Check for Ajax Request in CodeIgniter

Check for Ajax Request in CodeIgniter:

The CodeIgniter Input Class Provides lots of  helper functions to deal with user inputs , security etc.this class is initialized automatically by the system so there is no need to do it manually.

I always recommend you to use this class instead using PHP Core Input Variables while dealing with forms and requests.

To check Ajax Request in CodeIgniter, we will use codeIgniter Output Class Method class is_ajax_request() , this function checks to see if the HTTP_X_REQUESTED_WITH server header has been set, if set response will be true otherwise false means it will returns a boolean response.

 

we can use

 $this->input->is_ajax_request()

from the input class:

if (!$this->input->is_ajax_request()) {
     exit('No direct script access allowed');
}

As, CodeIgniter Library::

is_ajax_request()

Returns:TRUE if it is an Ajax request, FALSE if not
Return type:bool

Checks to see if the HTTP_X_REQUESTED_WITH server header has been set, and returns boolean TRUE if it is or FALSE if not.
