利用PHP怎么在WordPress中實(shí)現(xiàn)一個(gè)留言樓層號(hào)功能?相信很多沒(méi)有經(jīng)驗(yàn)的人對(duì)此束手無(wú)策,為此本文總結(jié)了問(wèn)題出現(xiàn)的原因和解決方法,通過(guò)這篇文章希望你能解決這個(gè)問(wèn)題。
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(píng)論計(jì)數(shù)器 */ global $commentcount,$wpdb, $post; if(!$commentcount) { //初始化樓層計(jì)數(shù)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(píng)論總數(shù)量 $page = get_query_var('cpage');//獲取當(dāng)前評(píng)論列表頁(yè)碼 $cpp=get_option('comments_per_page');//獲取每頁(yè)評(píng)論顯示數(shù)量 if (ceil($cnt / $cpp) == 1 || ($page > 1 && $page == ceil($cnt / $cpp))) { $commentcount = $cnt + 1;//如果評(píng)論只有1頁(yè)或者是最后一頁(yè),初始值為主評(píng)論總數(shù) } else { $commentcount = $cpp * $page + 1; } }else{ //順序 $page = get_query_var('cpage')-1; $cpp=get_option('comments_per_page');//獲取每頁(yè)評(píng)論數(shù) $commentcount = $cpp * $page; } } /* 主評(píng)論計(jì)數(shù)器 end */ if ( !$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: $commentcountText .= '<span>沙發(fā)!</span>'; ++$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(hào)
<?php echo $commentcountText; //主評(píng)論樓層號(hào) - by zwwooooo ?>
修改之后的代碼應(yīng)該是這樣的(以官方最新的 wp_list_comments() 回調(diào)函數(shù)代碼為例):
<?php function mytheme_comment($comment, $args, $depth) { $GLOBALS['comment'] = $comment; /* 主評(píng)論計(jì)數(shù)器 by zwwooooo Modified Gimhoy(http://blog.gimhoy.com) */ global $commentcount,$wpdb, $post; if(!$commentcount) { //初始化樓層計(jì)數(shù)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(píng)論總數(shù)量 $page = get_query_var('cpage');//獲取當(dāng)前評(píng)論列表頁(yè)碼 $cpp=get_option('comments_per_page');//獲取每頁(yè)評(píng)論顯示數(shù)量 if (ceil($cnt / $cpp) == 1 || ($page > 1 && $page == ceil($cnt / $cpp))) { $commentcount = $cnt + 1;//如果評(píng)論只有1頁(yè)或者是最后一頁(yè),初始值為主評(píng)論總數(shù) } else { $commentcount = $cpp * $page + 1; } }else{ //順序 $page = get_query_var('cpage')-1; $cpp=get_option('comments_per_page');//獲取每頁(yè)評(píng)論數(shù) $commentcount = $cpp * $page; } } /* 主評(píng)論計(jì)數(shù)器 end */ if ( !$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: $commentcountText .= '<span>沙發(fā)!</span>'; ++$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(empty( $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(píng)論樓層號(hào) - by zwwooooo ?> <?php if ( 'div' != $args['style'] ) : ?> </div> <?php endif; ?> <?php }
