Tracking last login and last visit

1. You could create a new entry for the user meta data and update it on every admin pageload.

   Put the following in your theme’s functions.php or maybe wrap it into a plugin:

   function update_last_action_time() {
       $user = wp_get_current_user();
       update_user_meta($user->ID, 'last_action_time', current_time('mysql'));
   }
   add_action('admin_init', 'update_last_action_time');
   

   Of course, you could refine this (and thus lower the overhead) by restricting this to certain pages, for instance, the dashboard only.

   // Edit: you should use update_user_meta instead of the deprecated update_usermeta.

   // Edit, again

   In case you want to track users on the front-end, put this code in your desired template:

   if (is_user_logged_in()) {
       $user = wp_get_current_user();
       update_user_meta($user->ID, 'last_action_time', current_time('mysql'));
   }
   

   Again, to lower the overhead, I’d prefer putting this not into the footer.php file. I’d rather take home.php (if you have one), or check for particular requests (e.g., your home page, meaning: home_url() == 'http://'.$_SERVER['SERVER_NAME']). But as said before (meaning: below ;)), the overhead is, of course, okay when using it nonetheless in footer.php.

2. Try the following code which creates a function display_last_login that retrieves the current user’s ID, fetches the last login timestamp from the transient storage, and displays it on the screen.

   function display_last_login() {
   $user = wp_get_current_user();
   $user_id = $user->ID;
   $last_login = get_transient( 'user_last_login_' . $user_id );
   if ( false === $last_login ) {
       $last_login = __( 'Never', 'textdomain' );
   } else {
       $last_login = date( 'j F Y, H:i:s', $last_login );
   }
   echo '<p>Last Login: ' . $last_login . '</p>';
   

   }
   add_action( ‘wp_login’, ‘set_user_last_login’ );
   function set_user_last_login( $user_login ) {
   $user = get_user_by( ‘login’, $user_login );
   $user_id = $user->ID;
   set_transient( ‘user_last_login_’ . $user_id, time() );
   }
