Can you do this?
'description' => (isset($user->bio) ? $user->bio : NULL)
سؤال
I have an authentication system for Facebook login in Laravel that works fine when a user with all of the properties logs in, but when a user doesn't have one of the properties filled out, it throws an error (for example):
Undefined property: stdClass::$bio
Here is the relevant code:
Facebook.php:
public function get_user_info(Token_Access $token)
{
$url = 'https://graph.facebook.com/me?'.http_build_query(array(
'access_token' => $token->access_token,
));
$user = json_decode(file_get_contents($url));
// Create a response from the request
return array(
'uid' => $user->id,
'nickname' => $user->username,
'name' => $user->name,
'first_name' => $user->first_name,
'last_name' => $user->last_name,
'gender' => $user->gender,
'email' => $user->email,
'birthday' => $user->birthday,
'location' => $user->location->name,
'description' => $user->bio, //the line giving trouble for a user
'friends' => 'https://graph.facebook.com/me/friends?fields=id&access_token='.$token->access_token,
'image' => 'https://graph.facebook.com/me/picture?width=200&height=200&access_token='.$token->access_token,
'urls' => array(
'Facebook' => $user->link,
),
);
}
Oauth2Controller.php:
if(is_null($check)) {
$fan = new Fan;
$fan->fbid = $user['uid'];
$fan->email = $user['email'];
$fan->first_name = $user['first_name'];
$fan->last_name = $user['last_name'];
$fan->gender = $user['gender'];
$fan->birthday = $user['birthday'];
$fan->age = $age;
$fan->city = $city;
$fan->state = $state_abbrev;
$fan->image = $user['image'];
$fan->friend_ids_url = $user['friends'];
$fan->friend_ids_unpacked = $friend_ids;
$fan->save();
$new = Fan::where('fbid', '=', $user['uid'])->first();
Auth::login($new);
return Redirect::to('fans/home');
}
How do I check that a user has these fields included with their profile, so I don't have this error get thrown? Thank you.
