您可以像这样在自定义循环中注册一个新的小部件

<?php
add_action( \'widgets_init\', \'Miy_widget_box\' );?>
<?php function Miy_widget_box() {
register_widget( \'Miy_Widget\' );
}?>
<?php class Miy_Widget extends WP_Widget {
    public function __construct() {
           // widget actual processes
parent::WP_Widget(false,\'Title Widget\',\'description=Description Widget\');
    }
    public function form( $instance ) {
           // outputs the options form on admin
           echo \'include html coding in here\';
    }
    public function update( $new_instance, $old_instance ) {
           // processes widget options to be saved
    }   
    public function widget( $args, $instance ) { 

    }
 }?>
