Magento CE 1.9 Add Product to Cart

Question

I am making rest api's for add product to cart for that I wrote this code:

public function _create(array $data) {

        $id = $data['id'];
        $qty = $data['qty'];

       $product = Mage::getModel('catalog/product')                 
                         // load the product object
                         ->load($data['id']);

       $quote = Mage::getModel('sales/quote');
       $quote->addProduct($product, $qty);

       $quote->collectTotals()->save();

 return json_encode(array("customer", $quote->getId()));

}

from this the product successfully adding in shopping cart(sales_flat_quote table) and it returns quote ID but I want to add this product to particular(logged in) user's cart for that I load quote from customer like this:

$customer = Mage::getModel('customer/customer')->load(21);

// Load quote by Customer
$quote = Mage::getModel('sales/quote')
             ->loadByCustomer($customer);

But still it is not associating with customer(in table customer ID is 0). Please let me know where I am doing wrong or I have to do more for that.

If I understand correctly, your complete code is like this

public function _create(array $data) {

        $id = $data['id'];
        $qty = $data['qty'];

       $product = Mage::getModel('catalog/product')                 
                         // load the product object
                         ->load($data['id']);

       $customer = Mage::getModel('customer/customer')->load(21);

       // Load quote by Customer
       $quote = Mage::getModel('sales/quote')
              ->loadByCustomer($customer);

       $quote = Mage::getModel('sales/quote');
       $quote->addProduct($product, $qty);

       $quote->collectTotals()->save();

      return json_encode(array("customer", $quote->getId()));

}

Instead of, load quote by customer object try to load this quote by customerId like this

// Load quote by Customer
$quote = Mage::getModel('sales/quote')
         ->loadByCustomer($customer->getId());

I've tested this one on Magento 1.9.0.1 just right now and it works fine. Here my code

I can access the user because it is identified by my application via token ...

$customer = Mage::getModel('customer/customer')->load($this->getApiUser()->getUserId());
$customer_ID = $customer->getId();

$quote = Mage::getModel('sales/quote')->loadByCustomer($customer_ID);

Hope it's help you

The working code is:

$store = $this->_getStore();
    Mage::app()->setCurrentStore($store->getId());

    $customer_ID = 10;

    $customer = Mage::getModel('customer/customer')->load($customer_ID);

    // load quote by customer
    $quote = Mage::getModel('sales/quote')->loadByCustomer($customer_ID);

    $quote->assignCustomer($customer);

    $product = Mage::getModel('catalog/product')
                         // set the current store ID
                         ->setStoreId(Mage::app()->getStore()->getId())
                         // load the product object
                         ->load($data['id']);

    // Add Product to Quote
    $quote->addProduct($product,$data['qty']);

    // Calculate the new Cart total and Save Quote
    $quote->collectTotals()->save();

Here is the working code:

$customer = Mage::getModel('customer/customer')->load($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();

Here is the working code to logged in user's cart

require_once '../app/Mage.php';
Mage::app();
umask(0);

Mage::getSingleton('core/session', array('name' => 'frontend'));

$product_id = '98';
$qty = '1'; 
$product = Mage::getModel('catalog/product')->load($product_id);
$cart = Mage::getModel('checkout/cart');
$cart->init();
$cart->addProduct($product, array('qty' => $qty));
$cart->save();
Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
Mage::getSingleton('core/session')->addSuccess('Product added successfully');

$cart =array(
'status' => True,
'Message' => 'Product added to cart successfully.'
);
echo json_encode($cart);
