Multiple Gift Voucher Redemption

Hi Guys,
had a look through the forums and can't find this, I would have thought someone else might have had the same issue?
Using 1.5.2 and as it stands customers can only redeem one gift voucher per order, has anybody come up with a mod so customers can redeem as many gift vouchers as they happen to have? Would have thought the ability to redeem multiple gift vouchers would be standard functionality, understand that you want to limit coupons to just one per order just not gift vouchers or is it just me? Can see some customers potentially getting annoyed by this and what to have it sorted before going live.
Many Thanks

By default Opencart is using a single session variable voucher for calculating voucher so it will overwrite if you try to add more than one. The best way to customize this is by converting that variable into array and store each entered eligible voucher code into that array and instead of calculating single voucher code into shopping cart (catalog/module/total/vourcher.php) calculate all entered voucher codes discount.

Hi,
It's reasonably simple.
Modify catalog/controller/checkout/cart.php
Find this code:
Code: Select all
if (isset($this->request->post['voucher']) && $this->validateVoucher()) {
$this->session->data['voucher'] = $this->request->post['voucher'];
Replace with:
Code: Select all
if (isset($this->request->post['voucher']) && $this->validateVoucher()) {
$this->session->data['voucher'][$this->request->post['voucher']] = $this->request->post['voucher'];
Then modify catalog/model/total/voucher.php
Find this code:
Code: Select all
$this->load->model('checkout/voucher');
$voucher_info = $this->model_checkout_voucher->getVoucher($this->session->data['voucher']);
if ($voucher_info) {
if ($voucher_info['amount'] > $total) {
$amount = $total;
} else {
$amount = $voucher_info['amount'];
}
$total_data[] = array(
'code' => 'voucher',
'title' => sprintf($this->language->get('text_voucher'), $this->session->data['voucher']),
'text' => $this->currency->format(-$amount),
'value' => -$amount,
'sort_order' => $this->config->get('voucher_sort_order')
);
$total -= $amount;
And replace with
Code: Select all
$this->load->model('checkout/voucher');
foreach (array_unique($this->session->data['voucher']) as $voucher) {
$voucher_info = $this->model_checkout_voucher->getVoucher($voucher);
if ($voucher_info) {
if ($voucher_info['amount'] > $total) {
$amount = $total;
} else {
$amount = $voucher_info['amount'];
}
$total_data[] = array(
'code' => 'voucher',
'title' => sprintf($this->language->get('text_voucher'), $voucher),
'text' => $this->currency->format(-$amount),
'value' => -$amount,
'sort_order' => $this->config->get('voucher_sort_order')
);
$total -= $amount;
}
You'll also need to go into the template for the checkout.cart.tpl (depending on if you are using a custom one or the default) and remove the echo $voucher code from the input field i.e.
Code: Select all
<input type="text" name="voucher" value="<?php echo $voucher; ?>" />
becomes
Code: Select all
<input type="text" name="voucher" value="<?php //echo $voucher; ?>" />
Kind regards, Spencer

Hey Spencer,
many thanks for looking at this and providing a fix, website building has stalled for the moment as I'm prepping for a big assessment, but looking forward to getting back to work on the website with one less thing to sort : )

Could the same process be applied to coupons instead of vouchers? The code looks very similar between them, but its also just enough off that I could not just replace the word Voucher with Coupon in all instances.
If you have the time to post the code to do it with coupons I would be grateful. If you are too busy, I would be willing to pay for your services.

Well, this not worked in my test Opencart 1.5.3 but I found working solution as well.
You need first set $voucher into array:
Code: Select all
$this->load->model('checkout/voucher');
$voucher = array();
foreach (array_unique($this->session->data['voucher']) as $voucher) {
$voucher_info = $this->model_checkout_voucher->getVoucher($voucher);
if ($voucher_info) {
if ($voucher_info['amount'] > $total) {
$amount = $total;
} else {
$amount = $voucher_info['amount'];
}
$total_data[] = array(
'code' => 'voucher',
'title' => sprintf($this->language->get('text_voucher'), $voucher),
'text' => $this->currency->format(-$amount),
'value' => -$amount,
'sort_order' => $this->config->get('voucher_sort_order')
);
$total -= $amount;
}

Hi I've been looking at extensions as I'm not familiar with coding. Can anyone suggest one that will allow the customer to enter 2 voucher codes in 1 order. Say 10% off one product group and 15% off another.
