Can you explain a little more what you are trying to do?

Is this the code from "returnsearch.php"?

In the past, when displaying rows of data that I wanted to show details on, I've used links that were built on the fly instead of buttons. I have used images so it looked like a button, but it really was just a link or I've made the ID number into a link that calls the details page...

href="returnsearch.php?id=1"
href="returnsearch.php?id=2"
. . .

Then in the returnsearch.php page I use the $_GET['id'] to get the number they selected.

I don't know if that's what you are trying to accomplish or not or if there are other reasons you are trying to use the on-click.
