[Resolved] Adding Google Analytics 4 tracking tags

Hi there, I spoke with Ilyes the other day about this.

Ilyes gave me this php to add to th html header;

<?php
// Determine the language (e.g., based on a language parameter in the URL)
$language = $_GET['lang'];

// Output the corresponding Google Analytics tracking code based on the language
if ($language == 'en') {
// English tracking code
echo "<script>Google Analytics tracking code for English</script>";
} elseif ($language == 'fr') {
// French tracking code
echo "<script>Google Analytics tracking code for French</script>";
} elseif ($language == 'es') {
// Spanish tracking code
echo "<script>Google Analytics tracking code for Spanish</script>";
}
?>

So for instance I have this google analytics infor for .ie;

Ireland Tag G-LW6VP1VQX6

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-LW6VP1VQX6');
</script>

Where it says;

echo "<script>Google Analytics tracking code for French</script>";

in the php, should this have the goog tag only i.e 'G-LW6VP1VQX6'

or should it have the whole script;

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-LW6VP1VQX6');
</script>

If neither what part of the information that I have from GA4 should I be adding here?

Hi Nicolas, Thank you fro getting back to me.

So for instance I'm using English and Italian.

From Google Analytocs 4 I have;

UK Tag G-6VNPELT58E

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-6VNPELT58E');
</script>

and

Italy Tag G-VVWGPYL9C6

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-VVWGPYL9C6');
</script>

Would the below be the correct way of implementing these within the PHP?;

add_action( 'wp_head', function(){
$my_current_lang = apply_filters( 'wpml_current_language', NULL );
if( $my_current_lang == 'en’ ){?>
<!-- Google tag (gtag.js) -->
<script async src="<u>hidden link</u>"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
 
gtag('config', '<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-6VNPELT58E');
</script>');
</script>
<?php } elseif( $my_current_lang == 'it’ ){?>
<!-- Google tag (gtag.js) -->
<script async src="<u>hidden link</u>"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
 
gtag('config', '<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-VVWGPYL9C6');
</script>');
</script>
<?php }
});

Hi Nico,

Thank you very much for your help. I appreciate it as PHP isn't my thing!

I hav addd the PHP using the Code Snippts plugin https://wordpress.org/plugins/code-snippets/. Do you thnk this will be ok or do I need to manually edit the functions.php file?

Cheers

John

Hi Nicolas, Thanks for gettin back to me. I've put it in the functions.php for the theme;

hidden link

I'm assuming that's the right place?

Also here is the PHP for the 5 versions of the site, does it look good to you?;

add_action( 'wp_head', function(){
$my_current_lang = apply_filters( 'wpml_current_language', NULL );

if( $my_current_lang == 'en' ){ ?>

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-6VNPELT58E');
</script>

<?php } elseif( $my_current_lang == 'it' ){ ?>

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-VVWGPYL9C6');
</script>

<?php } elseif( $my_current_lang == 'ga' ){ ?>

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-LW6VP1VQX6');
</script>

<?php } elseif( $my_current_lang == 'ar' ){ ?>

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-LW6VP1VQX6');
</script>

<?php } elseif( $my_current_lang == 'us' ){ ?>

<!-- Google tag (gtag.js) -->
<script async src="hidden link"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-RQM80S1S7N');
</script>

<?php }
});

Thanks again for all your help, hopefully the client will be happy at some point! 🙂

Hi Nicolas,

Thank you for getting back to me. I diod wonder about the languages. Should I use the hreflang for languages rather than code? (image attached)

Cheers

John

Can I keep this open for a little longer.

Thanks 🙂

Hi Nicolas,

I hope all's well.

Previously you mentioned that normally the codes for the USA would be 'en' and Britaing would be 'en_gb'. On the site the code is 'us' for USA and 'en' for GB.

Does this affect what a browser would detect? i.e in the US is a browser looking for a 'en_US' code? If it ses that the it has a 'en' could would it present the english site rather than the US version?

or are the codes just for internal use?

Cheers

John
