Form framework for inputs specified by custom popup window
<p>I have a PHP based form.  For many of our inputs, the user clicks an html which created a custom popup window with a "mini-form".  When the user clicks on the submit button, the values from the "mini-form" are sent to the main form to hidden inputs using JavaScript.  This can become complicated to do, especially with validation and other complications.  I know there are a million PHP frameworks for forms, but I can't find one to deal with these situations.</p>

<p>Does anyone have advice?</p>
