Examples
#1 Differentiate output behavior based on how it is being called
In a PHP code, if we want to differentiate its output behavior based on how it is being called (like a normal function or like a WP AJAX callback), then we should use the wp_doing_ajax() function like below:
function wpdocs_render() {
// SOME LOGIC ...
$return_data = array( 'success' => true );
if ( wp_doing_ajax() ) {
wp_send_json_success( $return_data );
}
else {
return $return_data;
}
} #2 Do something if the current request is an AJAX request
Add AJAX hooks only for AJAX request.
if( wp_doing_ajax() ){
add_action( 'wp_ajax_myaction', 'ajax_handler' );
add_action( 'wp_ajax_nopriv_myaction', 'ajax_handler' );
function ajax_handler(){
// ajax request handler
}
}
