When trying to submit new Active record instance and save it to database table (by clicking the create button in action CREATE on screen), I got direct PHP error message. You could see 2 images below (you could ignore the logic, I just focus on why this PHP error was being displayed):
I can’t explain why this direct PHP ERROR is thrown. Because, my understanding is, after I click create button, Yii will validate all this AR class property. If this validation failed, I simply get a Validation error (either Ajax client or server validation checking) not direct PHP error message as it has happend here.
Could someone tell me what wrong in this situation?
