Is Ajax in WordPress

Question

Is there anyway to detect if the current server operation is currently an AJAX request in WordPress?

For example:

is_ajax()

Answer 1

I am not sure if WordPress has a function for this but it can be done by creating a simple one yourself.

if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest')
{
    // Is AJAX request
    return true; 
}
