function field_attach_submit

Perform necessary operations on field data submitted by a form.

Currently, this accounts for drag-and-drop reordering of field values, and filtering of empty values.

Parameters

$entity_type: The type of $entity; e.g. 'node' or 'user'.

$entity: The entity being submitted. The 'bundle', 'id' and (if applicable) 'revision' keys should be present. The actual field values will be read from $form_state['values'].

$form: The form structure where field elements are attached to. This might be a full form structure, or a sub-element of a larger form.

$form_state: An associative array containing the current state of the form.

array $options: An associative array of additional options. See _field_invoke() for details.
