自己平时会经常修改主题，
偶尔会遇到需要添加 最近评论侧边栏
自己修改过wp自带的评论侧边栏，但是换主题后就要重新做
突然发现大发写过这个，特此记录
以下代码转自大发
class bigfa_widget3 extends WP_Widget { function bigfa_widget3() { $widget_ops = array('description' => '支持评论表情'); $this->WP_Widget('bigfa_widget3', 'P-主题最新评论', $widget_ops); } function widget($args, $instance) { extract($args); $title = apply_filters('widget_title',esc_attr($instance['title'])); $limit = strip_tags($instance['limit']); $email = strip_tags($instance['email']); echo $before_widget.$before_title.$title.$after_title; ?> <ul class="recentcomments"> <?php global $wpdb; $limit_num = $limit ; $my_email ="'" . $email .
