Best way to keep params in the uri for zf2

Question

So a user is directed to a page in my ZF2 app as follows:

http://example.com/some/route/variable?auth=1234&channel=1234&tz=1234&locale=&client=1234

The controller loads a form:

if ($prg instanceof Response) {
    return $prg
} elseif ($prg === false) {

    return new ViewModel([
        'form' => $this->transferForm,
    ]);
}

And in the view:

$form = $this->form;
$form->setAttribute('action', $this->url('some/route',[],true));
$form->setAttribute('method', 'post');

What I want to happen is when the user invokes the form that it posts to the same inbound route, namely:

http://example.com/some/route/variable?auth=1234&channel=1234&tz=1234&locale=&client=1234

Is there a stupidly simple way of doing this?

Or do I need to get each param, and explicityly place them in the form target uri?:

$form->setAttribute('action', $this->url('some/route',[],[query => [''] ]));

As it stands I have written a helper to deal with this:

namespace Some\View\Helper;

use Zend\View\Helper\AbstractHelper;


class ParamsHelper extends AbstractHelper {

    public function __invoke()
    {
        $param1 = (isset($_GET['param1'])) ? $_GET['param1'] : '';
        $param2 = (isset($_GET['param2'])) ? $_GET['param2'] : '';
        $param3 = (isset($_GET['param3'])) ? $_GET['param3'] : '';
        $param4 = (isset($_GET['param4'])) ? $_GET['param4'] : '';
        $param5 = (isset($_GET['param5'])) ? $_GET['param5'] : '';

        $queryParams = (null == $auth) ? [] : ['query' =>
                                                   [
                                                       'param1' => $param1 ,
                                                       'param2' => $param2 ,
                                                       'param3' => $param3 ,
                                                       'param4' => $param4,
                                                       'param5' => $param5
                                                   ]
                                                ];

        return $queryParams;
    }

}

This resolves the issue however it still seems a longwinded and not so dynamic way of resolving the issue...

There is a Url view helper but this helper does (surprisingly) not give you the full request url with query params. But there is also a ServerUrl helper in ZF2 and this one gives you the full url including query params if used like this:

in case of your example:

http://example.com/some/route/variable?auth=1234&channel=1234&tz=1234&locale=&client=1234

It will do the following:

$viewHelperManager = $serviceManager->get('ViewHelperManager');

$urlHelper = $viewHelper->get('url');
$serverUrlHelper = $viewHelper->get('serverUrl');

$urlHelper(); // --> /some/route/variable
$serverUrlHelper(true); // --> http://example.com/some/route/variable?auth=1234&channel=1234&tz=1234&locale=&client=1234

In your view simply as follows:

$this->url(); // --> /some/route/variable

and

$this->serverUrl(); // --> http://example.com/some/route/variable?auth=1234&channel=1234&tz=1234&locale=&client=1234

Note There are actually more people who complain about not being able to reuse query params in the url view helper. On that page there is also a link to an alternative (refactored) Url helper class that does reuse query params.
