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; } }Expand full source codeCollapse full source code
