%%% <?php get_post_custom($post_id); ?> %%%

例子

默认用法

Use the following example to set a variable ($custom_fields) as a multidimensional array containing all custom fields of the current post.

<?php $custom_fields = get_post_custom(); ?>

使用下面的例子，设置一个变数($custom_fields)作为多维数组，包含当前文章所有的自定义field。 <?php $custom_fields = get_post_custom(); ?>

得到数组中的数据

The following example will retrieve all custom field values with the key my_custom_field from the post with the ID 72 (assuming there are three custom fields with this key, and the values are "dogs", "47" and "This is another value").

下面的例子会返回ID是72的文章，关键字为my_custom_field的所有自定义field参数值（既然这个关键词拥有三个自定义field，参数值分别是"狗""47"和 "这是另一个参数值"）。

<?php

  $custom_fields = get_post_custom();
  $my_custom_field = $custom_fields['my_custom_field'];
  foreach ( $my_custom_field as $key => $value )
    echo $key . " => " . $value . "<br />";

?>

0 => dogs
1 => 47
2 => This is another value

<?php

  $custom_fields = get_post_custom();
  $my_custom_field = $custom_fields['my_custom_field'];
  foreach ( $my_custom_field as $key => $value )
    echo $key . " => " . $value . "<br />";

?>

0 =>狗
1 => 47
2 => 这是另一个参数值
