Passing variables to PHP using Javascript

using form button to add text boxes

[mattennant]

Hello
I'm trying to enable users to add form text fields to a page using a form button without reloading the page. Is there a way i can do this without resending the page and using $_GET.

I have managed to pass the php variable to javascript as below

<script language=JavaScript>
var a = <?PHP echo "$number";?>
a+=1;
document.write(a) //will produce 6
</script>

but i need this to work the other way round with the button click adding 1 to $number. Do i need to be looking into ajax?

Any help much appreciated
