Mini-minimal setup

Hi there,

I think what would help is a very minimal setup, a demo without ajax/htmx, templating etc. In the absence of that, here is a super basic question:

1. How do I add and remove a product to the cart purely via the API? This is for me to understand the basics. I'm imagining it would be something like

$cart = $padloper->getCart();

if(!$cart->addProduct(product_id)) {
  echo 'problems adding';
}

if(!$cart->removeProduct(product_id)) {
  echo 'problems removing';
}

Yes, that link is only about adding.

$padloper->cart->removeProduct(1043);

The argument you pass here should be the ID of the cart item, not the product ID, i.e.,

<?php

namespace ProcessWire;
// ==================
/** @var array $cartItems */
$cartItems = $padloper->getCart();
bd($cartItems, __METHOD__ . ': $cartItems at line #' . __LINE__);
foreach ($cartItems as $cartID => $cartItem) {
  /** @var stdClass $cartItem */
  echo "The ID of the cart item is: {$cartID}<br>";
  // OR
  // echo "The ID of the cart item is: {$cart->id}<br>";
  // REMOVE CART ITEM
  $padloper->cart->removeProduct($cart->id);
  // OR
  // $padloper->cart->removeProduct($cartID);
}
