Google Tag Manager 4

[websavers]

In case anyone wants to dive headlong into GTM 4 (as this doesn't support anything earlier), check out our module on GitHub: https://github.com/websavers/WHMCS-Google-Tag-Manager

As a developer GTM 4 is fantastic as the API for building events no longer feels like 7 different APIs hacked together with duplicate data everywhere. Granted its front end reporting tools can sometimes feel a bit weaker than the former enhanced analytics.

Open to pull requests.

This is exactly what was looking for!  I wasn't getting the view_item, etc to fire with the basic WHCMS setup. 😞 

But the add_to_cart doesn't seem to fire, I don't get any hits on that one.   I'm using the Lagom theme V2.1.2

Thanks!

Hey @FutureX

I took a look at the demo for the theme here: https://demo.rsstudio.net/lagom/cart.php?a=add&domain=register&rspage=default

Since it doesn't utilize an actual cart page, there's no way for the add to cart event to be triggered. Rather than a separate cart page, it immediately begins checkout with a cart review at the top of the checkout page, so that means add_to_cart would be one and the same with begin_checkout.

If you'd prefer it track checkout as an add_to_cart event, I'm afraid you'll need to modify the code found here: https://github.com/websavers/WHMCS-Google-Tag-Manager/blob/main/modules/addons/google_tag_manager/hooks.php

Under the viewcart  case on line 173, remove everything before the break; except these two lines:

        $event = 'add_to_cart';
        $action = 'viewcart';

That should then track begin_checkout events as add_to_cart events instead.

OK great, so I've modified it to this:

case 'viewcart':

        $event = 'add_to_cart';
        $action = 'viewcart';
     
      break;

 

Just tested it and it works! 

Thanks!

@websavers For some reason I'm not getting the amounts on Google Analytics. I get the number of purchases and what those purchases are for but no dollar amount.  Any way to fix that?

Thanks!

I'm afraid I have no idea why that would be the case; you'll need to troubleshoot the code to find out; try putting a bunch of logActivity() calls with the data you want to find out about in relevant points in the code and see what you can find.
