How to do the following:
I want to have a link [upload image] which pop ups modal form, and when user populates it, the form is processed. (The question is not about uploading, this may be a contact form or anything).
My problem is, how to display the form and server side validation messages when validation fails.
I have found this tutorial: http://www.whitewashing.de/blog/articles/92, but it seems quite old.
