I need to run JavaScript on the successful order's page and get two things: order ID and total order amount. The code looks like:
<script type="text/javascript">
// Some code here
arr.push([
"create_order",
{order_id: "*order_id*", sum: *sum*}
]);
</script>
Questions
{order_id: "<?php echo $order_id; ?>", sum: <?php echo $product_total; ?>}
PS Opencart version is 1.5.6
The problem here is that on success page all the order data is already unset (deleted) from session variables. That's why your code cannot succeed.
Look into catalog/controller/checkout/success.php
and change the beginning of the index()
function to this:
public function index() {
$this->data['order_id'] = 0; // <-- NEW LINE
$this->data['total'] = 0; // <-- NEW LINE
if (isset($this->session->data['order_id'])) {
$this->data['order_id'] = $this->session->data['order_id']; // <-- NEW LINE
$this->data['total'] = $this->cart->getTotal(); // <-- NEW LINE
$this->cart->clear();
unset($this->session->data['shipping_method']);
unset($this->session->data['shipping_methods']);
unset($this->session->data['payment_method']);
unset($this->session->data['payment_methods']);
unset($this->session->data['guest']);
unset($this->session->data['comment']);
unset($this->session->data['order_id']);
unset($this->session->data['coupon']);
unset($this->session->data['reward']);
unset($this->session->data['voucher']);
unset($this->session->data['vouchers']);
}
$this->language->load('checkout/success');
Now you have the order_id
and cart's total
values stored in template variables, so just use them in your success.tpl
( not header):
<?php if($order_id) { ?>
<script type="text/javascript">
// Some code here
arr.push([
"create_order",
{order_id: '<?php echo $order_id; ?>', sum: '<?php echo $total; ?>'}
]);
</script>
<?php } ?>
This should be enough.
The previous answer needs to be updated for later versions of Opencart for 2.2.0
it is
$data['order_id'] = 0;
$data['total'] = 0;
and
$data['order_id'] = $this->session->data['order_id'];
$data['total'] = $this->cart->getTotal();
instead of the new lines indicated previously
