Multi Carts don't work from front-end

Experimenting with multi-carts, interesting concept, but creating a second cart from the front-end doesn't work. A message is displayed indicating the cart will be visible when products are added, but any newly added items go to the original cart.

The wishlists feature suffers from the same flaw. It works if you create new cart / wishlist from the back-end, but customers can't create more than one wishlist or cart.

Hi,

In the file: "yourSite\administrator\component\com_hikashop\classes\cart.php" in the function "loadCart()" is the code:

if($app->getUserState(HIKASHOP_COMPONENT.'.'.$this->cart_type.'_new', '0') == '0'){

It isn't commented.
The described functionality doesn't work on your demo site either.

Hi,

I tried on my end and this functionality is working fine, the correction will be in the next release which will arrive before the end of the month.

I'm having the exact same problem. I thought, I just didn't get how to use the MultiCart/Wishlist feature, but reading the preceding posts I think this is a bug.
I can confirm that this isn't working on your demo page, either. (at least for Google Chrome 22.0.1229.79 - Windows 7)

In addition, this if statement you referred to:

In that case, I misunderstood Xavier, sorry. I thought by "working on our end" he meant "should be working on yours, as well.

Thanks for your reply, I'm looking forward to Ver2!

Hi,

I needed this working by tomorrow as it was presented to my client in a previous version ( we upgraded last week )

After some hour of testing, I did the following:

1. Add the given code line to the loadCart() method of the cart class: (and the closing bracket)

if($app->getUserState(HIKASHOP_COMPONENT.'.'.$this->cart_type.'_new', '0') == '0'){ 

$app->setUserState(HIKASHOP_COMPONENT.'.'.$cart_type.'_new', '0');

$app->setUserState(HIKASHOP_COMPONENT.'.'.$cart_type.'_new', '1');

Now, after installing HikaShop 2.0, I still couldn't get MultiCarts working properly.

Firstly, I got an error when trying to access "Show the carts" from the customer account page:
Fatal error: Call to a member function get() on a non-object in /var/www/components/com_hikashop/views/cart/view.html.php on line 248 (and 49 respectively)
I resolved this by commenting out the according lines in the view, since I don't intend to use wishlists anyway. Otherwise, this would probably pose another problem.

Secondly, HikaShop doesn't seem to load the current cart after user login. This might actually be a feature rather than a bug - maybe you don't want this stuff back anyway. However, I need to rely on the loaded cart having the same contents as the cart marked current in the MySQL table to manipulate these contents with ajax requests. I managed to write a module, that does this loading on login for me, but I fear that this will run into other problems sooner or later...¹⁾
TL;DR: This script loads the last modified cart, makes it current and redirects to the index.php of your page

<?php
// This script loads sets the last modified cart as the current cart and redirects to /index.php
// I use this as a module, but it shouldn't matter how you execute this.
// You could even override a HikaShop View with it.
// You'll probably have to adjust a few things if you want to implement it (the ajax request URL, for example)

//don't allow other scripts to grab and execute our file
defined('_JEXEC') or die('Direct Access to this location is not allowed.');

if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php')){
	echo 'This module can not work without the Hikashop Component';
	return;
};

$myDatabase = JFactory::getDBO();

// get the id of the last modified cart for the current user
$query = "SELECT * FROM #__hikashop_cart WHERE `user_id`='".hikashop_loadUser(1)->id."' AND cart_modified=(SELECT MAX(cart_modified) FROM #__hikashop_cart)";
$myDatabase->setQuery($query);
$result = $myDatabase->query();
$cartId = $myDatabase->loadObject()->cart_id;
?>
<script type="text/javascript">
document.body.onload = function(){
	loadCart();
}

function loadCart(){
	<?php /* sends ajax request to load the right cart */ ?>
	document.getElementsByClassName('contentLayout')[0].innerHTML = '<h1 style="text-align:center !important;">Your login was successful. Please wait while you\'re being redirected.<h1>';
	var xmlHttp = null;
	try {
	    xmlHttp = new XMLHttpRequest();
	} catch(e) {
	    try {
	        xmlHttp  = new ActiveXObject("Microsoft.XMLHTTP");
	    } catch(e) {
	        try {
	            xmlHttp  = new ActiveXObject("Msxml2.XMLHTTP");
	        } catch(e) {
	            xmlHttp  = null;
	        }
	    }
	}
	if (xmlHttp) {
	    xmlHttp.open('GET', '<?php JURI::base() ?>/index.php?option=com_hikashop&ctrl=cart&task=setcurrent&cart_id=<?php echo $cartId; ?>&cart_type=cart&Itemid=25', true);
	    xmlHttp.onreadystatechange = function () {
	        if (xmlHttp.readyState == 4) { 
				window.location = '<?php 
					if($_GET['redirectto'])	echo base64_decode($_GET['redirectto']);
					else { 
						JURI::base();
						echo "/index.php";
					}
				?>';
			}
	    };
	    xmlHttp.send(null);
	}
}
</script>

I also noticed that carts are not marked as active in the showcarts view.

Phew! With the help of vast amounts of coffee, I finally got my stuff working.
For my product/listing_table view I used to look up the current cart in the MySQL database to display the respective quantities from the cart next to each product. Since the actually loaded carts on the front end sometimes don't (or better: hardly ever) correlate to the carts marked current in the MySQL table, this would not work anymore.

By digging around in the HikaShop source, I found out that I could use

$myApp = JFactory::getApplication();
$newCartId = $myApp->getUserState(HIKASHOP_COMPONENT.'.cart_id','0');

Carts are also associated to session IDs. Also, if you are logging in, and if Hikashop doesn't auto load the cart, you shouldn't expect to find the correct cart ID in the session var.

Why don't you just put a cookie with the user's last cart ID and get the ID from there after login?

By using the cart helper class they put as an example in the documentation?

Nik, add me to skype: chongkan
