Mini-minimal setup

[joe_g]

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';
}

After testing I can say that

 echo $padloper->cart->addProduct(1043);

works fine, but however

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

does not work

Why would that be?J

Yes, that link is only about adding.

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);
}
