define maximum number of items in shopping cart

[bothygesen]

Hi,
I want to set the maximum number of items in the shopping cart to 1.

I searched online and found the following code. But it doesnt seem to work and i can not reach the who provided the code.

This is the code:

 

Edit file located at controllers/OrderController.php

Go to line 45 and replace

global $isVirtualCart, $orderTotal;

with

global $isVirtualCart, $orderTotal, $cart, $cookie;

Now go to line 67 and paste below code on or after line 67

$max_items = 2;

$cart_rs = mysql_query("select sum(quantity) as item_count from "._DB_PREFIX_."cart_product where id_cart='".$cart->id."'");

$row

= mysql_fetch_assoc($cart_rs);

$cart_count = $row["item_count"];

if ($cart_count > $max_items)

{

$this->step = 0;

$this->errors[] = Tools::displayError('Maximum '.$max_items.' items allowed per order');

}

You can change the value of variable $max_items to set your desired maximum number of items allowed in shopping cart.

This code works fine with prestashop 1.4 or higher.

****

can anyone give me an idea what the problem is. we are using version 1.4.6.2

all hel appreciated...

SOLVED!

i decided to use quantity limits module for prestashop

after you installed the code did you set force compile to 'yes'? i.e. prefernces-->performance.

Is there any code like this for prestashop 1.6?
