我有一个类别页面，该页面正在重新分配到archieve.php。
顶部有两个即时贴。
1）使用COMBANK卡在＆Co Pub and Kitchen享受高达25％的折扣
2）所有汇丰信用卡在Robata –科伦坡瑞享酒店20％优惠
我的分页为每个帖子10个项目
现在，它向我显示每个帖子 12个项目。
这是我的代码：
function yell_category_sticky_posts( $posts, $wp_query ) {
global $wp_the_query;
// Don't continue if this isn't a category query, we're not in the main query or we're in the admin
if ( ! $wp_query->is_category || $wp_query !== $wp_the_query || is_admin() )
return $posts;
global $wpdb;
$q = $wp_query->query_vars;
$page = absint( $q['paged'] );
if ( empty( $page ) )
$page = 1;
$post_type = $q['post_type'];
$sticky_posts = get_option( 'sticky_posts' );
if ( $wp_query->is_category && $page <= 1 && is_array( $sticky_posts ) && !empty( $sticky_posts ) && ! $q['ignore_sticky_posts'] ) {
$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( $q['post__not_in'] ) )
$sticky_posts = array_diff( $sticky_posts, $q['post__not_in'] );
// Fetch sticky posts that weren't in the query results
if ( !empty( $sticky_posts ) ) {
$stickies__in = implode( ',', array_map( 'absint', $sticky_posts ));
// honor post type(s) if not set to any
$stickies_where = '';
if ( 'any' != $post_type && '' != $post_type ) {
if ( is_array( $post_type ) )
$post_types = join( "', '", $post_type );
else
$post_types = $post_type;
$stickies_where = "AND $wpdb->posts.post_type IN ('" . $post_types . "')";
}
$stickies = $wpdb->get_results( "SELECT wp_posts.* FROM $wpdb->posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id IN (" . get_term( $wp_query->query_vars['cat'], 'category' )->term_taxonomy_id . ") ) AND $wpdb->posts.ID IN ($stickies__in) $stickies_where" );
foreach ( $stickies as $sticky_post ) {
// Ignore sticky posts are not published.
if ( 'publish' != $sticky_post->post_status )
continue;
array_splice( $posts, $sticky_offset, 0, array( $sticky_post ) );
$sticky_offset++;
}
}
}
return $posts;
}
add_filter( 'the_posts', 'yell_category_sticky_posts', 10, 2 );
我的问题：
我要在每页上显示 10 个帖子，当前显示的是 12 个帖子 每页带有粘性帖子。
这个问题是给大师的，不是给新学习者的。
有人在这里吗？预先感谢

正如我在评论中建议的那样，将“粘性帖子”保存在元（假设is_featured_post作为“元密钥”）中。
仅运行一次 即可设置现有帖子的元值。您可以跳过此步骤，因为您已经保存了元数据。
// set meta value of all posts to 0
$all_posts = get_posts(array('post_type'=>'post','posts_per_page'=>-1));
if( is_array( $all_posts ) )
{
foreach( $all_posts as $post ) {
update_post_meta( $post->ID, 'is_featured_post', '0' );
}
}
// set meta value of all sticky posts alone to 1
$sticky_posts = get_option( 'sticky_posts' );
if( is_array( $sticky_posts ) )
{
foreach ( $sticky_posts as $sticky_post ) {
update_post_meta( $sticky_post, 'is_featured_post', '1' );
}
}
以下功能每次更新帖子（或保存新帖子）时都会更新新的粘性meta is_featured_post。
function save_sticky_meta( $post_id ) {
if ( isset( $_REQUEST['sticky'] ) ) {
update_post_meta( $post_id, 'is_featured_post', '1' );
}
else {
update_post_meta( $post_id, 'is_featured_post', '0' );
}
}
add_action( 'save_post', 'save_sticky_meta' );
add_action( 'edit_post', 'save_sticky_meta' );
然后使用pre_get_posts操作来设置类别查询。我们按“元”和“日期”的降序排列以在顶部显示最新的值。
function include_sticky_posts( $query ) {
if ( ! is_admin() && $query->is_main_query() && $query->is_category() ) {
$query->set( 'meta_key', 'is_featured_post' );
$query->set( 'sticky_sort', true ); //custom sticky order query
$query->set( 'orderby', 'meta_value_num date' );
$query->set( 'order', 'DESC' );
}
}
add_action( 'pre_get_posts', 'include_sticky_posts' );
如果您想随机化非粘性帖子，请使用the_posts过滤器更改顺序，如下所示。
add_filter( 'the_posts', 'sticky_posts_sort', 10, 2 );
function sticky_posts_sort( $posts, $query )
{
// if custom sort set from category query
if ( true !== $query->get( 'sticky_sort' ) )
return $posts;
// loop through posts & save sticky & other posts in seperate arrays
$sticky_posts = get_option( 'sticky_posts' );
$sticky_array = array();
$posts_array = array();
foreach ( $posts as $p ) {
if( in_array( $p->ID, $sticky_posts ) )
$sticky_array[] = $p;
else
$posts_array[] = $p;
}
// merge both arrays and randomize non-sticky posts alone
if( is_array( $posts_array ) )
shuffle( $posts_array );
if( is_array( $sticky_array ) && is_array( $posts_array ) )
$posts = array_merge( $sticky_array, $posts_array );
elseif( is_array( $sticky_array ) )
$posts = $sticky_array;
else
$posts = $posts_array;
return $posts;
}

以下功能可将粘滞物推到顶部，您应该可以使用它来帮助解决问题。
add_filter('the_posts', 'bump_sticky_posts_to_top');
function bump_sticky_posts_to_top($posts) {
$stickies = array();
foreach($posts as $i => $post) {
if(is_sticky($post->ID)) {
$stickies[] = $post;
unset($posts[$i]);
}
}
return array_merge($stickies, $posts);
}
