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.

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.
