我有以下问题： 我在前台通过jQuery进行计算，并希望将产品添加到与前端计算价格的车。

I have the following issue: I make calculations via jQuery in the frontend and want to add a product to the cart with the price calculated in the frontend.

我已经写了一个自定义模块与AjaxController实现增加车的一部分，但我知道有设置自定义价格的斗争。

I already wrote a custom module with an AjaxController to achieve the adding to cart part, but I know struggle with setting the custom price.

我的脚本是这样的：

$_prod = json_decode(Mage::app()->getRequest()->getPost('zapfsaeule_product'));

    $id = 347; // there is only this one bundle product added to the cart  viar this scipt, so a static id is enough.

    $params = array(
        'product' => $id,
        'related_product' => null,
        'bundle_option' => array(
            6 => 17, // static options for testing purpouses
            5 => 13), // 
        'qty' => 1 // static qty for testing as well
    );

    $cart = Mage::getSingleton('checkout/cart');

    $product = new Mage_Catalog_Model_Product();
    $product->load($id);

    $cart->addProduct($product, $params);
    $cart->save();

    Mage::getSingleton('checkout/session')->setCartWasUpdated(true);

    $this->getResponse()->setBody('true'); // setting response to true, because its an ajax request.
    $this->getResponse()->setHeader('Content-type', 'text/plain');

这就是code添加的产品。 对于设定价格，我想尽了办法中提到的关于stackexchange这个线程： http://magento.stackexchange.com/questions/4318/dynamically-calculated-prices-save-before-add-to-cart

That's the code for adding the product. For setting the price I tried the approach as mentioned in this thread on stackexchange: http://magento.stackexchange.com/questions/4318/dynamically-calculated-prices-save-before-add-to-cart

但没有奏效。我想在这里观察到的事件不发生在我的情况，因为我写了一个自定义脚本。

But it didn't work. I guess the event observed here doesn't occur in my case, because I wrote a custom script.

但后来还是会有问题，如果观察者方法是有效的，我将如何通过计算价格观察者？

But then there still would be the problem, IF the observer approach would work, how would I pass the calculated price to the observer?

我希望你明白的问题，可以帮助我解决这个问题。

I hope you understand the problem and can help me solve it.

在此先感谢！

最好的问候， 马丁

推荐答案

这涉及pretty的晚了，但我只是偶然发现了这一点。

This comes pretty late, but I just stumbled upon this.

我得到它的工作是这样的：

I got it to work like this:

$cart = Mage::getSingleton('checkout/cart');
$cart->addProduct($product, 1); // 1 = qty. Pass your qty and params.

$item = $cart->getQuote()->getItemByProduct($product);
$item->setCustomPrice(0); // or some other value
$item->setOriginalCustomPrice(0); // or some other value
$item->getProduct()->setIsSuperMode(true); // this is crucial 

$cart->save();
Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
