Looking to add Google Tag Manager code in your Oxygen-powered WordPress site?
Just add the following Snippet after installing and activating Code Snippets plugin:
add_action( 'wp_head', 'sk_google_tag_manager1', 1 );
/**
* Adds Google Tag Manager code in <head> below the <title>.
*/
function sk_google_tag_manager1() { ?>
<!-- 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=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-XXXXXX');</script>
<!-- End Google Tag Manager -->
<?php }
add_action( 'ct_before_builder', 'sk_google_tag_manager2' );
/**
* Adds Google Tag Manager code immediately after the opening <body> tag.
*/
function sk_google_tag_manager2() { ?>
<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-XXXXXX"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->
<?php }
Replace the code inside the above functions with the snippets provided by Google in the Tag Manager interface or replace GTM-XXXXXX with your container ID.
Set the snippet to load on the frontend.
