我需要製作一個模塊,允許用戶輸入寬度和高度,然後它應該根據高度和寬度計算價格。 由於事先根據高度和寬度計算價格
我需要製作一個模塊,允許用戶輸入寬度和高度,然後它應該根據高度和寬度計算價格。 由於事先根據高度和寬度計算價格
讓我們說,你想這樣做的ID N°1從產品頁面的產品: 先在你product.tpl添加兩個輸入字段(或在您的module.tpl叫產品。 TPL)
<input name="height"><br>
<input name="width">
現在你需要得到它在你的module.php改價格動態地:
$id_product = 1;
$newPrice = 0;
$height = Tools::getValue('height');
$width = Tools::getValue('width');
//Price rules (change with your rules)
if($height > 10 && $width > 10) $newPrice = 10;
$specific_price = new SpecificPrice();
$specific_price->price = $newPrice;
$specific_price->id_cart = (int) $this->context->cart->id;
$specific_price->id_shop = 0;
$specific_price->id_shop_group = 0;
$specific_price->id_currency = 0;
$specific_price->id_country = 0;
$specific_price->id_group = 0;
$specific_price->id_customer = (int) $this->context->customer->id;
$specific_price->id_product = (int)$id_product;
$specific_price->id_product_attribute = 0;
$specific_price->from_quantity = 1;
$specific_price->reduction = 0;
$specific_price->reduction_type = 'amount';
$specific_price->from = '0000-00-00 00:00:00';
$specific_price->to = '0000-00-00 00:00:00';
$specific_price->add();
,如果你想將其添加到購物車
$cart->id_lang = (int)($this->context->cookie->id_lang);
$cart->id_currency = (int)($this->context->cookie->id_currency);
$cart->updateQty($qte, $id_product);
和訂單後完成你把正常價格,所以覆蓋重寫/控制器/前面的orderConfirmation控制器/ OrderConfirmationController.php:訂單完成
class OrderConfirmationController extends OrderConfirmationControllerCore
{
public $ssl = true;
public $php_self = 'order-confirmation';
public $id_cart;
public $id_module;
public $id_order;
public $reference;
public $secure_key;
public function getPriceBack($id_product){
$normalPrice = Product::getPriceStatic($id_product);
$specific_price = new SpecificPrice();
$specific_price->price = $normalPrice;
$specific_price->id_cart = (int) $this->context->cart->id;
$specific_price->id_shop = 0;
$specific_price->id_shop_group = 0;
$specific_price->id_currency = 0;
$specific_price->id_country = 0;
$specific_price->id_group = 0;
$specific_price->id_customer = (int) $this->context->customer->id;
$specific_price->id_product = (int)$id_product;
$specific_price->id_product_attribute = 0;
$specific_price->from_quantity = 1;
$specific_price->reduction = 0;
$specific_price->reduction_type = 'amount';
$specific_price->from = '0000-00-00 00:00:00';
$specific_price->to = '0000-00-00 00:00:00';
$specific_price->add();
}
public function init()
{
parent::init();
$this->id_cart = (int)(Tools::getValue('id_cart', 0));
$is_guest = false;
/* get normal price back */
$id_product = 1;
self::getPriceBack($id_product);
/* check if the cart has been made by a Guest customer, for redirect link */
if (Cart::isGuestCartByCartId($this->id_cart)) {
$is_guest = true;
$redirectLink = 'index.php?controller=guest-tracking';
} else {
$redirectLink = 'index.php?controller=history';
}
$this->id_module = (int)(Tools::getValue('id_module', 0));
$this->id_order = Order::getOrderByCartId((int)($this->id_cart));
$this->secure_key = Tools::getValue('key', false);
$order = new Order((int)($this->id_order));
if ($is_guest) {
$customer = new Customer((int)$order->id_customer);
$redirectLink .= '&id_order='.$order->reference.'&email='.urlencode($customer->email);
}
if (!$this->id_order || !$this->id_module || !$this->secure_key || empty($this->secure_key)) {
Tools::redirect($redirectLink.(Tools::isSubmit('slowvalidation') ? '&slowvalidation' : ''));
}
$this->reference = $order->reference;
if (!Validate::isLoadedObject($order) || $order->id_customer != $this->context->customer->id || $this->secure_key != $order->secure_key) {
Tools::redirect($redirectLink);
}
$module = Module::getInstanceById((int)($this->id_module));
if ($order->module != $module->name) {
Tools::redirect($redirectLink);
}
}
}
後必須清空購物車與id_product和DBB刪除規則:
$this->context->cart->deleteProduct(1);
Db::getInstance()->execute('DELETE FROM '._DB_PREFIX_.'specific_price WHERE id_customer='.(int)$this->context->customer->id);
這只是一個例子,不變量的測試不能使用,也許把對康斯坦特您的產品ID而言,希望它有助於
爲了改變價格動態,我應該更新cart.php updateQty函數嗎? –
是的,這是一個簡單的方法來做到這一點 – Melvita
這就是我面臨的問題: 比方說,我們有一個基準價格的產品:100 $ 用戶訂購具有自定義高度和寬度的產品,並且讓我們說價格成爲100 $ + 20 $ = 120 $ ,並且由於新價格是按照特定價格進行計算和添加的,所以在下一個訂單中基準價格將變爲120 $,並且我無法找到使價格返回到原始金額 –
