I've got simple wizard implemented as a JS slider. In some steps there is a skip button and in the last step you can save the data. So this is actually just a form with controls in every slide, and the data in the steps that were skipped must not be saved when submitting the form. What I wanna do is to set up a flag when the skip button is clicked and check it when submitting the form. So how can I accomplish this without using Ajax or workarounds like creating a hidden field and setting it a value when the skip button is clicked? So basically I want to avoid an unnecessary trips to server via Ajax or extra fields in the form.
