Question

The user sumbits a form that was build using the symfony 2 framework with abstract type:

<?php
$form = $this->createForm(new MyAbstractType(), new MyEntity());

I receive this post request in an action:

public function receiveFormRequestAction(Request $request){
    //How do I get the abstract type from the request?
}

I need to be able to create the AbstractType used on the form using only information in the request.

1. Is it possible?
2. How do you do it?

Thanks.

Edit:

Sorry if i wasn’t clear enough. in the method “recieveFormRequestAction” i don’t know what abstract type i am going to get, so i cant bind the form directly to MyAbstractType.

This action can, in theory, recieve any AbastractType and bind it.

Answer 1

I ended up doing this:

1. The method getName() on my forms returned exactly the same name as the Form class name

   Class MyAbstractType extends AbstractType
     [...]
     public function getName(){
       return "MyAbstractType";
   }
   

2. Now i can get the type using the hash on the parameter keys

   public function myAction(Request $request){
   $parameterKeys = $request->request->keys();
   $formName = $parameterKeys[0];
   

Ugly as hell, but i needed a quick solution. Until there is a cleaner one, i’m accepting this.
