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 $commentcountText; //主评论楼层号 - by zwwooooo ?>
修改之后的代码应该是这样的(以官方最新的 wp_list_comments() 回调函数代码为例):
- <?php
- function mytheme_comment($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(emptyempty( $args['has_children'] ) ? '' : 'parent') ?> id="comment-<?php comment_ID() ?>">
- <?php if ( 'div' != $args['style'] ) : ?>
- <div id="div-comment-<?php comment_ID() ?>" class="comment-body">
- <?php endif; ?>
- <div class="comment-author vcard">
- <?php if ($args['avatar_size'] != 0) echo get_avatar( $comment, $args['avatar_size'] ); ?>
- <?php printf(__('<cite class="fn">%s</cite> <span class="says">says:</span>'), get_comment_author_link()) ?>
- </div>
- <?php if ($comment->comment_approved == '0') : ?>
- <em class="comment-awaiting-moderation"><?php _e('Your comment is awaiting moderation.') ?></em>
- <br />
- <?php endif; ?>
- <div class="comment-meta commentmetadata"><a href="<?php echo htmlspecialchars( get_comment_link( $comment->comment_ID ) ) ?>">
- <?php
- /* translators: 1: date, 2: time */
- printf( __('%1$s at %2$s'), get_comment_date(), get_comment_time()) ?></a><?php edit_comment_link(__('(Edit)'),' ','' );
- ?>
- </div>
- <?php comment_text() ?>
- <div class="reply">
- <?php comment_reply_link(array_merge( $args, array('add_below' => $add_below, 'depth' => $depth, 'max_depth' => $args['max_depth']))) ?>
- </div>
- <?php echo $commentcountText; //主评论楼层号 - by zwwooooo ?>
- <?php if ( 'div' != $args['style'] ) : ?>
- </div>
- <?php endif; ?>
- <?php
- }
样式就自己添加吧~~
