Just learning: how do I update information in table?
Hi I am just learning to use PHP with MySQL and I am having some difficulties. I have successfully made a php script insert a new row into my table. But how do I have a form only update information in the table without adding a new row?
But what if joe41 wants to change his email address and submits the form with all the other info the same. Instead of adding a new row how does it update only the email now? or email and url only?
