自定义栏目可以为我们的文章和页面增加一些额外的元数据,但这些元数据只能在循环内部(Loop)显示,在循环(Loop)外部是看不到的。由于wordpress的所有数据都存储在MySQL数据库中,所以我们可以通过MySQL的查询来获取循环之外的文章自定义栏目值。这会是一个很有用的wordpress技巧。方法如下:

添加如下代码到wordpress主题的任意位置:
- <?php
- global $wp_query;
- $postid = $wp_query->post->ID;
- echo get_post_meta($postid, 'CUSTOM-FIELD-NAME', true);
- ?>
只需替换“CUSTOM-FIELD-NAME”为你的自定义栏目名称即可。
