input fields shows errors when left empty

Question

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?

Check if variables are set before you use them – brombeer Sep 13 '22 at 16:28 — brombeer, Sep 13 '22 at 16:28

try to make validation in the front (before submitting the form) or backend ( after submitting the form ) OR You can set columns to accept Null from the database.

check this too : "Notice: Undefined variable", "Notice: Undefined index", "Warning: Undefined array key", and "Notice: Undefined offset" using PHP

Never rely on front-end validation alone (can be tampered with), always use backend validation – brombeer Sep 14 '22 at 05:55
