I think on the minute 13:20, i've got an error so i just:

Changes $result->affected_rows to $conn->affected_rows since affected rows is a property of the connection object for INSERT queries

it will be:

function getCartId($user_id)
{
global $conn;
$cart_id = null;
$stmt = "SELECT id FROM cart WHERE user_id = $user_id;";
if ($result = $conn->query($stmt)) {
if ($result->num_rows) {
$cart_id =
} else {
$stmt = "INSERT INTO cart (user_id) VALUES ($user_id);";
if ($conn->query($stmt)) {
if ($conn->affected_rows) {
$cart_id = $conn->insert_id;
}
}
}
}
return $cart_id;
}

Una pregunta más de cultura que de chisme como decimos en Colombia.
¿Cómo es la vida rutinaria en tu país?
Leo que actualmente el desarrollo web lo comanda tu país e india mas que los estados unidos
¿eres profesional en el ramo o gusto no por el arte?
