I am wanting to get the id from the [range] = stdClass Object

Answer 1

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
    ...

So you should be able to get the ID via:

$object->range_id

---

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.

Answer 2

$product->_related["_related"]["range"]->key

But i'm not sure that i've understood well

Answer 3

You could say $object->_related["_related"]["range"], but this structure is presumably that of an object which has accessors for things you might want from it. You're clearly not intended to worry about the internal structure of the thing.

Answer 4

Assuming Felix' answer doesn't work (which it may very well), I'm guessing that the _related field is protected. In that case, there should be an accessor method in that class to let you get related objects. Please use get_class_methods() on the object and edit your post with the methods that are available.
