PHP CI Validation is first thing I got working correctly. I am now using the validate plugin to validate with JS separately.

I did want to use AJAX to ask PHP to validate the page. Not neccessary but I thought this was 'best practice'. Its been a while since I used AJAX with regular PHP but I used to get JS to access a separate process_form.php script which handled validation based on $_POST/$_GET variables. Memory hazy I don't remember exactly. I wanted to do this with CI.

My current setup will have to do for now.
