最近突然發現博客的評論樓層有點問題,之前一直設置的是“在每個頁面頂部顯示新的評論”,也就是所謂的倒序顯示評論,但是主題只支持順序的評論樓層好,于是樓層和樓層號之間對不上。搜了一下在zww.me發現有實現的代碼,但是放到博客之后無法正常工作,比如限制分頁顯示為25條的時候,文章只有一條評論時也顯示的25樓。折騰了一下搞定了,做個記錄,也供大家參考。
在主題文件 functions.php中找到$GLOBALS['comment'] = $comment;在后面加上下面的代碼:
- /* 主評論計數器 */
- global $commentcount,$wpdb, $post;
- if(!$commentcount) { //初始化樓層計數器
- 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);//獲取主評論總數量
- $page = get_query_var('cpage');//獲取當前評論列表頁碼
- $cpp=get_option('comments_per_page');//獲取每頁評論顯示數量
- if (ceil($cnt / $cpp) == 1 || ($page > 1 && $page == ceil($cnt / $cpp))) {
- $commentcount = $cnt + 1;//如果評論只有1頁或者是最后一頁,初始值為主評論總數
- } else {
- $commentcount = $cpp * $page + 1;
- }
- }else{ //順序
- $page = get_query_var('cpage')-1;
- $cpp=get_option('comments_per_page');//獲取每頁評論數
- $commentcount = $cpp * $page;
- }
- }
- /* 主評論計數器 end */
- if ( !$parent_id = $comment->comment_parent ) {
- $commentcountText = '<div class="floor">';
- if ( get_option('comment_order') === 'desc' ) { //倒序
- $commentcountText .= --$commentcount . '樓';
- } else {
- switch ($commentcount) {
- case 0:
- $commentcountText .= '<span>沙發!</span>'; ++$commentcount;
- break;
- case 1:
- $commentcountText .= '<span>板凳!</span>'; ++$commentcount;
- break;
- case 2:
- $commentcountText .= '<span>地板!</span>'; ++$commentcount;
- break;
- default:
- $commentcountText .= ++$commentcount . '樓';
- break;
- }
- }
- $commentcountText .= '</div">';
- }
- }
然后在合適的位置加上以下代碼輸出樓層號
<?php echo $commentcountText; //主評論樓層號 - by zwwooooo ?>
修改之后的代碼應該是這樣的(以官方最新的 wp_list_comments() 回調函數代碼為例):
- <?php
- function mytheme_comment($comment, $args, $depth) {
- $GLOBALS['comment'] = $comment;
- /* 主評論計數器 by zwwooooo Modified Gimhoy(http://blog.gimhoy.com) */
- global $commentcount,$wpdb, $post;
- if(!$commentcount) { //初始化樓層計數器
- 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);//獲取主評論總數量
- $page = get_query_var('cpage');//獲取當前評論列表頁碼
- $cpp=get_option('comments_per_page');//獲取每頁評論顯示數量
- if (ceil($cnt / $cpp) == 1 || ($page > 1 && $page == ceil($cnt / $cpp))) {
- $commentcount = $cnt + 1;//如果評論只有1頁或者是最后一頁,初始值為主評論總數
- } else {
- $commentcount = $cpp * $page + 1;
- }
- }else{ //順序
- $page = get_query_var('cpage')-1;
- $cpp=get_option('comments_per_page');//獲取每頁評論數
- $commentcount = $cpp * $page;
- }
- }
- /* 主評論計數器 end */
- if ( !$parent_id = $comment->comment_parent ) {
- $commentcountText = '<div class="floor">';
- if ( get_option('comment_order') === 'desc' ) { //倒序
- $commentcountText .= --$commentcount . '樓';
- } else {
- switch ($commentcount) {
- case 0:
- $commentcountText .= '<span>沙發!</span>'; ++$commentcount;
- break;
- case 1:
- $commentcountText .= '<span>板凳!</span>'; ++$commentcount;
- break;
- case 2:
- $commentcountText .= '<span>地板!</span>'; ++$commentcount;
- break;
- default:
- $commentcountText .= ++$commentcount . '樓';
- 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; //主評論樓層號 - by zwwooooo ?>
- <?php if ( 'div' != $args['style'] ) : ?>
- </div>
- <?php endif; ?>
- <?php
- }
