这是我现在如何从自定义帖子类型中获取图像的一个示例，使用query_posts();

// query_posts stuff made up here.
$my_array = get_custom_field(\'image:to_array\', \'to_image_array\'); 
// $my_array is now all my images from that post.

我要做的是使用get\\u nextigation\\u post（）从自定义post类型中拉出一个图像。当我打印出相邻帖子的信息时，我看不到任何有助于从此帖子类型中提取图像的内容。这是相邻帖子的打印内容。

有没有办法用这种方式拉出我的自定义帖子类型的图片？

$value = get_post_meta($post->ID,\'key name\',true); // where true indicates there is only a single key value pair of \'key name\'

global $wp_query;

$postid = $wp_query->post->ID;

echo get_post_meta($postid, \'key\', true);
