I am trying to obtain a random friend. I found this thread on SO and it looks it should work. Here is my code:<\/p>\n

            $config = array(\n                'appId'  => APP_ID,\n                'secret' => SECRET,\n                'cookie' => true,\n            );\n            $facebook = new Facebook($config);\n\n            $params = array(\n                'method' => 'fql.query',\n                'query' => \"SELECT uid, name, sex FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1=me()) order by rand() limit 1\",\n            );\n\n            $result = $facebook->api($params);\n            echo print_r($result);\n<\/code><\/pre>\n
But I am getting the error:<\/p>\n
Fatal error: Uncaught Exception: 102: Requires user session thrown in \/home\/path\/to\/base_facebook.php on line 1050\n<\/code><\/pre>\n
Where is the problem? I’ve tried to search possible problem, but I wasn’t much successful…<\/p>\n

  1. \n
    Yes, as Jason commented, looks like you’ve not got an authenticated user.<\/p>\n
    Since you’re using the PHP SDK, the quickest way to fix this is as follows<\/p>\n
    $config = array(\n    'appId'  => APP_ID,\n    'secret' => SECRET,\n    'cookie' => true,\n);\n$facebook = new Facebook($config);\n\n\/\/This will redirect the user to a login\/authentication dialog.\nif (!$facebook->getUser()) {\n    echo \"window.location = ' . $facebook->getLoginUrl() .'\";\n    exit();\n}\n\n$params = array().. etc, the rest of your code\n<\/code><\/pre>\n
    Lack of best practice code notwithstanding – That should do the trick<\/p>\n<\/li>\n<\/ol>\n
