I'm trying to create entities from my custom form. To do that, I created "Add more" button, where I'm dynamically adding new elements that I'm attaching fields to by using:
field_attach_form('myentity', $entity, $form['wrapper']['myentities'][$key]['fields'], $form_state);
I would like to create entities in submit callback with field values from those elements.
The problem is, that when I have a multiple elements, inputs for the same type of fields of different entities have the same "name" attribute (eg.
field_myfield[und][value]), which means that I can access only the value from the field of the last entity in the submit callback, which means that I cannot fill my entity with proper values before saving. I tried to put '#tree' => TRUE up the form tree, and unset this value on field level, but it didn't change an input name, and "values" structure.
How can I have in my submit callback access to all of the field values, so I could use them for creating entities?
