首先，值得注意的是，您不是在进行PHP查询，而是在使用WordPress函数（update_post_meta）来保存这些数据。这可能是混淆的地方
您遇到的问题是您正在传递数据。在WordPress中，即使它将数据作为序列化数据存储在数据库中，您也不必自己进行序列化/取消序列化
WordPress“自动”存储序列化的数据。这意味着当你调用时，你只需传入你试图保存的数组
这是基于上述代码的一个简单示例：

$data = array( array( 'type' => 'blocks', 'cost' => NULL, 'modifier' => NULL, 'base_cost' => 0.027, 'base_modifier] => 'times', 'from' => 1, 'to' => 3 ), array( 'type' => 'blocks', 'cost' => NULL, 'modifier' => NULL, 'base_cost' => 0.02914814815, 'base_modifier] => 'times', 'from] => 4, 'to] => 4 ) ); update_post_meta( $product_id, '_wc_booking_pricing', $data );

然后，当您使用检索数据时，它将以数组的形式返回数据，与您保存的数据完全相同。

您试图传递的字符串是序列化数据，需要首先取消序列化
两种可能的情况：
1）如果已经序列化了该数据，请不要这样做，而是直接在
update\u post\u meta（）

请注意，在使用
update\u post\u meta（）
时，“传递的数组将序列化为字符串”，因此在您的情况下，要避免一种双重序列化，这种双重序列化会使数据无法读取
2）如果您自己没有序列化该数据，您可能需要先取消序列化该数据。为此，您可以在使用

现在，您的数据已正确保存在数据库中，并且可以读取和/或处理。
我不知道您在做什么，但我的直觉告诉我您做错了！确实，您做错了。不要先自己序列化数据，而是调用
update\u post\u meta
并传入您想要的数组/对象/字符串ave.WP自动序列化。然后，当您使用
get\u post\u meta
时，WP会自动取消序列化。双重序列化的原因是WP中的安全修复程序试图避免反序列化不受信任的数据。您可能应该遵循指导您让WP处理序列化的注释/答案，而不是手动执行。I我不知道你在做什么，但我的直觉告诉我你做错了！事实上，你做错了。不要先自己序列化数据-而是调用
