Question

I am attempting sort this array by each stdClass Object’s [title] in an Ubercart order.tpl.php file. I have tried doing just a normal sort but since they all are stdClass Objects it doesn’t do anything.

<pre>Array
(
[0] => stdClass Object
    (
        [order_product_id] => 1157
        [order_id] => 142
        [nid] => 38
        [title] => Eatonville Forest Camping Permit
        [manufacturer] => 
        [model] => eatonville-camp-permit
        [qty] => 1
        [cost] => 9.00000
        [price] => 10.00000
        [weight] => 0
        [data] => Array
            (
                [attributes] => Array
                    (
                    )

                [shippable] => 0
                [restrict_qty] => 1
                [module] => uc_product
            )

        [order_uid] => 13
    )

            )

        [order_uid] => 13
    )
)</pre>

This is the code controlling it in the order.tpl.php

<pre>php if (is_array($order->products)) {
                        $context = array(
                          'revision' => 'formatted',
                          'type' => 'order_product',
                          'subject' => array(
                           'order' => $order,
                          ),
                        );
}
</pre>

Answer 1

I think usort() should work:

function sortByTitle($a, $b){
  return strcmp($a->title, $b->title);
}

usort($theArray, 'sortByTitle');

You may want to throw in some checking to make sure the title member actually exists.
