在wordpress中默認能置頂文章就是只有首頁了,如果我們希望分類/標簽等存檔頁也能置頂文章我們需要二次開發.
現在參考wp-includes/query.php中首頁置頂的代碼,稍微修改一下,可以讓分類頁、標簽頁、作者頁和日期頁等存檔頁面也能像首頁一樣在頂部顯示其范圍內的置頂文章,把下面的代碼放到當前主題下的functions.php中就可以了.
- add_filter('the_posts', 'putStickyOnTop' );
- function putStickyOnTop( $posts ) {
- if(is_home() || !is_main_query() || !is_archive())
- return $posts;
- global $wp_query;
- $sticky_posts = get_option('sticky_posts');
- if ( $wp_query->query_vars['paged'] <= 1 && is_array($sticky_posts) && !emptyempty($sticky_posts) && !get_query_var('ignore_sticky_posts') ) { $stickies1 = get_posts( array( 'post__in' => $sticky_posts ) );
- foreach ( $stickies1 as $sticky_post1 ) {
- // 判斷當前是否分類頁
- if($wp_query->is_category == 1 && !has_category($wp_query->query_vars['cat'], $sticky_post1->ID)) {
- // 去除不屬于本分類的文章
- $offset1 = array_search($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)) {
- // 去除不屬于本標簽的文章
- $offset1 = array_search($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']) {
- // 去除不屬于本年份的文章
- $offset1 = array_search($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']) {
- // 去除不屬于本月份的文章
- $offset1 = array_search($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']) {
- // 去除不屬于本日期的文章
- $offset1 = array_search($sticky_post1->ID, $sticky_posts);
- unset( $sticky_posts[$offset1] );
- }
- if($wp_query->is_author == 1 && $sticky_post1->post_author != $wp_query->query_vars['author']) {
- // 去除不屬于本作者的文章
- $offset1 = array_search($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, $sticky_offset, 0, array($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 ( !emptyempty($sticky_posts) && !emptyempty($wp_query->query_vars['post__not_in'] ) )
- $sticky_posts = array_diff($sticky_posts, $wp_query->query_vars['post__not_in']);
- // Fetch sticky posts that weren't in the query results
- if ( !emptyempty($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;
- }
代碼說明:
1、如果你想讓存檔頁也都顯示全部置頂文章,那么就刪掉11-43行的代碼;
2、如果不想在某分類頁顯示置頂文章,將第 3 行的
- if(
- //改成:
- // abc是分類名稱
- if ( is_category( 'abc' ) ||
3、如果不想某標簽頁顯示置頂文章,將第 3 行的代碼
- if(
- //改成:
- // abc是標簽名稱
- if ( is_tag( 'abc' ) ||
4、如果不想某作者頁顯示置頂文章,將第 3 行的
- if(
- //改成:
- // abc是作者昵稱
- if ( is_author( 'abc' ) ||
5、以上代碼只對主循環有效,如果你在存檔頁使用WP_Query或query_posts來獲取文章列表,又像讓這些列表頂部顯示置頂文章,可以把第3行代碼中的以下代碼刪掉(注意:可能會導致文章顯示數量跟你設置的不一樣):
代碼如下:|| !is_main_query()
置頂樣式:如果你想給置頂文章添加樣式,將以下代碼添加到functions.php中,會給置頂文章添加一個名為 sticky 的class,具體的css代碼,再自行自定義:
- add_filter('post_class', 'addStickyClass' ,10,3 );
- function addStickyClass( $classes, $class, $post_id ){
- if( is_sticky() && is_category() && !isset( $classes['sticky'] ) ){
- $classes[] = 'sticky';
- }
- return $classes;
- }
