Limts and Messages

Hi,

Well, after the limits are checked, the system will trigger the event onAfterProductCheckQuantities(&$products, &$cart, $options)
and the error messages should be available in $cart->messages
So replacing the error messages should be possible with the development of a plugin implementing that event.
So in that event, you can get the user groups of the current user with Joomla's standard functions and then, overwrite the message with your own message based on that.
However, having different messages for different limits would be quite complex without any modifications to the core of HikaShop because in that trigger, there is no way to know which limit rule generated the error message. So it would require extra triggers inside the limit checking system, or at least add extra information attached to the error message in the $cart->messages arrya.
