wordpress都有文章置顶的功能不过文章置顶却无法在

分类页面、标签页面，产生文章置顶的功能

如果我想将分类中的「wordpress教学」里面的一篇文章

成为wordpress教学分类的文章置顶。

说明： 这是我文章分类的「wordpress教学」分类页面

现在我想将9月2日的「WordPress 角色和权限终极指南（译文-出处国外）」

变成文章置顶

设定完成后

 

也可以让分类页面有文章置顶功能啰！

现在打开你主题的functions.php

加入以下代码

[cc lang="php"] //WordPress让分类及标签的页面也实现置顶文章功能add_filter('the_posts', 'putStickyOnTop' ); function putStickyOnTop( $posts ) { if(is_home() || !is_main_query( ) || !is_archive()) return $posts; global $wp_query; // 取得所有置顶文章讯息$sticky_posts = get_option('sticky_posts'); if ( $wp_query->query_vars['paged'] <= 1 && ! empty($sticky_posts) && is_array($sticky_posts) && !get_query_var('ignore_sticky_posts') ) { $stickies1 = get_posts( array( 'post__in' => $sticky_posts ) ); foreach ( $stickies1 as $sticky_post1 ) { // 判断是否为分类页if($wp_query->is_category == 1 && !has_category($wp_query->query_vars['cat'], $sticky_post1->ID)) { // 排除不属于本分类的置顶文章$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'], $sticky_post1 ->ID)) { // 排除不属于本标签的文章$offset1 = array_search($sticky_post1->ID, $sticky_posts); unset( $sticky_posts[$offset1] ); } if($wp_query->is_year == 1 && date_i18n('Y', strtotime($sticky_p ost1->post_date))!=$wp_query->query['m']) { // 排除不属于本年份的文章$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))!=$wp_query->query['m']) { // 排除不属于本月份的文章$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))!=$wp_query->query['m']) { // 排除不属于本日期的文章$offset1 = array_search($sticky_post1->ID, $sticky_posts); unset( $sticky_posts[$ offset1] ); } if($wp_query->is_author == 1 && $sticky_post1->post_author != $wp_query->query_vars['author']) { // 排除不属于本作者的文章$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) ) { $stick y_post = $posts[$i]; // Remove sticky from current position array_splice($posts, $i, 1); // Move to front, after other stickies array_splice($posts, $sticky_offset, 0, array($sticky_post )); // Increment the sticky offset.
