At times, you may need the functionality of showing last login date and time of users on WordPress Dashboard. As WordPress provide functions to get and set last login date and time, so you can easily save user’s last login date and time.

To achieve this functionality, you can use the following code in your Theme‘s functions.php file:

// set the last login date
add_action('wp_login', 'pt_set_last_login', 0, 2);
function pt_set_last_login($login, $user) {
    $user = get_user_by('login',$login);
    $time = current_time( 'timestamp' );
    $last_login = get_user_meta( $user->ID, '_last_login', 'true' );
    if(!$last_login) {
    update_user_meta( $user->ID, '_last_login', $time );
    } else {
    update_user_meta( $user->ID, '_last_login_prev', $last_login );
    update_user_meta( $user->ID, '_last_login', $time );
    }
}

// set the last login date

add_action('wp_login', 'pt_set_last_login', 0, 2);

function pt_set_last_login($login, $user) {

$user = get_user_by('login',$login);

$time = current_time( 'timestamp' );

$last_login = get_user_meta( $user->ID, '_last_login', 'true' );

if(!$last_login) {

update_user_meta( $user->ID, '_last_login', $time );

} else {

update_user_meta( $user->ID, '_last_login_prev', $last_login );

update_user_meta( $user->ID, '_last_login', $time );

}

// get last login date
function pt_get_last_login($user_id, $prev = null) {
    $last_login = get_user_meta($user_id);
    $time = current_time( 'timestamp' );
    if(isset($last_login['_last_login_prev'][0]) && $prev) {
        $last_login = get_user_meta($user_id, '_last_login_prev', 'true' );
    } else if(isset($last_login['_last_login'][0])){
        $last_login = get_user_meta($user_id, '_last_login', 'true' );
    } else {
        update_user_meta( $user_id, '_last_login', $time );
        $last_login = $last_login['_last_login'][0];
    }
    return $last_login;
}

// get last login date

function pt_get_last_login($user_id, $prev = null) {

$last_login = get_user_meta($user_id);

$time = current_time( 'timestamp' );

if(isset($last_login['_last_login_prev'][0]) && $prev) {

$last_login = get_user_meta($user_id, '_last_login_prev', 'true' );

} else if(isset($last_login['_last_login'][0])){

$last_login = get_user_meta($user_id, '_last_login', 'true' );

} else {

update_user_meta( $user_id, '_last_login', $time );

$last_login = $last_login['_last_login'][0];

}

return $last_login;

}

Additionally, you can display current login date/time and the last login date/time by using the following code:

// show last login date
global $current_user;
get_currentuserinfo();
echo '<p>Previous: Login date: '. date("Y-m-d h:m:s", pt_get_last_login ($current_user->ID, true)) . '</p>';
echo '<p>Current: Login date: ' . date("Y-m-d h:m:s", pt_get_last_login($current_user->ID)) . '</p>';

// show last login date

global $current_user;

get_currentuserinfo();

echo 'Previous: Login date: '. date("Y-m-d h:m:s", pt_get_last_login ($current_user->ID, true)) . '';

echo 'Current: Login date: ' . date("Y-m-d h:m:s", pt_get_last_login($current_user->ID)) . '';

Note: Just by adding true in pt_get_last_login($current_user->ID, true)), you can show the previous login date to your users.

In case if you want to display days since last login as compared to the current login date, use the following code:

// how many days since last login
global $current_user;
get_currentuserinfo();
$now = time();
$last_login = pt_get_last_login($current_user->ID, true);
$datediff = $now - $last_login;
echo '<p>Days since last login: ' . floor($datediff/(60*60*24)) . '</p>';

// how many days since last login

global $current_user;

get_currentuserinfo();

$now = time();

$last_login = pt_get_last_login($current_user->ID, true);

$datediff = $now - $last_login;

echo 'Days since last login: ' . floor($datediff/(60*60*24)) . '';
