Lock Record when other user edit

[raimis]

Can fabrik this ? :/

 

[startpoint]

Make field lock, field logged_user_id, edited_by.
When open form for edit with php plugin set lock = '1' or 'lock' or whatever, user_id ->logged user_id, edited_by -> logged user_id again.
Use list plugin caneditrow and set to edit record only when edited_by= logged_user_id and lock == 1.
