我正在尝试显示上周最受欢迎的帖子。然而，我认为它工作不正常，显示了最受欢迎（浏览量最大）的帖子。我知道我的代码是有效的，因为我可以使用monthnum“=>$month查看上个月最受欢迎的帖子。如何修复此问题以显示上周最受欢迎的帖子？

<?php 
$week = date(\'W\'); 
$year = date(\'Y\'); 
$new_query = new WP_Query( array(\'posts_per_page\' => 1, \'cat\' => 14, \'meta_key\' => \'wpb_post_views_count\', \'orderby\' => \'meta_value_num\', \'order\' => \'DESC\',\'weeknummer\'=>$week,\'year\'=>$year )); 
?> 
<?php if ( $new_query->have_posts() ) : ?> 
<?php while ( $new_query->have_posts() ) : $new_query->the_post(); ?> 
<?php the_title(); ?>
<?php endwhile; wp_reset_postdata(); ?> 
<?php else : ?> 
<?php endif; ?> 

// Popular Posts
function wpb_set_post_views($postID) { 
$count_key = \'wpb_post_views_count\'; 
$count = get_post_meta($postID, $count_key, true); 
if($count==\'\'){ 
$count = 0; 
delete_post_meta($postID, $count_key); 
add_post_meta($postID, $count_key, 0); 
}else{ 
$count++; 
update_post_meta($postID, $count_key, $count); 
} 
} 
//To keep the count accurate, lets get rid of prefetching 
remove_action( \'wp_head\', \'adjacent_posts_rel_link_wp_head\', 10, 0);

function wpb_track_post_views ($post_id) { 
if ( !is_single() ) return; 
if ( empty ( $post_id) ) { 
global $post; 
$post_id = $post->ID; 
} 
wpb_set_post_views($post_id); 
} 
add_action( \'wp_head\', \'wpb_track_post_views\');
