30天后丢弃自定义帖子类型

为此,我从@pieter goosen那里找到了一个很好的解决方案,可以在几天后删除帖子: https://wordpress.stackexchange.com/questions/209046/delete-expired-posts-after-a-number-of-days-after-they-expired

我的问题是,该函数删除此自定义帖子类型的所有帖子,并且不使用垃圾桶。

我的代码如下所示:

function get_exired_posts_to_delete()
{
    /**
     * If you need posts that expired more than a week ago, we would need to
     * get the unix time stamp of the day a week ago. You can adjust the relative
     * date and time formats as needed.
     * @see http://php.net/manual/en/function.strtotime.php
     * @see http://php.net/manual/en/datetime.formats.php
     */
    // As example, we need to get posts that has expired more than 7days ago
    $past = strtotime( "- 1 week" );

    // Set our query arguments
    $args = [
        'fields'         => 'ids', // Only get post ID's to improve performance
        'post_type'      => 'job',
        'post_status'    => 'publish',
        'posts_per_page' => -1,
        'date_query'    => array(
            'column'  => 'post_date_gmt',
            'before'   => '30 days'
        )
    ];
    $q = get_posts( $args );

    // Check if we have posts to delete, if not, return false
    if ( !$q )
        return false;

    // OK, we have posts to delete, lets delete them
    foreach ( $q as $id )
        wp_delete_post( $id );
}

// expired_post_delete hook fires when the Cron is executed
add_action( 'expired_post_delete', 'get_exired_posts_to_delete' );

// Add function to register event to wp
add_action( 'wp', 'register_daily_post_delete_event');
function register_daily_post_delete_event() {
    // Make sure this event hasn't been scheduled
    if( !wp_next_scheduled( 'expired_post_delete' ) ) {
        // Schedule the event
        wp_schedule_event( time(), 'daily', 'expired_post_delete' );
    }
}

有没有更好的解决方案来使用服务器cron而不是WP cron?
