Magento 2 – How to Add Simple Product to Cart Instead of Configurable Product

addtocartconfigurable-productmagento2pluginsimple-product

I would like to add the simple product equivalent of the selected configurable product to the cart.
I would like to solve that with a plugin.
I would like to know where should I intercept the code, and how can I get the simple product if I have the configurable product with the selected attributes.

So what I did until now:

class Cart
{

protected $quote;
protected $request;
protected $configurableproduct;

public function __construct(
    \Magento\Checkout\Model\Session $checkoutSession,
    \Magento\Framework\App\Request\Http $request,
    \Magento\ConfigurableProduct\Model\Product\Type\Configurable $configurableproduct
){
    $this->quote = $checkoutSession->getQuote();
    $this->request = $request;
    $this->configurableproduct = $configurableproduct;
}

public function beforeAddProduct($subject, $productInfo, $requestInfo = null)
{

    $paramsData = $this->request->getParams();
    foreach($paramsData as $pId=>$param){ echo "booo";
            $params['product'] = $paramsData['product'][$pId];
            $params['super_attribute'] = $paramsData['super_attribute'][$pId];
        }
        var_dump($params);
    }
    $productId = (int)$this->request->getParam('product', 0);


    return array($productInfo, $requestInfo);
}
}

But it does not work…

It must be something with the foreach loop, because if I comment that out, the code runs.

So, this is my solution:

class Cart
{
protected $quote;
protected $request;
protected $configurableproduct;
protected $urlinterface;
protected $productrepository;

public function __construct(
    \Magento\Checkout\Model\Session $checkoutSession,
    \Magento\Framework\App\Request\Http $request,
    \Magento\ConfigurableProduct\Model\Product\Type\Configurable $configurableproduct,
    \Magento\Framework\UrlInterface $urlinterface,
    \Magento\Catalog\Model\ProductRepository $productrepository
){
    $this->quote = $checkoutSession->getQuote();
    $this->request = $request;
    $this->configurableproduct = $configurableproduct;
    $this->urlinterface = $urlinterface;
    $this->productrepository = $productrepository;
}

public function beforeAddProduct($subject, $productInfo, $requestInfo = null)
{

    $paramsData = $this->request->getParams();
    $productId = $paramsData['product'];
    $product = $this->productrepository->getById($productId);
    if ($product->getTypeId() == \Magento\ConfigurableProduct\Model\Product\Type\Configurable::TYPE_CODE) {
        $attributes = $paramsData['super_attribute'];

        $new_product = $this->configurableproduct->getProductByAttributes($attributes, $product);
        $new_productId = $new_product->getID();

        $productInfo = $new_productId;
    }

    return array($productInfo, $requestInfo);
}
}

Add to Cart via AJAX – Configurable Product with Options or Simple Product?

You can use either type, see Adding a product to the cart via querystring

To add a simple product with custom options simply add options[id]=[value] to the end. The basic structure is:

/path/to/magento/checkout/cart/add?product=$id&qty=$qty&options[$id]=$value

For adding a Configurable Product to the Cart via Querystring you need a url format like following

/checkout/cart/add?product=68&qty=1&super_attribute[528]=55&super_attribute[525]=56

Configurable Product – How to Redirect Simple Products

the code below should work only if the simple products are assigned to only one configurable product.
by default, magento allows you to add a simple product to as many configurable products you need.

Let's create a module and call it StackExchange_Redirect.
You will need the following files.

app/etc/modules/StackExchange_Redirect.xml - the declaration file

<?xml version="1.0"?>
<config>
    <modules>
        <StackExchange_Redirect>
            <codePool>local</codePool>
            <active>true</active>
            <depends>
                <Mage_Catalog />
            </depends>
        </StackExchange_Redirect>
    </modules>
</config>

app/code/local/StackExchange/Redirect/etc/config.xml - the module configuration file where you declare an observer for the product view page

<?xml version="1.0"?>
<config>
    <modules>
        <StackExchange_Redirect>
            <version>1.0.0</version>
        </StackExchange_Redirect>
    </modules>
    <global>
        <models>
            <stackexchange_redirect>
                <class>StackExchange_Redirect_Model</class>
            </stackexchange_redirect>
        </models>
    </global>
    <frontend>
        <events>
            <controller_action_predispatch_catalog_product_view>
                <observers>
                    <stackexchange_redirect>
                        <class>stackexchange_redirect/observer</class>
                        <method>redirectToConfigurable</method>
                    </stackexchange_redirect>
                </observers>
            </controller_action_predispatch_catalog_product_view>
        </events>
    </frontend>
</config>

app/code/local/StackExchange/Redirect/Model/Observer.php - the observer that should redirect to the configurable product page.

<?php 
class StackExchange_Redirect_Model_Observer
{
    public function redirectToConfigurable($observer)
    {
        $id = Mage::app()->getRequest()->getParam('id');
        $configurableParentIds = Mage::getResourceSingleton('catalog/product_type_configurable')
            ->getParentIdsByChild($id);
        if (isset($configurableParentIds[0])) {
            $mainProduct = Mage::getModel('catalog/product')
                ->setStoreId(Mage::app()->getStore()->getId())
                ->load($configurableParentIds[0]);
            Mage::app()->getResponse()->setRedirect($mainProduct->getProductUrl(), 301);
            Mage::app()->getResponse()->sendResponse();
            exit;
        }
        return $this;
    }
}

when you are done, clear the cache.
