Get all parameters after action in Zend?

Question

When I call a router like below in Zend:

coupon/index/search/cat/1/page/1/x/111/y/222

And inside the controller when I get $this->_params, I get an array:

array(
    'module' => 'coupon',
    'controller' => 'index',
    'action' => 'search',
    'cat' => '1',
    'page' => '1',
    'x' => '111',
    'y' => '222'
)

But I want to get only:

array(
    'cat' => '1',
    'page' => '1',
    'x' => '111',
    'y' => '222'
)

Could you please tell me a way to get the all the params just after the action?

Answer 1

IMHO this is more elegant and includes changes in action, controller and method keys.

$request = $this->getRequest();
$diffArray = array(
    $request->getActionKey(),
    $request->getControllerKey(),
    $request->getModuleKey()
);
$params = array_diff_key(
    $request->getUserParams(),
    array_flip($diffArray)
);

As far as I know, you will always get the controller, action and module in the params list as it is part of the default. You could do something like this to remove the three from the array you get:

    $url_params = $this->getRequest()->getUserParams();
    if(isset($url_params['controller']))
        unset($url_params['controller']);
    if(isset($url_params['action']))
        unset($url_params['action']);
    if (isset($url_params['module']))
        unset($url_params['module']);

Alternatively as you don't want to be doing that every time you need the list, create a helper to do it for you, something like this:

class Helper_Myparams extends Zend_Controller_Action_Helper_Abstract
{
    public $params;

    public function __construct()
    {
        $request = Zend_Controller_Front::getInstance()->getRequest();
        $this->params = $request->getParams();
    }

    public function myparams()
    {       
        if(isset($this->params['controller']))
            unset($this->params['controller']);
        if(isset($this->params['action']))
            unset($this->params['action']);
        if (isset($this->params['module']))
            unset($this->params['module']);
        return $this->params;
    }

    public function direct()
    {
        return $this->myparams();
    }
}

And you can simply call this from your controller to get the list:

$this->_helper->myparams();

So for example using the url:

http://127.0.0.1/testing/urls/cat/1/page/1/x/111/y/222

And the code:

echo "<pre>";
print_r($this->_helper->myparams());
echo "</pre>";

I get the following array printed:

Array
(
    [cat] => 1
    [page] => 1
    [x] => 111
    [y] => 222
)

How about this?

In controller:

$params = $this->getRequest()->getParams();
unset($params['module'];
unset($params['controller'];
unset($params['action'];

Pretty clunky; might need some isset() checks to avoid warnings; could jam this segment into its own method or helper. But it would do the job, right?
