Hi,

I have recently taken over two sites, and subsequently updated to the latest versions of Joomla and Hikashop Business.

Both sites are using a Gantry template.

Both sites appear to have a custom solution to displaying the number of items added to the cart.

I did the Joomla update two days ago and the cart items update were still working, however following the update of Hikashop the cart items are no longer updating.

The error I have posted in this post is the same on both sites. (I have now switched error reporting off)

I have followed the error and there is a file called "cart_items.php" in a "tests" folder within the root folder.

Here is the code in the cart_items.php file:

<span style="font-family: courier new, courier, monospace;">
<?php
require_once('/home/wetroomi/public_html/diywetroom.com/administrator/components/com_hikashop/helpers/helper.php'); 
$class = hikashop_get('class.cart');
$rows = $class->get();
$qty = 0;
if(!empty($rows)){
foreach($rows as $k =>$row){
if($row->cart_product_option_parent_id) continue;
$qty += $row->cart_product_quantity;
}
} 
echo $qty; 
?>
</span>

<div id="mobile-logo">
<div class="mobile-logo-content">
<a href="/index.php"><img src="images/logo.png"></a>
</div>
</div>
<div id="cart">
<div class="items">
{source file=tests/cart_items.php}{/source}
<!--Shopping CART link -->
</div>
<div class="cart-content">
<a href="/checkout"><img src="images/icons/cart.png"></a>
</div>
</div>

Thankyou so much, Nicolas.

I'll give it a go and get back to you.

Hi Nicolas,

I tried adding the code but it just gave me a blank white screen when I refreshed the home page.

Any ideas as to what might cause that?

Hi,

As a further update to my message earlier - I realised Joomla error messages were turned off. So I switched it on and put the code back in.

This is the message it gives:

Fatal error: Cannot declare class hikashop, because the name is already in use in /home/wetroomi/public_html/diywetroom.com/administrator/components/com_hikashop/helpers/helper.php on line 29

I'm afraid I'm still not quite sure what that means exactly.

Line 29 code is this:

jimport('joomla.application.component.controller');
