Invalid argument supplied for foreach

[Yohanne]

hello coders.

 

what is the possible reason why i get this warning:   Invalid argument supplied for foreach() in

 and i have no idea behind this code, but i know there is someone else can read this and understand behind the logic. 

$orders = Order::getOrdersWithInformations(10);
$i = 0;
foreach($orders AS $order)
{
      $currency = Currency::getCurrency((int)$order['id_currency']);
	echo '
	<tr'.($i % 2 ? ' id="order_line1"' : '').'>
	<td class="order_td_first order_id">'.(int)$order['id_order'].'</td>
	<td class="order_customer">'.Tools::htmlentitiesUTF8($order['firstname']).' '.Tools::htmlentitiesUTF8($order['lastname']).'</td>
	<td class="order_status">'.Tools::htmlentitiesUTF8($order['state_name']).'</td>
	<td class="order_total">'.Tools::displayPrice((float)$order['total_paid'], $currency).'</td>
	<td class="order_action">
	<a href="index.php?tab=AdminOrders&id_order='.(int)$order['id_order'].'&vieworder&token='.Tools::getAdminTokenLite('AdminOrders').'" title="'.$this->l('Details').'"><img src="../img/admin/details.gif" alt="'.$this->l('See').'" /></a>
			</td>
			</tr>
				';
			$i++;
		}

Because $orders is not an array (or other iterable object). Check that getOrdersWithInformation().

[applebiz89]

If your not sure of the output of the result for getOrdersWithInformation() - wrap a conditional statement around your foreach, checking that the result of getOrdersWithInformation() is an array, so the foreach loop isn't instantiated and causing any errors if the result is false...

Show us the output var_dump function  will  print:

$orders = ...
var_dump($orders);

Post your getOrdersWithInformations() method. Is there a reason it's static?
