How do I order the friends list returned from the new Facebook Graph API?

You can get a list of friends of an authenticated user with:

https://graph.facebook.co开发者_StackOverflow社区m/me/friends

Anyone have any idea how to order the list by user name? Because it doesn't by default. There's nothing in the documentation.

we do this in several apps just by sorting in javascript.

function sortByName(a, b) {
    var x = a.name.toLowerCase();
    var y = b.name.toLowerCase();
    return ((x < y) ? -1 : ((x > y) ? 1 : 0));
}

var _friend_data = null
function lazy_load_friend_data(uid) {
  if (_friend_data == null) {    
    FB.api('/me/friends', function(response) {        
        _friend_data = response.data.sort(sortByName);
      }
    )
  }
}

Figured out a solution. Eventually, we'll probably be able to order graph results. For now, I'm just doing this (javascript). Assuming that I got "fb_uid" from my PHP session:

var friends = FB.Data.query("SELECT name, uid FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1={0}) ORDER BY name", parseInt(fb_uid));
friends.wait(function(rows){
    console.log(rows);
});

I think the whole OpenGraph API is still in a bit of a transitional stage from FB Connect. In any case, I would just do a good old order-by query in FQL, which you can still use. I can't imagine it will be too hard to change once the open graph way of doing this gets established.

This very good tutorial shows you how to do it:

http://thinkdiff.net/facebook/php-sdk-graph-api-base-facebook-connect-tutorial/

$fql    =   "select name, hometown_location, sex, pic_square from user where uid=xxxxxxxxxxxxxxx";
$param  =   array(
        'method'     => 'fql.query',
        'query'      => $fql,
        'callback'   => ''
);
$fqlResult   =   $facebook->api($param);

What is the problem if you do it on caller side. That means, after you get all friends from that graph API, you can put all of them into a sorted data structure and then display all of them:)

Using FQL in one call.

SELECT uid, name FROM user WHERE uid IN 
(SELECT uid2 FROM friend WHERE uid1 = me()) 
ORDER BY name ASC

for me a simple asort($friends); worked fine ;)

$friends = $facebook->api('me/friends');
foreach ($friends as $key=>$value) {
    sort($value);
    foreach ($value as $fkey=>$fvalue) {
      echo "<img src='https://graph.facebook.com/".$fvalue[id]."/picture' width='50' height='50' title='".$fvalue[name]."' />";     
    }
}

Building off of @MainSocial's answer, but sorting by last then first name, instead of first name only:

function sortByName(a, b) {
    var fn = function(x) { return x.name.toLowerCase(); };
    var ln = function(x) { return x.last_name.toLowerCase(); };
    if(ln(a) == ln(b)){
        if(fn(a) == fn(b)) {
            return 0;
        }
        return (fn(a) < fn(b)) ? -1 : 1;
    }
    return (ln(a) < ln(b)) ? -1 : 1;
}

function getFriendsList() {
    FB.api('/me/friends', {fields: 'name,id,last_name'}, function(response) {
        var friends = response.data.sort(sortByName);
        for (i=0; i<friends.length; i++) {
            $('body').append(friends[i].name + ' - ' + friends[i].id + '<br>');
        }
    });
}

getFriendsList()

private function _compareFacebookFriends($a, $b)
{
    return strcasecmp($a['name'], $b['name']);
}

public function sortFacebookFriendsArray(&$array)
{
    usort($array, '_compareFacebookFriends');
}

/* Add here $facebook's initialization. Use Facebook PHP SDK */
$fbFriends = $facebook->api('/me/friends');
sortFacebookFriendsArray($fbFriends);
