Magento Grouped Products – Simple Products with Custom Options

custom-optionsgrouped-productsmagento-1.8products-management

I hope someone can help or knows of an extension that adds the functionality I require.

I have multiple simple products that each have their own custom options.

I then need to add these simple products to a bundled product. Magento out of the box only allows simple products without custom options to be added.

I managed to allow custom options on bundle products by using the following code (it does edit some core files and there are a few paid extensions that achieve similar functionality):

Edit for file app/code/core/Mage/Bundle/Model/Observer.php, namely just comment some code out as follows:

/*
        if ($product->getPriceType() == '0' && !$product->getOptionsReadonly()) {
            $product->setCanSaveCustomOptions(true);
            if ($customOptions = $product->getProductOptions()) {
                foreach (array_keys($customOptions) as $key) {
                    $customOptions[$key]['is_delete'] = 1;
                }
                $product->setProductOptions($customOptions);
            }
        }
*/

To get rid of “Bundle with dynamic pricing cannot include custom defined options. Options will not be saved.” message you should hack app/design/adminhtml/default/default/template/catalog/product/edit/options.phtml template:

//show error message
/*
if ($('price_type')) {
    if ($('price_type').value == '0' && $('dynamic-price-warrning')) {
        $('dynamic-price-warrning').show();
    }
}
*/

I found this in the following thread on Magento's forums: http://www.magentocommerce.com/boards/viewthread/14910/P15/#t208213

I then required defaults to be set for the custom option on bundle products (and other products that used listed options) and used this extension to implement the functionality: https://github.com/magebuzz/Magebuzz_Customoption

Magento – Strange problem with custom options

You should be able to simply set the options against a product and then call save on a product as the options are created in the _afterSave. After creating your options array simply set that the product has options, attach the options and then continue with your normal save process.

$product->setProductOptions($options);
$product->setCanSaveCustomOptions(true);

Forget about creating the options as the product model should do this for you, so you no longer need the following code.

$opt = Mage::getModel('catalog/product_option');
$opt->setProduct($product);
$opt->addOption($options);
$opt->saveOptions();

Magento – Add custom options while adding grouped product to cart

I found a solution which does not need an observer.

I had to do a rewrite to Mage_Sales_Model_Quote. More specific the method addProductAdvanced()

Bad news: You can not simply use parent::addProductAdvanced() and then do your own stuff. You have to copy the original code and fill it up with your code.

Here is what I did (look out for the comment starting with /********):

public function addProductAdvanced(Mage_Catalog_Model_Product $product, $request = null, $processMode = null) {
    if ($request === null) {
        $request = 1;
    }
    if (is_numeric ( $request )) {
        $request = new Varien_Object ( array (
                'qty' => $request 
        ) );
    }
    if (! ($request instanceof Varien_Object)) {
        Mage::throwException ( Mage::helper ( 'sales' )->__ ( 'Invalid request for adding product to quote.' ) );
    }

    $cartCandidates = $product->getTypeInstance ( true )->prepareForCartAdvanced ( $request, $product, $processMode );

    /**
     * Error message
     */
    if (is_string ( $cartCandidates )) {
        return $cartCandidates;
    }

    /**
     * If prepare process return one object
     */
    if (! is_array ( $cartCandidates )) {
        $cartCandidates = array (
                $cartCandidates 
        );
    }

    $parentItem = null;
    $errors = array ();
    $items = array ();
    foreach ( $cartCandidates as $candidate ) {
        // Child items can be sticked together only within their parent
        $stickWithinParent = $candidate->getParentProductId () ? $parentItem : null;
        $candidate->setStickWithinParent ( $stickWithinParent );
        $item = $this->_addCatalogProduct ( $candidate, $candidate->getCartQty () );

        /******** own modification for custom option GROUPSKU*/
        if($product->isGrouped()){
            $additionalOptions = array (
                    'options' => array (
                            'label' => 'GROUPSKU',
                            'value' => $product->getSku ()
                    )
            );
            $item->addOption ( new Varien_Object ( array (
                    'product' => $item->getProduct (),
                    'code' => 'additional_options',
                    'value' => serialize ( $additionalOptions )
            ) ) );
        }
        /******** own modification end*/

        if ($request->getResetCount () && ! $stickWithinParent && $item->getId () === $request->getId ()) {
            $item->setData ( 'qty', 0 );
        }
        $items [] = $item;

        /**
         * As parent item we should always use the item of first added product
         */
        if (! $parentItem) {
            $parentItem = $item;
        }
        if ($parentItem && $candidate->getParentProductId ()) {
            $item->setParentItem ( $parentItem );
        }

        /**
         * We specify qty after we know about parent (for stock)
         */
        $item->addQty ( $candidate->getCartQty () );

        // collect errors instead of throwing first one
        if ($item->getHasError ()) {
            $message = $item->getMessage ();
            if (! in_array ( $message, $errors )) { // filter duplicate messages
                $errors [] = $message;
            }
        }
    }
    if (! empty ( $errors )) {
        Mage::throwException ( implode ( "\n", $errors ) );
    }

    Mage::dispatchEvent ( 'sales_quote_product_add_after', array (
            'items' => $items 
    ) );

    return $item;
}

This way all the products that are added to the cart using a grouped product now have the custom option.
