Dynamically changing a form field

[Anon]

Hello:

I am trying to create a form that will dynamically change the value in a text field depending on what is selected/typed into other fields within the same form. IF I was using Javascript, I would simply do a
document.formname.textfieldname.value = "whatever";
Is there some way to modify the field using only PHP or a combination of PHP and Javascript? . . . something like:
document.formname.textfieldname.value = <?$phpvar?>;

Thanks

Shawn

Since PHP is server based scripting, the only way to do what you describe is to have a javascript post the form every time a field is exited (onMouseOut), have the PHP evaluate the field contents, modify the field values, and then output the form again. Not very efficient. I would go with javascript if possible.
