我想获得从ID的 [范围] = stdClass的对象

推荐答案

正如你可能会看到，你的产品对象有一个属性 range_id ：

As you might see, your Product object has an attribute range_id:

Product Object
(
    [name] => Simon Test Cup
    [code] => 123456789
    [category_id] => 3
    [range_id] => 26          // <--- here!
    [price] => 10.00
    ...

所以，你应该能够通过拿到ID：

So you should be able to get the ID via:

$object->range_id

---

但也许，在产品和范围类定义，使您能够访问这些信息的方法，你应该使用他们，而不是。你只需要阅读文档如何使用它们。

---

But probably, the Product and Range classes define methods that allow you to access those information and you should use them instead. You just have to read the documentation how to use them.
