Tracking Code For Google Tag Manager is a simple, lightweight WordPress plugin for inserting your Google Tag Manager tracking code. The plugin does one thing and one thing only; prints the standard Google Tag Manager tacking script to the <head> of your website. To insert your container ID, navigate to Settings > General and then scroll to the bottom of the page. Composer composer require claytoncollie/tracking-code-for-google-tag-manager Filters If you want to set the container ID without using the wp-admin user interface, use the filter below. add_filter( 'tracking_code_for_google_tag_manager_id', /** * Set Google Tag Manager container ID. * * @param string $container_id Container ID. * * @return string */ function ( $container_id ) { return 'GTM-7654321'; } ); Contributing While the purpose of this plugin is to be very tightly scoped, issues and pull requests are welcome, but I do not guarantee that everything will be merged or support will be given. https://github.com/claytoncollie/tracking-code-for-google-tag-manager
