wordpress自定义文章类型元字段值 - wordpress custom post type meta field value

wordpress custom post type meta field value

我在自定义post类型的wordpress中有以下多维数组。自定义帖子类型名称为："引用"

如何获取以下值：reference_page_lead和reference_page_url？

array(4) {
  ["_edit_last"]=>
  array(1) {
    [0]=>
    string(1) "1"
  }
  ["_edit_lock"]=>
  array(1) {
    [0]=>
    string(12) "1424697906:1"
  }
  ["_reference"]=>
  array(1) {
    [0]=>
    string(189) "a:2:{s:19:"reference_page_lead";s:95:"A Lorem Ipsum egy egyszerû szövegrészlete, szövegutánzata a betûszedõ és nyomdaiparnak.";s:18:"reference_page_url";s:19:"https://lorem.ipsum";}"
  }
  ["_thumbnail_id"]=>
  array(1) {
    [0]=>
    string(2) "36"
  }

谢谢你的帮助！

数据是序列化的，因此需要取消序列化。

取消序列化的参考

$result = unserialize($theArray["_reference"][0]);
echo $result['reference_page_url'];
echo $result['reference_page_lead'];

谢谢，我解决了：

        $reference_data = get_post_meta( $post->ID, '_reference', true );
        echo "<pre>";
        var_dump($reference_data);
        echo "</pre>";
        foreach ( $reference_data as $key => $value ) {
            echo "<pre>";
            echo $key . " => " . $value . "<br />";
            echo "</pre>";
        }
       $reference_data["reference_page_lead"];
       $reference_data["reference_page_url"];
