Overwrite parameters in beforeMatch

You have two options:

1. You can create functionality like this using dispatcher, check docs here: https://docs.phalcon.io/pl/latest/reference/dispatching.html
2. Make some kind of wildcard route that match all cases that you need (ex. "/[0-9a-z-_\/]"). You catch this url in specific action that will run searching in database and then redirect to specific page.

Thanks for your reply.

1. I tried it, but the status code for the new page is always 404.
2. I tried already and like I said in my original post, $router->getControllerName() and $router->getActionName() doesn't get overwritten.

Ad 1. - Without example of your code it will be hard to check what is wrong. My guess: use beforeDispatch event instead event that you are using right now. Add plugin to this event that will search for match. Ad 2. - I pointed on "redirect" not "forward" - they are different.

I managed to get where I wanted by using beforeMatch.

$router->add('/(?P<link_rewrite>[A-Za-z0-9\-]+)(?:\.(?P<attribute>[A-Za-z\-]+)\-(?P<id_attribute>[0-9]+)?)?(?:\.html?)?')
            ->beforeMatch(function($uri, $route) {
                if (preg_match($route->getCompiledPattern(), $uri, $matches))
                {
                    // here goes some db query-ing to extract id_product based on link_rewrite...
                    $route->reConfigure($route->getPattern(), array(
                        'controller'    => 'product',
                        'action'        => 'index',
                        'id_product'    => (int) $id_product_from_db,
                        'link_rewrite'  => isset($matches['link_rewrite']) ? $matches['link_rewrite'] : '',
                        'id_attribute'  => isset($matches['id_attribute']) ? $matches['id_attribute'] : '',
                    ));
                    return true;
                }
                return false;
            }
        );

Are there any ways to send a literal integer?

'cause if I send $id_product_from_db = 1, then $this->dispatcher->getParam('id_product') is set to {link_rewrite}'s value.

There is a way to send a literal integer 1 or boolean without being overwriten?

What do you mean? This is not the issue of type that you are sending. Your link_rewrite just match integers too.

This is my code:

$router->add('/{slug:(?P<slug>[a-z0-9\-]+)}', [
            'controller'    => 'category',
            'action'        => 'index'
        ])->beforeMatch(function($uri, $route) use ($di) {
            if (preg_match($route->getCompiledPattern(), $uri, $match))
            {
                $result = Category::findFirstBySlug($match['slug']);
                if ($result)
                {
                    $params = [
                        'id_category' => $result->id_category,
                        'true' => true,
                    ];
                    $route->reConfigure($route->getPattern(), array_merge($route->getPaths(), $params));
                    return true;
                }
            }
        })->setName('category');

Actual $this->dispatcher->getParams():

Array
(
    [slug] => women
    [id_category] => women
    [true] => women
)

Expected $this->dispatcher->getParams():

Array
(
    [slug] => women
    [id_category] => 1
    [true] => 1
)

Ah now I see where is the problem :)

The effect of this:
array_merge($route->getPaths(), $params)

looks like:

   array(
            'controller' => 'category',
            'action' => 'index',
            'slug' => 1,
            'id_category' => 1,
            'true' => true
        );

So you are reconfiguring your router to use your first matched value (that means this "1" or "true") as each param. Test the reconfiguration of your route as follow:

             $route->reConfigure($route->getPattern(), array_merge($route->getPaths(), ['customParams' => $params]));

Nice one! But it comes with a warning:

Warning: Illegal offset type in /home/www/index.php on line 376 

index.php line 376

echo $application->handle()->getContent();

Will do. Thanks! :)
