jQuery Forum

I am going to try to explain this the best way possible. If I have a form that prompts a lightbox working as an iframe when submit is clicked, how can I pass the field values to the url or is there another way? Basically, I don't want a reload and I need a way for the lightbox to retrieve the field values once the submit button is clicked. The form does not actually have an action that leads to a php page because I don't want a reload. All I want is the lighbox to pop up saying"blah blah blah: when the submit is pressed without another page loading. Then I would need to retrieve the values from the fields someway. This is why I mentioned placing variables in the url. Can I do a onclick: place field values in the url and then use php GET to retrieve the values from the url?
