Magento 2 remove add to cart button for specific products?

Question

I have tried to remove the Add to cart button with many solutions out there, but none has worked. I'm using this solution: How to remove the Add to Cart button from Catalog pages in Magento 2?.

Also tried this one but the products were disabled, not the add to cart button: How to disable add to cart in magento 2

What I need to do, is something very simple, I just need to check in an if() condition if the ProductID of the product is different than 2 ids, so customer won't be able to add to cart products that are not the ones that can be bought.

Something like this is what I need to accomplish.

$productId = $product->getId();

if($productId != "2078" || $productId != "2079"){
    //disable the add to cart button of the rest of products
}
else{
//products ID are 2078 or 2079
return true;
}

Greetings!

Answer 1

You can also do by creating product attribute named "show add to cart" with yes/no option. You can set yes option by default and set no to those products that won't be able to show add to cart button and instead of that Id condition check with attribute value. It's good to keep product attribute when doing this kind of development rather to use product Id.
