如何在Magento中以编程方式将产品添加到购物车

Question

I am unable to add product to cart programmatically in Magento , I have tried every possible technique to add product with quantity to cart ( in Magento), following are the things I have tried and forums/sites taken help from. But none of them is working. I am using Magento Community edition 1.9.1.1. If anyone has any suggestion/answer, please share.

• Tried to do it via URL - eg [Magento_Store_URL]/checkout/cart/add?product=[id]&qty=[qty] or even like this - [Magento_Store_URL]/checkout/cart/add/product/[id]/qty/[qty] . I have also tried with form_key , generated via Mage::getSingleton('core/session')->getFormKey(); . All these stuff is not working at all. These things are mentioned here - Magento website
• Next, I have tried via programmatically, like this.

 <?php require_once 'app/Mage.php'; Mage::app(); $product=new Mage_Catalog_Model_Product(); $product->load(1); // 1 is product id, this is simple product ( type) $quote = Mage::getSingleton('checkout/session')->getQuote(); $quote->addProduct($product, 1 ); // quantity is 1 $cart = Mage::getSingleton('checkout/cart'); $cart->init(); // tried commenting this too! $cart->addProduct($product, 1 ); // quantity is 1 $cart->save(); Mage::getSingleton('checkout/session')->setCartWasUpdated(true); $quote->collectTotals()->save(); header('Location: '. 'http://localhost/magento/index.php/checkout/cart'); 

• Also tried following.

 <?php require_once 'app/Mage.php'; Mage::app(); $params=array( 'product'=>1, 'qty' => 3 ); $cart = Mage::getSingleton('checkout/cart'); $product = new Mage_Catalog_Model_Product(); $product->load($params["product"]); $cart->addProduct($product, $params); $cart->save(); Mage::getSingleton('checkout/session')->setCartWasUpdated(true); header('Location: '. 'http://localhost/magento/index.php/checkout/cart'); 

I have taken help from following websites.

• http://gzchauhan.blogspot.in/2012/03/programmatically-add-product-in-cart-in.html
• Magento - Add a product to the cart via query string without form_key parameter
• https://magento.stackexchange.com/questions/17997/product-not-adding-to-cart
• https://magento.stackexchange.com/questions/32967/programmatically-adding-product-to-cart-returns-empty-price
• http://subasd.com.np/magento-programmatically-add-product-to-cart-with-custom-options/

Is there any wrong in my code, whatever I have tried or is there any setting issue with my Magento Installation?

Update 1 I have tried below from the answer proposed to this question , still that is not working.

 $formKey = Mage::getSingleton('core/session')->getFormKey(); $params = array( 'product' => 3, 'qty' => 2, 'form_key' => $formKey ); $product = Mage::getModel('catalog/product')->setStoreId(Mage::app()->getStore()->getId())->load($params['product']); $cart = Mage::helper('checkout/cart')->getCart(); $cart->addProduct($product, $params); $cart->save(); 

Update 2

This is working, if I create a controller and place all code there, not working - in a standalone page that refers /app/Mage.php .

Since 1.8 you won't be able to add a product to the cart from a GET request alone, as you need to provide the form_key.

You should be able to add a product to the cart using the following:

form_key is the main thing to get right here.

$params //should include at least a valid form_key, qty

$product = Mage::getModel('catalog/product')
                    ->setStoreId(
                        Mage::app()
                        ->getStore()
                        ->getId()
                    )
                    ->load($product_id);

$cart = Mage::helper('checkout/cart')->getCart();
$cart->addProduct($product, $params);
$cart->save();

Take a look at the addProduct function in app\\code\\core\\Mage\\Checkout\\Model\\Cart.php if you need to debug (and then in the app\\code\\core\\Mage\\Sales\\Model\\Quote.php too)

Answer 2

Here is the easy way to add product to cart/quote:

$customer = Mage::getModel('customer/customer')->load($customerId);
$product = Mage::getModel('catalog/product')->load($productId);
// load quote by customer and store...
$quote = Mage::getModel('sales/quote')->setStore($storeId)->loadByCustomer($customerId);
$quote->addProduct($product, 1);
$quote->setIsActive(1);
$quote->collectTotals()->save();
