$order_summary values not showing up on checkout success

**ehdesign** · 2 Feb 2017, 05:28 PM

I'm having trouble TAGGING on checkout success.

Here's what I have for code:

Code:

<!-- CHECKOUT SUCCESS TAGGING -->


<script type="text/javascript">
tagging.event("order", {
  action: "purchase",
  order: {
    order_id: " <?php echo $order_summary['order_number']; ?>",
    total: <?php echo $order_summary['order_total']; ?>,
    discount: <?PHP echo $order_summary['credits_applied']; ?>,
    subtotal: <?PHP echo $order_summary['order_subtotal']; ?>,
    tax: <?PHP echo $order_summary['tax']; ?>,
    shipping: <?PHP echo $order_summary['shipping']; ?>,
    coupon_code: "<?PHP echo $order_summary['coupon_code']; ?>",
    items: [
    <? for ($i=0, $n=sizeof($order->products); $i<$n; $i++) { ?>
      {
        product_id: "<?php echo $order->products[$i]['id']; ?>",
        price: <?php echo $order->products[$i]['final_price']; ?>,
        quantity: <?php echo $order->products[$i]['qty']; ?>,
        subtotal: <?php echo ($order->products[$i]['final_price']*$order->products[$i]['quantity']); ?>
      }
      <? if ($i == $n-1) {} else { echo ",";} ?>
      <? } ?>
    ]
  }
});
</script>


<!-- END tagging-->

I have this saved in a file:

/includes/modules/pages/checkout_success

BUT, here's what gets outputted:

Code:

<!-- CHECKOUT SUCCESS TAGGING -->


<script type="text/javascript">
tagging.event("order", {
  action: "purchase",
  order: {
    order_id: " ",
    total: ,
    discount: ,
    subtotal: ,
    tax: ,
    shipping: ,
    coupon_code: "",
    items: [
          {
        product_id: "168",
        price: 3.5000,
        quantity: 2,
        subtotal: 0      }
      ,            {
        product_id: "167",
        price: 5.7000,
        quantity: 1,
        subtotal: 0      }
                ]
  }
});
</script>


<!-- END tagging-->

Notice that NONE of the $order_summary values are populated.

I followed the details on this page:
https://www.zen-cart.com/content.php...els-to-my-site

Any help?

Since trying to use option 1.a) from the referenced document:

What is the actual name of the file in that location? Does it begin with jscript_ and end with (have the extension of) .php?

**ehdesign** · 2 Feb 2017, 08:27 PM

Bad copy and paste - I thought I included the actual file name:

jscript_zaius_checkoutSuccess.php

SO... YES it starts with jscirpt and YES it is a PHP file.

And I know the file is included and working as it is successfully outputting item in the order using the $order->products[$i] variable...

Just $order_summary isn't working as it is supposed to work?

What version of ZC?

Could maybe try adding at the top of your file:

Code:

<pre><?php echo print_r($order_summary, true); ?></pre>

**ehdesign** · 2 Feb 2017, 08:53 PM

If I change this line:

Code:

 order_id: " <?php echo $order_summary['order_number']; ?>",

to

Code:

 order_id: "7",

the 7 (or whatever random charaacter) shows just fine.... It's just the PHP $order_summary....

ANy ideas waht I am missing.?

Zen Cart v1.5.5d

I coudl try print_r or even var_dump the $order_summary variable, but that requires an order and I was just hoping to avoid having too many extra orders to cancel.

Are you "refreshing the page"? or are you using Chrome, which implicitly refreshes the page when showing Page Source in another tab?

The $order_summary data is intended to output only once: the first time the customer hits that page, so that it doesn't send multiple notices to external services. You wouldn't want to pay commissions to affiliates if the customer sat there refreshing the Success page 20 times, to rack up your payments due. (Ya, I know, "they" should ignore duplicates. Many do. Some don't.)

Instead of refreshing the page, right-click and use the Inspector. The output this generates is part of the <body> (not the <head>) section.

FWIW I used your code on a test site here and it works fine: I got all the order summary data properly.

One caveat: Depending on your PHP version, you probably wanna get in the habit of ALWAYS using <?php and NEVER just <?
Using <? is bad practice, and in newer versions of PHP will cause the section to be ignored.
So, change those 3 occurrences of <? to <?php and you're good to go.

I am using Chrome....

So, the page loads, then I am using VIEW SOURCE - view source seemed easier since I wanted to find a few different occourences of different JS.

TO repeat - using VIEW SOURCE would refresh the page and create empty variables where I used $order_summar, but NOT where I used $order->products[$i]

The $order_summary values were just plain empty.

But the $order->products[$i] values were filled in in the VEIW SOURCE.

???

If you follow the code of includes/modules/pages/checkout_success/header_php.php you will see that $data_summary is generated from the $_SESSION. Then after the data is collected, the seesion variable is cleared. Reloading the page (ie using the view source option described above with Chrome) will attempt to assign the values to the now empty session... but... the $order data is regenerated however often the page is loaded/reloaded with an exception that if the customer also somehow makes yet another purchase while the screen is up, then refresh (view source) will likely show the latest data (there are notes in the code about this).

So... to test/see what you want, you need to either use an alternate means to look at the output, or you need to make the output more readily visible. Pick something.

Yes. Exactly.
As mc12345678 explained, the $order_summary data is available only once.

And in reality, that's never a problem for the customer.

It's only a pain when doing dev stuff. Not much of an issue if you have an offline copy of the site to test on during development.

If you really want to change that, you can comment-out the unset($_SESSION['order_summary']) line in includes/modules/pages/checkout_success/header_php.php
I suggest you put it back to normal before you go live with it in production.
