checkout results displayed on the home menu

Hi,

That's because the Itemid parameter is missing for that after_end URL.
Normally, this parameter is added to the URL by the payment plugin.
For example, in the file plugins/hikashoppayment/paypal/paypal.php in the function onAfterOrderConfirm, you have this line of code to generate the after_end URL:

$return_url = HIKASHOP_LIVE.'index.php?option=com_hikashop&ctrl=checkout&task=after_end&order_id='.$order->order_id . $this->url_itemid;

Hi,

The checkout legacy setting has been removed from HikaShop since the support of Joomla 4 was added as the legacy checkout cannot work with Joomla 4.
The problem is not there.
As I said, it's the payment plugin which generates the URL /index.php?option=com_hikashop&ctrl=checkout&task=after_end&order_id=37&order_token=iPjxtJBx
If the Itemid parameter is missing from there, and if the code I talked about is in the payment plugin you're using, then the problem is that the Itemid information is missing when the payment plugin is generating the URL.
Which payment plugin are you using ? How is it configured ?
What did you configure in the "force a menu on checkout" setting of the HikaShop configuration ? (I would recommend to select a menu item of the type "hikashop checkout" in there, that might even help your situation to do that if it's not already the case)
Could you provide a link to the shop so that we could check your checkout ?

Hi,

The problem is in the code of the plugin.
It is generating the URL in onPaymentNotification. There $this->url_itemid is not available.
It's only available in onAfterOrderConfirm.
Replacing the line:

$returnUrl = HIKASHOP_LIVE.'index.php?option=com_hikashop&ctrl=checkout&task=after_end&order_id='.$order->order_id . $this->url_itemid;

$returnUrl = HIKASHOP_LIVE.'index.php?option=com_hikashop&ctrl=checkout&task=after_end&order_id='.$order->order_id . '&Itemid='.@$_REQUEST['Itemid'];
