WooCommerce Always redirect to checkout even if product already exists in cart

Question

How can I always redirect to WooCommerce checkout even if the product sold individually is already in cart?

I have my cart integrated in the checkout and WooCommerce will stay on the same page without going to checkout if that product is already in the cart.

P.S.

• I followed this to redirect to checkout when adding to cart (no need for cart page cause I have only one product)
• And this to show the cart on checkout

Answer 1

My fix was to hijack the add to cart flow of WooCommerce and redirect to checkout if the product already exists:

add_filter( 'woocommerce_add_to_cart_sold_individually_found_in_cart', 'bypass_add_to_cart_sold_individually_found_in_cart', 10, 2 );

function bypass_add_to_cart_sold_individually_found_in_cart( $found_in_cart, $product_id ) {
    if ( $found_in_cart ) {
        wp_redirect(wc_get_checkout_url());
        
        exit;
    }
    
    return $found_in_cart;
}
