分页存档页面上的WordPress粘帖

我有正在重新分配到archieve.php的类别页面。

你可以在这里看到:https://www.dealfinder.lk/category/dining/

顶部有两个粘性帖子。

1)使用COMBANK卡在&Co Pub and Kitchen享受高达25%的折扣

2)所有汇丰信用卡均可在Robata –科伦坡瑞享酒店20%的折扣

我的分页是每个帖子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:

我想每页显示10条帖子, 目前每页显示12条带有粘性帖子的帖子。

这个问题是针对硕士而不是针对新学习者的。

这里有人高手吗?提前致谢

正如我在评论中建议的那样, 将”粘性帖子”保存在meta中(假设is_featured_post作为”元密钥”)。

仅运行一次以设置现有帖子的元值。你可以跳过此步骤, 因为你已经保存了元数据。

// 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'  );
    }
}

每次更新帖子(或保存新帖子)时, 以下函数都会更新新的粘性元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操作设置类别查询。我们按”元”和”日期”降序排列以在顶部显示最新的。

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' );

如果要随机化非粘性帖子, 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;
}

下面的功能将便利贴推到顶部, 你应该可以使用此功能为你提供帮助。

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);
}
