Hi there,

I'm trying to make a hikashop plugin for 11the bottle for free in my shop.

I've succeeded in adapting the price with a plugin, but the subtotal and the total in the cart are not changing on 12th product.
I think i need function onBeforeCartSave(&$element,&$do) to do this. Do you have a documentation about the $element?
I don't know how to adress the product price in this element.

Or do i have to make a change in the subtotal/total calculation? I so, what file do i have to adapt?

Thx

My plugin for now:

<?php

defined('_JEXEC') or die;
?><?php

class plgHikashopTwelveforeleven extends JPlugin {
		
	function plgTwelveforeleven(&$subject, $config){
		parent::__construct($subject, $config);
	}
		
	//function onBeforeCartSave(&$element,&$do) {
		//$lst1 = $element->cart_products;
		//foreach ($lst1 as $item) {
			//if ($item->cart_product_total_quantity == 12) {
				//$element=null;
				//$item->prices[0]->price_value_with_tax = 1 * $item->prices[0]->price_product_id;
				//}
		//}
	//}
	
	function onAfterCartProductsLoad(&$cart) {
		$lst1 = $cart->products;
		//echo"<pre>";var_dump($lst1);
		foreach ($lst1 as $item) {
			if ($item->cart_product_total_quantity == 12) {
				$item->prices[0]->price_value_with_tax = 11 * $item->prices[0]->price_id;
				}
		}
	}
	
}

Krgds, Matthieu

Hi,

The total is calculated dynamically when the cart is loaded. So onBeforeCartSave won't help you.
In the function onAfterCartProductsLoad you are called after the total has been calculated in $cart so you would have to recalculate the total in $cart on top of updating the product price.
Alternatively, you could do similarily to what we do in the plugins which dynamically change the price of the products:
www.hikashop.com/marketplace/category/39-products.html
They implement the hikashop_product_price_for_quantity_in_cart function to change the price of the product before the total is calculated by the cart loading system.

I just added this code to the plugin. Works great. Thanks!

$tot = 0;
foreach ($lst as $item) {
$tot += $item->prices[0]->price_value_with_tax;
}
$cart->full_total->prices[0]->price_value_with_tax = $tot;
