The code for products.php is as follows.

<?php

?>
<?php get_header(); ?>
<div id="content" class="narrowcolumn">
   <?php $recent = new WP_Query("cat=4&showposts=10"); while($recent->have_posts()) :$recent->the_post();?>
   <?php $key_values = get_post_custom_values("Description"); ?>
   <?php foreach($key_values as $key => $value )?>
   <?php echo  "$key  => $value("Description") <br />";?>
   <?php endwhile; ?>

get_post_custom_values()如果键不存在，则返回null 。参考：wp-includes/.post.php:1892

您可以将返回的值转换为数组，以确保您始终在处理数组并避免该警告：

<?php $key_values = (array) get_post_custom_values("Description"); ?>

为什么不使用get_post_meta？我在我的网站上使用它，它按预期工作。
