Notifications when someone is on the site

Question

Is there anyway to get notified when someone logs on to the site or is even just browsing the site? I would like to receive email notifications when this happens but I cannot seem to find anywhere to activate this feature.

Answer 1

You can trigger wp_mail() to send you an email when you have a visitor, although you may end up getting flooded with emails since it'll email you every time a page is viewed.

/**
 * Send an email with every visit.
 */
function wpse113069_email_me_every_visit() {
    wp_mail( '[email protected]', 'You had a visitor...', 'Yea, someone was on your site!' );
}

add_action( 'wp', 'wpse113069_email_me_every_visit' );

You can also use is_user_logged_in() to extend this to include the page/post, the date & time of the visit, etc., or to customize the notification based on if someone is logged in or is an anonymous visitor.

/**
 * Send a different email based on if a visitor is signed into the site.
 */
function wpse113069_email_me() {
    $msg = 'An anonymous visitor visited!';

    if ( is_user_logged_in() ) {
        $msg = 'A member visited!';
    }

    wp_mail( '[email protected]', 'You had a visitor...', $msg );
}

add_action( 'wp', 'wpse113069_email_me' );

Answer 2

function whoisWatchingMe(){
    $email = "[email protected]";
    wp_mail( $email, 'You had a visitor...', 'Woopty do!' );
}

add_action( 'wp_login', 'whoisWatchingMe' );

Answer 3

function set_mail_here() {
return 'text/html';
}

add_action( 'wp_login', 'notice_here' );

function notice_here() {
if( is_user_logged_in() ) {
return;
}
$to = '[email protected]';
$subject = 'Message';
$message = '<h1>Someone logged in.</h1>';

add_filter( 'wp_mail_content_type', 'set_mail_here' );
wp_mail( $to, $subject, $message ); 
remove_filter( 'wp_mail_content_type', 'set_mail_here' );
}
