我一直在努力申请Drupal商业优惠券约2天。我已经负责验证优惠券,并且在我试图兑换优惠券时感到难过。
所以在我的回调函数中我正在调用:
my_module_coupons_coupon_redeem($coupon);
在兑换功能中,我有:
function my_module_coupons_coupon_redeem($coupon) {
global $user;
$uid = $user->uid;
$order = commerce_cart_order_load($uid);
// Wrap the order for easy access to field data.
$order_wrapper = entity_metadata_wrapper('commerce_order', $order);
// Create the new line item.
$line_item = commerce_coupon_line_item_new($coupon, $order->order_id);
$line_item->commerce_unit_price = array('und' => array(
'0' => array('amount' => 500, 'currency_code' => commerce_default_currency())
));
$line_item_wrapper = entity_metadata_wrapper('commerce_line_item', $line_item);
if (!is_null($line_item_wrapper->commerce_unit_price->value())) {
// Add the base price to the components array.
if (!commerce_price_component_load($line_item_wrapper->commerce_unit_price->value(), 'base_price')) {
$line_item_wrapper->commerce_unit_price->data = commerce_price_component_add(
$line_item_wrapper->commerce_unit_price->value(),
'base_price',
$line_item_wrapper->commerce_unit_price->value(),
TRUE
);
}
}
$line_item_wrapper->commerce_total->data = $line_item_wrapper->commerce_unit_price->data;
//$line_item_wrapper->commerce_product->data = $coupon;
// Save the line item now so we get its ID.
commerce_line_item_save($line_item);
// Add it to the order's line item reference value.
$order_wrapper->commerce_line_items[] = $line_item;
commerce_order_save($order);
}
优惠券line_item正在保存在数据库中,但是当我刷新购物车页面时,我收到以下错误:
EntityMetadataWrapperException: Unknown data property commerce_product. in EntityStructureWrapper->getPropertyInfo()
只是想知道这是否是在不使用规则的情况下应用优惠券的正确方法,我是否应该首先将其保存为订单项?

查看sites / all / modules / commerce_coupon / oncludes / commerce_coupon.checkout_pane.inc
global $user;
$uid = $user->uid;
$error = '';
// load the cart
$order = commerce_cart_order_load($uid);
// load the coupon from the coupon code
// see MySQL -> your-schema, table: commerce_coupon, column: code
$coupon = commerce_coupon_redeem_coupon_code($code, $order, $error);
// 302 to the cart
drupal_goto('checkout/' . $order->order_id);
