart" to our app so that we can collect the cc info and submit the order. We had thought that the classic asp could somehow post an xml fragment which contains the billing/shipping info and the items selected. Our side would display a summary of the order, securely collect the credit card info, and submit the order to our system. But I have been unable to post or send the xml from a classic asp on one server, to our asp.net application on another. It all works just fine when I test on the same server. How can I post (or otherwise transfer) the shopping cart data from classic asp to asp.net across server boundaries and transfer control to the asp.net application? As I said, I am new to web development, so this is proving quite a challenge for me. Thanks

• updating changes from one database to another database in the same server

  - by Pavan Kumar

  I have a copy of client database say 'DBCopy' which already contains modified data. The copy of the client database (DBCopy) is attached to the SQL Server where the Central Database (DBCentral) exists. Then I want to update whatever changes already present in DBCopy to DBCentral. Both DBCopy and DBCentral have same schema. How can i do it programatically using C#.NET maybe with a button click. Can you give me an example code as how to do it?. I am using SQL Server 2005 Standard Edition and VS 2008 SP1. In the actual scenario there are about 7 client database all with same schema as the central database. I am bringing copy of each client database and attach it to Central Server where the central database resides and try to update changes present in each copy of the client database to central database one by one programatically using C# .NET . The clients and the central server are physically seperate machines present in different places. They are not interconnected. I need to only update and insert new data. I am not bothered about deletion of data. Thanks and regards Pavan

• Mysteriously empty $_POST array

  - by Lex

  Hi all! I have the following HTML/PHP page: <?php if(empty($_SERVER['CONTENT_TYPE'])) { $type = "application/x-www-form-urlencoded"; $_SERVER['CONTENT_TYPE'] = $type; } echo "<pre>"; var_dump($_POST); var_dump(file_get_contents("php://input")); echo "</pre>"; ?> <form method="post" action="test.php"> <input type="text" name="test[1]" /> <input type="text" name="test[2]" /> <input type="text" name="test[3]" /> <input type="submit" name="action" value="Go" /> </form> As you can see, the form will submit and the expected output is a POST array with one array in it containing the filled in values and one entry "action" with the value "Go" (the button). However, no matter what values I enter in the fields; the result is always: array(2) { ["test"]=> string(0) "" ["action"]=> string(2) "Go" } string(16) "test=&action=Go&" Somehow, the array named test is emptied, the "action" variable does make it through. I've used the Live HTTP Headers extension for Firefox to check whether the POST fields get submitted, and they do. The relevant information from Live HTTP Headers (with a, b and c filled in as values in the textboxes): Content-Type: application/x-www-form-urlencoded Content-Length: 51 test%5B1%5D=a&test%5B2%5D=b&test%5B3%5D=c&action=Go Does anybody have any idea as to why this is happening? I'm freaking out on this one, it has cost me so much time already...

• Submit WordPress form password programmatically

  - by songdogtech

  How can I let a user access a WordPress protected page with a URL that will submit the password in the form below? I want to be able to let a user get to a password protected WordPress page without needing to type the password, so when they go to the page, the password is submitted by a POST URL on page load. This not intended to be secure in any respect; I'll need to hardcode the password in the URL and the PHP. It's just for simplicity for the user, and once they're in, the cookie will let them in for 10 more days. I will select the particular user with separate PHP function that determines their IP or WordPress login status. I used Wireshark to find the POST string: post_password=mypassword&Submit=Submit but using this URL mydomain.com/wp-pass.php?post_password=mypassword&Submit=Submit gives me a blank page. This is the form: <form action="http://mydomain.com/wp-pass.php" method="post"> Password: <input name="post_password" type="password" size="20" /> <input type="submit" name="Submit" value="Submit" /></form> This is wp-pass.php: <?php require( dirname(__FILE__) . '/wp-load.php'); if ( get_magic_quotes_gpc() ) $_POST['post_password'] = stripslashes($_POST['post_password']); setcookie('wp-postpass_' . COOKIEHASH, $_POST['post_password'], time() + 864000, COOKIEPATH); wp_safe_redirect(wp_get_referer()); ?> What am I doing wrong? Or is there a better way to let a user into a password protected page automatically?

• jquery .submit live click runs more than once

  - by fxuser

  I use the following code to run my form ajax requests but when i use the live selector on a button i can see the ajax response fire 1 time, then if i re-try it 2 times, 3 times, 4 times and so on... I use .live because i also have a feature to add a post and that appears instantly so the user can remove it without refreshing the page... Then this leads to the above problem... using .click could solve this but it's not the ideal solution i'm looking for... jQuery.fn.postAjax = function(success_callback, show_confirm) { this.submit(function(e) { e.preventDefault(); if (show_confirm == true) { if (confirm('Are you sure you want to delete this item? You can\'t undo this.')) { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } } else { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } return false; }) return this; }; $(document).ready(function() { $(".delete_button").live('click', function() { $(this).parent().postAjax(function(data) { if (data.error == true) { } else { } }, true); }); });? EDIT: temporary solution is to change this.submit(function(e) { to this.unbind('submit').bind('submit',function(e) { the problem is how can i protect it for real because people who know how to use Firebug or the same tool on other browsers can easily alter my Javascript code and re-create the problem

• weird problem with load () or live () !!

  - by silversky

  I load a page with load () and then I create dinamically a tag. Then I use live() to bind a click event and fires a function. At the end a call unload (). The problem is that when I load the same page again ( without refresh ) when on click the function will be fired twice. If I exit again (again with unload ()) and load the page again on click will fire 3 times and so on .... A sample of my code is: $('#tab').click(function() { $('#formWrap').load('newPage.php'); }); $('div').after('<p class="ctr" ></p>'); $('p.ctr').live('click', function(e) { if($(e.target).is('[k=lf]')) { console.log ('one'); delete ($this); } else if .... }); function delete () { $.post( 'update.php', data); } I have other $.post inside on this page and also on the above live fnc and all work well. The above one also works but like I said on the second load will fire twice and the 3 times and so on ... The weird part for me is that if replece the console with console.log ('two'); save the page and load the page without refresh it will fire on a different rows - one two - if I unload the page replace the console with console.log ('three'); and load again will fire one two and three. I try to use: $.ajax({ url: 'updateDB.php', data: data, type: 'POST', cache:false }); $.ajaxSetup ({ cache: false }); header("Cache-Control: no-cache"); none of this it's working. And I have this problem only on this fnc. What do you think, it could be the reason, it remembers it remembers the previous action and it fires again?

• Submit WordPress form programmatically

  - by songdogtech

  How can I let a user access a WordPress protected page with a URL that will submit the password in the form below? I want to be able to let a user get to a password protected WordPress page without needing to type the password, so when they go to the page, the password is submitted by a POST URL on page load. This not intended to be secure in any respect; I'll need to hardcode the password in the URL and the PHP. It's just for simplicity for the user, and once they're in, the cookie will let them in for 10 more days. I will select the particular user with separate PHP function that determines their IP or WordPress login status. I used Wireshark to find the POST string: post_password=mypassword&Submit=Submit but using this URL mydomain.com/wp-pass.php?post_password=mypassword&Submit=Submit gives me a blank page. This is the form: <form action="http://mydomain.com/wp-pass.php" method="post"> Password: <input name="post_password" type="password" size="20" /> <input type="submit" name="Submit" value="Submit" /></form> This is wp-pass.php: <?php require( dirname(__FILE__) . '/wp-load.php'); if ( get_magic_quotes_gpc() ) $_POST['post_password'] = stripslashes($_POST['post_password']); setcookie('wp-postpass_' . COOKIEHASH, $_POST['post_password'], time() + 864000, COOKIEPATH); wp_safe_redirect(wp_get_referer()); ?> What am I doing wrong?

• Complex derived attributes in Django models

  - by rabidpebble

  What I want to do is implement submission scoring for a site with users voting on the content, much like in e.g. reddit (see the 'hot' function in http://code.reddit.com/browser/sql/functions.sql). My submission model currently keeps track of up and down vote totals. Currently, when a user votes I create and save a related Vote object and then use F() expressions to update the Submission object's voting totals. The problem is that I want to update the score for the submission at the same time, but F() expressions are limited to only simple operations (it's missing support for log(), date_part(), sign() etc.) From my limited experience with Django I can see 4 options here: extend F() somehow (haven't looked at the code yet) to support the missing SQL functions; this is my preferred option and seems to fit within the Django framework the best define a scoring function (much like reddit's 'hot' function) in my database, and have Django use the value of that function for the value of the score field; as far as I can tell, #2 is not possible wrap my two step voting process in a suitably isolated transaction so that I can calculate the voting totals in Python and then update the Submission's voting totals without fear that another vote against the submission could be added/changed in the meantime; I'm hesitant to take this route because it seems overly complex - what is a "suitably isolated transaction" in this case anyway? use raw SQL; I would prefer to avoid this entirely -- what's the point of an ORM if I have to revert to SQL for such a common use case as this! (Note that this coming from somebody who loves sprocs, but is using Django for ease of development.) Before I embark on this mission to extend F() (which I'm not sure is even possible), am I about to reinvent the wheel? Is there a more standard way to do this? It seems like such a common use case and yet in an hour of searching I have yet to find a common solution...

• basic SQL atomicity "UPDATE ... SET .. WHERE ..."

  - by elgcom

  I have a rather basic and general question about atomicity of "UPDATE ... SET .. WHERE ..." statement. having a table (without extra constraint), +----------+ | id | name| +----------+ | 1 | a | +----+-----+ now, I would execute following 4 statements "at the same time" (concurrently). UPDATE table SET name='b1' WHERE name='a' UPDATE table SET name='b2' WHERE name='a' UPDATE table SET name='b3' WHERE name='a' UPDATE table SET name='b4' WHERE name='a' is there only one UPDATE statement would be executed with table update? or, is it possible that more than one UPDATE statements can really update the table? should I need extra transaction or lock to let only one UPDATE write values into table? thanks

• Javascript + PHP $_POST array empty

  - by Peterim

  While trying to send a POST request via xmlhttp.open("POST", "url", true) (javascript) to the server I get an empty $_POST array. Firebug shows that the data is being sent. Here is the data string from Firebug: a=1&q=151a45a150.... But $_POST['q'] returns nothing. The interesting thing is that file_get_contents('php://input') does have my data (the string above), but PHP somehow doesn't recognize it. Tried both $_POST and $_REQUEST, nothing works. Headers being sent: POST /test.php HTTP/1.1 Host: website.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://website.com/ Content-Length: 156 Content-Type: text/plain; charset=UTF-8 Pragma: no-cache Cache-Control: no-cache Thank you for any suggestions.

• PHP question about global variables and form requests

  - by user220201

  Hi, This is probably a stupid question but will ask anyway sine I have no idea. I have written basic php code which serve forms. Say I have a login page and I serve it using the login.php page and it will be called in the login.html page like this - <form action="login.php" method="post"> By this it is also implied that every POST needs its own php file, doesn't it? This kind of feels weird. Is there a way to have a single file, say code.php, and just have each of the forms as functions instead? EDIT: Specifically, say I have 5 forms that are used one after the other in my application. Say after login the user does A, B, C and D tasks each of which are sent to the server as a POST request. So instead of having A.php, B.php, C.php and D.php I would like to have a single code.php and have A(), B(), C() and D() as functions. Is there a way to do this? Also on the same note, how do I deal with say a global array (e.g. an array of currently logged in users) across multiple forms? I want to do this without writing to a DB. I know its probably better to write to a DB and query but is it even possible to do it with a global array? The reason I was thinking about having all the form functions in one file is to use a global array. Thanks, - Pav
