没有插件，所以我写了一个。您可以将其用作插件或（更好）mu插件（将其放置在~/wp-content/mu-plugins 文件夹）。

Mu插件：通过删除MetaBox来延迟“发布帖子”的可能性。有关发生的情况和原因的详细说明，请参阅内联评论：

// Only run this for new "post"-post_type admin UI screens
if ( ! is_admin() AND \'post-new.php\' !== $GLOBALS[\'typenow\'] ) return;

function remove_publish_metabox_until_date() 
{
    // Retrieve the current users\' data as object
    $curr_user = get_user_by( \'id\', get_current_user_id() );

    // Get the time/date (and format) of the time 
    // the user registered as UNIX timestamp - needed for comparison
    $reg_date  = abs( strtotime( $curr_user->user_registered ) );
    $curr_date = abs( strtotime( current_time( \'mysql\' ) ) );

    // Human readable difference: This calculates the time since the user registered
    $diff       = human_time_diff( $reg_date, $curr_date );
    $diff_array = explode( \' \', $diff );

    // Remove if we\'re on the 1st day (diff result is mins/hours)
    // This removes the MetaBox
    if ( 
        strstr( $diff_array[1], \'mins\' )
        OR strstr( $diff_array[1], \'hours\' )
    )
        return remove_meta_box( \'submitdiv\', null, \'side\' );

    // Remove if we\'re below or equal to 7 days (1 week)
    // This removes the MetaBox
    if ( 7 >= $diff_array[0] )
        return remove_meta_box( \'submitdiv\', null, \'side\' );
}
add_action( \'add_meta_boxes\', \'remove_publish_metabox_until_date\', 20 );
