I'm trying to insert Google Analytics into our backoffice, does anyone have found the good file to edit or a module for this ?
So far I tried with /admin/themes/templates/header.tpl but it failed sadly.
Did anyone achieved to do this ?
You have to edit two files :
For the login page : /admin/themes/default/template/controllers/login/header.tpl
For all others : /admin/themes/new-theme/template/header.tpl
Then just add literal in smarty template to escape the JS from being executed :
{literal}
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'UA-XXXXX-X'); // Replace your UA here
</script>
{/literal}
