WooCommerce: Remove “add-to-cart=123” URL Parameter After Add to Cart

The “add-to-cart” parameter in WooCommerce is used to create a custom URL that adds a specific product to the shopping cart. The “123” value is the product ID, and you can even specify a custom quantity. By clicking a link with this parameter in the URL, the user can add the specified product (ID# 123 in this example) to their cart without having to navigate to the product page itself.

The problem is that WooCommerce itself doesn’t automatically remove the “add-to-cart” parameter after a successful add to cart, and if you reload the page you will add to cart again! So, let’s see how we can remove this parameter in case you disabled the “redirect to cart” option.

PHP Snippet: Remove “add-to-cart=123” From URL Upon WooCommerce Add to Cart

add_filter( 'woocommerce_add_to_cart_redirect', 'wp_get_referer' );

wp_get_referer is a function in WordPress used to retrieve the URL of the webpage that linked to the current one. It essentially tells you where the user came from before landing on the current page. Which means, this will take the user back to the original URL before they added to cart, hence removing the “add-to-cart” URL parameter!

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
