Modified , I have attached link to the program codes to this post - Google drive , nairaland didn't allow txt file containing SQL query. l

I have an issue that I can't seem to find solution to for 3 days now.

Please help!

Overview : This a product rating / review system for a test website.

In the first screenshot below, the query on line 54 runs well.

In the second screenshot, I tried to get a value from a form in the previous page as use it as a variable in the query, then the query will not work.

The third screenshot, I realized that the if I put the codes such as below anywhere in the code, then the query won't work(including line 54 that was working before, and it doesn't return any error.

$work_id = $_POST['work_id'];

Are you sure there is anything as 'work_id' in the $_POST request?, Also check the form action
