Currently, if you have the 'customer redemption' set to a number other than 0 (unlimited) it will not consider guest orders in the count meaning a customer using guest order can use the coupon more than the customer redemption set amount. Coupon redemption will work as intended if the customer is logged in (is set to 1 the customer can use it once and will not work a second time). This edit ill require the customer to login before using any coupon.
extensions/cart_module/language/english/cart_module_lang.php
Add anywhere (suggest last line)
$lang['coupon_register'] = '<p class="alert-danger">You must be registered to use this coupon.</p>';
extensions/cart_module/controllers/Cart_module.php
Remove Lines 185 to 211
Add following to line 185 (to 216)
public function coupon() { // _updateModule() method to update cart
$json = array();
if (!$json AND $this->cart->contents() AND is_string($this->input->post('code')))
{
switch ($this->input->post('action'))
{
case 'remove':
$this->cart->remove_coupon($this->input->post('code'));
$json['success'] = $this->lang->line('alert_coupon_removed'); // display success message
break;
case 'add':
if ($this->customer->isLogged()) { // if user is logged in accept coupon
if (($response = $this->cart_module_lib->validateCoupon($this->input->post('code'))) === TRUE) {
$json['success'] = $this->lang->line('alert_coupon_applied');
// display success message
} else {
$json['error'] = $response;
}
} else {
$json['success'] = $this->lang->line('coupon_register'); // if user is not logged in send message
}
break;
default:
$json['redirect'] = referrer_url();
break;
}
}
$this->output->set_output(json_encode($json)); // encode the json array and set final out to be sent to jQuery AJAX
}
