How to remove all cart items on button click?

Question

PHP

There is a component sale.basket.basket. Add a Delete Entire Cart button. I searched on the Internet and found this way:
in init.php add
if ($_POST["BasketDelete"] and CModule::IncludeModule("sale"))
{
CSaleBasket::DeleteAll(CSaleBasket::GetBasketUserID());
}
and add a button in the template

<input type="submit" value="Очистить корзину" name="BasketDelete">

Clicking on it will take you to the checkout page. And if you then return to the basket, then it is empty. Is there a way to do this without going to the checkout page?

Answer 1

after the basket form, I created another form with the post method, pushed the button there. Everything works as it should

Answer 2

Add after CSaleBasket::DeleteAll() the line LocalRedirect('reference to the basket');
