Multiple forms of same type - Symfony 2

Question

So I have my controller action similar to this

$task1 = new Task();
$form1 = $this->createForm(new MyForm(), $task1);

$task2 = new Task();
$form2 = $this->createForm(new MyForm(), $task2);

And let's say my MyForm has two fields

//...
$builder->add('name', 'text');
$builder->add('note', 'text');
//...

It seems like since the two forms are of the same type MyForm, when rendered in the views, their fields have the same name and IDs (the 'name' fields of two forms share the same name and id; the same goes for the 'note' fields), because of which Symfony may not bind the forms' data correctly. Does anyone know any solution to this?

Answer 1

// your form type
class myType extends AbstractType
{
   private $name = 'default_name';
   ...
   //builder and so on
   ...
   public function getName(){
       return $this->name;
   }

   public function setName($name){
       $this->name = $name;
   }

   // or alternativ you can set it via constructor (warning this is only a guess)

  public function __constructor($formname)
  {
      $this->name = $formname;
      parent::__construct();
  }

}

// you controller

$entity  = new Entity();
$request = $this->getRequest();

$formType = new myType(); 
$formType->setName('foobar');
// or new myType('foobar'); if you set it in the constructor

$form    = $this->createForm($formtype, $entity);

now you should be able to set a different id for each instance of the form you crate.. this should result in <input type="text" id="foobar_field_0" name="foobar[field]" required="required> and so on.
