How to get params in action in ZendFramework 2? - php

Question

I have configured a route in my module.config.php to handle two parameters ,
here is the content of the file module.config.php , i put just the definition of the routes ( same routes ) :
updated :
'router' => array(
'routes' => array(
'Products' => array(
'type' => 'Zend\Mvc\Router\Http\Literal',
'options' => array(
'route' => '/application/admin/products[/:id]',
'defaults' => array(
'__NAMESPACE__' => 'Application\Controller',
'controller' => 'Admin',
'action' => 'index',
),
),
),
'productsList' => array(
'type' => 'segment',
'options' => array(
'route' => '/application/products/productsList[/:type][/:id]',
'defaults' => array(
'__NAMESPACE__' => 'Application\Controller',
'controller' => 'Products',
'action' => 'productsList'
),
),
),
'Emplacement' => array(
'type' => 'segment',
'options' => array(
'route' => '/application/support/listeEmplacementsSupport[/:pkSupport]',
'defaults' => array(
'__NAMESPACE__' => 'Application\Controller',
'controller' => 'Support',
'action' => 'listeEmplacementsSupport',
),
),
),
'application' => array(
'type' => 'Literal',
'options' => array(
'route' => '/application',
'defaults' => array(
'__NAMESPACE__' => 'Application\Controller',
'controller' => 'Index',
'action' => 'index',
),
),
'may_terminate' => true,
'child_routes' => array(
'default' => array(
'type' => 'Segment',
'options' => array(
'route' => '/[:controller[/:action[/:id][/:dr]]]',
'constraints' => array(
'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
),
'defaults' => array(
),
),
),
),
),
),
),
And I build a link in the view using the following
<a href="/application/products/productsList/mandan/<?php echo $coreg['idProduct']; ?>" >
<img height='20' src="/img/mail-recevoir-32.png" alt='products' />
</a>
To get one parameter I use
$param = $this->params('id');

Answer 1

Routes are matched in the 'Last in first out' LIFO order.
The relevant section of the documentation states:
Typically, routes should be queried in a LIFO order, and hence the reason behind the name RouteStack. [...] you will need to ensure that routes that potentially overlap are registered such that the most specific match will match first (i.e., register later)
Therefore based on you current configuration, as all the routes are register at the top level, the last route (application/default) is being checked and then subsequently matched first, before the productList is given a chance.
Also because application/default defines an optional id parameter as the first argument this is the reason that you get the value of the type param when using $this->params('id').
Soultion
The easiest solution is just to reorder the routes; moving the application route right to the top of the definition should work.
The order should be the following
'router' => array(
'routes' => array(
'application' => array(
// .. same
'child_routes' => array(
'default' => array(
// .. Same
),
),
),
'Products' => array(
// ..same
),
'productsList' => array(
// ..same
),
'Emplacement' => array(
// ..config
),
),
),
You could alternatively give each route a priority, regardless of the order, however I think It would make more sense to keep them in a natural order to save confusion in the future.
While I'm here
I mentioned in my comment you incorrectly used a Literal route rather than a Segment. You have this same issue with the the Products route definition. If a route is literal it will only match on the exact value (so you would need /[:id] in the URL).
/application/admin/products[/:id]
Therefore you will also need to update this route to a segment in order for the product id to be regarded as a parameter.
Lastly, there is a easier way of constructing URL's in the view, using the URL view helper. Your view script code would be changed to
<?php
$type = 'mandan';
$id = $coreg['idProduct'];
?>
<a href="<?php echo $this->url('productsList', compact('type', 'id')); ?>">
<img height='20' src="/img/mail-recevoir-32.png" alt='products' />
</a>
