Why is it not cleared after paying for the goods and returning to the basket?

Question

PHP

There is a wordpress + woocommerce store. After paying with a card for the selected order using the return to cart button, it is not cleared. If you add a line of code:

<?php global $woocommerce; $woocommerce->cart->empty_cart(); ?>

then only the cart page is cleared, which is redirected to, but the product actually remains in the cart anyway. What can be done? Function to return to cart:

/**
     * Process the payment and return the result
    **/
    function process_payment( $order_id ) {

        $order  = wc_get_order( $order_id );

        return array(
            'result' => 'success',
            'redirect'  => $order->get_checkout_payment_url( true )
        );
    }

Answer 1
