Prestashop - create a cart by extarnal script

Question

I have a script (working) for a prestashop 1.7 to add product in my db

require_once('config/config.inc.php');
require_once('init.php');

$default_lang = Configuration::get("PS_LANG_DEFAULT");
$product = new Product();
$product->name = [$default_lang => "Acquisto cumulativo diretta online"];
$product->link_rewrite = "acquisto_online";
$product->price = 95.90;
$product->quantity = 10;
$product->id_category = [10];
$product->id_category_default = 10;
$bool = $product->add();
if ($bool)
{
    $product->updateCategories($product->id_category);
    
    StockAvailable::setQuantity((int)$product->id, 0, $product->quantity, Context::getContext()->shop->id);
    }

It's working fine, I can add my product in a category I make as "not visible" and I can use that product just fine.

Then I need to create (without login) a cart for a specific user with this product (and maybe other product he already have in his cart)

so I write my check on database for id_customer, and create an instance of customer

$customer = new Customer(3); // where 3 in this example is the correct id of the customer.

then I check on db if a cart is already exist for this id_customer, if I find a regular cart I just use

$cart = new Cart(ID_CART_I_FIND_ON_DB);
$cart->updateQty(1, 122); // where 1 is the quantity, 122 the id of my product

and it work perfectly, the user refreshing is cart can see the new product.

Now the problem:

if I don't find a regular cart, I need to create a new one first

$cart = new Cart();
$cart->id_customer = (int)($customer->id);
$cart->id_address_delivery = (int)  (0);
$cart->id_address_invoice = $cart->id_address_delivery;
$cart->id_lang = (int)(2);
$cart->id_currency = (int)(2);
$cart->id_carrier = 1;
$cart->recyclable = 0;
$cart->gift = 0;
$cart->add();
$cart->update();
$cart->save();
$cart->updateQty(1, 122);

it kinda works, I can see on my db this cart of course, I can see it in my Back Office pannel, but the user can't see it because of "secure key" and because of guest_id. I try to manually insert in db the correct secury key but nothing. I try to add a guest_id manually and then force the login of this user and sometimes the cart appears.

I'm sure I missing something. could someone help me with this? :)

Maybe there is a better way to "create" a new cart (if not exists) for a specific user from an external script (so without his cookie)

thanks

I actually find a workaround, maybe too long or just not elegant but it works.

Reading how the real code works I understand I need a session (with login) before making an actual cart for an user so I write:

$customer = new Customer(ID_USER);


$context=Context::getContext(); //I set a context manually

$context->customer = $customer;
    //create a cookie
    $context->smarty->assign('confirmation', 1);
    $context->cookie->id_customer = (int)$customer->id;
    $context->cookie->customer_lastname = $customer->lastname;
    $context->cookie->customer_firstname = $customer->firstname;
    $context->cookie->passwd = $customer->passwd;
    $context->cookie->logged = 1;
    
    if (!Configuration::get('PS_REGISTRATION_PROCESS_TYPE'))
    $context->cookie->account_created = 1;
    $customer->logged = 1;
    $context->cookie->email = $customer->email;

    $context->cookie->is_guest = !Tools::getValue('is_new_customer', 1);
    // Update cart address
    $context->cart->secure_key = $customer->secure_key;

then if cart didn't already exist of course:

$cart = new Cart();
    $cart->id_customer = (int)($customer->id);
    $cart->id_address_delivery = (int)  (0);
    $cart->id_address_invoice = $cart->id_address_delivery;
    $cart->id_lang = (int)(2);
    $cart->id_currency = (int)(2);
    $cart->id_carrier = 1;
    $cart->recyclable = 0;
    $cart->secure_key = $customer->secure_key;
    $cart->gift = 0;
    $cart->add();
    $cart->id_guest = $context->cart->id_guest;  
    $cart->update();
  $cart->save();

of course user need to login again to see the cart, but prestashop seemes to "auto-create" a cart every time a user login (for x time) so this procedure is only when a user didn't login on website or not have a cart for some reason.
