Add to cart item Out Of Stock - ignore quantity check

[connor_ferry]

Hi folks,

I'm doing my own preorder plugin and I want to keep product Out Of Stock but make it available to add to cart.

I know there is option for backorders with product In Stock with quantity 0 - but it's not the case. I want to keep status Out Of Stock and quantity 0.

I want to ignore quantity check when product is added to cart for Out Of Stock items.

Basically when $_product->isSaleable() return false or 0 it shows Place Preorder but it's trigger normal Add to cart quantity check.

I will appreciate any help in this matter!

Hello @connor_ferry 

One more thing i know if you set 

  $productInfo->setIsSuperMode(true) ; 

then it will skip qty check

Before I've add 

  $productInfo->setIsSuperMode(true) ;

I'm receiving message:

We can't add this item to your shopping cart right now.

Where exactly to put this  $productInfo->setIsSuperMode(true) ;

In my files?

Hello @connor_ferry 

Magento\Checkout\Controller\Cart\Add.php

before this add line add 

 $product->setIsSuperMode(true) ;

$this->cart->addProduct($product, $params);

Hope it will help you.

Hi,

Thanks for quick reply.

So in file /vendor/magento/module-checkout/Controller/Cart/Add.php

I've add to line 111

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

$this->cart->save();

and now I'm receiving message:

Product that you are trying to add is not available.

What I'm missing?

Maybe another approach - how to disable changing status to Out Of Stock if quantity reach 0 and below?

I think it would be easier ro do
