Symfony 2 Form collection field with type file

Question

I want to upload multiple files with POST request (without Ajax). Can I use Symfony 2\'s form collection field with type file like this:

Code in Entity:

Answer 1

You need to specify the type of the widget in collection

Look at the: http://symfony.com/doc/2.0/reference/forms/types/collection.html

$builder->add('pictures', 'collection', array(
  // each item in the array will be an "email" field
  'type'   => 'file',
  // these options are passed to each "email" type
  'options'  => array(
    'required'  => false,
  ),
));

For further reading I suggest

http://symfony.com/doc/2.0/reference/forms/types/file.html

Also you need to add sth to this collection to display cuz it will be empty when initialize like in your constructor of entity.
