从Magento集合中提取数据。 我将它分解为一个数组，但试图调用它打破了页面

Question

I'm working on a script that will give a Magento user directions after selecting warehouse pickup (a plugin option). I already have the rest built. I'm simply missing one variable I need to call on success.phtml (the warehouse ID). The variable is tied to orders via stock_id.

This produces an array: I'm using $order successfully to pull the rest of the info I need for the script.

$order = Mage::getModel('sales/order')->loadByIncrementId($this->getOrderId());
$items = $order->getItemsCollection();

A shortened version of this array: can be printed with print_r($items->getData());

Array
(
    [0] => Array
        (
            [item_id] => 223
            [stock_id] => 15
            [base_discount_refunded] => 
        )

)

When I try to pull the data that I want out:

echo $items[0]['stock_id']; //the page breaks here and stops the page abruptly... 

the page breaks and any logic that should take place after is ignored. What would cause this? I tried braking variables I'm calling in other similar arrays. None of my tests have replicated the page breaking. Why is this specific one breaking the page instead of returning 15?

You might try enumerating $items using var_export in your page, instead of print_r so you can see them as they truly exist:

foreach ($items as $item)
{
   var_export($item->debug());
}

This will provide you with the results. Items is an object populated with more objects, not an array and should be treated as such. Try using

$itemId = $item->getStockId();

or

$itemId = $item->getData('stock_id');

Both accomplish the same thing.

FYI.. the debug() function shows relevant info and its built into magento for use with all mage objects.

EDIT: Try this:

echo $items[0]->getData('stock_id');
