Sometimes, we need to check request is ajax or not in codeigniter 3 application. If you want to call same method but if request is ajax then you perform different, then you can do by using $this->input object.

In Codeigniter 3 $this->input object provide is_ajax_request() method to check request is ajax or not, In following example you can see how it's works.

You can check see bellow controller method example so you can learn how to use is_ajax_request() and determine request is from ajax or not.



* Get All Data from this method.


* @return Response


public function ajaxRequestPost()


if ($this->input->is_ajax_request()) {

$data = array(

'title' => $this->input->post('title'),

'description' => $this->input->post('description')


$this->db->insert('items', $data);

echo 'Added successfully.';


echo 'You can not access';
