PHP / Wordpress / Woocommerce：防止读取url参数

Question

I was wondering if it would be possible to prevent url parameters from being read and used via PHP, specifically with Wordpress and Woocommerce.

The best example I can give is as follows, for a domain with wordpress and woocommerce installed, the following URL will add the appropriate product (with product id 999) to cart instantly:

www.example.com/?add-to-cart=999

I would like to prevent this parameter from being read if possible. All assistance is appreciated.

Answer 1

Alright, solved it, sort of. No GET Requests will go through on that particular parameter.

Edit class-wc-form-handler.php (found within the woocommerce/includes directory where your wordpress plugins are found) as follows:

find the function add_to_cart_action and add the following directly under the method declaration:

if ( $_SERVER['REQUEST_METHOD'] == 'GET'){
        return;
    }

All done, probably not the best answer, but it gets the job done.
