I have a website (Flash) localized into a dozen of languages and I want to auto-define a default value depending on the user's browser settings in order to minimize the steps to access the content. FYI, I cannot use server-scripts due to proxy restrictions, so I guess JavaScript or ActionScript would be appropriate to solve the problem. Questions: What would be the best method to 'guess' the user's locale ? Are there any existing simple classes/functions that could help me out (no complex localization bundles) ? Specially to break down all the possible languages into a smaller number (the translations I have) on a smart way . To which point can I trust such a solution ? Any other workarounds or suggestions ? Thanks in advance! Source: Tips4all

The behavior of "this" when function bar is called is baffling me. See the code below. Is there any way to arrange for "this" to be a plain old js object instance when bar is called from a click handler, instead of being the html element? // a class with a method function foo() { this.bar(); // when called here, "this" is the foo instance var barf = this.bar; barf(); // when called here, "this" is the global object // when called from a click, "this" is the html element $("#thing").after($("<div>click me</div>").click(barf)); } foo.prototype.bar = function() { alert(this); } Source: Tips4all

We are using jQuery in our project. We have numerous custom javascript files in our web-app that have UDFs utilizing the jQuery features. We need to reduce the size (as a part of performance improvement activities) and I am looking for a reliable 'minifier' for these files (it would be great if the same tool could minify the CSS files too) We tried JSLint and JSMin - but JSLint does not complete and throws many exceptions as soon as it encounters jQuery code.

I'd like to use JSLint but am wary of tools that have access to my unfiltered source-code. Is there an offline version or is there another similar tool that does " lint error checking" for JavaScript offline?

The "classic" approach to web development has been for some time a thin client and a thick server: the server generates HTML and spits it out for the browser to render only. But with current browsers (and also due to the availability of good libraries and frameworks) Javascript now works. Web devs can now pretty much assume that their Javascript code will work and stop bothering. This certainly opened new possibilities for web development. Apps could now be composed mostly of HTML content returned from the server and rendered by the browser with some UI manipulation being done client-side. The client could even query the server for fresh data for updating parts of the UI. But can we go down all the other way? An app can certainly be designed as a server that spits only the most minimalist JSON glued together to a thick Javascript client responsible for building and controlling the whole user interface. Yeah, this approach can seriously break URLs to the extent that people

I'm attempting to capture mouse events on an element with another absolutely-positioned element on top of it.

I'm about to start on a small, static website project: no database or CMS required. Basically, a brochure website. I used the CodeIgniter framework recently to develop a full-blown web application, and I'm wondering if it appropriate to also use CI for smaller, simpler sites. Typically for a static brochure site I would write regular PHP pages with a few includes thrown in to save on repetition (i.e. HTML with a sprinking of PHP), but this time around I'm wondering if my new friend CodeIgniter might be able to streamline the development process. Is it sensible to consider a framework for such a simple project, or is it overkill? I'm worried that I might be the proverbial carpenter whose only tool is a hammer, and sees every problem as a nail! Source: Tips4all

I think I may have found a bug in PHP's crypt() function under Windows. However : I recognize that it's probably my fault . PHP is used by millions and worked on by thousands; my code is used by tens and worked on by me. (This argument is best explained on Coding Horror .) So I'm asking for help: show me my fault. I've been trying to find it for a few days now, with no luck. The setup I'm using a Windows server installation with Apache 2.2.14 (Win32) and PHP 5.3.2. My development box runs Windows XP Professional; the 'production' server (this is an intranet setup) runs Windows Storage Server 2003. The problem happens on both. I don't see anything in php.ini related to crypt() , but will happily answer questions about my config.

When doing some web maintenance today, I noticed a strange new folder on my GoDaddy hosting account at the root level named "dbboon", with a single file inside, called proxy.php.

There are only a few areas of the site which will require the client to be able to update the content themselves.

There's manage.py runserver in Django or ruby script/server in Ruby on Rails — those familiar with one of those frameworks should already get the idea what I'm looking for. They run tiny "standalone" web server, which is perfectly enough to debug the application locally, without any need for other software (Apache/Nginx/Lighttpd/etc). I wonder is there any PHP implementation of such tool, or, maybe, some PHP framework has such feature? Surely, I can pack pre-built pre-configured static nginx executable, but this would not be pretty, and certainly not cross-platform. Having standalone debug webserver written in PHP itself will make the package self-contained. I.e. I'd like to type something like php tools/runserver.php , point browser to http://localhost:8000/ and see the site up and running, ready to debug. My Google-fu has failed me, but I strongly suspect that there is such project already. Source: Tips4all

I am developing an OpenID consumer in PHP and am using the fantastic LightOpenID library ( http://gitorious.org/lightopenid ). Basing my code off of that found in the example client script I have successfully created a consumer. However, I've run across a snag: Google requires the openid.identity and openid.claimed_id to be set to "http://specs.openid.net/auth/2.0/identifier_select" (see here ). If I do that it works but other providers (i.e. AOL) don't. Here are my questions: Is Google a corner case –– is it the only OpenID provider where identifier_select is required, contrary to the OpenID specs? Is there a shortcoming in the LightOpenID library? Is my understanding of how OpenID works incorrect? If Google is not the only provider that requires identifier_select are there a finite number of them which I'll just hardcode in, or is there someway to determine this through the OpenID spec? I'm new to the internals of OpenID so I wou

I'm working on a completely ajax-driven application where all requests pass through what basically amounts to a main controller which, at its bare bones, looks something like this: if(strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') { fetch($page); } Is this generally sufficient to protect against cross-site request forgeries? It's rather inconvenient to have a rotating token when the entire page isn't refreshed with each request. I suppose I could pass and update unique token as a global javascript variable with every request -- but somehow that feels clumsy and seems inherently unsafe anyway. EDIT - Perhaps a static token, like the user's UUID, would be better than nothing? EDIT #2 - As The Rook pointed out, this might be a hair-splitting question. I've read speculation both ways and heard distant whispers about older versions of flash being exploitable for this kind of shenanigans. Since I know nothing about that

I'm using a third party storage system that only returns me stdClass objects no matter what I feed in for some obscure reason. So I'm curious to know if there is a way to cast/convert an stdClass object into a full fledged object of a given type. For instance something along the lines of: //$std_class is an stdClass instance $converted = (BusinessClass) $stdClass; I am just casting the stdClass into an array and feed it to the BusinessClass constructor, but maybe there is a way to restore the initial class that I am not aware of. Note: I am not interested in 'Change your storage system' type of answers since it is not the point of interest. Please consider it more an academic question on the language capacities.

First question Please, could you explain me how simpliest ACL could be implemented in MVC. Here is the first approach of using Acl in Controller... <?php class MyController extends Controller { public function myMethod() { //It is just abstract code $acl = new Acl(); $acl->setController('MyController'); $acl->setMethod('myMethod'); $acl->getRole(); if (!$acl->allowed()) die("You're not allowed to do it!"); ... } } ?> It is very bad approach, and it's minus is that we have to add Acl piece of code into each controller's method, but we don't need any additional dependencies! Next approach is to make all controller's methods private and add ACL code into controller's __call method. <?php class MyController extends Controller { private function myMethod() { ... } public function __call($name, $params) { //It is just abstract code $acl = new Acl();

I'm a big fan of PHP and it's obviously a very weakly-typed language. I realize some of the benefits include the general independence of changing variable types on the fly and such. What I'm wondering about are the drawbacks. What can you get out of a strongly-typed language like C that you otherwise can't get from a weakly-typed one like PHP? Also with type setting (like double($variable)), one could argue that even a weakly-typed language can act just like a strongly-typed one. So. Weak-type. What are some benefits I didn't include? More importantly, what are the drawbacks? Source: Tips4all
