CSRF giving problem with ajax

when you send custom fields by ajax, then CSRF token is not send in request data so you should post the CSRF token to your data option in AJAX request data..

PHP Code:

$.post(url, {'<?php echo $this->security->get_csrf_token_name(); ?>':'<?php echo $this->security->get_csrf_hash(); ?>', other_fields: "bla"}, function(data){
   //code here
}) 


when you posting form data by ajax, then CSRF library automatic append hidden token element in form, so form works well
