In your View

Publish the DataLayer in the view

Just call this method in your app layout before the closing HEAD tag.

DataLayer::publish();

It will print this entire HTML code in your layout

<script>
    dataLayer = dataLayer || [];
</script>

<script>
    dataLayer.push({foo:'bar',user_name:'John Doe',age:42,country:'Belgium'});
</script>

<!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','YOUR_GOOGLE_ID');</script>
<!-- End Google Tag Manager -->

Don't forget to call DataLayer::noScript() right after your BODY tag

DataLayer::noScript();

It will print the following :

<noscript><iframe src="//www.googletagmanager.com/ns.html?id=YOUR_GOOGLE_ID"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>

You can use an optional array to choose if you do not want to initialise the global JS object or/and the Google's GTM script

DataLayer::publish(['init' => false, 'script' => false]);

It will just print this

<script>
    dataLayer.push({foo:'bar',user_name:'John Doe',age:42,country:'Belgium'});
</script>

The DataLayer is reset after each call to the DataLayer::publish() method.

Others methods

Load the data from session

DataLayer::load();

Save the data in the session

DataLayer::save();

Clear the data in the session

DataLayer::clear();

Get the array data

DataLayer::getData();

Print the global JS object in the view

DataLayer::init();

It will print this in the HTML

<script>
    window.dataLayer = window.dataLayer || [];
</script>

Print the Google's GTM script in the view

The $google_id parameter is optional. If omitted, it will use the Google ID set in your .env file

DataLayer::script([$google_id = null]);

<!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','YOUR_GOOGLE_ID');</script>
<!-- End Google Tag Manager -->
