在编辑页面时提取已保存到post\\u meta的数字数据（数字）时-例如：

$number = get_post_meta( $post->ID, \'number\', true ); 

然后在meta\\u查询中将该值与get\\u posts一起使用-例如：

$args = array (
    \'posts_per_page\'    => 4, // limit ##
    \'post_type\'         => \'post\',
    \'post__not_in\'      => array ( $post->ID ), // exclude self ##
    \'meta_query\'        => array (
        array (
            \'key\'       => \'related_page\',
            \'value\'     => $number,
        )
    ),
);

$posts = get_posts( $args );

我们是否首先需要键入juggle将检索到的值变为整数，因为它似乎是作为字符串返回的：

var_dump($args) 提供：

array(5) {
  ["posts_per_page"]=>
  int(4)
  ["post_type"]=>
  string(4) "post"
  ["post__not_in"]=>
  array(1) {
    [0]=>
    int(1387)
  }
  ["meta_query"]=>
  array(3) {
    [0]=>
    array(2) {
      ["key"]=>
      string(15) "related_page"
      ["value"]=>
      string(1) "10"
    }

  }
}

我应该使用其他custom field “比较”或“类型”等设置？

$args = array (
    \'post_type\'         => \'post\',
    \'meta_query\'        => array (
        array (
            \'key\'       => \'related_page\',
            \'value\'     => 1,
        )
    ),
);

$posts = new WP_Query( $args );
var_dump($posts->request);

update_post_meta(1,\'hal9000\',1);
var_dump(get_post_meta(1,\'hal9000\'));

$query_args[\'meta_query\'][] = array(
  \'key\' => \'your_key_which_is_a_number\',
  \'value\' => array(intval($minimum), intval($maximum)),
  \'compare\' => \'BETWEEN\',
  \'type\' => \'NUMERIC\'
 );
