Form framework for inputs specified by custom popup window

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. 开发者_运维技巧I know there are a million PHP frameworks for forms, but I can't find one to deal with these situations.

Does anyone have advice?

My understanding is that you are opening new form using var win = window.open() now using the win reference you might be populating the actual forms data. This is old good approach which is been working well from long time.

If this is correct Then I think that if you would really want to do it in better way you should start with JQuery UI.
