How To Check If a FACEBOOK ID is male or female - facebook

Question

I was wondering can we check the gender of the facebook users using the facebook ID..

Answer 1

Yes you can, use the Graph API to query a user, here is my object, as you can see, I have a property called gender, I believe this property can be hidden if the user has set it up as such, so never assume this is in the response...
This also requires the target user to have granted your application basic information access.
{
"id": "754124803",
"name": "Daniel Phillips",
"first_name": "Daniel",
"last_name": "Phillips",
"link": "https://www.facebook.com/daniel.j.p",
"username": "daniel.j.p",
"gender": "male",
"timezone": 0,
"locale": "en_GB",
"verified": true,
"updated_time": "2012-02-04T16:00:42+0000",
"type": "user"
}
If you simply want to test out this, then use the Graph API Explorer: https://developers.facebook.com/tools/explorer/

Answer 2

You didn't mention which SDK you use i assume you use PHP
below is the php code and i think if you can use any other SDK you can also able to use the
below code with some necessary changes and yes this code is work perfectly i tested this code before answer here :)
<?php
//get the user gender
$user_id = $facebook->getUser();
$user_profile = $facebook->api('/me','GET');
$user_gender = $user_profile['gender'];
echo "Gender: " . $user_gender;
?>
You need user_about_me permission if user gender is not public and you can also get user friends gender using friends_about_me permission if user friend set this public
below is the my authorization code you need to make some changes in your authorization code use the above code in scope
$auth_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($canvas_page) . ("&scope=email,read_stream,publish_stream,offline_access,publish_actions,user_about_me,fiends_about_me&response_type=token"
