CakePHP 2.x Reverse Routing Link Helper - cakephp

Question

In my CakePHP App I connected the following Route:
Router::connect('/:city/dealer/:id',
array('controller' => 'dealers', 'action' => 'view'),
array(
'pass' => array('city', 'id'),
'city' => '[a-z]+',
'id' => '[0-9]+'
)
);
This works great and enables: domain.com/washington/dealer/1
But how do I generate the proper HTML link in the View for this URL? If I just do this:
echo $this->Html->link(
'Testlink',
array('washington', 'controller' => 'dealers', 'action' => 'view', 1)
);
It adds all the params to the end of the generated link:
http://domain.com/dealers/view/washington/1
How do I do this properly?

Answer 1

I believe you still need to specify the params, like so:
echo $this->Html->link('Testlink',
array('controller' => 'dealers', 'action' => 'view', 'city' => 'washington',
'id'=> 1));
Cake has a similiar example in the cookbook:
<?php
// SomeController.php
public function view($articleId = null, $slug = null) {
// some code here...
}
// routes.php
Router::connect(
'/blog/:id-:slug', // E.g. /blog/3-CakePHP_Rocks
array('controller' => 'blog', 'action' => 'view'),
array(
// order matters since this will simply map ":id" to $articleId in your action
'pass' => array('id', 'slug'),
'id' => '[0-9]+'
)
);
// view.ctp
// this will return a link to /blog/3-CakePHP_Rocks
<?php
echo $this->Html->link('CakePHP Rocks', array(
'controller' => 'blog',
'action' => 'view',
'id' => 3,
'slug' => 'CakePHP_Rocks'
));

Hi Sebastian its probably too late to help you, but I may be able to help someone else with this problem. The key to solving your problem is adding to the url method in Helper class. I did this by creating a AppHelper.php in my View/Helper. It looks like this. I changed out my parameter for yours city.
View/Helper/AppHelper.php
<?php
App::uses('Helper', 'View');
class AppHelper extends Helper {
function url($url = null, $full = false) {
if (is_array($url)) {
if (empty($url['city']) && isset($this->params['city'])) {
$url['city'] = $this->params['city'];
}
if (empty($url['controller']) && isset($this->params['controller'])) {
$url['controller'] = $this->params['controller'];
}
if (empty($url['action']) && isset($this->params['action'])) {
$url['action'] = $this->params['action'];
}
}
return parent::url($url, $full);
}
}
?>
Then I create routes like
Router::connect('/:city/dealer/:id',
array('controller' => 'dealers', 'action' => 'view', 'id'=>':id'),
array('pass' => array('city', 'id'),
'city' => '[a-z]+',
'id' => '[0-9]+'
));
Hope this helps :)
