PHP and Forms

[Anon]

Can anyone tell me how to change the value of a form field using PHP embedded in the same HTML doc, later on.

I declare a hidden form field with no value at the start of the form.

Then using PHP I loop through certain criteria and judging on the correct criteria I want to insert it into the hidden form fields value.

Please help. I am at a wits end. It would be much appreaciated.

Let me see if I am track here:

You have a hidden input on your page and you have it set to one value when the page first loads then you want to change it based on some input by a user. Is this after they hit submit, or does it need to change dynamically. If its after they hit submit I think you could use this

at the start set $hiddeninput = "";

then wherever you have the hidden input

<input type="hidden" name="name" value="<?php print $hiddeninput1; ?>">

Now after they hit submit you say you are looping through some criteria and wherever you meet your criteria just set $hiddeninput1 = to whatever you need to now when the page loads the hidden input will have the value you need. Let me know if this what you are after?

That is the best idea so far. I will try it and get back to you. Thanks
