php - Symfony: Handling slashes on URL parameters -

i'm running issues trying guess how handle urls parameters on symfony+twig.

i have route:

<route id="artist.front" path="/artist/{kw}/"> <default key="_controller">app\web\controllers\front::homepage</default> </route> 

and code on twig template:

{% autoescape false %} <a href="{{ path('artist.front',{'kw':a.urlkeyword|url_encode} )}}">{{ a.name }}</a> {% endautoescape %} 

urlkeyword parameter passed (i.e. not url encoded previously) both on entity constructor , on getter (geturlkeyword).

however, when rendering template html code:

<a href="/index.php/artist/ac%252fdc/">ac/dc</a> 

(if remove url_encode template twig throws error calling path()).

the target controller has code:

public function artistpage($kw) {     $decoded = urldecode($kw);     $this->log->info("kw:      {$kw}");     $this->log->info("decoded: {$decoded}"); } 

and echoes:

kw:      ac%2fdc  decoded: ac/dc  

so think kw read correctly controller, understand url should encoded ac%2fdc instead on final html code on first place: urlencoded string encoded twice.

is ac%2fdc correct encoding, or necessary use double encoding (ac%252fdc) in symfony? and, if possible use first (correct) url encoding, doing wrong?

try:

<route id="artist.front" path="/artist/{kw}/">     <default key="_controller">app\web\controllers\front::homepage</default>     <requirement key="kw">.+</requirement> </route> 

and remove url encoding/decoding.
