The two arrays made with find() look like I would expect them to, but
the foreach loop leaves $discount_prices (of which many have null
values) unaffected. What am I missing here?
//get regular prices
$item_prices = $this->Item->find('list', array('fields' =>
array('Item.price')));
//see if there are any discounts prices for the week's items
$discount_prices = $this->Order->Week->WeeksItem-
>find('list',
array('fields'=>array('item_id','discount_price'),
'conditions'=>array('week_id'=>$week_id)));
//if there is no discount price (value is null), add the regular price
foreach($discount_prices as $key => $discount_price){
if(!isset($discount_price)) $discount_price =
$item_prices[$key];
}
