在 WordPress 网站中使用 Google Analytics 跟踪登录事件

Question

I wish to track when a user log in their account in my WordPress website with GA4 (Google Analytics 4), so I used the hook 'wp_login', as you can see in the snippet below that I added to functions.php file, but it doesn't work. I tried the hook alone (to create a cookie) and it works fine and I tried the code inside the function 'gal' alone and it works fine.

add_action('wp_login', 'gal',90);
function gal(){
    echo "<script>dataLayer.push({event: 'login'});</script>";
}

yea... You should probably use cookies to do this. Something like:

    function set_logged_in_cookie(){
    if(is_user_logged_in() && !is_admin()){
        if(!isset($_COOKIE['logged_in_once'])) {
            setcookie( 'logged_in_once', true, DAY_IN_SECONDS, COOKIEPATH, COOKIE_DOMAIN );
            //push an event to GA
        ?>
        <script>
            window.dataLayer = window.dataLayer || [];
            window.dataLayer.push({
                'event': 'login'
            });
        </script>
    <?php
        }
    }
}

add_action('wp_footer', 'set_loggedin_cookie');
