Adding option to a product create error

Question

I'm extending the \Magento\Catalog\Block\Product\View file in AddToCart.php.

In my AddTocart, I've added this line :

$stock = $this->isInStockCustom($sku);

Now, I'm adding options to my products. It was working find until now.

But if I add an option to this product, in my log, I have this

Invalid method Magento\Catalog\Block\Product\View\Interceptor::isInStockCustom [] []

But if I remove the options, I don't have this error anymore.

Any help would be very appreciated.

Answer 1

Go it :

also need to change this in catalog_product_view.xml:

<block class="Vendor\Module\Block\AddToCart" 
name="product.info.addtocart.additional" as="product.info.addtocart" 
template="Magento_Catalog::product/view/addtocart.phtml"/>

Because additional option and simple product are not the same.
