默认的Paypal支付模块付款并没有把产品名称POST到Paypal，

让人在Paypal付款界面和后台查看一头雾水，看不出是买了什么。

轻微改一下。【还不知道系统有没有更好的解决方法，对zen-cart不太熟】

paypal.php 页

将： 
$optionsAggregate = array( 
‘cmd’ => ‘_ext-enter’, 
‘item_name’ => MODULE_PAYMENT_PAYPAL_PURCHASE_DESCRIPTION_TITLE,
‘item_number’ => MODULE_PAYMENT_PAYPAL_PURCHASE_DESCRIPTION_ITEMNUM, 
//’num_cart_items’ => sizeof($order->products), 
‘amount’ => number_format($this->transaction_amount, $currencies->get_decimal_places($my_currency)), 
’shipping’ => ‘0.00′, 
);

改为：   
for ($i=0, $n=sizeof($order->products), $k=1; $i<$n; $i++, $k++) { 
$product_names =$product_names . $order->products[$i]['name'] . ” ; “; 
}//列出订单中的所有产品名称 
$optionsAggregate = array( 
‘cmd’ => ‘_ext-enter’, 
‘item_name’ =>MODULE_PAYMENT_PAYPAL_PURCHASE_DESCRIPTION_TITLE, 
‘item_number’ => $product_names,//MODULE_PAYMENT_PAYPAL_PURCHASE_DESCRIPTION_ITEMNUM,
//’num_cart_items’ => sizeof($order->products), 
‘amount’ => number_format($this->transaction_amount, $currencies->get_decimal_places($my_currency)), 
’shipping’ => ‘0.00′, 
);
