最近突然发现博客的评论楼层有点问题,之前一直设置的是“在每个页面顶部显示新的评论”,也就是所谓的倒序显示评论,但是主题只支持顺序的评论楼层好,于是楼层和楼层号之间对不上。搜了一下在zww.me发现有实现的代码,但是放到博客之后无法正常工作,比如限制分页显示为25条的时候,文章只有一条评论时也显示的25楼。折腾了一下搞定了,做个记录,也供大家参考。
在主题文件 functions.php中找到$GLOBALS['comment'] = $comment;在后面加上下面的代码:
1
2
3
4
5
6

/* 主评论计数器 */ global $commentcount , $wpdb , $post ; if (! $commentcount ) { //初始化楼层计数器 if ( get_option( 'comment_order' ) === 'desc' ) { //倒序 $comments = $wpdb ->get_results( "SELECT * FROM $wpdb->comments WHERE comment_post_ID = $post->ID AND comment_type = '' AND comment_approved = '1' AND !comment_parent" ); $cnt = count ( $comments ); //获取主评论总数量 $page = get_query_var( 'cpage' ); //获取当前评论列表页码 $cpp =get_option( 'comments_per_page' ); //获取每页评论显示数量 if ( ceil ( $cnt / $cpp ) == 1 || ( $page > 1 && $page == ceil ( $cnt / $cpp ))) { $commentcount = $cnt + 1; //如果评论只有1页或者是最后一页,初始值为主评论总数 } else { $commentcount = $cpp * $page + 1; } } else { //顺序 $page = get_query_var( 'cpage' )-1; $cpp =get_option( 'comments_per_page' ); //获取每页评论数 $commentcount = $cpp * $page ; } } /* 主评论计数器 end */ if ( ! $parent_id = $comment ->comment_parent ) { $commentcountText = '<div class="floor">' ; if ( get_option( 'comment_order' ) === 'desc' ) { //倒序 $commentcountText .= -- $commentcount . '楼' ; } else { switch ( $commentcount ) { case 0: $commentcountText .= '<span>沙发!</span>' ; ++ $commentcount ; break ; case 1: $commentcountText .= '<span>板凳!</span>' ; ++ $commentcount ; break ; case 2: $commentcountText .= '<span>地板!</span>' ; ++ $commentcount ; break ; default : $commentcountText .= ++ $commentcount . '楼' ; break ; } } $commentcountText .= '</div">' ; } } |
然后在合适的位置加上以下代码输出楼层号
1
|
<?php echo $commentcountText ; //主评论楼层号 - by zwwooooo ?> |
修改之后的代码应该是这样的(以官方最新的 wp_list_comments() 回调函数代码为例):
