Remove "?add-to-cart=product-id" from Add to Cart URL when on the Cart page

Question

We use this type of Add to Cart URL on our site a lot of times: http://yourdomain.com/cart/?add-to-cart=25. The problem is after it redirects to the Cart page, if the client changes his/her mind and removes the recently added product, the Cart page loads and adds it again since "?add-to-cart=25" is on the URL.

My question is is it possible to remove the "?add-to-cart=product-id" part after the redirection to Cart?

Answer 1

The solution would be to lose the ?add-to-cart=25part of the URL. The simplest way to do that is with javascript History API:

history.pushState(null, "", location.href.split("?")[0]);

Docs: https://developer.mozilla.org/en-US/docs/Web/API/History_API

The DOM window object provides access to the browser's history through the history object. It exposes useful methods and properties that let you move back and forth through the user's history, as well as -- starting with HTML5 -- manipulate the contents of the history stack.

It was introduced in HTML5 so older browsers might not support it.

Answer 2

Combining @xnagyg's hook and @dev_masta's JS, this gets rid of ?add-to-cart in the cart page so you can freely use refresh and back button. Also doesn't affect AJAX functionality

add_action('woocommerce_add_to_cart_redirect', 'refresh_function');

function refresh_function(){
 if ( is_page( 'cart' ) || is_cart() ) {
 ?>
  <script>
    history.pushState(null, "", location.href.split("?")[0]);    
  </script>
 <?php
 }
}

Answer 3

This is my solution (redirect to the checkout page if the user clicked on a custom add-to-cart button):

function xnagyg_redirect_checkout_add_cart( $url ) {
  //continue only if we found add-to-cart in the URL!!!
  if ( empty( $_GET['add-to-cart'] ) || ! is_numeric( $_GET['add-to-cart'] ) ) {
    return false; //do not redirect
  }
  $url = get_permalink( get_option( 'woocommerce_checkout_page_id' ) ); //Redirect to Checkout page
  return $url;
}

add_filter( 'woocommerce_add_to_cart_redirect', 'xnagyg_redirect_checkout_add_cart' );
