Wordpress stores only the registration date for users. So what if your system needs to know the last login date for a user. Well there is no in-built functionality available to get this. But we can use login hook and a metadata to accomplish this.

First we need to add a function for this login hook. Lets say the function is “set_last_login”. This will be used to store the login time when a user will log in.

//associating a function to login hook
add_action(‘wp_login’, ‘set_last_login’);

//function for setting the last login
function set_last_login($login) {
  $user = get_userdatabylogin($login);

  //add or update the last login value for logged in user
  update_usermeta( $user->ID, ‘last_login’, current_time(‘mysql’) );
}

As we have stored the last login time, now we can have a function to get the same.

//function for getting the last login
function get_last_login($user_id) {
  $last_login = get_user_meta($user_id, ‘last_login’, true);

  //picking up wordpress date time format
  $date_format = get_option(‘date_format’) . ‘ ‘ . get_option(‘time_format’);

  //converting the login time to wordpress format
  $the_last_login = mysql2date($date_format, $last_login, false);

  //finally return the value
  return $the_last_login;
}

//get current user object
$current_user = wp_get_current_user();

//get the last login time by passing the user id to the above function.
echo get_last_login($current_user->ID);

We are done.
