Add a custom option to a quote item (product in the cart)?

Question

I\'m running Magento 1.7.

I\'m trying to add a quote item option, a custom one, in sales_flat_quote_item_option.

I have tried with addOption and addCustomOption

Answer 1

Yes this is possible, you need to use the observer

I have been adding Delivery date with each product in the orders

So you can change this to be the Option you want to add to each product or so.

         
            
                
                    YOUR_CLASS_NAME
                    setProductInfo

public function setProductInfo($observer)
{
    if ('checkout_cart_add' != $observer->getEvent()->getControllerAction()->getFullActionName()) {
        return;
    }
    $request = Mage::app()->getRequest();
    $prId = $request->getParams();
    $product = Mage::getModel('catalog/product')->load($prId['product']);
    // fixed spelling of cofigurable/configurable
    if ($product->getTypeId() == 'configurable') {
        return $this;
    }

    if (!$product->getHasOptions()) {
        $optionID = $this->saveProductOption($product);
    } else {
        $options = $product->getOptions();
        if ($options) {
            foreach ($options as $option) {
                if ($option->getTitle() == 'Delivery Date') {
                    $optionID = $option->getOptionId();
                }
            }
        }
        if (empty($optionID)) {
            $optionID = $this->saveProductOption($product);
        }
    }

    $deliveryDate = $prId['delivery_date'];
    if (!empty($deliveryDate)) {
        $opt['options'] = array($optionID => $deliveryDate);
        $request->setParams($opt);
    }

    return $this;
}

function saveProductOption($product)
{

    $store = Mage::app()->getStore()->getId();
    $opt = Mage::getModel('catalog/product_option');
    $opt->setProduct($product);
    $option = array(
        'is_delete' => 0,
        'is_require' => false,
        'previous_group' => 'text',
        'title' => 'Delivery Date',
        'type' => 'field',
        'price_type' => 'fixed',
        'price' => '0.0000'
    );
    $opt->addOption($option);
    $opt->saveOptions();
    Mage::app()->setCurrentStore(Mage::getModel('core/store')->load(Mage_Core_Model_App::ADMIN_STORE_ID));
    $product->setHasOptions(1);
    $product->save();

    $options = $product->getOptions();
    if ($options) {
        foreach ($options as $option) {
            if ($option->getTitle() == 'Delivery Date') {
                $optionID = $option->getOptionId();
            }
        }
    }
    Mage::app()->setCurrentStore(Mage::getModel('core/store')->load($store));
    return $optionID;
}
