WooCommerce: Add Product to Cart When Visiting a Specific Page

We’ve already seen how to add a product to cart automatically when a user enters your website. However, I needed a different functionality on this same website, and specifically I wanted a product added to cart only when a user like you visits a specific WordPress page ID.

If you wish to test, go to my free video tutorial page called “How to Customize the WooCommerce Single Product Page“. As soon as the page loads a product is magically added to cart, so that the WooCommerce Checkout on that same page is populated with the hidden item. If you go to my Cart page right after visiting that landing page, you can verify there is a product in there.

So, how did I do it?
