Hi am Newbie when it comes to PHP and MySQL. Over the past week weeks I have been overwhelmed with PHP, MySQL and WampSERVER. Initially the script was working for about 20 columns when I was adding new columns to my database using PHP it lost connection with MySQL. I started from scratch but its not helping. I get no errors and I don't know what I am doing wrong. If anyone can help I would appreciate it very much. If I insert data manually through MySQL it works fine. Any advise is helpful.
