我没有离开任何expired 发布状态，但您可以将发布状态设置为draft 属于trash.

首先，您需要设置一个cron作业以每隔一段时间运行一次，并检查日期是否已到。找到合适的时间取决于你。

// Let\'s check the scheduled even on WP load
add_action( \'init\', \'schedule_post_expiration\' );
function schedule_post_expiration() {

    // If the even is not scheduled already, then do schedule it
    if ( ! wp_next_scheduled( \'reset-post-status\' ) ) {
        wp_schedule_event( strtotime( \'00:00:00\' ), \'daily\', \'reset-post-status\' );
    }

}

// We hook our callback function to our custom action hook to run
// daily and update the post\'s status
add_action( \'reset-post-status\', \'reset_post_status_callback\' );
function reset_post_status_callback(){

    // Get the current date
    $date = date( \'Y-m-d\' );

    // Set the date we want to check. It should match the above date format.
    $check_date = \'2018-02-11\';

    // Check if the time has come
    if ( strtotime( $date ) > strtotime( $check_date ) ){

        // Query a list of a specific author\'s posts
        $author_args = array( \'author\' => 123, \'post_status\' => \'publish\' );

        // Do the query
        $author_query = new WP_Query( $author_args );

        // Check if the query has any post, and setup the post data
        if ( $author_query->have_posts() ) {
            while ( $author_query->have_posts() {
                $author_query->the_post();

                // Update the post\'s status
                wp_update_post( array( \'ID\' => get_the_ID(), \'post_status\' => \'trash\' ) );

            }
        }
        // Reset the posts data
        wp_reset_postdata();
    }

}
