Magento – Magento 1.9 Not able to create quote item

magento-1.9PHPquotequoteitemsales-quote

I have the following function inside my model.This checks for the device id(custom column in sales quote) in database and if found and the qoute item has same product id then just updates the qty or else create a new quote.When I use this,It simply is not going to else part.Here is my code.

  public function _create(array $data)
{      
    $postParams = $this->getRequest()->getParams();
    $product_id=$postParams['product_id'];
    $qty=$postParams['qty'];
    $deviceId=$postParams['device_id'];
        $collection = Mage::getModel('sales/quote')->getCollection()->addFieldToFilter('device_id',  $deviceId);

foreach($collection as $item)
{

$quote = Mage::getModel('sales/quote')->load($item->getEntityId());
$cartItems = $quote->getAllItems();
foreach ($cartItems as $items) {
$productId = $items->getProductId();
 $qtys = $items->getQty();
if($productId==$product_id){
    $qtys+=$qty;
    $items->setQty($qtys);
    $ks=$items->getQty();
    $items->save();
    }
    else {

        $productModel = 'hello';

    }
}


}



     echo json_encode(array('success' => $productId,'quoteObj' => $productModel)); die;

}

Please help.Thanks

Updated : This code now updates the quantity as well as create a new quote if i pass same product id and device id .If same pid and device id is passed ith should only update not create another one.

public function _create(array $data)
{      
    $postParams = $this->getRequest()->getParams();
    $product_id=$postParams['product_id'];
    $qty=$postParams['qty'];
    $deviceId=$postParams['device_id'];
        $collection = Mage::getModel('sales/quote')->getCollection()->addFieldToFilter('device_id',  $deviceId);
        if ($collection->count()) {
            foreach($collection as $item)
{

$quote = Mage::getModel('sales/quote')->load($item->getEntityId());
$cartItems = $quote->getAllItems();
foreach ($cartItems as $items) {
$productId = $items->getProductId();
 $qtys = $items->getQty();
if (! $quote->hasProductId($product_id)) {

$productModel = Mage::getSingleton('catalog/product');
   $productObj = $productModel->load($product_id);
    if (!$quoteObj) {
       // echo 'if'; die;
        $quoteObj = new Mage_Sales_Model_Quote();
    }
    $store_id = Mage::app()->getStore()->getId();
    $storeObj = $quoteObj->getStore()->load($store_id);
    $quoteObj->setStore($storeObj);

    $quoteItem = Mage::getModel('sales/quote_item')->setProduct($productObj);
    $quoteItem->setQuote($quoteObj);
    $quoteItem->setQty($qty);
    $quoteItem->setStoreId($store_id);
    $quoteObj->addItem($quoteItem);
    $quoteObj->setStoreId($store_id);
    $quoteObj->collectTotals();
    $quoteObj->setCustomerId(null);
    $quoteObj->setDeviceId($deviceId); 
    $quoteObj->save();
    }
    else{
        $qtys+=$qty;
    $items->setQty($qtys);
    $ks=$items->getQty();
    $items->save();

    }

}

}
}
else{
$productModel = Mage::getSingleton('catalog/product');
   $productObj = $productModel->load($product_id);
    if (!$quoteObj) {
       // echo 'if'; die;
        $quoteObj = new Mage_Sales_Model_Quote();
    }
    $store_id = Mage::app()->getStore()->getId();
    $storeObj = $quoteObj->getStore()->load($store_id);
    $quoteObj->setStore($storeObj);

    $quoteItem = Mage::getModel('sales/quote_item')->setProduct($productObj);
    $quoteItem->setQuote($quoteObj);
    $quoteItem->setQty($qty);
    $quoteItem->setStoreId($store_id);
    $quoteObj->addItem($quoteItem);
    $quoteObj->setStoreId($store_id);
    $quoteObj->collectTotals();
    $quoteObj->setCustomerId(null);
    $quoteObj->setDeviceId($deviceId); 
    $quoteObj->save();
}



     echo json_encode(array('success' => $ds,'quoteObj' => $ks,'quoteObj' => $dss)); die;

to find if particular product is in quote

if (! $quote->hasProductId($product_id)) {
    // Product is not in quote so add your logic
}
else
{
   $item = $quote->getItemByProduct($product_id);
   $qty = $item->getQty();
   $item->setQty($qty);
   $items->save();
}

find is collection empty

if ($collection->count()) {
// Collection is not empty
}
else
{
}

After Update your code

public function _create(array $data)
{      
    $postParams = $this->getRequest()->getParams();
    $product_id=$postParams['product_id'];
    $qty=$postParams['qty'];
    $deviceId=$postParams['device_id'];
        $collection = Mage::getModel('sales/quote')->getCollection()->addFieldToFilter('device_id',  $deviceId);
        if ($collection->count()) {
            foreach($collection as $item)
            {
                $quote = Mage::getModel('sales/quote')->load($item->getEntityId());
                $cartItems = $quote->getAllItems();
                if (! $quote->hasProductId($product_id)) {

                    $productModel = Mage::getSingleton('catalog/product');
                    $productObj = $productModel->load($product_id);
                    if (!$quoteObj) {
                       // echo 'if'; die;
                        $quoteObj = new Mage_Sales_Model_Quote();
                    }
                    $store_id = Mage::app()->getStore()->getId();
                    $storeObj = $quoteObj->getStore()->load($store_id);
                    $quoteObj->setStore($storeObj);

                    $quoteItem = Mage::getModel('sales/quote_item')->setProduct($productObj);
                    $quoteItem->setQuote($quoteObj);
                    $quoteItem->setQty($qty);

                    break;
                }
                else{

                   $qty = $item->getQty();

                   $items->save();

Magento – Create Duplicate quote item instead of updating existing quote item for same product

To change what's getting added to the cart you need to observe an event before the quote item is created. This way you can choose to update the qty of an existing item, add one or more new items, or both. Unfortunateley there is no event between Mage_Checkout_CartController::addAction() and Mage_Sales_Model_Quote::addProduct(), so if you don't find a crazy workaround, you'll have to rewrite one of the methods in this control flow:

I'd suggest Mage_Sales_Model_Quote::addProductAdvanced() because this is where addItem() is called. Also, manipulating the product options and merging alone will not work because of the case where you want to add several new items (7 => 5 + 2)

To create separate items for the same product, i.e. prevent that they get merged again, it's enough to add an invisible custom option to each item with a unique value.

Another possible approach would be to observe sales_quote_collect_totals_before which is called every time you visit the cart, and then rearrange the quote.

For each product that should be treated like this: - check for items with qty > 5 - reduce the qty of those items to 5 - if there are items with qty < 5, add remaining qty up to 5 - add new items for the remaining qty (again, with a unique custom option)

Magento – How to change product name in quote item dynamically

Take a look at Magento change product name adding to cart

Use event sales_quote_item_set_product

class Mynamespace_Samples_Model_Observer
{
    public function salesQuoteItemSetProduct(Varien_Event_Observer $observer)
    {
        /* @var $item Mage_Sales_Model_Quote_Item */
        $item = $observer->getQuoteItem();

        //only change the item you want by product id
        if($item->getProductId() == xyz){
            $item->setName('Ians custom product name');
        }

        return $this;
    }
}
