wordpress都有文章置頂的功能不過文章置頂卻無法在

分類頁面、標籤頁面，產生文章置頂的功能

如果我想將分類中的「wordpress教學」裡面的一篇文章

成為wordpress教學分類的文章置頂。

說明： 這是我文章分類的「wordpress教學」分類頁面

現在我想將9月2日的「WordPress 角色和權限終極指南（譯文-出處國外）」

變成文章置頂

設定完成後

也可以讓分類頁面有文章置頂功能囉！

現在打開你主題的functions.php

加入以下代碼

[cc lang="php"] //WordPress讓分類及標籤的頁面也實現置頂文章功能 add_filter('the_posts', 'putStickyOnTop' ); function putStickyOnTop( $posts ) { if(is_home() || !is_main_query() || !is_archive()) return $posts; global $wp_query; // 取得所有置頂文章訊息 $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 $sticky_post1 ) { // 判斷是否為分類頁 if($wp_query->is_category == 1 && !has_category($wp_query->query_vars['cat'], $sticky_post1->ID)) { // 排除不屬於本分類的置頂文章 $offset1 = array_search($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)) { // 排除不屬於本標籤的文章 $offset1 = array_search($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']) { // 排除不屬於本年份的文章 $offset1 = array_search($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']) { // 排除不屬於本月份的文章 $offset1 = array_search($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']) { // 排除不屬於本日期的文章 $offset1 = array_search($sticky_post1->ID, $sticky_posts); unset( $sticky_posts[$offset1] ); } if($wp_query->is_author == 1 && $sticky_post1->post_author != $wp_query->query_vars['author']) { // 排除不屬於本作者的文章 $offset1 = array_search($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, $sticky_offset, 0, array($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, $sticky_offset, 0, array( $sticky_post ) ); $sticky_offset++; } } } return $posts; } [/cc]
