Question

Using a CartController.php override for the addAction function.

Basically I’m trying to take the custom options entered by a user, then generate a new product based off those options and add that to the cart instead. I have the first parts down, if a product doesn’t have a custom attribute flagged, it gets added like normal… but if it is flagged, it creates a new product and adds THAT to the cart instead.

I am successfully generating the new product and adding it to the cart, but I’m unable to get the custom options that the customer entered.

$defaultprod = $product->getDefaultprod();
$prodID = $product->getId();
$prodOpt = Mage::getModel("catalog/product")->load($prodID);

if (!$defaultprod == 1) {
$cart->addProduct($product, $params);
if (!empty($related)) {
    $cart->addProductsByIds(explode(',', $related));
}
$cart->save();
}
else
{
          // code to create/add new product here, adding new product + adding to cart functioning, but CANNOT retrieve customer's custom attribute input
}

Any advice?

Answer 1

This is what I just tried successfully to:

• avoid adding the original product to the cart
• retrieve custom options that were originally posted on add to cart

1) Create an observer

This observes the event controller_action_predispatch_checkout_cart_add

<controller_action_predispatch_checkout_cart_add>
    <observers>
        <myobserver_identification>
            <class>module/observer</class>
            <method>myCustomMethod</method>
        </myobserver_identification>
    </observers>
</controller_action_predispatch_checkout_cart_add>

2) Add this in MyNamespace_Module_Model_Observer

public function myCustomMethod() {
    $request = Mage::app()->getFrontController()->getRequest();

    /**
     * Avoid adding original product
     */
    $request->setParam('product', (bool) false);

    /**
     * Retrieve custom options posted on add to cart
     */
    $customOptions = $request->getParam('options');
}
