Php header('Location") error
- by Umeed
I'm having some difficulty with my php coding.
I have 3 files, add.php, lib.php, and view.php
I created a simple form, and when the user clicks submit, it should direct them to the view.php where it will display the database. Now I'm having a couple issues I can't seem to resolve.
when the user clicks submit and the fields are blank or there is an error no entry should be made into the view page (or database)...however when I click submit a blank entry is made into the database. ALSO if i click "enter product" from the top menu bar anytime I click it, it causes a blank entry into the database. I can't figure out why that's happening.
My next issue is with the header('Location')
and my browser says:
"Warning: Cannot modify header information - headers already sent by (output started at lib.php:13) in add.php on line 16"
However if I click submit on my form it goes away.
Here is the code for the pages:

I truly apologize if the code is really messy.
Any help / advice / solution is greatly appreciated thank you.
And yes this was an assignment---it was due last week but since I couldn't finish it, it's not worth any marks anymore.
