wordpress 自定义 post 类型元字段值

Question

我在 wordpress 中有以下来自自定义 post 类型的多维数组。自定义 post 类型名称是：“references”

如何获得以下值：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"
  }

感谢您的帮助！

Answer 1

数据已序列化，因此您需要对其进行反序列化。

Reference to unserialize

$result = unserialize($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"];
