Unable to add same product more than once in CodeIgniter cart

Question

I am developing a shopping cart using codigniter 2.1.4. My issue is that I am unable to add same product more than one time in cart. But I can update the quantity in cart. So my requirement is that when cart the item for second time quantity should be increment to 2.

Answer 1

In your Cart.php replace the following code

unset($this->_cart_contents[$rowid]);

with this

if(isset($this->_cart_contents[$rowid]))
{
$this->_cart_contents[$rowid]['qty']++;
return $rowid;
 }

unset($this->_cart_contents[$rowid]);
