I am trying to write events like current user's ip, username, login time to a log file. I have built the functions in php using WordPress hooks for the various events but how to bring them all together to my log function i don't know. These are my codes:

global $active_user;

      /**
        * function to get loggedin user's username
        */
        add_action('init', 'log_file_setup');
        function log_file_setup(){

        $path = dirname(__FILE__) . '/log.txt';

        $file = fopen($path,"w+");
        $person = "John\n";


        file_put_contents($path, $person, FILE_APPEND );
        }

       /**
        * function to get loggedin user's username
        */

        function get_username(){

         if(is_user_logged_in()){
         $active_user = wp-get-current-user(); 
         $username = $active_user->login;

         return  $username;
         }
        }

       /**
        * function to get loggedin user's Role(s)
        */

        function get_userole(){

         if(is_user_logged_in()){
         $active_user = wp-get-current-user(); 

         // I have cast this into an array because the user may have multiple roles
         $userroles = ( array ) $active_user->roles; 
          return $userroles;
         }
        }

• You also have a typo in your function's name. Instead of wp-get-current-user() you must use wp_get_current_user(). – Johansson Commented Sep 17, 2019 at 16:00

If you set the WP_DEBUG* constants in your wp-config.php file:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
// prevents debugging messages from appearing in the browser

...then you should be able to use error_log() in your code, and your debugging messages will be saved in wp-content/debug.log. (You'll probably have to ensure that wp-content/debug.log exists and is writable by the server to make this work.)
