How do I check if the request is made via AJAX in CodeIgniter?
ajax, codeigniter, php
Solution
If you are using a library that sends the `X-Requested-With` header, then you can do...
if (strtolower(filter_input(INPUT_SERVER, 'HTTP_X_REQUESTED_WITH')) === 'xmlhttprequest') {
// I'm AJAX!
}
Problem
How do I check if the request is an AJAX? I am using CodeIgniter. I have a link that when it clicked, it'll open the pop-up dialog window this is done through ajax it requests to a controller name `login_window()`. CodeIgniter ``` //Here is the controller name: function login_window(){ // request via ajax $this->load->view("login_window"); } ``` jQuery ``` //here is the jquery code: //I am using a jquery plugin FACEBOX $('a[rel*=dialog]').facebox(); <a href="http://localhost/codeigniter/login_window" rel="dialog">Login</a> ``` I want to check if it is an AJAX request and if not, i will redirect them to homepage. so there's no way they can access the page that is intended only for ajax requests.
