Trying to create a multiform that determines next_form based on radio button choice?

Don't know if this is possible. I'm new to PHP, so I'm just trying random stuff here. I turned my index.html into an index.php so I would have access to if/else statements. Basically I've got this right now:

....


<dl>
<dt>Are you a new or existing customer?*</dt>
    <dd>
        <input type="radio" name="Customer" id="customer-new" value="false" /><label for="customer-new">New</label>
        <input type="radio" name="Customer" id="customer-old" value="true" /><label for="customer-old">Existing</label>
    </dd>
</dl>
                        
<input type="hidden" name="next_form" value="
    <?php
        $selected_radio = $_POST['Customer'];
                            
        if(!($selected_radio))
        {
            echo('new.html');
        } 
        else
        {
            echo('existing.html');
        }
    ?>"
/>

<input type="submit" name="submit" value="Next" />

Right now, no matter if "New" (false) or "Existing" (true) is selected it sends me to "new.html", but the FormMail email I get does correctly say true or false based on my choice.

I've got a feeling it's not working because of PHP being server side, so it doesn't evaluate the conditional until after it's already on it's way to the next page? Is this something I would need to the FormMail Computation Module for?

Aright, I figured it out with JQuery instead of PHP.

In case anyone was wondering...

<script>
    $(":radio").click(function () {
        if($('#customer_new').is(':checked'))
        {
            $("#next_form").val("new.html");
        } else {
            $("#next_form").val("existing.html");
        }
    });
</script>

Still interested to know if it's possible to do with PHP though, in case users have JS turned off.

yep, PHP happens server side so it can't affect what's happening in the browser until u submit the form

u need javascript for that

tectites computation module works server side too, i think the main advantage is it lets u do calculations on the submitted fields without resorting to extra php code.
