  • mysql_query arguments in PHP

    - by Chris Wilson
    I'm currently building my first database in MySQL with an interface written in PHP and am using the 'learn-by-doing' approach. The figure below illustrates my database. Table names are at the top, and the attribute names are as they appear in the real database. I am attempting to query the values of each of these attributes using the code seen below the table. I think there is something wrong with my mysql_query() function since I am able to observe the expected behaviour when my form is successfully submitted, but no search results are returned. Can anyone see where I'm going wrong here? Update 1: I've updated the question with my enter script, minus the database login credentials. <html> <head> <title>Search</title> </head> <body> <h1>Search</h1> <!--Search form - get user input from this--> <form name = "search" action = "<?=$PHP_SELF?>" method = "get"> Search for <input type = "text" name = "find" /> in <select name = "field"> <option value = "Title">Title</option> <option value = "Description">Description</option> <option value = "City">Location</option> <option value = "Company_name">Employer</option> </select> <input type = "submit" name = "search" value = "Search" /> </form> <form name = "clearsearch" action = "Search.php"> <input type = "submit" value = "Reset search" /> </form> <?php if (isset($_GET["search"])) // Check if form has been submitted correctly { // Check for a search query if($_GET["find"] == "") { echo "<p>You did not enter a search query.

  • jQuery slideToggle - when div is toggled it pushes content out of viewable area (IE)

    - by Chris
    This is an annoying ocurrance in IE when I use the jQuery slideToggle effect. Without the div being open, page looks normal. The minute I toggle the div open, it extends past the current content, overtop of the footer, and out of the viewable browser area (Even after scrolling all the way down). This feature seems to work just fine in firefox. Do I need an additional hack or CSS to make it work in IE8?

  • Using a user-defined type as a primary key

    - by Chris Kaminski
    Suppose I have a system where I have metadata such as: table: ====== key name address ... Then suppose I have a user-defined type described as so: datasource datasource-key A) are there systems where it's possible to have keys based on user-defined types? B) if so, how do you decompose the keys into a form suitable for querying? C) is this a case where I'm just better off with a composite primary key?

  • Change URL Submitted to Depending on Form Selection

    - by Chris
    I have a form which I need to submit to one of three different URLs depending on a selection made in the form. I suspect the easiest solution is to use jQuery to insert the appropriate path before the rest of the form parameters as the selection is made, but not sure on what the code would be. Any pointers greratly appreciated! <form id="myForm" action='/booking/default-path' accept-charset='utf-8' method='get'> <select name="paramA" id="paramA"> <option id="optionA" value="A" selected="selected">Option A</option> <option id="optionB" value="B">Option B</option> </select> <select name="currency" id="currency"> <option id="GBP" value="GBP" selected="selected">British Pounds</option> <option id="EUR" value="EUR">Euros</option> <option id="USD" value="USD">US Dollars</option> </select> <input type="submit" value="submit" id="submit" name="submit" /> </form> Where the three different URLs would be: ../booking/default-path-gbp?...[params here]... ../booking/default-path-eur?...[params here]... ../booking/default-path-usd?...[params here]... I know it would be a lot easier to incorporate the parameter in the usual way and just use one submission URL root, but unfortunately I'm submitting to an eComms system out of my control and am stuck with having to find a solution to this. Should be easy I think, but not sure where to start, jQuery used elsewhere, so would prefer to use this framework in any solutions.

  • What tools do you use to share knowledge amongst developers in your company?

    - by Chris Ross
    I'm looking for some good tools that help to share tips, best practices, company standards, etc. amongs developers in my company. Two tools I'm currently considering are a wiki (screwturn wiki) or Sharepoint 2010. I'm wondering if there is something better suited to the task, or any input anyone has on this subject. I'd prefer something that's windows based (i.e. runs on IIS, can authenticate users against Active Directory etc) but I am open to anything.

  • Visual Studio internal project references not always working

    - by Chris
    I am using Visual Studio and a solution with 10 or so projects in (mostly VB, some C#) which have various dependencies set up. Usually when I compile the solution it works fine. Occasionally when I do it I get a build error saying that one of the projects referenced is the wrong version (I think always the same one, possibly may be two that can cause problems). In this case going to the solution explorer and right clicking on the mentioned project and saying "rebuild" followed by another full build makes it work fine. I assume there is something set up wrong somewhere but I didn't set up the solution myself initially and a quick look through doesn't show anything immediately wrong. It feels like there is some kind of race condition, that VS is internally setting the version number of the project it needs before that project has been rebuilt and thus gets it wrong or something like that but I'm sure VS should handle all this sort of thing properly. Can anybody please suggest places that I could check for whether this has been correctly set up... And I should finally note that since I don't have reliable repro of this I may not be able to respond to questions too quickly. For example the obvious one of "Could you give the exact error message" will have to wait since I didn't think to copy it this morning, it was only after I cleared it up with the above steps that I thought to post here. Similarly any solutions may take a while to confirm.

  • Folder Renaming After Tar Extraction

    - by Chris S
    I have an tarball, myarchive.tar.gz. When I uncompress it using "tar -zxvf myarchive.tar.gz", it creates a folder myarchive-x980-2303-ssioo. What's the easiest way to automatically rename the extracted folder to ensure it matches the name of the archive? I've checked tar's manpage, but it doesn't seem to have an option for this.

  • In jQuery, is there any way to only bind a click once?

    - by Chris Henry
    I have an ajax app that will run functions on every interaction. I'd like to be able to run my setup function each time so all my setup code for that function remains encapsulated. However, binding elements more than once means that the handler will run more than once, which is obviously undesirable. Is there an elegant way in jQuery to call bind on an element more than once without the handler being called more than once?

  • trouble setting up TreeViews in pygtk

    - by Chris H
    I've got some code in a class that extends gtk.TreeView, and this is the init method. I want to create a tree view that has 3 columns. A toggle button, a label, and a drop down box that the user can type stuff into. The code below works, except that the toggle button doesn't react to mouse clicks and the label and the ComboEntry aren't drawn. (So I guess you can say it doesn't work). I can add rows just fine however. #make storage enable/disable label user entry self.tv_store = gtk.TreeStore(gtk.ToggleButton, str, gtk.ComboBoxEntry) #make widget gtk.TreeView.__init__(self, self.tv_store) #make renderers self.buttonRenderer = gtk.CellRendererToggle() self.labelRenderer = gtk.CellRendererText() self.entryRenderer = gtk.CellRendererCombo() #make columns self.columnButton = gtk.TreeViewColumn('Enabled') self.columnButton.pack_start(self.buttonRenderer, False) self.columnLabel = gtk.TreeViewColumn('Label') self.columnLabel.pack_start(self.labelRenderer, False) self.columnEntry = gtk.TreeViewColumn('Data') self.columnEntry.pack_start(self.entryRenderer, True) self.append_column(self.columnButton) self.append_column(self.columnLabel) self.append_column(self.columnEntry) self.tmpButton = gtk.ToggleButton('example') self.tmpCombo = gtk.ComboBoxEntry(None) self.tv_store.insert(None, 0, [self.tmpButton, 'example label', self.tmpCombo]) thanks.

  • Javascript to add cdata section on the fly?

    - by Chris G.
    I'm having trouble with special characters that exist in an xml node attribute. To combat this, I'm trying to render the attributes as child nodes and, where necessary, using cdata sections to get around the special characters. The problem is, I can't seem to get the cdata section appended to the node correctly. I'm iterating over the source xml node's attributes and creating new nodes. If the attribute.name = "description" I want to put the attribute.text() in a cdata section and append the new node. That's where I jump the track. // newXMLData is the new xml document that I've created in memory for (var ctr =0;ctr< this.attributes.length;ctr++){ // iterate over the attributes if( this.attributes[ctr].name =="Description"){ // if the attribute name is "Description" add a CDATA section var thisNodeName = this.attributes[ctr].name; newXMLDataNode.append("<"+thisNodeName +"></"+ thisNodeName +">" ); var cdata = newXMLData.createCDATASection('test'); // here's where it breaks. } else { // It's not "Description" so just append the new node. newXMLDataNode.append("<"+ this.attributes[ctr].name +">" + $(this.attributes[ctr]).text() + "</"+ this.attributes[ctr].name +">" ); } } Any ideas? Is there another way to add a cdata section? Here's a sample snippet of the source... <row pSiteID="4" pSiteTile="Test Site Name " pSiteURL="http://www.cnn.com" ID="1" Description="<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div>" CreatedDate="2010-09-20 14:46:18" Comments="Comments example.&#10;" > here's what I'm trying to create... <Site> <PSITEID>4</PSITEID> <PSITETILE>Test Site Name</PSITETILE> <PSITEURL>http://www.cnn.com</PSITEURL> <ID>1</ID> <DESCRIPTION><![CDATA[<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div ]]></DESCRIPTION> <CREATEDDATE>2010-09-20 14:46:18</CREATEDDATE> <COMMENTS><![CDATA[ Comments example.&#10;]]></COMMENTS> </Site>

  • prevent conversion of <br/>

    - by Chris
    Hello, I fear this is a dumb question, but I can't seem to find the answer. Pretty sure what that makes me...... I have C# generated HTML (HtmlGenerator), to which I sometimes want to insert a line break at a certain part of a cell's innertext. Here is how that comes out: <TD >There are lots of extra &lt; br /&gt; words here </TD> This then displays the <br/> as a part of my cell text - not good. Am I missing an easy way to have the <br/> preserved and not converted to &lt, etc...? thanks

  • Preventing a child process (HandbrakeCLI) from causing the parent script to exit

    - by Chris
    I have a batch conversion script to turn .mkvs of various dimensions into ipod/iphone sized .mp4s, cropping/scaling to suit. Determining the original dimensions, required crop, output file is all working fine. However, on successful completion of the first conversion, HandbrakeCLI causes the parent script to exit. Why would this be? And how can I stop it? The code, as it currently stands: #!/bin/bash find . -name "*.mkv" | while read FILE do # What would the output file be? DST=../Touch/$(dirname "$FILE") MKV=$(basename "$FILE") MP4=${MKV%%.mkv}.mp4 # If it already exists, don't overwrite it if [ -e "$DST/$MP4" ] then echo "NOT overwriting $DST/$MP4" else # Stuff to determine dimensions/cropping removed for brevity HandbrakeCLI --preset "iPhone & iPod Touch" --vb 900 --crop $crop -i "$FILE" -o "$DST/$MP4" > /dev/null 2>&1 if [ $? != 0 ] then echo "$FILE had problems" >> errors.log fi fi done I have additionally tried it with a trap, but that didn't change the behaviour (although the last trap did fire) trap "echo Handbrake SIGINT-d" SIGINT trap "echo Handbrake SIGTERM-d" SIGTERM trap "echo Handbrake EXIT-d" EXIT trap "echo Handbrake 0-d" 0

  • C# Application process hangs after some time

    - by Chris
    Hi, I implemented a simple C# application which inserts about 350000 records into the database. This used to work well and the process took approximately 20 minutes. I created a progress bar which lets you know approximately the progress of the records insertion. When the progress bar reaches about 75% it stops progressing. I have to manually terminate the program as the process doesn't seem to complete. If I use less data (like 10000), the progress bar finishes and the process is completed. However when I try to insert all the records, this won't happen any more. Note that if I wait longer to terminate the program manually, more records would have been inserted. For example, if I terminate the program after 15 minutes, 200000 records are inserted, whereas if I terminate the program after 20 minutes, 250000 records are inserted. This program is using a single thread. In face I can't do anything else until the process is complete. Does this have anything to do with threading or processes? Any feedback will be greatly appreciated. Thanks.

  • How to deal with unknown entity references?

    - by Chris
    I'm parsing (a lot of) XML files that contain entity references which i dont know in advance (can't change that fact). For example: xml = "<tag>I'm content with &funny; &entity; &references;.</tag>" when i try to parse this using the following code: final DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); final DocumentBuilder db = dbf.newDocumentBuilder(); final InputSource is = new InputSource(new StringReader(xml)); final Document d = db.parse(is); i get the following exception: org.xml.sax.SAXParseException: The entity "funny" was referenced, but not declared. but, what i do want to achieve is, that the parser replaces every entity that is not declared (unknown to the parser) with an empty String ''. Or even better, is there a way to pass a map to the parser like: Map<String,String> entityMapping = ... entityMapping.put("funny","very"); entityMapping.put("entity","important"); entityMapping.put("references","stuff"); so that i could do the following: final DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); final DocumentBuilder db = dbf.newDocumentBuilder(); final InputSource is = new InputSource(new StringReader(xml)); db.setEntityResolver(entityMapping); final Document d = db.parse(is); if i would obtain the text from the document using this example code i should receive: I'm content with very important stuff. Any suggestions? Of course, i already would be happy to just replace the unknown entity's with empty strings. Thanks,

  • Is there a 'RowSpan = "All"' in WPF

    - by Chris Spicer
    Take for the following for example: <GridSplitter Grid.Row="0" Grid.Column="1" Background="Yellow" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto" Grid.RowSpan="3" ResizeDirection="Columns etc etc This will create a GridSplitter across the 3 rows that I have in my grid. However, it's conceivable that I might add another row to my grid at a later stage, and I don't really want to go back and have all of my rowspans. My first guess was Grid.RowSpan="*", but that doesn't compile. Does anyone know the answer to this off hand?

  • In Visual Studio 2010, how do you invoke the "View In Browser" feature on an MVC app?

    - by Chris
    In Visual Studio 2010, you can right-click an aspx page in a web forms app, or on the web forms app itself in the solution explorer, and you get "View in Browser" in your context menu. In ASP.NET MVC projects, this item doesn't seem to be available in the context menu. The only way I know to run the app is to set the MVC app as a startup project and hit CTRL+F5. But, if there are two MVC apps in the solution, this doesn't really work. How do you accomplish this for mvc apps?

  • shorten something in AS 2.0 using eval or set?

  • What alternatives are there to Google App Engine?

    - by Chris Marasti-Georg
    What alternatives are there to GAE, given that I already have a good bit of code working that I would like to keep. In other words, I'm digging python. However, my use case is more of a low number of requests, higher CPU usage type use case, and I'm worried that I may not be able to stay with App Engine forever. I have heard a lot of people talking about Amazon Web Services and other sorts of cloud providers, but I am having a hard time seeing where most of these other offerings provide the range of services (data querying, user authentication, automatic scaling) that App Engine provides. What are my options here?

  • Pulling $_GET data and creating multidimensional array using loop

    - by Chris J
    I'm creating a checkout for customers and the data about what's in their cart is being sent to a page (for just now) via $_GET. I want to extract that data and then populate a multidimensional array with it using a loop. Here's how I'm naming the data: $itemCount = $_GET['itemCount']; $i = 1; while ($i <= $itemCount) { ${'item_name_'.$i} = $_GET["item_name_{$i}"]; ${'item_quantity_'.$i} = $_GET["item_quantity_{$i}"]; ${'item_price_'.$i} = $_GET["item_price_{$i}"]; //echo "<br />Name: " .${'item_name_'.$i}. " - Quantity: " .${'item_quantity_'.$i}. " - Price: ".${'item_price_'.$i}; $i++; } From here I'd like to create a multidimensional array like such: Array ( [Item_1] => Array ( [item_name] => Shoe [item_quantity] => 2 [item_price] => 40.00 ) [Item_2] => Array ( [item_name] => Bag [item_quantity] => 1 [item_price] => 60.00 ) [Item_3] => Array ( [item_name] => Parrot [item_quantity] => 4 [item_price] => 90.00 ) . . . ) What I'd like to know is if there is a way I can create this array in the existing while loop? I'm aware of being able to add data to an array like $data = [] after delacring an empty array but the actual syntax eludes me. Maybe I'm completely off the right track and there is a better way of doing it? Thanks

  • Regularly update database without browser/user

    - by Chris M
    I currently have a MySQL database which I was hoping to use to store regularly updated data from a temperature sensor connected to the internet. I currently have a page that, when opened, will grab the current temperature and the current timestamp and add it as an entry to the database, but I was looking for a way to do that without me refreshing the page every 5 seconds. Detail: The data comes from an Arduino Ethernet, posted to an IP address. Currently, I'm using cURL to grab the data from the IP, add a timestamp and save it to the DB. Obviously only updates when the page is refreshed (it uses PHP). Here is a live feed of the data - http://wetdreams.org.uk/ChrisProject/UI/live_graph_two.html TL;DR - Basically I need a middle man to grab the data from the IP and post it to a MySQL Edit: Thanks for all the advice. There might be a little bit of confusion, I'm looking for a solution that (ideally) doesn't require a computer to be on at all (other than the Server containing Database). Since I'm looking to store data over long periods of time (weeks), I'd like to set it up and leave a script running on the server (or Arduino) that gets the temp and posts it to the Database. In my head I would like to have a page on the server that automatically (without any browser open, or any other prompting other than a timer) calls a PHP script. Hope that clears things up!

  • How to calculate median of a Map<Int,Int>?

    - by Chris
    For a map where the key represents a number of a sequence and the value the count how often this number appeared in the squence, how would an implementation of an algorithm in java look like to calculate the median? For example: 1,1,2,2,2,2,3,3,3,4,5,6,6,6,7,7 in a map: Map<Int,Int> map = ... map.put(1,2) map.put(2,4) map.put(3,3) map.put(4,1) map.put(5,1) map.put(6,3) map.put(7,2) double median = calculateMedian(map); print(median); would result in: > print(median); 3 > So what i am looking for is a java implementation of calculateMedian.

  • Reusing an anonymous parameter in a prepared statement

    - by Chris Lieb
    I am customizing the insert SQL generated by hibernate and have hit an issue. When Hibernate generates the query by itself, it inserts data into the first two columns of the table, but this causes a database error since all four columns of the table are non-nullable. For the insert to be performed properly, it must insert the same data into two columns of the new record. This means that I need Hibernate to bind the same data to two different parameters in the query (prepared statement) that I am writing. Is there some SQL syntax that allows me to refer to anonymous parameters bound to a prepared statement in an order different from which they are bound? Details REF_USER_PAGE_XREF ---------------------------------------- PK FK1 | NETWORK_ID | VARCHAR2(100) PK FK1 | PAGE_PATH | VARCHAR2(1000) | USER_LAST_UPDT | VARCHAR2(100) | TMSP_LAST_UPDT | DATE insert into REF_USER_ROLE_XREF( NETWORK_ID, PAGE_PATH, TMSP_LAST_UPDT, USER_LAST_UPDT) values ( ?, /* want to insert the same data here */ ?, ?, /* and here */ (select to_char(sysdate, 'DD-MON-YY') from dual) I want to insert the same data into the first and third anonymous parameters.
