A Customer can buy only 1 quantity of a product, how to?

[Luca S.]

Hello,
i'm offering a FREE product (shipping excluded) in my store but i want disable the quantity purchasable from a singular client.
So how to set 1 as max quantity purchasable from a customer ONLY on a specific product?

Thanks

Hi,

This is my solution. You have to edit cart.php

//update the cart...
if ($add OR Tools::getIsset('update') OR $delete)
{
//get the values
$idProduct = intval(Tools::getValue('id_product', NULL));
$idProductAttribute = intval(Tools::getValue('id_product_attribute', Tools::getValue('ipa')));
$customizationId = intval(Tools::getValue('id_customization', 0));
$qty = intval(abs(Tools::getValue('qty', 1)));
..........
..........
}

Change it to:

//update the cart...
if ($add OR Tools::getIsset('update') OR $delete)
{
//get the values
$idProduct = intval(Tools::getValue('id_product', NULL));
$idProductAttribute = intval(Tools::getValue('id_product_attribute', Tools::getValue('ipa')));
$customizationId = intval(Tools::getValue('id_customization', 0));
$qty = intval(abs(Tools::getValue('qty', 1)));

if($idProduct == 1234567890) $qty = 1;
..........
..........
}
