FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

UjsBundle for Symfony 2
An unobtrusive JavaScript bundle for Symfony 2. Allows for using non-GET routes with simple links.
Dependencies
- Symfony
- jQuery
Installation
Install just like any other Symfony bundle. See the section below on security for further instructions.
After installing, you will need to run app/console assets:install or add
@UjsBundle/Resources/public/js/ujs.js if you are using Assetic.
Usage
For any link that you would like to submit with an HTTP method other than GET,
just include a data-method attribute, like so:
<a href="/posts/15" data-method="DELETE">Delete this post</a>You may optionally include a data-confirm attribute, which will be used as
the text in the JavaScript confirm dialog.
<a href="/posts/15" data-method="DELETE" data-confirm="Are you sure you
want to delete this post?">Delete this post</a>If you set the data-confirm attribute to false, no confirmation message
will be presented. Be careful with this, though, since browsers that do link
prefetching may follow the link and perform destructive actions.
Security
Important!! If you do not implement these steps, your app will be vulnerable to cross-site scripting attacks!
First, you will need to include an HTML <meta> tag on any page that yo would
like to use UJS. For example, add the following to your <head> section:
<meta name="_ujs_csrf_token" content="{{ csrf_token('ujs') }}" />
<meta name="_ujs_csrf_token_name" content="_ujs_csrf_token" />Any controller action that you would like to submit with UJS should check the CSRF token to make sure it is valid, like so:
public function deleteAction(Request $request)
{
if ($request->request->has('_ujs_csrf_token') && $this->get('form.csrf_provider')->isCsrfTokenValid('ujs', $request->request->get('_ujs_csrf_token'))) {
// Do your deleting, posting, etc.
}
}
