WordPress 自定义过期时间

Question

我的代码功能有问题。自定义帖子应在一定天数后过期。目前设置为 3 天，以便我进行测试。

但是即使过期日期早于今天的日期，帖子也会过期，我不知道为什么？！

// Setup Cron Job Function to expire posts and send out emails.
function listing_expiry_date() {

    // Get the current date
    date_default_timezone_set('Europe/London');
    $today = date('m/d/Y');
                            
    // Custom Post Type for listings, grab published posts
    $args = array(
        'post_type'      => array( 'post_type_listings' ),
        'post_status'    => array( 'Publish' ),
        'posts_per_page' => -1,
    );
    
    // The Query
    $query = new WP_Query( $args );
    
    // The Loop
    if ( $query->have_posts() ) :
        while ( $query->have_posts() ) :
            $query->the_post();
            
            // Get the listing ID
            $post_id = get_the_ID();
                
    // Get listing post published date (not pending date)    
    $published_date = get_the_date( 'm/d/Y', get_the_ID() );
    
                                                    
        $expiry_date  = date( 'm/d/Y', strtotime( '+3 days', strtotime($published_date) ) );        
            
        // If todays date is equal to or greater than the expiry date...
        if ( ($today == $expiry_date) || ($today > $expiry_date) ) :

    // change post status to 'expired'
    $postdata = array(
    'ID'          => $post_id,
    'post_status' => 'expired',

        );

    // Update post data
    wp_update_post($postdata);
                                                                                
    endif;                          
            
    endwhile; //endwhile The Loop
endif; //endif The Loop         
    
}

您的问题似乎是您如何评估日期。在这种情况下，最好使用 Unix 时间戳来评估哪个更大。

function listing_expiry_date() {

    // Get the current date.
    date_default_timezone_set( 'Europe/London' );
    $today = date( 'U' );

    // Custom Post Type for listings, grab published posts.
    $args = array(
            'post_type'      => array( 'post_type_listings' ),
            'post_status'    => array( 'publish' ),
            'posts_per_page' => -1,
    );
    // The Query.
    $query = new WP_Query( $args );

    // The Loop.
    if ( $query->have_posts() ) :
        while ( $query->have_posts() ) :
            $query->the_post();

            // Get the listing ID.
            $post_id = get_the_ID();

            $expiry_date = date( 'U', strtotime( '+3 days', get_the_date( 'U', $post_id ) ) );
            // If Expiration date is < or = today.
            if ( $expiry_date <= $today ) :
                // change post status to 'expired'
                $postdata = array(
                        'ID'          => $post_id,
                        'post_status' => 'expired',

                );

                // Update post data.
                wp_update_post($postdata);

            endif;

        endwhile; // endwhile The Loop.
    endif; // endif The Loop.

}
