IS_AJAX constant being ignored - how come? |

I'm learning AJAX w CI 1.7 right now from this tutorial: http://www.weblee.co.uk/2009/06/07/simpl...er-part-1/ So far, things are good. I'm in the 2nd part, where it explains to add this line of code to the bottom of your constants.php file to check for AJAX activity. Code: define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest'); Then here's an example of the function I'm playing with: Code: // Task function When I run this function directly from a URL, it still echo's 11. For some reason it isn't reading the IS_AJAX constant. If I change the code to this: Code: // Task function It works fine. What am I doing wrong with my constants.php? And yes, I realize there's an $this->input->is_ajax_request() in CI 2.0, but I'm comfortable with CI 1.7. Unless there's a major reason to upgrade, I'll stick with it. |
