WordPress:Function Reference/get post custom values

描述

Returns an array containing all the values of the custom fields with a particular key ($key) of a particular post ($post_id). Returns nothing if no such key exists, or none is entered. See also get_post_custom() and get_post_custom_keys().

返回一个数组，包含某篇文章($post_id)某关键字($key)自定义fields的所有参数值。如果不存在这样的关键字，或者没有输入任何内容，不返回任何内容。也看看get_post_custom() 和get_post_custom_keys()。

%%% <?php get_post_custom_values($key, $post_id); ?> %%%

%%% <?php get_post_custom_values($key, $post_id); ?> %%%

例子

默认用法

The following example sets a variable ($mykey_values) as an array containing the values of the custom fields of the current post with the key my_key.

<?php

下面的例子将一个变数(<tt>$mykey_values</tt>)设置为一个数组，包含关键字为''my_key''的当前文章的自定义fields的参数值。
<pre><?php

  $mykey_values = get_post_custom_values('my_key');
  foreach ( $mykey_values as $key => $value ) {
    echo $key . " => " . $value . "<br />"; 
  }

?>

0 => First value with "my_key" as its key
1 => Second value with "my_key" as its key
2 => Third value with "my_key" as its key
etc...

 $mykey_values = get_post_custom_values('my_key');
 foreach ( $mykey_values as $key => $value ) {
   echo $key . " => " . $value . "
"; 
 }

?>

0 => First value with "my_key" as its key
