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 personally prefer the wp_doing_ajax(), but here is another example that should do it.

if( true === strpos( $_SERVER[ 'REQUEST_URI' ], 'wp-admin/admin-ajax.php' ) ) {
    // is doing ajax
}
