Question

i created a customFormtype in symfony2 and i’m using it in a formbuilder in my controller.
This is the html result when i render the form:

        <div id="form">
              <input type="hidden" id="form__token" name="form[_token]" value="2e8fe0d777b5c0d7d30d9bfd9d5143811c790b1d">
              <div>
                 <label class=" required">Stars</label>
                 <!-- some other stuff -->
              </div>
        </div>

Where does the id form came from and where can i change the name?
Thank you very much.

Answer 1

The id of the form is defined by the getName() function

class TaskType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('task');
        $builder->add('dueDate', null, array('widget' => 'single_text'));
    }

    public function getName()
    {
        return 'task';
    }
}

Ex. ‘task’ here. (http://symfony.com/doc/current/book/forms.html#creating-form-classes)
