I have two actions for a single route but I don't know how to build the URL

  • 772

I have a problem that I have not been able to solve, I have a route with a child, like this:

'apps' => array(
    'type'          => 'Segment',
    'options'       => array(
        'route'       => '/apps[/[:action[/:id]]]',
        'constraints' => array(
            'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
        ),
        'defaults'    => array(
            'controller' => 'Apps\Controller\Index',
            'action'     => 'index'
        ),
    ),
    'may_terminate' => true,
    'child_routes'  => array(
        'ximages' => array(
            'type'    => 'Segment',
            'options' => array(
                'route'       => '/ximages[/[:action[/:id_ximage]]]',
                'constraints' => array(
                    'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
                    'action'     => '[a-zA-Z][a-zA-Z0-9_-]*',
                ),
                'defaults'    => array(
                    'controller' => 'Apps\Controller\xImages',
                    'action'     => 'index'
                )
            ),
        ),
    ),
),

Now in the file .phtmlI want to access the path http://miserver/apps/view/1/ximages/images/1and what I do is the following:

echo $this->url('apps/ximages', array(
        'action'    => 'view',
        'id'        => 1,
        'id_ximage' => 2
    ));

But that code only prints the route http://miserver/apps/view/1/ximages/index/1and I don't know how the name actionof the child route can be passed to it.

    In theory, the array that you are going to pass to $this->url(...)should not have two keyequal ones, I think that could cause errors when mounting the url, and even more so when it comes to the part that resolves controllerand action, which should not produce ambiguities.

    The route you are mounting should have all these parameters:

    echo $this->url('apps/ximages', array(
    'action'    => 'view', // <-- parent
    'id'        => 1, 
    'action'    => 'images', // <-- child
    'id_ximage' => 2
));

    Which should not be possible due to the aforementioned. Not being able to resolve the second action, it takes the one with the default routewhich is the index.

    Something that occurs to me would be to pass the parameters of the parent route to the child route by modifying the route.

    'child_routes' => array(
    'ximages' => array(
        'type'    => 'Segment',
        'options' => array(
            'route'       => '/:parent_action/:parent_id/ximages[/[:action[/:id_ximage]]]',
            'constraints' => array(
                'parent_action' => '[a-zA-Z][a-zA-Z0-9_-]+',
                'parent_id'     => '[0-9]+',
                'action'        => '[a-zA-Z][a-zA-Z0-9_-]*',
                'id_ximage'     => '[0-9]*',
            ),
            'defaults'    => array(
                'controller' => 'Apps\Controller\xImages',
                'action'     => 'index'
            )
        ),
    ),
)

    Calling it like this:

    echo $this->url('apps/ximages', array(
    'parent_action' => 'view',
    'parent_id'     => 1,
    'action'        => 'images',
    'id_ximage'     => 2
));

    Again, in theory, having the parent 's actione -parameters set to may or may not be present in the , should resolve to the path you're looking for.idrouteurl

    I haven't tested it, but because of how zf2 resolves paths it should be an alternative to your question.

    If not, and when mounting the url it asks you that the parameters of the parent route are missing, you should change the route construction approach and mount the classic one.'route' => ':controller/:action/:id1/:id2/...'

    It depends on how the routes are planned, they can be one more element to work with, or they can cause you real headaches.

    EDIT

    I have set up a test module and the problem is what it was saying from the beginning. Two equal keys in el routegenerates problems, since it resolves actiondel first route appsand defaults to actiondel route apps/ximages.

    actionWith the approach that I carry out, despite being optional parameters, the e parameters must necessarily be passed idif they are variables and a default value is not passed.

    So if you want to maintain this strategy routes, with variable parameters, (especially the action), you would have to find a way to inject the parameters of the route appsand then mount the ViewHelper $this->url(...). Solution that is going to be more tedious to build and maintain, and I don't know if it would work correctly.

    In particular, I would solve it by putting the routeparallel to appsinstead of as a child.

    'apps'    => array(
    'type'    => 'Zend\Mvc\Router\Http\Segment',
    'options' => array(
        'route'       => '/apps[/[:action[/:id[/]]]]',
        'constraints' => array(
            'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
            'id'     => '[0-9]*',
        ),
        'defaults'    => array(
            'controller' => 'Application\Controller\Index',
            'action'     => 'index',
        ),
    ),
),

'ximages' => array(
    'type'    => 'Zend\Mvc\Router\Http\Segment',
    'options' => array(
        'route'       => '/apps/:parent_action/:parent_id/ximages[/[:action[/:id_ximage[/]]]]',
        'constraints' => array(
            'parent_action' => '[a-zA-Z][a-zA-Z0-9_-]+',
            'parent_id'     => '[0-9]+',
            'action'        => '[a-zA-Z][a-zA-Z0-9_-]*',
            'id_ximage'     => '[0-9]*',
        ),
        'defaults'    => array(
            'controller' => 'Application\Controller\Other',
            'action'     => 'index'
        )
    ),
),

    and ride theViewHelper

    $this->url('ximages', array(
    'parent_action' => 'view',
    'parent_id'     => 2,
    'action'        => 'images',
    'id_ximage'     => 9,
));
