Need a bit of help creating a hook for Analytics latest script

Post by **14Steve14** » Thu Sep 19, 2024 3:35 pm

I have tried twice to copy and adjust a hook file to add in the latest Google tag and failed for some reason. Google seems unable to find the tag. If I add the tag directly into templates/override/components/template_top.php google can find the tag.

The tag needs to do in between the <head></head> tags

Starting right from the beginning where is the best place to add the following code.

Code: Select all

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=xxxxxx"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'G-xxxxxx');
</script>

Can someone point me in the right direction please.

listen_injectSiteStart
would seem to be a good one.

Therefore;

Code: Select all

<?php
// save this file at /includes/hooks/shop/siteWide/gtag.php

class hook_shop_siteWide_gtag {

  function listen_injectSiteStart() {
    
    $gtag = <<<EOJS
<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-xxxxxx"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'G-xxxxxx');
</script>
EOJS;

    return $gtag;
  }
}

You would want to change G-xxxxxx appropriately.

Thanks Gary.

With the supplied code I am now getting the following error in the store error logs.

[19-Sep-2024 18:20:12 Europe/London] PHP Parse error: Invalid body indentation level (expecting an indentation level of at least 2) in /home/####/####/includes/hooks/shop/siteWide/gtag.php on line 17

The error is breaking the website and showing a white page and a page not working error.

Line 17 as in the code supplied is

I read online that there should be no indent, which there isn't so I am totally confused by the error that says there should be.

Here is the code that I now have

Code: Select all

class hook_shop_siteWide_gtag {

  function listen_injectSiteStart() {
    
    $gtag = <<<gtag
<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-###"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', '###');
</script>
gtag;

    return $gtag;
  }
}

I used that module but it was not showing the latest data using the google tag.

PM me and let me know what issues you are having and I can have a look. Many are using this without issues.

First thing I would do is try using

<<<EOD

rather than

<<<gtag

Not tested

Yes, the <<<name syntax should be used only with names that do NOT appear in the quoted string. In this case, gtag appears in the quoted string so you can't use <<<gtag

That's why they tend to be nonsense strings EOS or EOJS -- because those are unlikely to appear in the string you're quoting.
