Question

我刚刚使用wptuts的教程创建了一种长元数据集，但我迷失了两件事：

元数据的输出显示所有分组的数据（例如，在分组复选框中，即使我有不同的组，它们也是一个整体），我想抓住每个组的标题并显示在不同的表格，div或块。
不知道如何在帖子中显示已保存的数据，也将其显示在不同的块中。

我的代码是：

<?php

$prefix = 'dbt_';

Answer 1

$some_var = get_post_meta($post->ID, 'name_of_post_meta_data_here', true);

echo $some_var;

这有帮助吗？阅读马克发布的链接。

修改

$some_var

给它一个名字，比如$ currency，$ address ......这可以是你想要的。

get_post_meta($post->ID),

这意味着它从当前帖子中获取元数据。

'name_of_post_meta_data_here', true);

这是您在变量中放置所需内容的位置，因此您创建了自定义元框。的确如此，它为数组输出一个字符串false。

而且你可以像以下一样回应：

<?php echo $some_var; ?>

我认为您应该查看Advanced Custom Fields或Pods Framework，它们可以完全按照您的要求进行操作，而您需要较少的PHP知识来处理它。我不是PHP英雄所以我可以联系=）

如何在wordpress元数据中分离数据？
