  • PHP combobox can't save the selected value on Edit Page

    - by bEtTy Barnes
    hello I've got problem with my combobox. It's not saving the selected value in Edit page. Here what I'm working with: private function inputCAR(){ $html = ""; $selectedId = $this->CAR; //$html .= '<option value="Roadmap Accelerator - Core">Roadmap Accelerator - Core</option>'; //$html .= '<option value="Roadmap Accelerator - Optional Core">Roadmap Accelerator - Optional Core</option>'; //$html .= '<option value="Regulatory">Regulatory</option>'; //$html .= '<option value="Mission Critical">Mission Critical</option>'; //$html .= '<option value="Various CARs/Types">Various CARs/types</option>'; $selection = array( "Roadmap Accelerator - Core", "Roadmap Accelerator - Optional Core", "Regulatory", "Mission Critical", "Various CARs/types" ); $html .= '<label for="car">CAR Type</label>'; $html .= HTML::selectStart("car"); foreach($selection as $value){ $text = $value; $html .= HTML::option($value, $text, $selectedId == $value ? true : false); } $html .= HTML::selectEnd(); return $html; } My option function: public static function option($value, $text, $isSelected=false) { $html = '<option value="' . $value . '"'; if($isSelected) { $html .= ' selected="selected"'; } $html .= '>'; $html .= $text; $html .= '</option>'; return $html; } When I first created a record. The selected value from my combobox got saved into the DB then the page refreshed to display. When I went to edit page, to select another value, and clicked save button. On the display page, it's not saving. For example. on Create page I selected Regulatory. then I changed my mind and changed it to Mission Critical on Edit page. On display page it is not changed. I don't know what's wrong or what I'm missing here. Any help is welcome and truly appreciated. Thanks.

  • In Javascript, by what mechanism does setting an Image src property trigger an image load?

    - by brainjam
    One of the things you learn early on when manipulating a DOM using Javascript is the following pattern: var img = new Image(); // Create new Image object img.onload = function(){ // execute drawImage statements here } img.src = 'myImage.png'; // Set source path As far as I know, in general when you set an object property there are no side effects. So what is the mechanism for triggering an image load? Is it just magic? Or can I use a similar mechanism to implement a class Foo that supports a parallel pattern? var foo = new Foo(); // Create new object foo.barchanged = function(){ // execute something after side effect has completed } foo.bar = 'whatever'; // Assign something to 'bar' property I'm vaguely aware of Javascript getters and setters. Is this how Image.src triggers a load?

  • What is the proper way to declare a specialization of a template for another template type?

    - by Head Geek
    The usual definition for a specialization of a template function is something like this: class Foo { [...] }; namespace std { template<> void swap(Foo& left, Foo& right) { [...] } } // namespace std But how do you properly define the specialization when the type it's specialized on is itself a template? Here's what I've got: template <size_t Bits> class fixed { [...] }; namespace std { template<size_t Bits> void swap(fixed<Bits>& left, fixed<Bits>& right) { [...] } } // namespace std Is this the right way to declare swap? It's supposed to be a specialization of the template function std::swap, but I can't tell whether the compiler is seeing it as such, or whether it thinks that it's an overload of it or something.

  • Chrome and Safari strange behaviour in Javascript

    - by mck89
    Hi, i've written this peace of code: var a=function(){ }; a.name="test"; a.prop="test2"; Now if i debug the code with the console: console.log(a.name); console.log(a.prop); In Firefox i get a.name="test" and a.prop="test2", while in Safari and Chrome i get a.prop="test2" but a.name="". It seems that there's no way to assign a "name" property on a function in Webkit browsers. Do you know why? But the most important thing is, do you know a workaround for that?

  • Arbitrary Form Processing with Drupal

    - by Aaron
    I am writing a module for my organization to cache XML feeds to static files to an arbitrary place on our webserver. I am new at Drupal development, and would like to know if I am approaching this the right way. Basically I: Expose a url via the menu hook, where a user can enter in a an output directory on the webserver and press the "dump" button and then have PHP go to drupal and get the feed xml. I don't need help with that functionality, because I actually have a prototype working in Python (outside of Drupal).. Provide a callback for the form where I can do my logic, using the form parameters. Here's the menu hook: function ncbi_cache_files_menu() { $items = array(); $items['admin/content/ncbi_cache_files'] = array( 'title' => 'NCBI Cache File Module', 'description' => 'Cache Guide static content to files', 'page callback' => 'drupal_get_form', 'page arguments' => array( 'ncbi_cache_files_show_submit'), 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } I generate the form in: function ncbi_cache_files_show_submit() { $DEFAULT_OUT = 'http://myorg/foo'; $form[ 'ncbi_cache_files' ] = array( '#type' => 'textfield', '#title' => t('Output Directory'), '#description' => t('Where you want the static files to be dumped. This should be a directory that www has write access to, and should be accessible from the foo server'), '#default_value' => t( $DEFAULT_OUT ), '#size' => strlen( $DEFAULT_OUT ) + 5, ); $form['dump'] = array( '#type' => 'submit', '#value' => 'Dump', '#submit' => array( 'ncbi_cache_files_dump'), ); return system_settings_form( $form ); } Then the functionality is in the callback: function ncbi_cache_files_dump( $p, $q) { //dpm( get_defined_vars() ); $outdir = $p['ncbi_cache_files']['#post']['ncbi_cache_files']; drupal_set_message('outdir: ' . $outdir ); } The question: Is this a decent way of processing an arbitrary form in Drupal? I not really need to listen for any drupal hooks, because I am basically just doing some URL and file processing. What are those arguments that I'm getting in the callback ($q)? That's the form array I guess, with the post values? Is this the best way to get the form parameters to work on? Thanks for any advice.

  • some confusions to singleton pattern in PHP

    - by SpawnCxy
    Hi all, In my team I've been told to write resource class like this style: class MemcacheService { private static $instance = null; private function __construct() { } public static function getInstance($fortest = false) { if (self::$instance == null) { self::$instance = new Memcached(); if ($fortest) { self::$instance->addServer(MEMTEST_HOST, MEMTEST_PORT); } else { self::$instance->addServer(MEM_HOST, MEM_PORT); } } return self::$instance; } } But I think in PHP resource handles will be released and initialized again every time after a request over. That means MemcacheService::getInstance() is totally equal new Memcached() which cannot be called singleton pattern at all. Please correct me if I'm wrong. Regards

  • ASP.NET MVC NullReferenceException when inheriting from a Base Controller

  • pyramid view redirection

    - by ascobol
    This question title may be slightly incorrect but I could not find a better one (yet). I'm trying to integrate Mozilla Persona (browserid) into a Pyramid application. The login process is: user can login on any page by clicking on the login button a popup then shows a login form when the users enters correct login/password, an ajax call is made by the popup to a pyramid view that checks users credentials, and calls pyramid remember function if the check succeeded the browserid javascript code then reloads the current page Now I want to handle the case of a new user subscribing to the web app and present a new view asking for a few more details (desired username, etc) Since the "remember" function is called by an ajax call from the popup, I cannot redirect the user the the "/newuser" page. So every view needs to redirect new users to the "/newuser" url whenever the remembered browserid has no corresponding user in the database. Is there a way to intercept user requests before calling a view to call the "new_user" view instead ? Or maybe my authentication approach is fundamentally incorrect and I should rely on another approach ?

  • Avoid multiple autocomplete calls by wrapping it with SetTimeOut

    - by pixelboy
    Here's my issue : using an autocomplete jQuery plugin, I'd like to avoid multiple ajax requests when user strikes his keynoard by surrounding the $('#query1').autocomplete({ serviceUrl:'/actions/autocomplete?population=salon', minChars:3, maxHeight:300, width:200, clearCache:true, onSelect: function(suggestions,data){ $(".btn1").attr("href", "${pageContext.request.contextPath}/actions/espaceClients?participantId=" + data) } }); with something like var search = false; $('#query1, #query2, #query3').keyup(function(){ if (!search){ search = true; } if (search) { search = false; autocompleteThem(); } }); A you can see, above code is stupid, but it kinda shows what i'm trying to do. In simple words, if user dosen't type anything else in a certain period of time, then you can call autocomplete. I hope i'm being clear, as my brains are a mess...

  • jQuery/javascript events - prototype event handler

    - by Brian M. Hunt
    The following code doesn't work as I intuitively expect it to: function MyObject(input) { input.change(this._foo); this.X = undefined; } MyObject.prototype._foo = function() { alert("This code is never called"); // but if it did this.X = true; } var test_input = $("input#xyz"); // a random, existing input var m = MyObject(test_input); // attach handler (or try to) test_input.change(); // trigger event alert(m.X); // undefined I'd expect that _foo() would be called (and, if that ever happens, that the this variable in _foo() would be an instantiation of MyObject. Does anyone know why this doesn't work, and of any alternative pattern for passing an object to an event handler? Thank you for reading. Brian

  • Using new Image().src for click tracking

    - by razass
    I am attempting to figure out why this click tracker isn't working. The code was written by another developer so I am not entirely sure if this ever did work. function trackSponsor(o, p) { (new Image()).src = PATH_BASE + 'click/' + p + '/' + o + "?_cache=" + (+(new Date())); return false; } From what I can gather is that when this function is called it 'creates a new image' to fire a php script asynchronously. According to Firebug, the request is made however it is 'aborted' ~30ms in. The odd thing is that it will 'sometimes' work as in 1 in every 10+ regardless of the browser. I would much rather fix this so that it works instead of re-writing it as an ajax request. Any help is appreciated. Thanks in advance.

  • Haskell: variant of `show` that doesn't wrap String and Char in quotes

    - by Joey Adams
    I'd like a variant of show (let's call it label) that acts just like show, except that it doesn't wrap Strings in " " or Chars in ' '. Examples: > label 5 "5" > label "hello" "hello" > label 'c' "c" I tried implementing this manually, but I ran into some walls. Here is what I tried: {-# LANGUAGE FlexibleInstances #-} {-# LANGUAGE UndecidableInstances #-} module Label where class (Show a) => Label a where label :: a -> String instance Label [Char] where label str = str instance Label Char where label c = [c] -- Default case instance Show a => Label a where label x = show x However, because the default case's class overlaps instance Label [Char] and instance Label Char, those types don't work with the label function. Is there a library function that provides this functionality? If not, is there a workaround to get the above code to work?

  • Force redraw before long running operations

    - by Joshua
    When you have a button, and do something like: Private Function Button_OnClick Button.Enabled = False [LONG OPERATION] End Function Then the button will not be grayed, because the long operation prevents the UI thread from repainting the control. I know the right design is to start a background thread / dispatcher, but sometimes that's too much hassle for a simple operation. So how do I force the button to redraw in disabled state? I tried .UpdateLayout() on the Button, but it didn't have any effects. I also tried System.Windows.Forms.DoEvents() which normally works when using WinForms, but it also had no effect.

  • C# Event Handlers automatically created by WinForms Designer

    - by RHaguiuda
    Just moved from VB.NET to C#. In VB to connect and Event Handler to a Sub we use the Handles clause. From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code: this.button1.Click += new System.EventHandler(this.button1_Click); But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class with control resides. Is this correct? Am I missing something here?
