如何在页面

好,您正在使用:

 get_post_meta(get_the_ID(), 'subtitle', TRUE);
 

因此,您对Wordpress说要获取"字幕"字段的元值,并且返回的值应为字符串格式.参见get_post_meta()文档.

要获取帖子的所有元数据,您应该改用get_post_custom()函数.例如,如果您在循环中:

 $custom = get_post_custom();
foreach($custom as $key => $value) {
     echo $key.': '.$value.'<br />';
}
 

这将返回帖子的所有元数据.例如,如果您要检查"价格"元字段:

 if(isset($custom['price'])) {
    echo 'Price: '.$custom['price'][0];
}
 

Well, you are using:

get_post_meta(get_the_ID(), 'subtitle', TRUE);

So, you are saying to Wordpress to get the meta value of the 'subtitle' field and that the returned value be in format of string. See get_post_meta() docu.

To get all meta data of a post you should use get_post_custom() function instead. For example, if you are inside the loop:

$custom = get_post_custom();
foreach($custom as $key => $value) {
     echo $key.': '.$value.'<br />';
}

This will return all meta data of the post. If you want to check, for example, the "price" meta field:

if(isset($custom['price'])) {
    echo 'Price: '.$custom['price'][0];
}

使用此代码解决您的问题.

 $key_name = get_post_custom_values($key = 'Key Name');
echo $key_name[0];
 

use this code for solving your problem.

$key_name = get_post_custom_values($key = 'Key Name');
echo $key_name[0];
