• How do I do an AJAX post to a url within a class library but not the same IIS Web Application?

  - by Mark Adesina

  I have been working with ajax and there has been no problems below is how my ajax post code look like: $.ajax({ type: "POST", url: '<%=ResolveUrl("TodoService.asmx/CreateNewToDo")%>', data: jsonData, contentType: "application/json; charset=utf-8", datatype: "json", success: function () { //if (msg.d) { $('#ContentPlaceHolder1_useridHiddenField').val(""); $('#ContentPlaceHolder1_titleTextBox').val(""); $('#ContentPlaceHolder1_destTextBox').val(""); $('#ContentPlaceHolder1_duedateTextBox').val(""); alert('Your todo has been saved'); // } }, error: function (msg) { alert('There was an error processing your request'); } }); However, the problem came up when I try to get the url to a webservice that is located in a class library within the same solution.

• PHP: why uniqid returned value is only 13 digits long

  - by Marco Demaio

  uniqid() function returns a 13 digits long hexadecimal number. According to the spec in php.net site, the function uses microtime to generate the unique value. But microtime returns numbers in string format as the following one: "0.70352700 12689396875" which are basically the microseconds and the seconds elapsed since 1970. This is a 9+11 digits decimal number. Converting a 20 decimal number into hex would result in a 16 digits hexadecimal NOT a 13 digits one. I also thought to take out the "0." part that seem to never change, and the last two digits of the microsec part that seem to remain always "00". Doing this the decimal number would be only 9+11-3 digits long, but still a decimal number of 17 digits when converted into hex would result in 14 digits hexadecimal number NOT 13. You probably think I'm crazy in asking such a thing, but I'm concerned about using uniqid, unique values are important to be unique, a duplicated value could screw up an entire application.

• HttpContext.Current.Request.UserHostName is empty when called from a class

  - by John Galt

  I have various web pages that need to build up a URL to display or place it in an emitted email message. The code I inherited had this value for the name of the webserver in a Public Const in a Public Class called FixedConstants. For example: Public Const cdServerName As String = "WEBSERVERNAME" Trying to improve on this, I wrote this: Public Class UIFunction Public Shared myhttpcontext As HttpContext Public Shared Function cdWebServer() As String Dim s As New StringBuilder("http://") Dim h As String h = String.Empty Try h = Current.Request.ServerVariables("REMOTE_HOST").ToString() Catch ex As Exception Dim m As String m = ex.Message.ToString() 'Ignore this should-not-occur thingy End Try If h = String.Empty Then h = "SomeWebServer" End If s.Append(h) s.Append("/") Return s.ToString() End Function I've tried different things while debugging such as HttpContext.Current.Request.UserHostName and I always get an empty string which pumps out my default string "SomeWebServer". I know Request.UserHostName or Request.ServerVariables("REMOTE_HOST") works when invoked from a page but why does this return empty when invoked from a called method of a class file (i.e. UIFunction.vb)?

• Using Facebook Connect with jQTouch?

  - by Volmar

  Hi, i'm starting a new jQTouch-project now and i'm thinking of using facebook connect to make it easier for users to register with my site. do anyone have any experience with this? I'm using the Facebook PHP SDK (from github), and i first tried to use it with the built in example, it worked good. i later tried it with jQTouch (the latest build from the SVN). when i create the log in/log out link inside a ul.roundedli element it does not work because jQTouch have some special function that handles links clicked inside a li-element. how can i go around this function and make it work with the connect-link, i'm using the display=touch version of the autentication dialog. when i add the link outside of the ul.roundedli-element it works in desktop safari but not in mobile safari. any ideas?

• Using Jquery.Form Plugin + MultiFile to automatically upload a single file

  - by Alan Neal

  I wanted to find a way to upload a single file*, in the background, have it start automatically after file selection, and not require a flash uploader, so I am trying to use two great mechanisms (jQuery.Form and JQuery MultiFile) together. I haven't succeeded, but I'm pretty sure it's because I'm missing something fundamental. Just using MultiFile, I define the form as follows... <form id="photoForm" action="image.php" method="post" enctype="multipart/form-data"> The file input button is defined as... <input id="photoButton" "name="sourceFile" class="photoButton max-1 accept-jpg" type="file"> And the Javascript is... $('#photoButton').MultiFile({ afterFileSelect: function(){ document.getElementById("photoForm").submit(); } }); This works perfectly. As soon as the user selects a single file, MultiFile submits the form to the server. If instead of using MultiFile, as shown above, let's say I include a Submit button along with the JQuery Form plugin defined as follows... var options = { success: respondToUpload }; $('#photoForm').ajaxForm(options); ... this also works perfectly. When the Submit button is clicked, the form is uploaded in the background. What I don't know how to do is get these two to work together. If I use Javascript to submit the form (as shown in the MultiFile example above), the form is submitted but the JQuery.Form function is not called, so the form does not get submitted in the background. I thought that maybe I needed to change the form registration as follows... $('#photoForm').submit(function() { $('#photoForm').ajaxForm(options); }); ...but that didn't solve the problem. The same is true when I tried .ajaxSubmit instead of .ajaxForm. What am I missing? BTW: I know it might sound strange to use MultiFile for single-file uploads, but the idea is that the number of files will be dynamic based on the user's account. So, I'm starting with one but the number changes depending on conditions.

• random products instead of related products in magento

  - by abnab

  BElow is the function that selects related product of a single product. I wanted it to work in such a way that if there are no related products other random products will be added to the array. Random could be other products of the same category and if there is no procut in the same category we could fetch from other categories. protected function _prepareData() { $product = Mage::registry('product'); /* @var $product Mage_Catalog_Model_Product */ $this->_itemCollection = $product->getRelatedProductCollection() ->addAttributeToSelect('required_options') ->addAttributeToSort('position', Varien_Db_Select::SQL_ASC) ->addStoreFilter() ; if (Mage::helper('catalog')->isModuleEnabled('Mage_Checkout')) { Mage::getResourceSingleton('checkout/cart')->addExcludeProductFilter($this->_itemCollection, Mage::getSingleton('checkout/session')->getQuoteId() ); $this->_addProductAttributesAndPrices($this->_itemCollection); } // Mage::getSingleton('catalog/product_status')->addSaleableFilterToCollection($this->_itemCollection); Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($this->_itemCollection); $this->_itemCollection->load(); foreach ($this->_itemCollection as $product) { $product->setDoNotUseCategoryId(true); } return $this; } Thanks Abnab

• jQuery event to trigger action when a div is made visible

  - by frankadelic

  I'm using jQuery in my site and I would like to trigger certain actions when a certain div is made visible. Is it possible to attach some sort of "isvisible" event handler to arbitrary divs and have certain code run when they the div is made visible? I would like something like the following pseudocode: $(function() { $('#contentDiv').isvisible(function() { alert("do something"); }); }); The alert("do something") code should not fire until the contentDiv is actually made visible. Thanks.

• PHP convert decimal into fraction and back?

  - by John Isaacks

  I want the user to be able to type in a fraction like: 1/2 2 1/4 3 And convert it into its corresponding decimal, to be saved in MySQL, that way I can order by it and do other comparisons to it.

• Dynamically changing Wordpress permalinks

  - by conrad

  i am trying to write a plugin which rewrites "post_link", "page_link", "category_link", "tag_link" with an action hook on wordpress. it's similar to this: add_action("post_link", "the_rewrite_function"); function the_rewrite_function($link) { ... return $new_link; } for example the permalink to the post is: http://www.example.com/2010/11/11/the-post-name/ i am changing it with the function to: http://www.example.com/2010/11/11/the-awesome-post-name/ of course when i do this the new permalink is going to 404 (as expected) what can i do to make the new permalink go to the original and working one? Please consider this: it should work on any permalink structure so a permalink structure spesific solution won't do any good. i need to solve this inside the plugin. thanks!

• How do you implement file drag-and-drop upload in Google Chrome?

  - by Chris R

  I've found several tutorials online about implementing file drag/drop with Firefox 3.6 (they involve using a FileReader object to get the file binary data). However, I cannot create a FileReader object in Chrome on Windows or Mac. Does anyone know what the API is to read and manipulate data from a drag-and-dropped file in Chrome? If I can get the binary data of the file, I already have the rest of the code to perform the upload. Note: I've also tried using the getAsBinary() function call on the file object of the drag event (event.dataTransfer.file) but I believe that is a Mozilla-specific function and not implemented in Chrome. Also, I'm not interested in a solution using google gears or one that requires a user to select files from a dialog. I'm specifically trying to implement a drag-and-drop file upload.

Currently, my database structure is the following: idcomponente | quantidade After fetching the values in PHP, I want to know how can I encode them using JSON (with multiple rows, using the same names) so I can read them using jQuery.post(). $.post('test.php',{id:id},function(data){ //READ data HERE }); Thanks in advance Edit: So far, I made this: $.post('edit/producomponentes.php',{id:id},function(data){ console.log(data); }); Logs this: [Object { componente="1", quantidade="2"}, Object { componente="3", quantidade="3"}] Now how can I go through each row and fetch their properties?

• CodeIgniter - Post multiple arrays to controller

  - by Bobe

  I have a dynamically generated form that allows users to enter new data and edit existing data. When the form is submitted, it collates the input values and groups them according to whether they are new or not, the former being denoted by class="new-entry". So the function generates two arrays: updateData and insertData. Both arrays are of similar formats: [ 0: { 'id' = 1, 'value' = foo }, 1: { 'id' = 1, 'value' = 'bar' }, etc... ] I am combining them into a new array object to send via ajax to the controller: var postData = { 'update_data': updateData, 'insert_data': insertData }; Then in the ajax call: $.post(url, postData, function() { // some code }); However, in the controller, doing print_r($this->input->post()) or print_r($_POST) as a test only returns Array(). Even $this->input->post('update_data') returns nothing. How can I retrieve these arrays in the controller?

• Using respond_to ... format.json and jQuery Form Plugin by malsup

  - by Topher Fangio

  Hello all, I'm having a tad bit of trouble getting the jQuery Form Plugin to work properly with a file-upload field. When I use the plugin to submit the form without a file-upload field, the format.json portion of the respond_to do |format| block is called properly. However, by adding the file-upload field, it only executes the format.html portion which makes my javascript code think that an error has occurred. Has anyone run into this before or know a way to force the plugin to always use json? Alternatively, can I modify the url that the plugin uses to force Rails to render the json? Thanks very much for any help! Code below: # app/controllers/details_controller.rb def create @detail = Detail.new(params[:detail]) style = params[:detail_style].to_sym || :thumb data = { :id => '5', :url => 'test.rails' } respond_to do |format| if @detail.save flash[:notice] = 'Your image has been saved.' data = { :id => @detail.id, :url => @detail.data.url(style) } format.html { redirect_to :action => 'index' } format.json { render :json => "<textarea>#{data.to_json}</textarea>", :status => :created } else format.html { render :action => 'new' } format.json { render :json => @detail.errors, :status => :unprocessable_entity } end end end /* app/views/sidebar/_details.html.erb (excerpt) */ <% form_for(Detail.new, :html => { :multipart => true } ) do |f| %> <%= hidden_field_tag 'detail_style', 'thumb' %> <%= f.label :image, "Recent Images" %> <%= f.file_field :image%> <p> <%= f.submit "Upload" %> </p> <% end %> <script> $(document).ready(function() { var options = { dataType: 'json', success: function(json, statusText) { console.log("success: " + json); }, error: function(xhr, statusText, errorThrown) { console.log("error: " + xhr.responseText); } }; $('#new_detail').ajaxForm(options); });

• Creating Mock object of Interface with type-hint in method fails on PHPUnit

  - by Mark

  I created the following interface: <?php interface Action { public function execute(\requests\Request $request, array $params); } Then I try to make a Mock object of this interface with PHPUnit 3.4, but I get the following error: Fatal error: Declaration of Mock_Action_b389c0b1::execute() must be compatible with that of Action::execute() in D:\Xampp\xampp\php\PEAR\PHPUnit\Framework\TestCase.php(1121) : eval()'d code on line 2 I looked through the stack trace I got from PHPUnit and found that it creates a Mock object that implements the interface Action, but creates the execute method in the following way: <?php public function execute($request, array $params) As you can see, PHPUnit takes over the array type-hint, but forgets about \requests\Request. Which obviously leads to an error. Does anyone knows a workaround for this error? I also tried it without namespaces, but I still get the same error.

• Redirect Output of Capistrano

  - by Eric Lubow

  I have a Capistrano deploy file (Capfile) that is rather large, contains a few namespaces and generally has a lot of information already in it. My ultimate goal is, using the Tinder gem, paste the output of the entire deployment into Campfire. I have Tinder setup properly already. I looked into using the Capistrano capture method, but that only works for the first host. Additionally that would be a lot of work to go through and add something like: output << capture 'foocommand' Specifically, I am looking to capture the output of any deployment from that file into a variable (in addition to putting it to STDOUT so I can see it), then pass that output in the variable into a function called notify_campfire. Since the notify_campfire function is getting called at the end of a task (every task regardless of the namespace), it should have the task name available to it and the output (which is stored in that output variable). Any thoughts on how to accomplish this would be greatly appreciated.

• Chrome extensions: Content script (jQuery) in Youtube does not work properly

  - by Fabian

  I have this: $(document).ready(function() { $("button.yt-uix-expander-arrow").attr("id", "yt-uix-expander-arrow"); $("#yt-uix-expander-arrow").mouseover(function() { alert("Hello"); }); }); injected into Youtube. Using right click inspect element, the <button class="yt-uix-expander-arrow"> has a id="yt-uix-expander-arrow" attribute successfully added to it. However the mouseover event does not trigger. However if I were to change $("#yt-uix-expander-arrow").mouseover() to $(".yt-uix-expander-arrow").mouseover() it works. That's very unusual, because the #yt-uix-expander-arrow id has already been added to the button element. I tested it out on Facebook, adding a id to a class and doing a mouseover() event on the ID and it works. Any idea?
