总而言之，我正在创建一个自定义WP Schedule事件，每天检查一次，看看我的；“成员”；自定义帖子类型的帖子被标记为粘滞，如果是，则将其从粘滞帖子选项表中删除，然后随机分配另一个成员帖子作为粘滞帖子。（我在主页上通过一个短代码显示这篇随机帖子，这里没有显示短代码）。

我想我在这方面取得了一些进展。我的代码中有一些错误，我在下面强调了这些错误，例如变量名称错误和缺少开头if语句。

我不得不放弃按字母顺序显示这些帖子，因为我不知道如何编码，所以我决定按随机顺序。我在orderby rand中添加了php会话功能，这样每个网站访问者就不会看到同一篇文章两次，尽管我不能完全确定这是否可行。

以下是我在本帖帮助下的查询：https://wordpress.stackexchange.com/a/217080/199183

    <?php 


$stickies = get_option( \'sticky_posts\' );
// Make sure we have stickies to avoid unexpected output
if ( $stickies ) {
    $args = [
        \'post_type\'           => \'member\',
        \'post__in\'            => $stickies,
        \'posts_per_page\'      => 1,
        \'ignore_sticky_posts\' => 1
    ];
    $the_query = new WP_Query($args);

    if ( $the_query->have_posts() ) { 
        while ( $the_query->have_posts() ) { 
            $the_query->the_post(); ?>

                   <div class="daily-member-header">

        wp_reset_postdata();

} ?>

以下是本帖帮助下的完整功能-https://wordpress.stackexchange.com/a/325554/199183 （对于计划功能和本页-https://love-coding.pl/en/wordpress-how-to-display-random-posts-without-duplicates/ （对于会话功能）：

function prefix_start_session() {
    if( !session_id() ) {
        session_start();
    }
}
add_action( \'init\', \'prefix_start_session\' );

function get_random_post() {
    if ( !isset( $_SESSION[\'random\'] ) ) {
        $_SESSION[\'random\'] = rand();
    }
    return $_SESSION[\'random\'];
}

function wi_custom_cron_schedule( $schedules ) {
    $schedules[\'5min\'] = array(
        \'interval\' => 5, // Every 5 minutes
        \'display\'  => __( \'Every 5 Minutes\' ),
    );
    return $schedules;
}
add_filter( \'cron_schedules\', \'wi_custom_cron_schedule\' );

    if (! wp_next_scheduled ( \'mark_posts_as_featured_event\' )) {
        wp_schedule_event(time(), \'5min\', \'mark_posts_as_featured_event\');
    }

add_action( \'mark_posts_as_featured_event\', \'mark_posts_as_featured_event_callback\' );

function mark_posts_as_featured_event_callback() {
    // if there are sticky posts in our CPT, unstick them
    $sticked_post_ids = get_option( \'sticky_posts\' );
    if ( ! empty($sticked_post_ids) ) { 
        $old_featured_posts = get_posts( array(
            \'post_type\' => \'member\',
            \'fields\' => \'ids\',
            \'post__in\' => $sticked_post_ids,
        ) );

        foreach ( $old_featured_posts as $post_id ) {
            unstick_post( $post_id );
        }
    }

    // stick new posts
    // get_random_posts
    $new_featured_posts = get_posts( array(
        \'post_type\' => \'member\',
        \'posts_per_page\' => 1,
        \'orderby\' => \'rand(\' . get_random_post() . \')\',
        \'fields\' => \'ids\',
    ) );

    foreach ( $new_featured_posts as $post_id ) {
        stick_post( $post_id );
    } 
}

Errors fixed

在前面的代码中，我意识到我需要更改：

foreach ( $old_featured_post_ids as $post_id ) {

致：

foreach ( $old_featured_posts as $post_id ) {

还意识到我错过了开场白if语句。

旧版本：

function mark_posts_as_featured_event_callback() {
    // if there are sticky posts in our CPT, unstick them
    $sticked_post_ids = get_option( \'sticky_posts\' );
        $old_featured_posts = get_posts( array(
            \'post_type\' => \'member\',
            \'fields\' => \'ids\',
            \'post__in\' => $sticked_post_ids,
        ) );

        foreach ( $old_featured_post_ids as $post_id ) {
            unstick_post( $post_id );
        }
    }

新建：

function mark_posts_as_featured_event_callback() {
    // if there are sticky posts in our CPT, unstick them
    $sticked_post_ids = get_option( \'sticky_posts\' );
    if ( ! empty($sticked_post_ids) ) { 
        $old_featured_posts = get_posts( array(
            \'post_type\' => \'member\',
            \'fields\' => \'ids\',
            \'post__in\' => $sticked_post_ids,
        ) );

        foreach ( $old_featured_posts as $post_id ) {
            unstick_post( $post_id );
        }
    }

一

foreach ( $old_featured_post_ids as $post_id ) {
 并更改了“orderby-=>；”rand\'，至“orderby”=>；\'rand（\'.get\\u random\\u post（）.\'）\'，使用新会话代码。
