  • How do I use theme preprocessor functions for my own templates?

    - by Jergason
    I have several .tpl.php files for nodes, CCK fields, and Views theming. These template files have a lot of logic in them to move things around, strip links, create new links, etc. I understand that this is bad development and not "The Drupal Way". If I understand correctly, "The Drupal Way" is to use preprocessor functions in your template.php file to manipulate variables and add new variables. A few questions about that: Is there a naming convention for creating a preprocessor function for a specific theme? For example, if I have a CCK field template called content-field-field_transmission_make_model.tpl, how would I name the preprocessor function? Can I use template preprocessor functions for node templates, CCK field templates, and Views templates? Do they have different methods of modifying template variables or adding new ones?

  • Respect regular onsubmit handlers from jQuery.submit

    - by orip
    I want a jQuery form submit handler to respect any previous submit handlers, including ones added with onsubmit. I'm trying to detect the previous handler's return value but can't seem to do it: <form><input type="submit" /></form> <script type="text/javascript"> $('form')[0].onsubmit = function() { return false; }; // called first $('form').submit(function(e) { console.log(e.result); // undefined console.log(e.isDefaultPrevented()); // false console.log(e.isPropagationStopped()); // false console.log(e.isImmediatePropagationStopped()); // false }); </script> Is there a way to do this?

  • C# Threads.Abort()

    - by Betamoo
    If a thread is running a function func1 that calls another function func2 inside it... Then I called thread.Abort() Will this stop func1 only OR func1 and func2 and all the functions func1 has called?? Thanks Edit: Here are more detail: func1 is called in a new thread, it continuously calls func2 on regular basis... func2 begin doing some work only if some array is not null.. it finishes it and return When supervisor wants to save data, it aborts Thread of func1- and then makes array null, saves data, then fill in the array with new one.. and starts Thread with func1 again.. Sometimes exception is raised because array is null in func2.. so func1 abort did not affect func2

  • post data to a thickbox using ajax

    - by sqlchild
    I need to post data to a thickbox using ajax and open it immediately and display the posted data. The user would click on a link/button and the data i.e. value of the selected checkboxes would be posted to "my_thickbox.php" and the thickbox (url : my_thickbox.php) would open with checkbox values displayed. <div id="showthickbox" ><a href="my_thickbox.php" class="thickbox"></div> $('#showthickbox').click(function() { var data = $('input:checkbox:checked').map(function() { return this.value; }).get(); $.ajax({ type: 'POST', url: 'my_thickbox.php', data: data, success: success, dataType: dataType }); });

  • Using IoC and Dependency Injection, how do I wrap an existing implementation with a new layer of imp

    - by Dividnedium
    I'm trying to figure out how this would be done in practice, so as not to violate the Open Closed principle. Say I have a class called HttpFileDownloader that has one function that takes a url and downloads a file returning the html as a string. This class implements an IFileDownloader interface which just has the one function. So all over my code I have references to the IFileDownloader interface and I have my IoC container returning an instance of HttpFileDownloader whenever an IFileDownloader is Resolved. Then after some use, it becomes clear that occasionally the server is too busy at the time and an exception is thrown. I decide that to get around this, I'm going to auto-retry 3 times if I get an exception, and wait 5 seconds in between each retry. So I create HttpFileDownloaderRetrier which has one function that uses HttpFileDownloader in a for loop with max 3 loops, and a 5 second wait between each loop. So that I can test the "retry" and "wait" abilities of the HttpFileDownloadRetrier I have the HttpFileDownloader dependency injected by having the HttpFileDownloaderRetrier constructor take an IFileDownloader. So now I want all Resolving of IFileDownloader to return the HttpFileDownloaderRetrier. But if I do that, then HttpFileDownloadRetrier's IFileDownloader dependency will get an instance of itself and not of HttpFileDownloader. So I can see that I could create a new interface for HttpFileDownloader called IFileDownloaderNoRetry, and change HttpFileDownloader to implement that. But that means I'm changing HttpFileDownloader, which violates Open Closed. Or I could implement a new interface for HttpFileDownloaderRetrier called IFileDownloaderRetrier, and then change all my other code to refer to that instead of IFileDownloader. But again, I'm now violating Open Closed in all my other code. So what am I missing here? How do I wrap an existing implementation (downloading) with a new layer of implementation (retrying and waiting) without changing existing code? Here's some code if it helps: public interface IFileDownloader { string Download(string url); } public class HttpFileDownloader : IFileDownloader { public string Download(string url) { //Cut for brevity - downloads file here returns as string return html; } } public class HttpFileDownloaderRetrier : IFileDownloader { IFileDownloader fileDownloader; public HttpFileDownloaderRetrier(IFileDownloader fileDownloader) { this.fileDownloader = fileDownloader; } public string Download(string url) { Exception lastException = null; //try 3 shots of pulling a bad URL. And wait 5 seconds after each failed attempt. for (int i = 0; i < 3; i++) { try { fileDownloader.Download(url); } catch (Exception ex) { lastException = ex; } Utilities.WaitForXSeconds(5); } throw lastException; } }

  • C++ adding friend to a template class in order to typecast

    - by user1835359
    I'm currently reading "Effective C++" and there is a chapter that contains code similiar to this: template <typename T> class Num { public: Num(int n) { ... } }; template <typename T> Num<T> operator*(const Num<T>& lhs, const Num<T>& rhs) { ... } Num<int> n = 5 * Num<int>(10); The book says that this won't work (and indeed it doesn't) because you can't expect the compiler to use implicit typecasting to specialize a template. As a soluting it is suggested to use the "friend" syntax to define the function inside the class. //It works template <typename T> class Num { public: Num(int n) { ... } friend Num operator*(const Num& lhs, const Num& rhs) { ... } }; Num<int> n = 5 * Num<int>(10); And the book suggests to use this friend-declaration thing whenever I need implicit conversion to a template class type. And it all seems to make sense. But why can't I get the same example working with a common function, not an operator? template <typename T> class Num { public: Num(int n) { ... } friend void doFoo(const Num& lhs) { ... } }; doFoo(5); This time the compiler complaints that he can't find any 'doFoo' at all. And if i declare the doFoo outside the class, i get the reasonable mismatched types error. Seems like the "friend ..." part is just being ignored. So is there a problem with my understanding? What is the difference between a function and an operator in this case?

  • Parsing secure entries XML file with jquery

    - by user573131
    Apologies if this is elementary. I'm primarily a front end designer/dev. I have webform through a form service called wufoo. Wufoo generates a lovely XML (or json) file that can be grabed and parsed. I'm trying to grab the entries xml feed that is associated with the form and parse it via jquery to show who has entered. Im using the following code (which works with a local xml file). http://bostonwebsitemakeover.com/2/test <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js"></script> <script> $(document).ready(function () { $.ajax({ type: "GET", url: "people.xml", dataType: "xml", success: xmlParser }); }); function xmlParser(xml) { $('#load').fadeOut(); $(xml).find("Entry").each(function () { $(".main").append('<div class="entry">' + $(this).find("Field1").text() + ' ' + $(this).find("Field2").text() + ' http://twitter.com/' + $(this).find("Field17").text() + '</div>'); $(".entry").fadeIn(1000); }); } </script> My XML file contains the following: <?xml version="1.0"?> <Entries> <Entry> <EntryId>1</EntryId> <Field1>Meaghan</Field1> <Field2>Severson</Field2> <Field17/> </Entry> <Entry> <EntryId>2</EntryId> <Field1>Michael</Field1> <Field2>Flint</Field2> <Field17>michaelflint</Field17> </Entry> <Entry> <EntryId>3</EntryId> <Field1>Niki</Field1> <Field2>Brown</Field2> <Field17>nikibrown</Field17> </Entry> <Entry> <EntryId>4</EntryId> <Field1>Niki</Field1> <Field2>Brown</Field2> <Field17>nikibrown</Field17> </Entry> </Entries> I'm wondering how I would do this with the xml file hosted on the wufoo (which is https) So I guess Im asking how do I authenticate the feed via jquery? Or do i need to do this via json? Could someone explain how?

  • Implement functionality in PHP?

    - by Rachel
    How can we Implement Bisect Python functionality in PHP Implement function bisect_left($arr, $item); as a pure-PHP routine to do a binary-bisection search for the position at which to insert $item into $list, maintaining the sort order therein. Assumptions: Assume that $arr is already sorted by whatever comparisons would be yielded by the stock PHP < operator, and that it's indexed on ints. The function should return an int, representing the index within the array at which $item would be inserted to maintain the order of the array. The returned index should be below any elements in $arr equal to $item, i.e., the insertion index should be "to the left" of anything equal to $item. Search routine should not be linear! That is, it should honor the name, and should attempt to find it by iteratively bisecting the list and comparing only around the midpoint.

  • how to perform click to the output of ActionLink by jQuery or javascript?

    - by user324003
    <%= Ajax.ActionLink("Edit", "Update", "Home", new { id = item.mID }, new AjaxOptions { OnBegin = "function(){ $('#edit" + item.mID + "').show();}", HttpMethod = "get", UpdateTargetId = "edit" + item.mID })%> The above code generates the html source code. when user click the link, it works well. But there're so many links there, I must click them one by one. Is there any method to click once, all of them excutes? I tried the method: $("a.buttonID").click() and modified the above code: <%= Ajax.ActionLink("Edit", "Update", "Home", new { id = item.mID }, new AjaxOptions { OnBegin = "function(){ $('#edit" + item.mID + "').show();}", HttpMethod = "get", UpdateTargetId = "edit" + item.mID } new{@class="buttonID"})%> But it doesn't work. Because it only excutes the onclick event of a tag, the href attribute doesn't work.

  • Error when trying to use PDO object

    - by Nate
    EDIT: I'm going to put my code in here due to comments below. So sit tight for a few minutes ;-) Thanks! I'm an inexperienced php programmer and only found out about PDO a few days ago. I'm now trying to port my website code over to using PDO, but I am getting an error when I try to use the PDO object that I create. I'm using a CMS on my website, and it makes building page output kind of complicated, but I've tried to draw the structure of what is being called below: index.php -class myClass defined --method myFunction defined (it gets called on pageload & returns the page output) ---include file1.php ----require_once('mysql_connect.php') (creates pdo object) ----*I can use the pdo object here successfully* ----require_once('file2.php') -----require_once('mysql_connect.php') -----function myFunction2 defined ------*trying to use the pdo object here results in the error* The error I'm getting is: Fatal error: Call to a member function prepare() on a non-object in /home/rgcpanel/public_html/account/account_functions.php on line 147 Any idea what's going on?

  • JQuery: show div on radiobutton select

    - by nav
    Hi, I am trying to use JQuery to show a div when the user selects a particular radio button (Other) within a radiobutton group. The html is below <div id="countries"> <input id="Washington_D.C" TYPE="RADIO" NAME="location" VALUE="Washington">Washington D.C</input> <input id="Other" TYPE="RADIO" NAME="location" VALUE="">Other</input> <div id="other locations" style="display: none"> </div> </div> Using the JQuery code: $(document).ready(function(){ $("radio[@name='location']").change(function(){ if ($("radio[@name='location']:checked").val() == 'Other') $("#county_drop_down").show(); }); }); But its not showing the div 'other locations' when I select the radiobutton'Other'....

  • Malloc to a CGPoint Pointer throwing EXC_BAD_ACCESS when accessing

    - by kdbdallas
    I am trying to use a snippet of code from a Apple programming guide, and I am getting a EXC_BAD_ACCESS when trying to pass a pointer to a function, right after doing a malloc. (For Reference: iPhone Application Programming Guide: Event Handling - Listing 3-6) The code in question is really simple: CFMutableDictionaryRef touchBeginPoints; UITouch *touch; .... CGPoint *point = (CGPoint *)CFDictionaryGetValue(touchBeginPoints, touch); if (point == NULL) { point = (CGPoint *)malloc(sizeof(CGPoint)); CFDictionarySetValue(touchBeginPoints, touch, point); } Now when the program goes into the if statement it assigns the 'output' of malloc into the point variable/pointer. Then when it tries to pass point into the CFDictionarySetValue function it crashes the application with: Program received signal: “EXC_BAD_ACCESS”. Someone suggested not doing the malloc and pass the point var/pointer as: &point, however that still gave me a EXC_BAD_ACCESS. What I am (and it looks like Apple) doing wrong??? Thanks in advance.

  • PHP Mcrypt - Encrypting / Decrypting file

    - by whitman6732
    Trying to write a couple of functions that will encrypt or decrypt a file and am using the class found here to try and accomplish this: http://www.itnewb.com/v/PHP-Encryption-Decryption-Using-the-MCrypt-Library-libmcrypt The encryption function below seems to work, in that it appears to encrypt the file and place it in the intended directory. I'm trying to decrypt the file now, and it just dies with the message "Failed to complete decryption" (which is coded in there...) There's nothing in the php error logs, so I'm not sure why it's failing, but as mcrypt is entirely new to me, I'm more than inclined to believe I'm doing something wrong here... Here are the functions: //ENCRYPT FILE function encryptFile() { global $cryptastic; $pass = PGPPASS; $salt = PGPSALT; $key = $cryptastic->pbkdf2($pass, $salt, 1000, 32) or die("Failed to generate secret key."); if ($handle = opendir(PATH.'/ftpd')) { while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { $newfile = PATH.'/encrypted/'.$file.'.txt'; $msg = file_get_contents(PATH.'/ftpd/'.$file); $encrypted = $cryptastic->encrypt($msg, $key) or die("Failed to complete encryption."); $nfile = fopen($newfile, 'w'); fwrite($nfile, $encrypted); fclose($nfile); unlink(PATH.'/ftpd/'.$file); } } closedir($handle); } //DECRYPT FILE function inFTP() { global $cryptastic; $pass = PGPPASS; $salt = PGPSALT; $key = $cryptastic->pbkdf2($pass, $salt, 1000, 32) or die("Failed to generate secret key."); if ($handle = opendir(PATH.'/encrypted')) { while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { $newfile = PATH.'/decrypted/'.$file; $msg = PATH.'/encrypted/'.$file; $decrypted = $cryptastic->decrypt($msg, $key) or die("Failed to complete decryption."); $nfile = fopen($newfile, 'w'); fwrite($nfile, $decrypted); fclose($nfile); //unlink(PATH.'/encrypted/'.$file); } } closedir($handle); } //$crypt->decrypt($file); }

  • Is there anyway to enable MultiSelect in the StyledTextCtrl

    - by John Baker
    I've noticed that the StyledTextControl (Scintilla basically) in wxWidgets has a great feature that allows multi-selections of text, just like TextMate. However wxRuby doesn't seem to have the function calls to support that feature. I'm wonder if there is a way to enable it or if there might be a way I could rewrite that wrapper to include that function. It seems strange that they would purposely omit that since they are seemingly pretty exhaustive on most functions calls. Any insight on this would be greatly appreciated. I'm trying to write an open source TextMate clone in Ruby and it's gonna be pretty hard without MultiSelect, I could probably hack something together but it'd be ugly. Thanks ahead of time.

  • PHP Associative Array Duplicate Key?

    Hello, I have an associative array, however when I add values to it using the below function it seems to overwrite the same keys. Is there a way to have multiple of the same keys with different values? Or is there another form of array that has the same format? I want to have 42=56 42=86 42=97 51=64 51=52 etc etc function array_push_associative(&$arr) { $args = func_get_args(); foreach ($args as $arg) { if (is_array($arg)) { foreach ($arg as $key => $value) { $arr[$key] = $value; $ret++; } }else{ $arr[$arg] = ""; } } return $ret; }

  • VBA Macro On Timer style to run code every set number of seconds, i.e. 120 seconds

    - by FinancialRadDeveloper
    I have a need to run a piece of code every 120 seconds. I am looking for an easy way to do this in VBA.

  • making certain cells of an ExtJS GridPanel un-editable

    - by synchronicity
    I currently have a GridPanel with the Ext.ux.RowEditor plugin. Four fields exist in the row editor: port, ip address, subnet and DHCP. If the DHCP field (checkbox) of the selected row is checked, I need to make the other three fields un-editable. I've been trying to perform this code when the beforeedit event is triggered, but to no avail... I've only found ways to make the entire column un-editable. My code so far: this.rowEditor.on({ scope: this, beforeedit: this.checkIfEditable }); checkIfEditable:function(rowEditor, rowIndex) { if(this.getStore().getAt(rowIndex).get('dhcp')) { // this function makes the entire column un-editable: this.getColumnModel().setEditable(2, false); // I want to make only the other three fields of the current row // uneditable. } } Please let me know if any clarification is needed. Any help potentially extending RowEditor to accomplish the target functionality would be greatly appreciated as well!

  • A controller problem using a base CRUD model

    - by rkj
    In CodeIgniter I'm using a base CRUD My_model, but I have this small problem in my browse-controller.. My $data['posts'] gets all posts from the table called "posts". Though the author in that table is just a user_id, which is why I need to use my "getusername" function (gets the username from a ID - the ID) to grab the username from the users table. Though I don't know how to proceed from here, since it is not just one post. Therefore I need the username to either be a part of the $data['posts'] array or some other smart solution. Anyone who can help me out? function index() { $this->load->model('browse_model'); $data['posts'] = $this->browse_model->get_all(); $data['user'] = $this->browse_model->getusername(XX); $this->load->view('header'); $this->load->view('browse/index', $data); $this->load->view('footer'); }

  • Problem with a SQL statement

    - by benwad
    I'm trying to enter values into a database table using a form and a PHP function. The PHP seems to be fine as the SQL statement it creates looks okay, but the database always throws up an error. This is the SQL statement that my code has generated (with arbitrary values): INSERT INTO Iteminfo ('itemName', 'itemSeller', 'itemCategory', 'itemDescription', 'itemPrice', 'itemPostage', 'itemBegin', 'itemEnd', 'buynow', 'itemPicture') values ('gorillaz album', 'ben', 'music', 'new one ', '5.00', '1.00', '2010-03-15 14:59:51', '2010-03-16 14:59:51', '0', 'http://www.thefader.com/wp-content/uploads/2010/01/gorillaz-plastic-beach.jpg') This throws up an error both when I use the PHP function to evaluate the query and also when I use phpMyAdmin to enter the query manually. However, I can't see anything wrong with it. Can anyone shed some light on this? All of the fields are VARCHAR values, except for itemPrice and itemPostage (which are stored as DECIMAL(4,2)) and the itemBegin and itemEnd, which are stored as DATETIMEs.

  • xsl with javascript

    - by Vignesh
    I've a file with xml data. And I want to generate a report out of it. I tried to integrate xsl with java script, but can I get a handle of individual data elements in xsl and pass it on to a java script function. Lets say <value>true</value> is in the xml and I want to pass it on to a javascript function while doing something like this in xsl. <xsl:for-each select="/valgroup"> <xsl:value-of select="value"/> </xsl:for-each> The alternative is to parse the xml in java script and get the values, I've got little idea of how to integrate it with xsl. Are there any java script libraries. I've seen my libraries that run on servers(AJAXSLT), but I need something that runs locally. I'm a new to xslt, so consider this a worthy question.

  • Variable alpha blending in pylab

    - by Hooked
    How does one control the transparency over a 2D image in pylab? I'd like to give two sets of values (X,Y,Z,T) where X,Y are arrays of positions, Z is the color value, and T is the transparency to a function like imshow but it seems that the function only takes alpha as a scalar. As a concrete example, consider the code below that attempts to display two Gaussians. The closer the value is to zero, the more transparent I'd like the plot to be. from pylab import * side = linspace(-1,1,100) X,Y = meshgrid(side,side) extent = (-1,1,-1,1) Z1 = exp(-((X+.5)**2+Y**2)) Z2 = exp(-((X-.5)**2+(Y+.2)**2)) imshow(Z1, cmap=cm.hsv, alpha=.6, extent=extent) imshow(Z2, cmap=cm.hsv, alpha=.6, extent=extent) show() Note: I am not looking for a plot of Z1+Z2 (that would be trivial) but for a general way to specify the alpha blending across an image.

  • Jquery selectors by CSS class in IE is really slow--workarounds?

    - by Sam Lee
    I have a web app where I have several elements with class="classA". I want to select and apply a function to all of them. I am doing the obvious thing, which is $(".classA").each(function () { ... }). This works just fine in Chrome/Safari/Firefox but is really slow in IE. It turns out IE has serious performance issues when selecting things by CSS class in jQuery. I was wondering if anyone has suggestions on good ways to deal with this. I can't use ID selectors because there can be multiple DOM elements I want to select.
