I have a script with $_POST and <form> to load data with text input. Situation: enter name of author(s) for book. I have the script set up to enter first_name, last_name for Author1 and the same for Author 2. Check if entry 1 exists then proceed accordingly Check if entry 2 exists then proceed accordingly. Now, If I have three or more authors to enter, is there a way to add a radio button to add more rows for input or to skip further inputs, if I have to enter the inputs for each additional author? I'm looking for a simple way to do this. Could or should Ajax be involved in this somehow?

Ajax would be a good way to go if it could be an undetermined number of authors. But if you have a limit (like 3 or 4 or 5) then just include the text fields for that number. For Ajax you might have a button or link that says "add more authors" and when clicked the javascript adds an additional input to the form.

This isn't a job for AJAX, it is a job for JavaScript. REF: AJAX - http://en.wikipedia.org/wiki/Ajax_(programming) Dynamic Form Generation - http://www.faqts.com/knowledge_base/view.phtml/aid/1785/fid/129 I did a quick Google and came up with the two above examples. Others might have better suggestions. But I just wanted to point out the difference. AJAX, IMO, is bases on JavaScript talking to a server with the intent to send/receive data. DHTML/JavaScript/etc... are was to do what you are asking without ever needing to talk with the server. So it doesn't involve anything that AJAX was designed to solve. I simply wanted to point out the different uses. Hope I didn't step on anybodies toes. -- Jim Lucas "Some men are born to greatness, some achieve greatness, and some have greatness thrust upon them."
