Before_Filter With Parameters

before_filter with parameters

I'd do it like this:

before_filter { |c| c.authenticate_rights correct_id_here }

def authenticate_rights(project_id)
  project = Project.find(project_id)
  redirect_to signin_path unless project.hidden
end

Where correct_id_here is the relevant id to access a Project.

Laravel 4 Call filter in controller with parameters

You can pass a parameter as a string after your filter name. Use : to separate method name and parameter.

public function __construct()
{
    $this->beforeFilter('filterSomething:param');
}

If you have many parameters, you can use , to separate your parameters.

$this->beforeFilter('filterSomething:param1,param2');

And then define your filter logic in app/filters.php. Don't forget to add parameter in your filter method for passed parameters.

Route::filter('filterSomething', function($route, $request, $param1, $param2)
{
    // Do something with your params.
});

beforeFilter() not being called?

I forgot to call the base class' beforeFilter() since I was overloading it in my ImagesController

class ImagesController extends AppController {

    var $name = 'Images';
    var $helpers = array('TinyMCE');

    function beforeFilter(){
        parent::beforeFilter(); // <-- here
        if(!isset($this->params['admin'])) {
            $this->Session->setFlash(__('Access denied.', true));
            $this->redirect(array('controller'=>'users','action'=>'login','admin'=>false));
            exit();
        }    
    }

    function index() {
        $this->Image->recursive = 1;
        $this->set('images', $this->paginate());
    }

}

laravel 4 where the beforefilter's second parameter pass to?

You are looking at the wrong place. That array parameter is not being passed to the auth filter. It's a parameter for Controller.beforeFilter().

As you can see in Laravel's documentation, beforeFilter() expects two parameters:

$filter The filter to be executed before your controller actions. These filters are the ones that you see in filters.php file.
$options An array with options for the filter being passed. In this case, you are passing the except option with a value of getLogin.

/**
* Register a new "before" filter on the controller.
*
* @param  string  $filter
* @param  array   $options
* @return void
*/
public function beforeFilter($filter, array $options = array())
{
    $options = $this->prepareFilter($filter, $options);

    $this->filters[] = new Before($options);
}

cakephp $this- params not set in beforeFilter

My bad, I had overriden beforeFilter in an controller and forgot to call parent::beforeFilter() at the start. Now it's ok.

Laravel Before Filter in the Controller with arguments

I can confirm what happens... when you add a filter to a controller, any arguments passed to the action are added to the front of the filter's arguments. You can use func_get_args() to confirm that this is the case.

However, when you add a filter to a route this is not the case, the filter is run without any additional arguments.

So I can see 2 choices here, either add the filter to the route...

Route::get('test/(:any)', array('before' => 'permission:destroy|auth', 'use' => 'test@show'));

Or modify your filter to use func_get_args(), like...

Route::filter('permission', function()
{
    $args = func_get_args();
    $permission = array_pop($args);

});
