i have a problem about get the entity_id in my customfield.module
i know how to get the [width] field value in my program by using the code $item['width'],
but are there any function that i can use to get the entity-id and entity-type='node'?
another question: when i initial a form in my customfield.module,the same problem ,are there
any method that i can use to get the current entity id ?
Thx a lot ~
