Validation for set_relation_n_n field.

26 February 2013 - 12:59 PM



I have the following section in my db.




I'm using set_relation_n_n to allow the content manager to select questions for the quiz. Fairly straightforward.


But in my case, quizzes should have 7 questions — no more, no less. Is there any way to set this validation?


Here's how I'm setting the relation:

$form1->set_relation_n_n('Questions', 'quiz_has_questions', 'quiz_questions', 'quiz_id', 'question_id', 'text', 'quiz_order'); 


I tried setting a rule like this, but it's not doing anything. Should it? If not, is there any workaround?

$form1->set_rules('Questions', 'Questions', 'callback_questions_check');
