Question

In Symfony2 TWIG, when trying to generate a path like this:

<a href="{{ path('folder_new', { 'folder': folder.id }) }}">

I don’t get the route I expected

Here is what I expected:

http://localhost/site/web/app_dev.php/Media/folder/new/2

here is what I in fact got from the path() command

http://localhost/site/web/app_dev.php/Media/folder/new?folder=2

Why do I get it formatted as a standard querystring (get) variable instead of a route?

Answer 1

The reason is that I named the variable wrong.

folder_new:
    pattern:  /new/{parent}
    defaults: { _controller: "AcmeBundle:Folder:new", parent : NULL }

In my routing I had called the variable parent and not folder.

Correct path() should have been like this:

<a href="{{ path('folder_new', { 'parent': folder.id }) }}">

So, I learned that when Symfony2 can’t find a route parameter matching the variable passed to the path() function, it appends the variable in standard querystring ($__GET) format instead of generating an error message.

Would have found it quicker if there were an error message, but I see the use of having it the way it is.

Cheers! =)
