  • Explode URL Query String Issue

    - by Ian McAbee
    PHP newbie here.. I am trying to create a function where the user is redirected back to the previous page after adding an item to their cart. However, when they are redirected back with the code below it leaves a duplicate of the directory (ie. example.com/catalog/garden-tools/garden-tools function custom_add_to_cart_redirect() { $_SERVER['REQUEST_URI_PATH'] = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH); $url = explode('/', rtrim($_SERVER['REQUEST_URI_PATH'], '/')); return $url[3]; } A print_r reveals the following: Array ( [0] => [1] => thefarmshop [2] => catalog [3] => garden-tools [4] => gardening-glove ) What could the issue be?

  • Getting HTMLUnknownElement with jQuery.find() and an XML Document

    - by Tom
    I'm attempting to load up an XML document (specifically an RSS feed) via an Ajax request, parse it, and insert some information based on said feed into my page. The code works fine in Firefox, Opera, Chrome, and Safari, but not IE7. Go figure. After doing some initial debugging, I've found that the XML string is being retrieved via the request, and the specific node type I'm getting when trying to parse nodes out of the document is HTMLUnknownElement. Here's the relevant code: $.get('feed.php', function(oXmlDoc) { var titles = $(oXmlDoc).find('title'); var dates = $(oXmlDoc).find('pubDate'); for(var i = 0; i < 5; i++) { parseNodes(titles[i].firstChild.nodeValue, dates[i].firstChild.nodeValue)); } }); The parseNodes function is never actually being hit because IE cannot access firstChild and, consequently, nodeValue. Thanks in advance for any ideas and/or suggestions on how to address this.

  • Add method to Array in Javascript

    - by user1167650
    Is it possible to add a method to an array() in javascript? (I know about prototypes, but I don't want to add a method to every array, just one in particular). The reason I want to do this is because I have the following code function drawChart() { //... return [list of important vars] } function updateChart(importantVars) { //... } var importantVars = drawChart(); updateChart(importantVars); And I want to be able to do something like this instead: var chart = drawChart();<br> chart.redraw(); I was hoping there was a way I could just attach a method to what i'm returning in drawChart(). Any way to do that?

  • Haskell - generating all paths between nodes

    - by user1460863
    I need to build a function, which return all paths between certain nodes. connect :: Int -> Int-> [[(Int,Int)]] Data.Graph library gives me usefull function 'buildG' which builds graph for me. If I call let g = buildG (1,5) [(1,2),(2,3),(3,4),(4,5),(2,5)], I will get an array where every node is mapped to his neighbours. An example: g!1 = [2] g!2 = [3,5] .. g!5 = [] I was trying to do it using list comprehensions, but I am not very good in haskell and I am getting typing error which I can't repair. connect x y g | x == y = [] | otherwise = [(x,z) | z <- (g!x), connect z y g] I don't need to worry at this moment about cycles. Here is what I want to get: connect 1 5 g = [[(1,2),(2,3),(3,4),(4,5)],[(1,2),(2,5)]]

"'"); $check = mysql_fetch_array($q); $result = count($check); echo "RESULT:" . $result;

  • Is this a good approach to dealing with tagging?

    - by Mel
    Can this code be optimized or re-factored? Is this an optimal approach to tagging? The following code is a callback in my posts model. It creates a record that associates a tag with a post in a QuestionsTags joiner table. When necessary, if a given tag does not already exist in the tags table, the function creates it, then uses its id to create the new record in the QuestionsTags table. The difficulty with this approach is the QuestionsTags table depends on data in the tags table which may or may not exist. The function assumes the following tables: tags(id, tagName), posts(tags) // Comma delimited list questionsTags(postId, tagId) The idea is to loop over a delimited list of tags submitted with a post and check to see if each tag already exists in the tags table If tag exists: Check to see if there's already a QuestionTag record for this post and this tag in the QuestionTags table. If yes, do nothing (the association already exists) If no, create a new QuestionTag record using the id of the existing tag and the postId If tag does not already exist: Create the new tag in the tags table Use its id to create a new QuestionsTags record Code /** * @hint Sets tags for a given question. **/ private function setTags() { // Loop over the comma and space delmited list of tags for (local.i = 1; local.i LTE ListLen(this.tags, ", "); local.i = (local.i + 1)) { // Check if the tag already exists in the database local.tag = model("tag").findOneByTagName(local.i); // If the tag exists, look for an existing association between the tag and the question in the QuestionTag table if (IsObject(local.tag)) { local.questionTag = model("questionTag").findOneByPostIdAndTagId(values="#this.postId#,#local.tag.id#"); // If no assciatione exists, create a new QuestionTag record using the tagId and the postId if (! IsObject(local.questionTag)) { local.newQuestionTag = model("questionTag").new(postId = this.id, tagId = local.tag.id); // Abort if the saving the new QuestionTag is unsuccesful if (! local.newQuestionTag.save()) { return false; } } } // If the tag does not exist create it else { local.newTag = model("tag").new(tagName = local.i, userId = this.ownerUserId); // Abort if the the new tag is not saved successfully if (! local.newTag.save()) { return false; } // Otherwise create a new association in the QuestionTags table using the id of the newly created tag and the postId local.newQuestionTag = model("questionTag").new(postId = this.id, tagId = local.newTag.id); // Abort if the new QuestionTag does not save correctly if (! local.newQuestionTag.save()) { return false; } } } } FYI: I'm using CFWheels in my application, which explains the ORM functions used.

  • Do I need to declare all my JQuery prototypes in a JQueryStatic definition file with typescript?

    - by Marilou
    I have the following code: ///<reference path="../typescript/jquery.d.ts" /> function addThemePrototypes() { var templateSetup = new Array(); $.fn.addTemplateSetup = function(func, prioritary) { if (prioritary) { templateSetup.unshift(func); } else { templateSetup.push(func); } }; } When I try to add the following: $('a').addTemplateSetup( Into this same file I notice there is no intellisense and typescript does not seem to know about the addTemplateSetup prototype that I just added. Is this the correct way for it to work or do I always need to add things like the definition for addTemplateSetup to an JQueryStatic definition file and then include that?

  • jQuery/Javascript problem with IE

    - by Shadyn
    I have two radio buttons each with a unique ID. When one is clicked, I would like to add $10 to a total. When the other is clicked, we go back to the original total price. My jquery looks like this: function check_ceu() { var price = <%= conference_price %>; if($('#ceu_yes').is(':checked')){ $('#total').val(parseFloat(price) + 10) } else{ $('#total').val(price) } } I have this function bound to document.ready (for page refreshes) and also the onchange handler of the radio buttons. In FF and Chrome this works fine. In IE, when the radio button with ID of "ceu_yes" is checked nothing happens, then when clicking back to the other radio button, 10 is added. So in essence, IE has the checkbox functionality reversed. Below is my code for the buttons: <input type="radio" name="ceu" id="ceu_yes" value="1" onchange="check_ceu()" /> $10 <input type="radio" name="ceu" id="ceu_no" value="0" checked="checked" onchange="check_ceu()" /> No, thank you Any ideas on this?

  • Any good idioms for error handling in straight C programs?

    - by Will Hartung
    Getting back in to some C work. Many of my functions look like this: int err = do_something(arg1, arg2, arg3, &result); With the intent the result gets populated by the function, and the return value is the status of the call. The darkside is you get something naive like this: int err = func1(...); if (!err) { err = func2(...); if (!err) { err = func3(...); } } return err; I could macro it I suppose: #define ERR(x) if (!err) { err = (x) } int err = 0; ERR(func1(...)); ERR(func2(...)); ERR(func3(...)); return err; But that only works if I'm chaining function calls, vs doing other work. Obviously Java, C#, C++ have exceptions that work very well for these kinds of things. I'm just curious what other folks do and how other folks do error handling in their C programs nowadays.

  • Keyup attribute 'name' change not working

    - by dclowd9901
    Hey guys, I've got what I imagine is a simple question, but for some reason, I can't get it working right. Expected Behavior: I type characters into a field, and, through a function, those characters are translated into the value of the name HTML attribute. Actual Behavior: Reflected in Firebug, the value doesn't change or update. The Code: $('input').live('keyup', function() { var name_value = $(this).val().toLowerCase(); $(this).attr('name', name_value); }); Just a side note: I'm using .live() because the element can be cloned, and those clones need to also be able to take on the properties of this .keyup event. Any ideas?

  • How to trigger an event ONLY if both dropdowns are selected?

    - by DaveDev
    I have a dropdown select list on my page of class="TypeFilter". I have a jQuery event that fires when a value in that list is selected. $(".TypeFilter").change(function() { // Extract value from TypeFilter and update page accordingly )); I now have to add another list to the page, and I want to implement functionality which will prevent the .change(function() from running unless both are selected. In both lists the first option in the list is some text instructing the user to select one of the items, so I was thinking of just writing some logic to test that both lists have a selected index greater than 0. I think this is a touch unclean though, especially considering that other pages that have a TypeFilter use the same logic. Is there any nifty functionality in jQuery that can do this?

  • movedown method not saving new position - cakephp tree

    - by Ryan
    Hi everyone, I am experiencing a problem that has popped up recently and is causing quite a bit of trouble for our system. The app we have relies on using the movedown method to organize content, but as of late it has stopped working and began to generate the following warning: Warning (2): array_values() [<a href='function.array-values'>function.array-values</a>]: The argument should be an array in [/usr/local/home/cake/cake_0_2_9/cake/libs/model/behaviors/tree.php, line 459] The line being referenced: list($node) = array_values($Model->find('first', array( 'conditions' => array($scope, $Model->escapeField() => $id), 'fields' => array($Model->primaryKey, $left, $right, $parent), 'recursive' => $recursive ))); The line calling the method: $this->movedown($id,abs((int)$position)); I have exhausted every idea I could come up with. Has anyone else crossed this issue before? Any help, or pointing in a direction would be much appreciated!

  • does overload operator-> a compile time action?

    - by Brent
    when I tried to compile the code: struct S { void func2() {} }; class O { public: inline S* operator->() const; private: S* ses; }; inline S* O::operator->() const { return ses; } int main() { O object; object->func(); return 0; } there is a compile error reported: D:\code>g++ operatorp.cpp -S -o operatorp.exe operatorp.cpp: In function `int main()': operatorp.cpp:27: error: 'struct S' has no member named 'func' it seems that invoke the overloaded function of "operator-" is done during compile time? I'd add "-S" option for compile only.

  • Programmatically get valid switch/case values

    - by craigim
    When MATLAB scans through cases in a switch/case block, does it remember the values that it skips, and is it possible to access that list? I have a few functions with long switch\case block and I would like to have them return a list of valid case values if they make it down to otherwise. For instance, I have a function that returns a set of optical constants for a material. It currently has about 20 different materials and it is growing as I consider new ones. I realize I can brute-force it and just re-type all of the valid cases into a cell array under otherwise and have the function throw an error and return the list of valid responses, but maintaining both lists without errors or laziness creeping in over time is challenging.

  • Get next key-value pair in an object

    - by captainclam
    So, given a key, I want to find the next property in an object. Then, I want to return the value of the NEXT property. I can not rely on the keys to be ordered or sequential (they're uuids). Please see below for trivial example of what I want: var db ={ a: 1, b: 2, c: 3 } var next = function(db, key) { // ??? } next(db, 'a'); // I want 2 next(db, 'b'); // I want 3 I also want a prev() function, but I'm sure it will be the same solution. This seems like such a trivial problem but I can't for the life of me figure out how to do it. Happy for the solution to use underscore.js or be written in coffeescript :)

  • Array-size macro that rejects pointers

    - by nneonneo
    The standard array-size macro that is often taught is #define ARRAYSIZE(arr) (sizeof(arr) / sizeof(arr[0])) or some equivalent formation. However, this kind of thing silently succeeds when a pointer is passed in, and gives results that can seem plausible at runtime until things mysteriously fall apart. It's all-too-easy to make this mistake: a function that has a local array variable is refactored, moving a bit of array manipulation into a new function called with the array as a parameter. So, the question is: is there a "sanitary" macro to detect misuse of the ARRAYSIZE macro in C, preferably at compile-time? In C++ we'd just use a template specialized for array arguments only; in C, it seems we'll need some way to distinguish arrays and pointers. (If I wanted to reject arrays, for instance, I'd just do e.g. (arr=arr, ...) because array assignment is illegal).
