wordpress自带的文章置顶功能，只支持在首页让置顶文章在顶部显示，在分类、标签、作者和日期等存档页面，就没法让置顶文章在顶部显示了，只能按默认的顺序显示。在使用href="https://www.jb51.cc/">wordpress建站的过程中，很多时候，我们需要把置顶文章显示在这些存档页面的顶部。
这篇wordpress教程里，我们参考 wp-includes/query.PHP 中首页置顶的代码，稍做修改，向大家讲解一下存档页面的顶部显示置顶文章的方法。
切换到主题目录，打开functions.PHP文件，添加如下代码：
query_vars['paged'] <= 1 && !empty($sticky_posts) && is_array($sticky_posts) && !get_query_var('ignore_sticky_posts') ) { $stickies1 = get_posts( array( 'post__in' => $sticky_posts ) ); foreach ( $stickIEs1 as $sticky_post1 ) { // 判断当前是否分类页 if($wp_query->is_category == 1 && !has_category($wp_query->query_vars['cat'],$sticky_post1->ID)) { // 去除不属于本分类的置顶文章 $offset1 = array_search($sticky_post1->ID,$sticky_posts); unset( $sticky_posts[$offset1] ); } if($wp_query->is_tag == 1 && !has_tag($wp_query->query_vars['tag'],$sticky_post1->ID)) { // 去除不属于本标签的文章 $offset1 = array_search($sticky_post1->ID,$sticky_posts); unset( $sticky_posts[$offset1] ); } if($wp_query->is_year == 1 && date_i18n('Y',strtotime($sticky_post1->post_date))!=$wp_query->query['m']) { // 去除不属于本年份的文章 $offset1 = array_search($sticky_post1->ID,$sticky_posts); unset( $sticky_posts[$offset1] ); } if($wp_query->is_month == 1 && date_i18n('Ym',strtotime($sticky_post1->post_date))!=$wp_query->query['m']) { // 去除不属于本月份的文章 $offset1 = array_search($sticky_post1->ID,$sticky_posts); unset( $sticky_posts[$offset1] ); } if($wp_query->is_day == 1 && date_i18n('Ymd',strtotime($sticky_post1->post_date))!=$wp_query->query['m']) { // 去除不属于本日期的文章 $offset1 = array_search($sticky_post1->ID,$sticky_posts); unset( $sticky_posts[$offset1] ); } if($wp_query->is_author == 1 && $sticky_post1->post_author != $wp_query->query_vars['author']) { // 去除不属于本作者的文章 $offset1 = array_search($sticky_post1->ID,$sticky_posts); unset( $sticky_posts[$offset1] ); } } $num_posts = count($posts); $sticky_offset = 0; // Loop over posts and relocate stickIEs to the front. for ( $i = 0; $i < $num_posts; $i++ ) { if ( in_array($posts[$i]->ID,$sticky_posts) ) { $sticky_post = $posts[$i]; // Remove sticky from current position array_splice($posts,$i,1); // Move to front,after other stickIEs array_splice($posts,$sticky_offset,array($sticky_post)); // Increment the sticky offset. The next sticky will be placed at this offset. $sticky_offset++; // Remove post from sticky posts array $offset = array_search($sticky_post->ID,$sticky_posts); unset( $sticky_posts[$offset] ); } } // If any posts have been excluded specifically,Ignore those that are sticky. if ( !empty($sticky_posts) && !empty($wp_query->query_vars['post__not_in'] ) ) $sticky_posts = array_diff($sticky_posts,$wp_query->query_vars['post__not_in']); // Fetch sticky posts that weren't in the query results if ( !empty($sticky_posts) ) { $stickIEs = get_posts( array( 'post__in' => $sticky_posts,'post_type' => $wp_query->query_vars['post_type'],'post_status' => 'publish','nopaging' => true ) ); foreach ( $stickIEs as $sticky_post ) { array_splice( $posts,array( $sticky_post ) ); $sticky_offset++; } } } return $posts;}
