以一种形式传递两个实体

Question

I have a little question: When I want to build Forms with the createForm() function. How I can add a second entity to this?

Here is my example code.

public function newAction()
{
    $entity = new Event();
    $picture = new Picture();

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

    return array(
        'entity' => $entity,
        'form'   => $form->createView(),
    );
});

I tried the add function on $form , but it doesn't work. Now I will add the Entity Fields from Picture to the form I created before. Thank for your help.

Answer 1

The correct way to handle your situtation whould be using subforms / field-types.

Create a form EventPictureType and add EventType and PictureType to it.

See the cookbook chapter Embedded Forms & How to Create a Custom Form Field Type .
