Hello all, This is my first post here. I'm learning MySQL/PHP using DreamweaverMX and picking things up at a relatively comfortable pace. I've encountered my first dilemma though: I've created a User Registration form that posts data to a Clients table. I've designated the Email Address field as unique. The form works fine and propagates the table without error, however after testing it by trying to submit a duplicate email address, the page returned is blank except for this one line of text: Duplicate entry 'phil at philparr.com' for key 2 Which is fine - it prevents a duplicate email address. BUT how do I "pretty up" the page? As this doesn't list an error number, I am unsure what such a result is called - therefore I don't know what to look up in the indexes for the books I'm learning with. Those books are: glasshaus' Dreamweaver MX: PHP Web Development, and Sams PHP and MySQL Web Development I'd like to be able to display a message like "Sorry - this email address is already in use" and provide a link back to the form. Links to tutorials, appropriate page numbers in the above books, or just plain spelling it out for me would be greatly appreciated. Take it easy though - I'm a newbie. I'm at phil at philparr.com - Thanks in advance!
