您能帮我得到前端ajax返回的响应值为1吗。我已经更新了以下代码，现在返回的响应值为0

if (isset($_POST[\'frontliveeditor_settings\']) && isset($_POST[\'action\']) && $_POST[\'action\'] == "fnrlvedt_updateoption"){
    if (wp_verify_nonce($_POST[\'frontendlvedt\'],\'frnendlv_updateoptions\')){ 
        update_option(\'frontliveeditor_settings\', $_POST[\'frontliveeditor_settings\']);
    }
}

if(! function_exists( \'fend_clear_options\' )):  
    function fend_clear_options(&$fend_value) {
       $fend_value = htmlspecialchars(stripslashes( $fend_value ));
    }
endif;



if(! function_exists( \'fend_save_settings\' )):  
   function fend_save_settings ( $fend_data , $fend_rfresh = 0 ) {
       global $fend_arrayoptions;
       $fend_arrayoptions = array( \'frontliveeditor_settings\' );
       foreach( $fend_arrayoptions as $fend_option ){
           if( isset( $fend_data[$fend_option] )){
               array_walk_recursive( $fend_data[$fend_option] , \'fend_clear_options\');
               update_option( $fend_option ,  $fend_data[$fend_option] );
           }        
       }

       if( $fend_rfresh == 2 ) {    wp_die(\'2\');}
       elseif( $fend_rfresh == 1 ){ wp_die(\'1\');}
  }

endif;
