I follow this documentation: http://symfony.com/doc/current/cookbook/form/form_collections.html.
So, tags displayed as group of textareas, but i need display tags as HTML 'select' element with 'multiple' attribute for saving 'Task'-object including selected 'Tags' later.
Maybe, symfony have a 'black magic' converter from 'tags' entity to form and vice versa. I don't know. But, maybe, i found a wrong way for doing that. Somebody help me please.
If you followed the tutorial, you just need to change your
buildForm method on the
TagType class, so that the
name field becomes a
choice type instead of a (guessed)
$builder->add('name', 'choice', array( 'choices' => array( 'valueA' => 'labelA', 'valueB' => 'labelB', 'valueC' => 'labelC', 'valueD' => 'labelD', // ... ), 'multiple' => true, );
And if your choice list is dynamic, a good practice is to declare your form type as a service.
Some more info about the
choice field type are documented here.
