Item Metadata
Item Metadata Repository
if ( $item_metadata->get_field()->get_parent() > 0 && is_null($item_metadata->get_meta_id()) )
When we are adding a field that is child of another, this means it is inside a compound field
In that case, if the Item_Metadata object is not set with a meta_id, it means we want to create a new one and not update an existing. This is the case of a multiple compound field.
public function delete($item_metadata)
Returns: mixed|void
