Issues getting the Facebook PHP SDK to work on my application

I was making a facebook application in which i have to show news feeds of the user who is using it. I am using graph API to do this. The problem is that its not getting me feeds. I used it to show friends like this:

$friends = $facebook->api('/me/friends');

and it is working fine.

For news feeds i use this:

$feeds   = $facebook->api('/me/home');

it shows me an error:

Fatal error: Uncaught IDInvalidException: Invalid id: 0 thrown in 
/home/content/58/6774358/html/test/src/facebook.php on line 560

when i try to get Profile feed (Wall) by using this:

$feeds   = $facebook->api('/me/feed');

it shows me an empty array.

These API calls are showing me results in the graph API page but don't know why not working in my application.Can any one help me please.. My full code is as follows

require_once 'src/facebook.php';

// Create our Application instance. $facebook = new Facebook(array( 'appId' => 'xxxxx', 'secret' => 'xxxxx', 'cookie' => true, ));

$session = $facebook->getSession();
    $fbme = null;
// Session based graph API call.
if (!empty($session)){
    $fbme = $facebook->api('/me');
}
if ($fbme) {
     $logoutUrl = $facebook->getLogoutUrl();
     echo '<a href="'.开发者_StackOverflow$logoutUrl.'">Logout</a>';
}else{
    $loginUrl = $facebook->getLoginUrl();
     echo '<a href="'.$loginUrl.'">Logout</a>';
}
$friends = $facebook->api('/me/friends?access_token='.$session["access_token"]);
$feeds   = $facebook->api('/me/feed?access_token='.$session["access_token"]); 
print('<pre>Herere:');print_r($feeds);die;

Did you ask for the read_stream permission during authentication?

What type of Authentication / "Allow" process did you go through?

JavaScript SDK? Facebook PHP SDK? XFBML Login Button?

EDIT- Here are helpful link that will get you started up:

Facebook PHP SDK

Authentication Process

Building Apps on Facebook.com

These are all official docs in Facebook and github.

EDIT: Follow this step by step:

From your original code, look for:

$loginUrl = $facebook->getLoginUrl();

Change it to:

$loginUrl = $facebook->getLoginUrl(array('req_perms'=>'read_stream'));

Uninstall your application first from your account:

http://www.facebook.com/settings/?tab=applications

Then try it again to show new Allow pop-up

EDIT:

It's also about the arrangement of code in the if statements. Use this code:

<?php
require_once 'src/facebook.php';
$session = $facebook->getSession();
$fbme = null;

if($session){
    $fbme = $facebook->api('/me');
    $friends = $facebook->api('/me/friends');
    $feeds = $facebook->api('/me/feed'); 
    $logoutUrl = $facebook->getLogoutUrl();
    echo '<a href="'.$logoutUrl.'">Logout</a>';
    echo "<pre>".print_r($feeds,TRUE)."</pre>";
}else{
    $loginUrl = $facebook->getLoginUrl(array('req_perms'=>'read_stream','canvas'=>1,'fbconnect'=>0));
    echo '<script> top.location.href="'.$loginUrl.'"; </script>>';
}

Uninstall your app again from

http://www.facebook.com/settings/?tab=applications

and re-open the application

The Facebook PHP SDK should handle your access token for you, you don't need to append it to your graph API endpoint in you Facebook::api() call.

As @dragonjet pointed out, you need to request the read_stream extended permission from your FB User in order to get access to their feed. Though, the exception you pasted doesn't really match that kind of problem, and your request to /me/home doesn't throw a similar exception (or one about not having access).

I still think this is a permissions issue, so start here for trying to fix it. Here's an example of how to request the appropriate permission.

$facebook = new Facebook(array(
    'appId' => FB_APP_ID, //put your FB APP ID here
    'secret' => FB_APP_SECRET, //put your FB APP SECRET KEY here
    'cookie' => true
));

$session = $facebook->getSession();

if ($session)
{
    //check to see if we have friends_birthday permission
    $perms = $facebook->api('/me/permissions');
}

 //we do this to see if the user is logged & installed
if (empty($session) || empty($perms['read_stream']))
{
    //get url to oauth endpoint for install/login
    $loginUrl = $facebook->getLoginUrl(array(
        //put the URL to this page, relative to the FB canvas
        //(apps.facebook.com) here vvv
        'next' => 'http://apps.facebook.com/path_to_your_app/index.php',
        'req_perms' => 'read_stream'
    ));

    //use javascript to redirect. the oauth endpoint cant be loaded in an
    //iframe, so we have to bust out of the iframe and load it in the browser
    //and tell the oauth endpoint to come back to the fb canvas location
    echo "<script>window.top.location='{$loginUrl}';</script>";
    exit;
}

print_r($facebook->api('/me/home'));
print_r($facebook->api('/me/feed'));
