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:
/* 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
<?php echo $commentcountText; //主评论楼层号 - by zwwooooo ?>
修改之后的代码应该是这样的(以官方最新的 wp_list_comments() 回调函数代码为例):
<?phpfunction mytheme_comment($comment, $args, $depth) { $GLOBALS["comment"] = $comment; /* 主评论计数器 by zwwooooo Modified Gimhoy(http://blog.gimhoy.com) */ 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;}}$commentcountText .= "</div">"; } } extract($args, EXTR_SKIP); if ( "div" == $args["style"] ) { $tag = "div"; $add_below = "comment"; } else { $tag = "li"; $add_below = "div-comment"; }?> <<?php echo $tag ?> <?php comment_class(empty( $args["has_children"] ) ?
