Magento 1.7 – How to Update Product Custom Options on Cart Page

cartcustom-optionsmagento-1.7

I have a simple product with custom options. When someone select any option and click on add to cart the product with the option goes to the cart where the product and selected option is shown.

Now here comes the situation where I need to alter the flow of Magento. I want to update that option value on cart page. Being more specific I want to make customer able to select or change option on cart page.

What i have done so far is that I have traced that items are shown from template/checkoput/cart/item/default.phtml.

I have placed my custom option dropdown there in a row of product and placed a save button near the dropdown. But again how do I get it updated?

Interesting question. I suggest doing it not by adding "Update" button to each items but using generic Magento "Update Cart" routine.

In this case we can assume that values of your drop-downs will be submitted with the form. Then you can observe checkout_cart_update_items_after event, get updated options with Mage::app()->getFrontController()->getRequest()->getParam(...) and change the selected option of each item.

This is just my theoretical assumptions but I'm sure you were not expecting complete code. Otherwise there's a commercial extension out there which is doing exactly what you need.

Magento – Product custom options are not displaying at cart page

It looks like your problem is on the product page, not in the cart. In order to add option data that page needs to submit a form, but the Add to Cart button is just doing a redirect on click

onclick="setLocation('http://paperhug.instantwebsitecloud.com/index.php/checkout/cart/add/uenc/aHR0cDovL3BhcGVyaHVnLmluc3RhbnR3ZWJzaXRlY2xvdWQuY29tL2luZGV4LnBocC9ncmVldGluZy1jYXJkcy9tb3RoZXJzLWRheS8xLWhvdXItZ3JlZXRpbmctY2FyZHMuaHRtbA,,/product/2/')"

should be:

onclick="productAddToCartForm.submit(this)"

It may have gotten changed when you were working on the add to cart buttons for the category pages.

Magento – How to add Simple product with custom options to cart

please check the Mage_Checkout_CartController and addAction() inside, you will find everything you need ;)

$cart   = $this->_getCart();
    $params = $this->getRequest()->getParams();
    try {
        if (isset($params['qty'])) {
            $filter = new Zend_Filter_LocalizedToNormalized(
                array('locale' => Mage::app()->getLocale()->getLocaleCode())
            );
            $params['qty'] = $filter->filter($params['qty']);
        }

        $product = $this->_initProduct();
        $related = $this->getRequest()->getParam('related_product');

        /**
         * Check product availability
         */
        if (!$product) {
            $this->_goBack();
            return;
        }

        $cart->addProduct($product, $params);
        if (!empty($related)) {
            $cart->addProductsByIds(explode(',', $related));
        }

        $cart->save();

        $this->_getSession()->setCartWasUpdated(true);
        /**
         * @todo remove wishlist observer processAddToCart
         */
        Mage::dispatchEvent('checkout_cart_add_product_complete',
            array('product' => $product, 'request' => $this->getRequest(), 'response' => $this->getResponse())
        );

        if (!$this->_getSession()->getNoCartRedirect(true)) {
            if (!$cart->getQuote()->getHasError()){
                $message = $this->__('%s was added to your shopping cart.', Mage::helper('core')->htmlEscape($product->getName()));
                $this->_getSession()->addSuccess($message);
            }
            $this->_goBack();
        }
