How do I make a "Clear Cart" button in the shopping card section?
Not: Version 4.20

You need to add a button on the cart page and make a request when clicked to a method that deletes all the items of the cart for the current user. You can do so by

foreach (var item in _workContext.CurrentCustomer.ShoppingCartItems)
                _shoppingCartService.DeleteShoppingCartItem(item.Id);

and reload the page or you can make use of ajax

I'm a rookie. The questions may sound stupid. Sorry. Where do I add this code?

Well, you need to create an action method in a new controller or any existing controller may be in the ShoppingCartController(I am assuming you are modifying the source code rather than using a plugin for this).

 public virtual IActionResult ClearShoppingCart()
        {
         if(!_permissionService.Authorize(StandardPermissionProvider.ManageCurrentCarts))
                return AccessDeniedDataTablesJson();

            foreach (var item in _workContext.CurrentCustomer.ShoppingCartItems)
                _shoppingCartService.DeleteShoppingCartItem(item.Id);

            return RedirectToRoute("ShoppingCart");
        }

and invoke this method when the clear shopping cart button is clicked

I did as you said. But it didn't work. What did I do wrong?

I assume that the ActionMethod does not hit.  Because you do not add

        [HttpPost, ActionName("Cart")]
        [FormValueRequired("ClearShoppingCart")]

annotation/attributes on top of the IActionMethod. Change code is

  

[HttpPost, ActionName("Cart")]
        [FormValueRequired("ClearShoppingCart")]
        public virtual IActionResult ClearShoppingCart()
        {
           if (!_permissionService.Authorize(StandardPermissionProvider.ManageCurrentCarts))
                return AccessDeniedDataTablesJson();

            var shoppingCartItem = _workContext.CurrentCustomer.ShoppingCartItems.ToList();
            foreach (var item in shoppingCartItem)
                _shoppingCartService.DeleteShoppingCartItem(item.Id);

  
            return RedirectToRoute("ShoppingCart");
        }

Keep the cshtml as same. Because the button name is important. If you change the button name you also need to change the annotation.
