  • 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...

  • java.io.FileNotFoundException (Permission denied) When trying to write to the Android sdcard

    - by joefischer1
    I am trying to select an image file from the photo gallery and write to the sdcard. Below is the code that results in an exception. It appears to throw this exception when trying to create the FileOutputStream. I have the following line added to the manifest file nested inside the application element. I can't find a solution to the problem: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> public boolean saveSelectedImage( Uri selectedImage, int imageGroup, int imageNumber ) { boolean exception = false; InputStream input = null; OutputStream output = null; if( externalStorageIsWritable() ) { try { ContentResolver content = ctx.getContentResolver(); input = content.openInputStream( selectedImage ); if(input != null) Log.v( CLASS_NAME, "Input Stream Opened successfully"); File outFile = null; File root = Environment.getExternalStorageDirectory( ); if(root == null) Log.v(CLASS_NAME, "FAILED TO RETRIEVE DIRECTORY"); else Log.v(CLASS_NAME, "ROOT DIRECTORY is:"+root.toString()); output = new FileOutputStream( root+"/Image"+ imageGroup + "_" + imageNumber + ".png" ); if(output != null) Log.e( CLASS_NAME, "Output Stream Opened successfully"); // output = new FileOutputStream // ("/sdcard/Image"+imageGroup+"_"+imageNumber+".png"); byte[] buffer = new byte[1000]; int bytesRead = 0; while ( ( bytesRead = input.read( buffer, 0, buffer.length ) ) >= 0 ) { output.write( buffer, 0, buffer.length ); } } catch ( Exception e ) { Log.e( CLASS_NAME, "Exception occurred while moving image: "); e.printStackTrace(); exception = true; } finally { // if(input != null)input.close(); // if(output != null)output.close(); // if (exception ) return false; } return true; } else return false; }

  • Objects in JavaScript defined and undefined at the same time (in a FireFox extension)

    - by Alexey Romanov
    I am chasing down a bug in a FireFox extension. I've finally managed to see it for myself (I've only had reports before) and I can't understand how what I saw is possible. One error message from my extension in the Error Console is "gBrowser is not defined". This by itself would be surprising enough, since the overlay is over browser.xul and navigator.xul, and I expect gBrowser to be available from both. Even worse is the actual place where it happens: line 101 of nextplease.js. That is, inside the function isTopLevelDocument, which is only called from onContentLoaded, which is only called from onLoad here: gBrowser.addEventListener(this.loadType, function (event) { nextplease.loadListener.onContentLoaded(event); }, true); So gBrowser is defined in onLoad, but somehow undefined in isTopLevelDocument. When I tried to actually use the extension, I got another error: "nextplease is not defined". The interesting thing is that it happened on lines 853 and 857. That is, inside the functions nextplease.getNextLink = function () { nextplease.getLink(window.content, nextplease.NextPhrasesMap, nextplease.NextImagesMap, nextplease.isNextRegExp, nextplease.NEXT_SEARCH_TYPE); } nextplease.getPrevLink = function () { nextplease.getLink(window.content, nextplease.PrevPhrasesMap, nextplease.PrevImagesMap, nextplease.isPrevRegExp, nextplease.PREV_SEARCH_TYPE); } So nextplease is somehow defined enough to call these functions, but isn't defined inside them. Finally, executing typeof(nextplease) in Execute JS returns "object". Same for gBrowser. How can this happen? Any ideas?

  • Exporting to CSV from MySQL via PHP in FireFox

    - by typoknig
    Hi all, I am pulling some info from a database with the following code: <input type="button" value="Export to Excel" onClick="window.navigate('breakfast_service.php?action=export')"> Here is the code for that action. <?php if ($_GET['action'] == 'export') { // Get the registration data $user = 'root'; $pass = 'billiards'; $server = 'localhost'; $link = mysql_connect($server, $user, $pass); if (!$link) { die('Could not connect to database!' . mysql_error()); } mysql_select_db('breakfast', $link); $query = "SELECT * FROM registration"; $result = mysql_query($query); mysql_close($link); // format into CSV $contents = "id, school_id, first_name, last_name, email, attending, created_on\n"; $num = mysql_num_rows($result); for ($i = 0; $i < $num; $i++) { $row = mysql_fetch_array($result); $id = $row['id']; $school_id = $row['school_id']; $fname = $row['first_name']; $lname = $row['last_name']; $email = $row['email']; $attending = ($row['attending'] == 0) ?

Why?

  • AJAX Partial Rendering issues for the default page in IIS 7 when using custom http module

    - by WiseGuyEh
    The problem When I try to make a AJAX partial update request (using the UpdatePanel control) from the default page of an IIS7 web site, it fails- instead of returning the html to be updated, it returns the entire page, which then causes the MS AJAX Javascript to throw a parsing shit-fit. The suspected cause I have narrowed the cause down to two issues- making an AJAX request to the default page when I have a certain custom http module registered. A partial rendering request to http://localhost will fail, but a partial rendering request to http://localhost/default.aspx will work fine. Also, If i remove the following line in my custom HttpModule: _application.PreRequestHandlerExecute += OnPreRequestHandlerExecute; The AJAX partial render will work correctly. Wierd huh? Another wierd thing... If I look at trace.axd, I can see that when a partial rendering request fails, two POST requests are logged for the one partial rendering request- one where the default.aspx page executes successfully (trace information such as page_load is logged) but no content is produced and a second that doesn't seem to actually execute (no trace information is logged) but produces content (HTTP_CONTENT_LENGTH is greater than 0). Please help! If anyone with a good knowledge of HTTP modules or the MS AJAX Http module could explain why this is occuring I would be very grateful. As it is, the obvious work arround is to just redirect to default.aspx if the request url is "/" but I would really like to understand why this is occurring.

  • In WPF, accessing containers within ListBox

    - by Jim
    I'm creating a DerivedListBox : ListBox and a DerivedHeaderedContentControl : HeaderedContentControl, which will serve as a container for each item in the ListBox. In order to calculate the size available for the expanded content of the DerivedHeaderedContentControls, I am storing each container object in a list within the DerivedListBox. This way I can calculate the height of the headers of each DerivedHeaderedContentControl and subtract that from the total size available to the DerivedListBox. This would be the size available for the expanded content of a DerivedHeaderedContentControl. public class DerivedHeaderedContentControl : HeaderedContentControl { // Do some binding to DerivedListBox to calculate height. } public class DerivedListBox : ListBox { private List<DerivedHeaderedContentControl> containers; protected override DependencyObject GetContainerForItemOverride() { DerivedHeaderedContentControl val = new DerivedHeaderedContentControl(); this.containers.Add(val); return val; } // Do some binding to calculate height available for an expanded // container by iterating over containers. } The problem comes in when the DerivedListBox's ItemsSource is cleared (or an item in the items source is removed). How can I determine when the ItemsSource is cleared so that I can clear the containers list?

  • Looking for how-to use UIGraphicsSetPDFContextURLForRect on iOS or Cocoa

    - by user1676332
    I'm playing to manipulate PDF on iOS (display but also and mostly generation). I wish to embed rectangular areas which act as "external" links (URLs like http://host.tld/path/file). Do you know where I can find an example(s) of how to use the UIGraphicsSetPDFContextURLForRect function? I find absolutly nothing on Internet. If I understand well, the only requirement is that the current graphic context should be PDF "type" and I think I respect this since, upstream, I call UIGraphicsPushContext why my PDF context as parameter (this was anyway required for methods like drawAtPoint: that I use also with success). I do not think it is important but just in case I specify that this DOES NOT take place in the drawRect: of a View subclass. You're quite right to say me unequivocally that I have "all wrong". The graphical environment is so sophisticated and rich in iOS that I assume to have not assimilated more than 1 or 2% for now. Thank you in advance.

  • Django Threaded Commenting System

    - by Yasin Ozel
    (and sorry for my english) I am learning Python and Django. Now, my challange is developing threaded generic comment system. There is two models, Post and Comment. -Post can be commented. -Comment can be commented. (endless/threaded) -Should not be a n+1 query problem in system. (No matter how many comments, should not increase the number of queries) My current models are like this: class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() child = generic.GenericRelation( 'Comment', content_type_field='parent_content_type', object_id_field='parent_object_id' ) class Comment(models.Model): content = models.TextField() child = generic.GenericRelation( 'self', content_type_field='parent_content_type', object_id_field='parent_object_id' ) parent_content_type = models.ForeignKey(ContentType) parent_object_id = models.PositiveIntegerField() parent = generic.GenericForeignKey( "parent_content_type", "parent_object_id") Are my models right? And how can i get all comment (with hierarchy) of post, without n+1 query problem? Note: I know mttp and other modules but I want to learn this system. Edit: I run "Post.objects.all().prefetch_related("child").get(pk=1)" command and this gave me post and its child comment. But when I wanna get child command of child command a new query is running. I can change command to ...prefetch_related("child__child__child...")... then still a new query running for every depth of child-parent relationship. Is there anyone who has idea about resolve this problem?

  • forcing a child component to resize itself larger than its container

    - by Josh
    I am creating a component that displays a variable amount of "gauges" (square tiles of content if you will), that is laid out like so: <HDividedBox id="container"> <VBox id="myComponent"> <HBox id="header"> ...header content... </HBox> <Tile id="body"> ...gauges are added to the body... </Tile> </Vbox> </HDividedBox> The body Tile has a horizontal direction. When I drag the HDividedBox to make myComponent smaller, the body component will get smaller as well, and eventually if there are too many gauges to fit horizontally, they will be bumped to the next row, and thus the smaller I make myComponent, the number of vertically stacked gauges grows. This is all well and good. The problem is, no matter what combination of settings I use, I absolutely cannot get the body (a Tile) to size itself beyond the size of myComponent, which would ideally cause myComponent to scroll vertically. Even setting the maxHeight of the body to some huge value, it will never size itself larger than it's container. Any ideas on how to accomplish this? Thanks

  • Automatically grow document view of NSScrollView using auto layout?

    - by Monolo
    Is there a simple way to get an NSScrollView to adapt to its document view changing size when using autolayout (the Lion feature)? I have tried to call both setNeedsUpdateConstraints: and setNeedsLayout: on the document view, the clip view and the scroll view, without any results. fittingSize of the document view reports the correct size. An NSPopover in conjunction with an NSViewController handles this nicely, with the popover growing and shrinking as needed, and I was hoping to get a similar simple and robust behaviour with the scroll view. I have checked the documentation for scroll views, but they don't seem to be updated to use autolayout. Edited to clarify: The problem I experience is that the document view, which holds subviews, is not re-sized when the subviews change their size, even if they call invalidateIntrinsicContentSize. The contents of the document view are hence clipped to the original size of the document view as they grow. The document view is created in a nib and set as the scroll view's document view in an awakeFromBib method. What I hoped to obtain was that the document view frame would automatically be adjusted to when its fittingSize changes, and the scrollbars updated accordingly. NSPopover does something similar - provided that the subviews of the content controller's view have the constraints set right and various content hugging values are high enough (higher than the hidden popover window's hight constraint priority, for one).

  • Ajax -- re-load div on success.

    - by RPM
    I am trying to accomplish a "re-load." More specifically, I need to be able to refresh a portion of my page as a result of another successful ajax call. Moreover, I load my portion of the page via ajax which obtains it's content from an ajax post. The result is my content being displayed inside my portion precisely. I need this portion of the page refreshed after a successful ajax post. Here is some of the code: /* Ajax-- this part is loaded automatically, and I need it reloaded upon success of another ajax post. This data comes from the outcome of my other ajax function. */ $('#newCo').load('click', function() { $.ajax({ url: 'index.php?dkd432k=uBus/310/Indeed', dataType: 'json', success: function(json) { if (json['newCompare']) { $('#newCo .newResults').html(json['newCompare']); } } }); }); The next portion of code is responsible for posting the data of which I obtain in this above ajax function. function ZgHiapud (ofWhich) { $.ajax({ url: 'index.php?dkd432k=uBus/310/update', type: 'post', data: 'product_id=' + product_id, dataType: 'json', success: function(json) { $('.success, .warning, .attention, .information').remove(); if (json['success']) { $('.attention').fadeIn('slow'); $('#compare_total').html(json['total']); $('html, body').animate({ scrollTop: 0 }, 'slow'); } } }); } In the end, I need to obtain the data that I send to the server immediately upon success of the second ajax call. This data that is sent via the second ajax call needs to fire the first ajax call upon success.

  • UIView: how to do non-destructive drawing?

    - by Caffeine Coma
    My original question: I'm creating a simple drawing application and need to be able to draw over existing, previously drawn content in my drawRect. What is the proper way to draw on top of existing content without entirely replacing it? Based on answers received here and elsewhere, here is the deal. You should be prepared to redraw the entire rectangle whenever drawRect is called. You cannot prevent the contents from being erased by doing the following: [self setClearsContextBeforeDrawing: NO]; This is merely a hint to the graphics engine that there is no point in having it pre-clear the view for you, since you will likely need to re-draw the whole area anyway. It may prevent your view from being automatically erased, but you cannot depend on it. To draw on top of your view without erasing, do your drawing to an off-screen bitmap context (which is never cleared by the system.) Then in your drawRect, copy from this off-screen buffer to the view. Example: - (id) initWithCoder: (NSCoder*) coder { if (self = [super initWithCoder: coder]) { self.backgroundColor = [UIColor clearColor]; CGSize size = self.frame.size; drawingContext = [self createDrawingBufferContext: size]; } return self; } - (CGContextRef) createOffscreenContext: (CGSize) size { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, size.width, size.height, 8, size.width*4, colorSpace, kCGImageAlphaPremultipliedLast); CGColorSpaceRelease(colorSpace); CGContextTranslateCTM(context, 0, size.height); CGContextScaleCTM(context, 1.0, -1.0); return context; } - (void)drawRect:(CGRect) rect { UIGraphicsPushContext(drawingContext); CGImageRef cgImage = CGBitmapContextCreateImage(drawingContext); UIImage *uiImage = [[UIImage alloc] initWithCGImage:cgImage]; UIGraphicsPopContext(); CGImageRelease(cgImage); [uiImage drawInRect: rect]; [uiImage release]; } TODO: can anyone optimize the drawRect so that only the (usually tiny) modified rectangle region is used for the copy?

  • 404 Error using Flash Builder 4 BlazeDS wizard

    - by codeflayer
    Hello again Stackoverflow! My issue this time around is trying to use the new DCD BlazeDS wizard in Flash Builder 4. If I set my project up as a combined Java/Flex app I am unable to connect to the RDS servlet using the wizard. I get a 404 error every time. I'm certain the service is set up correctly since my app can access the exposed java classes and BlazeMonster can see the exposed services. Is anyone else having this issue and if so has anyone found a work-around? I'd very much like to use the code generation features of the wizard for my project. Thanks as always, Codeflayer

  • How to run some code only once in view

    - by Freewind
    I have a partial view called '_comment.erb', and it may be called by parent many times(e.g. in a loop). The '_comment.erb' looks like: <script> function aaa() {} </script> <%= comment.content %> <%=link_to_function 'Do', 'aaa()' %> You can see if the '_comment.erb' be called many times, that the javascript function 'aaa' will be re-defined many times. I hope it can be define only once, but I don't want to move it to parent view. I hope there is a method, say 'run_once', and I can use it like this: <%= run_once do %> <script> function aaa() {} </script> <% end %> <%= comment.content %> <%=link_to_function 'Do', 'aaa()' %> No matter how many time I call the '_comment.erb', the code inside 'run_once' will be run only once. What shall I do?

  • AS3 Memory Conservation (Loaders/BitmapDatas/Bitmaps/Sprites)

    - by rinogo
    I'm working on reducing the memory requirements of my AS3 app. I understand that once there are no remaining references to an object, it is flagged as being a candidate for garbage collection. Is it even worth it to try to remove references to Loaders that are no longer actively in use? My first thought is that it is not worth it. Here's why: My Sprites need perpetual references to the Bitmaps they display (since the Sprites are always visible in my app). So, the Bitmaps cannot be garbage collected. The Bitmaps rely upon BitmapData objects for their data, so we can't get rid of them. (Up until this point it's all pretty straightforward). Here's where I'm unsure of what's going on: Does a BitmapData have a reference to the data loaded by the Loader? In other words, is BitmapData essentially just a wrapper that has a reference to loader.content, or is the data copied from loader.content to BitmapData? If a reference is maintained, then I don't get anything by garbage collecting my loaders... Thoughts?

  • IE6 PNG-transparency CSS hack not working

    - by John
    I looked around and decided to use a CSS approach rather than rely on JS... I figure the kind of corporate users stuck with IE6 might also have JS disabled by IT departments. So In my HTML I have: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <title>My Page</title> <link rel="stylesheet" type="text/css" href="default.css" /> <!--[if IE 6]><link rel="stylesheet" type="text/css" href="ie6.css"><![endif]--> </head> <body> <img src="media/logo.png"/> </body> Then my ie6.css consists simply of: img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...); } However none of this makes the slightest difference, no transparency. I commented out all the rest of the page so it is literally that one and still no luck. I removed the default.css stylesheet and still no difference.

  • Encoding MySQL text fields into UTF-8 text files - problems with special characters

    - by Matt Andrews
    I'm writing a php script to export MySQL database rows into a .txt file formatted for Adobe InDesign's internal markup. Exports work, but when I encounter special characters like é or umlauts, I get weird symbols (eg Chloë Hanslip instead of Chloë Hanslip). Rather than run a search and replace for every possible weird character, I need a better method. I've checked that when the text hits the database, it's saved properly - in the database I see the special characters. My export code basically runs some regular expressions to put in the InDesign code tags, and I'm left with the weird symbols. If I just output the text to the browser (rather than prompt for a text file download), it displays properly. When I save the file I use this code: header("Content-disposition: attachment; filename=test.txt"); header("Content-Type: text/plain; charset=utf-8"); I've tried various combinations of utf8_encode() and iconv() to no avail. Can anybody point me in the right direction here?

  • Best way for launching html/jsp to communicate with GWT module

    - by h2g2java
    I asked this at the GWT forum but I'm impatient for the answer and I seem to get rather good responses here. A html or jsp file is used to launch the xxx.nocache.js, which then decides which browser "permutation" to use. <head> <meta http-equiv="content-type" content="text/html;charset=UTF-8"> <title>xxx</title> <script type="text/javascript" language="javascript" src="xxx.nocache.js"></script> </head> In my case, I am using a jsp. When the JSP is executed, it discovers some conditions. I wish to pass these conditions as values to the GWT module being launched. The "elegant" GWT way to pass these values would be to persist them as request/memcache attributes and then have the GWT module perform RPC to retrieve those values. For example, the JSP discovers that the current user is Whoopy. Shouldn't I simply have the JSP generate javascript to store user = "Whoopy" as a top or namedframe level javascript variable and use JSNI within the module to retrieve the value for user? I have not tried it yet, but I would like to know how anyone might have done it without having to use RPC.

  • Problem consuming Exchange Web Service 2010 with jax-ws metro

    - by Johan Karlberg
    I am trying to consume the Exchange 2010 Web Service interface using JAX-WS. I'm using JAX-WS 2.2 RI (Metro 2.0). 2.1 exhibited the same problem. I am running into trouble with Exchange, which returns "HTTP/1.1 415 Cannot process the message because the content type 'text/xml;charset=utf-8' was not the expected type 'text/xml; charset=utf-8'." as a reponse (2.1 quoted the charset value, otherwise same response). Apparently I need to dictate the exact Content-type header for Exchange to be happy. Is there a way for me to do this without forcing me to manually rebuild the dependency? I currently rely on published maven artifacts, and would like to continue doing this if at all possible. The consuming process is a regular J2SE app, with no containers in sight. I have control of the application and can add pretty much anything required to the applications scope, but can not add out-of-process items like proxy servers. The client classes were generated from local WSDL, but the charset specification is derived from constants declared in the jaxws RI implementation, not the generated code. The resulting HTTP transport is thus handled by the standard http/https client from Sun JRE5 or JRE6.

  • Django + jQuery: Sometimes AJAX, but always DRY?

    - by Justin Myles Holmes
    Let's say I have an app (in Django) for which I want to sometimes (but not always) load content via ajax. An easy example is logging in. When the user logs in, I don't want to refresh the page, just change things around. Yet, if they are already logged in, and then arrive at (or refresh) the same page, I want it to show the same content. So, in the first case, obviously I do some sort of ajax login and load changes to the page accordingly. Easy enough. But what about in the second case? Do I go back through and add {% if user.authenticated %} all over the place? This seems cold, dark, and WET. On the other hand, I can just wrap all the ajaxy stuff in a javascript function, called loggedIn(), and run that if the user is authenticated. But then I'm faced with two http requests instead of one. Also undesirable. So what's the standard solution here?

  • jQuery date picker not persistant after AJAX

    - by ILMV
    So I'm using the jQuery date picker, and it works well. I am using AJAX to go and get some content, obviously when this new content is applied the bind is lost, I learnt about this last week and discovered about the .live() method. But how do I apply that to my date picker? Because this isn't an event therefore .live() won't be able to help... right? This is the code I'm using to bind the date picker to my input: $(".datefield").datepicker({showAnim:'fadeIn',dateFormat:'dd/mm/yy',changeMonth:true,changeYear:true}); I do not want to call this metho everytime my AJAX fires, as I want to keep that as generic as possible. Cheers :-) EDIT As @nick requested, below is my wrapper function got the ajax() method: var ajax_count = 0; function getElementContents(options) { if(options.type===null) { options.type="GET"; } if(options.data===null) { options.data={}; } if(options.url===null) { options.url='/'; } if(options.cache===null) { options.cace=false; } if(options.highlight===null || options.highlight===true) { options.highlight=true; } else { options.highlight=false; } $.ajax({ type: options.type, url: options.url, data: options.data, beforeSend: function() { /* if this is the first ajax call, block the screen */ if(++ajax_count==1) { $.blockUI({message:'Loading data, please wait'}); } }, success: function(responseText) { /* we want to perform different methods of assignment depending on the element type */ if($(options.target).is("input")) { $(options.target).val(responseText); } else { $(options.target).html(responseText); } /* fire change, fire highlight effect... only id highlight==true */ if(options.highlight===true) { $(options.target).trigger("change").effect("highlight",{},2000); } }, complete: function () { /* if all ajax requests have completed, unblock screen */ if(--ajax_count===0) { $.unblockUI(); } }, cache: options.cache, dataType: "html" }); } What about this solution, I have a rules.js which include all my initial bindings with the elements, if I were to put these in a function, then call that function on the success callback of the ajax method, that way I wouldn't be repeating code... Hmmm, thoughts please :D
