Question

I’m wondering how can I add attributes, that are not declared in a class, into an object.

Let me explain :

I have my order :

 [0] => stdClass Object
( 
   [quantityBlack] => 3
   [quantityBlue] => 1
   [quantityGreen] => 0
   [quantityOrange] => 0
   [quantityPurple] => 0
   [quantityRed] => 0
   [dateOfOrder] => Fri, 06 Jul 12 22:21
   [user_id] => 5
   [comments] => Test
)

and I would like to replace the user_id by the attributes of the user,

so what I would like to do is :

foreach ($data['orders'] as $key => $order){

        $data['orders']->$key???-> = $this->user_model->GetUsers(array('userId' => $order->user_id));

    }

but I don’t know how to specifically target a single object (you see the key???) at the end, I would like to get the attributes of the related user to that order.

How can I do that ?

Thank You !

If I understand correctly your data structure you are seeking to do the following:

foreach($data['orders'] as $key => $order) {
    $data['orders'][$key]->user = $this->user_model->GetUsers(array('userId' => $data['orders'][$key]->user_id));
    unset($data['orders'][$key]->user_id);
}

I’m assuming $data[‘orders’] is an array containing a bunch of stdClass objects like the one referenced in the question, hence why in this case you would use the $data[‘orders’][$key] syntax to access each array element first before accessing the properties of each object.

Note that both the data structure and your intent in the question are a bit unclear though, so if this doesn’t address your question you may want to give more context.
