Hide products that are out of stock OpenCart

If you need to hide products from the OpenCart catalog, the number of which is less than or equal to zero (out of stock), but there is an urgent need for these products to be opened via direct links, this solution is for you.

Out-of-stock items will automatically be hidden from both the catalog and all standard modules. At the same time, the index in search engines will not be changed, all pages of these products will still be available for indexing.

It also provides for disabling the Add to Cart button. Items with zero or negative stock balance cannot be added to the shopping cart!
