I have a survey form which contains lots of input fields. When I try to fill all the input fields it saves to the database. But when I only fill a few of the input fields and leave other fields blank it does not save and it shows error like these.
Notice: Undefined index: scale_fun in C:\xampp\htdocs\survey1\includes\save2.php on line 22
Notice: Undefined index: job_performance in C:\xampp\htdocs\survey1\includes\save2.php on line 24
what should I do to remove these errors?
