title: How to use PHP form validation with jQuery mobile
body: <p>I love jQuery mobile, but I'm epically disappointed there's no support for form validation, not even skinning.  I'd like to use PHP for form validation... is there a way to accomplish this?  I already have all this code in place and would like to avoid rewriting it all in javascript if possible.</p>
  
  <p>Is there a way I can submit the form to a URL via ajax, but return a json error message?</p>
  
  <p>Any thoughts?</p>
