How to Add Custom Variables

  • I would like to add custom variables to the dataLayer. How can I do this?

    For example, I want to pull the country code from the current page URL and send it as a “country” variable. Is this possible?

    Hi,

    Thanks for your question!

    There is a constant defined with my plugin:
    GTM4WP_WPFILTER_COMPILE_DATALAYER

    You may use this to add a WordPress filter hook and add whatever you want to the data layer:

    function my_dl_content( $dl ) {
  $dl[ "myData" ] = "Something";

  return $dl
}
add_filter( GTM4WP_WPFILTER_COMPILE_DATALAYER, "my_dl_content" );

    However in your specific case I think there is no need to add such code to your site: you may simply create a Custom JavaScript Variable on the GTM UI where you can use a simple JS code to extract the country code:

    function() {
  var pu = {{Page URL}},
      pu_parts = pu.split( "." );

  if ( pu_parts.length > 2 ) {
    return pu_parts[0]; // return first subdomain
  } else {
    return "en"; // fallback default value
  }
}
