Prestashop: add an individual product to the cart

Question

I am writing my own controller for Prestashop. This is done to accomplish a simple task: 1. Create a new cart if it has not been created (works fine) 2. Get the attribute identifier from the database (works fine) 3. Assign a setting (one text box) 4. Add this product to the cart .

My current code is:

$idProduct = 1; // for me it always one
$qty= 1; // always add one item
$text = (string)Tools::getValue('textField9'); // string of text customization
$attribute = (int)Tools::getValue('sel_combination'); // atribute combination ID

// get cart id if exists
if ($this->context->cookie->id_cart)
{
    $cart = new Cart($this->context->cookie->id_cart);
}

// create new cart if needed
if (!isset($cart) OR !$cart->id)
{
    $cart = new Cart();
    $cart->id_customer = (int)($this->context->cookie->id_customer);
    $cart->id_address_delivery = (int)  (Address::getFirstCustomerAddressId($cart->id_customer));
    $cart->id_address_invoice = $cart->id_address_delivery;
    $cart->id_lang = (int)($this->context->cookie->id_lang);
    $cart->id_currency = (int)($this->context->cookie->id_currency);
    $cart->id_carrier = 1;
    $cart->recyclable = 0;
    $cart->gift = 0;
    $cart->add();
    $this->context->cookie->id_cart = (int)($cart->id);    
    $cart->update();
}



// get product to add into cart
$productToAdd = new Product(1, true, (int)($this->context->cookie->id_lang));

// default attributes
// $default_id_product_attribute = Product::getDefaultAttribute($productToAdd->id, $minimumQuantity);

// assign real attributes
$attributes =  $attribute;
$cart->update();
// add customizatated text
$customization = $this->context->cart->addTextFieldToProduct((int)($idProduct), 9, Product::CUSTOMIZE_TEXTFIELD, $text );

$exising_customization = Db::getInstance()->executeS('SELECT id_customization FROM '._DB_PREFIX_.'customized_data ORDER BY id_customization DESC LIMIT 0,1');


$customization = $exising_customization[0]['id_customization'];



Db::getInstance()->execute('UPDATE ps_customization SET in_cart = 1, id_product_attribute = '.$attributes.' WHERE id_customization = ' .$customization);

// add product to cart
$cart->updateQty($qty, (int)($idProduct), (int)($attributes), (int)($customization), Tools::getValue('op', 'up'));
$prods = $cart->getProducts(true);
print_r ($prods[0]['id_customization']);
// update cart
$cart->update();

A cart has been created and a product has been added. The cart says that there is one product, but it is not displayed. After rebooting the above code, the basket shows 2 items with the corresponding settings.

, , . ($ cart- > getProducts (true), ['id_customization'] ), . .
