Simple way to to Increase the Number of Cross-sell Items in cart from 4 to 12?

Question

I can't believe that Magento just decides for everyone that they should ONLY have 4 cross-sell items and that's it! I have 12 and I want all 12 of them to appear hopefully without the need to re-write half of the Magento code!

I found this:

How to Increase the Number of Crosssell Items in Cart?

but the article seems to be written for an older version of Magento. I have Magento 1.9.1

Is there really no simple way to do this?

Answer 1

You have to copy this file in local folder with same directory structure:

app/code/core/Mage/Checkout/Block/Cart/Crosssell.php

To

app/code/local/Mage/Checkout/Block/Cart/Crosssell.php

And change the max limit $_maxItemCount of cross sell as you want

class Mage_Checkout_Block_Cart_Crosssell extends Mage_Catalog_Block_Product_Abstract
{
    /**
     * Items quantity will be capped to this value
     *
     * @var int
     */
    protected $_maxItemCount = 4;
