Facebook scope PHP - php

Question

I'm trying to work with Facebook's default PHP website integration and authentication.
When a user logs in, I'm able to request permissions to get various information from the user.
This question is kind of old. Please take note of harkirat1892's comment.
"If someone using Facebook SDK v4.4 is stumbling across this question, the answer by Dhiraj won't >work in that case as there is a small change. You don't have to include redirect_uri in the array >passed to getLoginUrl.
As per v4.4, getLoginUrl should work like:
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'email,user_checkins, user_birthday'
)
);
The various scopes can be found here: Facebook permissions."
It was really easy to figure out how to do it with the JavaScript one, but I'm confused where to specify the scope in the PHP example.
Basically, I just want to request for permission to access their email & location and maybe some other information.
Here is the code I'm working with:
(It's modified slightly, but it is almost an exact match to what they had.)
<?php
define('YOUR_APP_ID', '---------');
define('YOUR_APP_SECRET', '------------');
//Uses the PHP SDK. Download from https://github.com/facebook/php-sdk
require 'facebook.php';
$facebook = new Facebook(array(
'appId' => YOUR_APP_ID,
'secret' => YOUR_APP_SECRET,
));
$FBUID = $facebook->getUser();
?>
<?php if ($FBUID) {
$userInfo = $facebook->api('/' + $FBUID); ?>
<?php $FBName = $userInfo['name'];?>
<!--
Welcome <? // = $userInfo['name'] ?> -->
<?php } else { ?>
<div id="fb-root"></div>
<fb:login-button></fb:login-button>
<?php } ?>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '---------------',
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
};
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>

Answer 1

This is how you typically specify scope in PHP (check the documentation):
$facebook = new Facebook(array(
'appId' => AppInfo::appID(),
'secret' => AppInfo::appSecret(),
));
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'read_stream,publish_stream,publish_actions,manage_pages,email,user_checkins',
'redirect_uri' => $redirectURI
)
);
I hope this helps.

The answer above is great but, Facebook just loves to change things up. The best answer checked off on this forum is for a version of Facebook SDK, which is out of date. Similar to the example above, here is how you would request permissions or a scope for version 5.0.
session_start();
$F = new \Facebook\Facebook([
'app_id' => 'app-id',
'app_secret' => 'app-secret',
'default_graph_version' => 'v2.8'
]);
$helper = $F->getRedirectLoginHelper();
$callBackUrl = "http://website.com/callBack.php";
$scope = array("email","user_likes");
$loginUrl = $helper->getLoginUrl($url,$scope);
Also, I noticed the answer above is a request for "user_checkins" which I believe is deprecated. The most current reference list of permissions is here.

Answer 3

If someone using Facebook SDK v4.4 is stumbling across this question, the answer by Dhiraj won't work in that case as there is a small change. You don't have to include redirect_uri in the array passed to getLoginUrl.
As per v4.4, getLoginUrl should work like:
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'email, user_checkins, user_birthday'
)
);
The various scopes can be found here: Facebook permissions.

I am getting same issue and got below solution. Might it help you :
Open your app in facebook developer console and then select app reviews section on left side.
Submit Items for Approval. Some permissions need to take approval from facebook before using.
