[Resolved] How to setup GA4 Analytics using different domain per language

Problem:
The client is trying to track data for both the primary English domain and the French domain separately in Google Analytics GA4, using a different domain per language in WPML settings.
Solution:
We recommend inserting the Google Analytics code into the site using a custom function with a filter hook to check the current language. Here's a step-by-step guide:

1. Add the following code to your theme's

   functions.php

   file:

add_action( 'wp_head', function(){
    $current_language = apply_filters( 'wpml_current_language', null );
?>
  
    <?php if( $current_language == 'fr'){?>
      
    <!-- GA code for FR language here -->
      
    <?php } elseif( $current_language == 'en'){?>
      
    <!-- GA code for EN language here -->
  
<?php } ?>
  
<?php
});

• Refer to the documentation for more information on how to get the current language with WPML.
