    <p>This question started out with me not understanding why I couldn't pass variables to a symfony2 global helper function (service), but thanks to people brighter than I, I realized my error was about trying to use the security_context from within a class that didn't have it injected so...</p> <p>This is the final result, the code that works. I found no better way of making this helpful to the comunity.</p> <p>This is how you can get the user and other data from security_context from within a global function or helper function in symfony2.</p> <p>I have the following class and function:</p> <pre><code>&lt;?php namespace BizTV\CommonBundle\Helper; use Symfony\Component\DependencyInjection\ContainerInterface as Container; class globalHelper { private $container; public function __construct(Container $container) { $this-&gt;container = $container; } //This is a helper function that checks the permission on a single container public function hasAccess($container) { $user = $this-&gt;container-&gt;get('security.context')-&gt;getToken()-&gt;getUser(); //do my stuff } } </code></pre> <p>...defined as a service (in app/config/config.yml) like this...</p> <pre><code>#Registering my global helper functions services: biztv.helper.globalHelper: class: BizTV\CommonBundle\Helper\globalHelper arguments: ['@service_container'] </code></pre> <p>Now, in my controller I call on this function like this...</p> <pre><code>public function createAction($id) { //do some stuff, transform $id into $entity of my type... //Check if that container is within the company, and if user has access to it. $helper = $this-&gt;get('biztv.helper.globalHelper'); $access = $helper-&gt;hasAccess($entity); </code></pre>

    1. COYou are definitley able to to pass variables from your controller to your service if you need to. You also have the option of passing stuff into the service (Dependency Injection) in your config.yml. What is it your trying to get at? In the __construct it was $container but in the hasAccess it was $entity.

    2. COIn the controller, the variable is called $entity, once it gets to the service function I like to call it $container, there is no connection between the names of the arguments as far as I understand, php knows them only by argument1, argument2 etc. passed into the function? Not sure I understand your question "what am I getting at?"

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
