In WordPress, the default user profile page has only few contact field details such as AIM, Yahoo IM, Jabber, Google Talk and E-mail. Though there are quite a few it is definitely not complete without having the mighty Twitter, LinkedIn, Facebook and Google Profile. Here comes a simple piece of code to add those extra fields. You can extend this code and make many more contact fields.

Paste the below code in your theme’s functions.php file. Save changes.

function extra_contact_info($contactmethods) {
    $contactmethods['facebook'] = 'Facebook';
    $contactmethods['twitter'] = 'Twitter';
    $contactmethods['linkedin'] = 'LinkedIn';
    $contactmethods['gprofile'] = 'Google Plus Profile';
    return $contactmethods;
}
add_filter('user_contactmethods', 'extra_contact_info');

Hold on. One more tip is there. If you want to remove some contact fields such as Yahoo and AIM, then you can modify the code as shown below.

function extra_contact_info($contactmethods) {
    unset($contactmethods['aim']);
    unset($contactmethods['yim']);
    $contactmethods['facebook'] = 'Facebook';
    $contactmethods['twitter'] = 'Twitter';
    $contactmethods['linkedin'] = 'LinkedIn';
    $contactmethods['gprofile'] = 'Google Plus Profile';
    return $contactmethods;
}
add_filter('user_contactmethods', 'extra_contact_info');

The second and third lines starting with unset… does the removal work.
