Facebook API access outside of apps.facebook.com - facebook

I am attempting to build a website that utilizes facebook auth based setting created through facebook.com/developers
Can I access a user’s wall (to post), multi friend selector and other elements if the website is hosted outside of facebook.com (apps.facebook.com) realm?

Yes, you need to use graph api through php sdk, js sdk or your own legacy one

You must require special permissions to post user's wall. Use a standard api mechanism to get access_token from user. Make sure user accepted the application permissions requirements such as offline_access, publish_stream etc.
public function friend_off()
{
$home_view = 'offline';
$this->load->library('facebook',array(
'appId' => FACEBOOK_APP_ID,
'secret' => FACEBOOK_SECRET,
'cookie' => true,
));
$this->load->database();
$this->db->where('status', 'A');
$db_user = $this->db->get('users');
//$db_user = $this->db->where('access_pass',$val));
$row = $db_user->result();
//print_r($row);
//friends list
$post = array(
'from' => array(
'access_token' => '1302623452|1212291707|Dgz0FpB0wL0n5PYLy2x--5iGRVo',
'name' => 'Syama Varyar',
'id' => '100002653867222'
),
'to' => array(
'name' => 'Vishnu Jayendran',
'id' => '558987909'
),
'caption' => 'Test Caption',
'description' => 'Test Description',
'picture' => 'http://www.najeem.com/bird-2003.gif',
'message' => 'Test Message >> '. date('Y-m-d H:i:s'),
);
$friends = $this->facebook->api('/100002653867222/friends?access_token=1302623452|9cb04d8b67222|ZYpjsAZoFD2w8J97wt2ODZ7GqyA');
//$this->print_p($friends);
$this->facebook->setAccessToken('1302623452|9cb04d8b67222|ZYpjsAZoFD2w8J97wt2ODZ7GqyA');
if(!($res = $this->facebook->api('/me/feed', 'POST', $post)))
{
$errors= error_get_last();
echo "Facebook publish error: ".$errors['type'];
echo "<br />\n".$errors['message'];
}
}

Trying to post to facebook page with app but get "The user hasn't authorized the application to perform this action"

I am trying to write a script that will post an update to a facebook page timeline. I created an app and created a key for the app. I am using the code below:
require_once HOME_PATH . '/include/facebook/facebook.php';
$facebook = new Facebook(array(
'appId' => FACEBOOK_APP_ID,
'secret' => FACEBOOK_APP_SECRET,
'cookie' => true,
'scope' => 'publish_stream',
));
$user_id = $facebook->getUser();
$access_token = $facebook->getAccessToken();
$attachment = array(
'access_token' => $access_token,
'message' => 'this is my message',
'name' => 'name',
'link' => ROOT_URL . $blog_data['url'] . '.htm',
'caption' => $blog_data['title'],
'description' => $blog_data['title'],
);
if ($image = get_first_image($blog_data['body'])) {
$attachment['picture'] = $image;
}
$facebook->api(FACEBOOK_BLOG_PAGE . '/feed', 'post', $attachment);
i think this key is connected to the app and not to my user, so it sounds like i would have to grant the permission within facebook, but i have seen some other posts telling me that i need to do this in code. The examples aren't very clear.
I know similar questions have been asked but i haven't seen any clear answers yet. Can anyone please clarify this?
If you want to get user_id by this piece of code: $user_id = $facebook->getUser();
The first thing you need, is to login an user through a URL returned by $facebook->getLoginUrl(array('scope' => array('perm', 'perm2'))).
Also, notice, where I put permissions, which I require. Not into the Facebook class constructor, but into the method getLoginUrl.
And lastly, for posting into a page, you need publish_actions permission (not publish_stream).

upload and attach a photo to a facebook note

I am trying to attach a photo to a facebook note with the following code
$attachment = array(
'message' => 'photo caption',
'subject' => 'photo subject',
'id' => $note_id
);
$attachment[basename($file_path)] = '#' . realpath($file_path);
$result = $facebook->api('/notes', 'POST', $attachment);
which generates an error code: Uncaught OAuthException: (#100) Requires extended permission: create_note
note_id is holding a correct note_id which is created above with the following code:
$note = $facebook->api('/notes', 'POST', array(
'access_token' => $token,
'subject' => 'subject',
'message' => 'message'
));
$note_id = $note{'id'};
facebook note api reference https://developers.facebook.com/docs/reference/api/note/ doesn't provide much details on this task. plz help.

Post content to Facebook through the back end

Using PHP, can I post content to a Facebook page when I add something to my website? In this instance I'm creating a news post on our website but want to know if Facebook is capable of receiving the same content to display on our page?
You can use the Facebook php API to post on the Facebook page
$attachment = array(
'message' => '',
'name' => '',
'link' => '',
'description' => '',
'picture' => "",
'actions' => array( array(
'name' => 'Get Search',
'link' => 'http://www.google.com'
))
);
$pageid = '';
$facebook->api('/'.$pageid .'/feed?access_token='.$facebook->getAccessToken(),'post',$attachment);

Uncaught OAuthException: (#200) The user hasn't authorized the application to perform this action

I'm trying to post to my facebook group wall but I keep on getting the above error. Can anyone please tell me what I might be doing wrong here? I have checked the Facebook documentation but I still can't seem to fix it myself. My code is as follows:
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'perms' => 'offline_access, user_groups, publish_stream',
'cookie' => true
));
$result = $facebook->api(
'/xxxxxxxxxgroupid/feed/',
'post',
array('access_token' => $facebook->getAccessToken(), 'message' => 'Playing around with FB Graph..')
);
I think you need user_groups extended permission.
Use Try before, that sould work fine
try {
$params = array(
'message' => "Hurray! This works :)",
'name' => "This is my title",
'caption' => "My Caption",
'description' => "Some Description...",
'link' => "http://stackoverflow.com",
'picture' => "http://i.imgur.com/VUBz8.png",
);
$post = $facebook->api("/$user/feed","POST",$params);
echo "Your post was successfully posted to UID: $user";
}
catch (FacebookApiException $e) {
$result = $e->getResult();
}

Facebook OAuthException: Error validating application

I have a simple PHP page that is going to be used to post a message to my own wall.
I've obtained an offline_access token that has "read_stream" and "publish_stream" permissions.
define('FB_APIKEY', 'MY_APP_KEY');
define('FB_SECRET', 'MY_APP_SECRET');
define('FB_SESSION', 'MY_OFFLINE_TOKEN');
require_once('facebook.php');
try {
$facebook = new Facebook(FB_APIKEY, FB_SECRET);
$facebook->api_client->session_key = FB_SESSION;
$attachment = array(
'message' => 'some meesgae',
'name' => 'This is my demo Facebook application!',
'caption' => "Caption of the Post",
'link' => 'mylink.com',
'description' => 'this is a description',
'actions' => array(array(
'name' => 'Get Search',
'link' => 'google.com'
))
);
$result = $facebook->api('/me/feed?access_token=' . FB_SESSION,
'post',
$attachment);
var_dump($result);
} catch(Exception $e) {
echo $e;
}
When I run this, I get "OAuthException: Error validating application".
I confirmed that my offline token is good. When I go to https://graph.facebook.com/me?access_token=[MY_OFFLINE_TOKEN], it returns my public profile in JSON format correctly.
So, I'm thinking I'm doing something wrong with the API call somewhere but for the life of me I can't seem to figure it out. I've been wrestling with this issue for the last two days. Could someone please help! :(
You don't have APP ID here. And make calls like this:
require_once('facebook.php');
$facebook = new Facebook( array(
'appId' => 'APP_ID',
'secret' => 'APP_SECRET',
'cookie' => true
));
try {
$attachment = array(
'message' => 'some meesgae',
'name' => 'This is my demo Facebook application!',
'caption' => "Caption of the Post",
'link' => 'mylink.com',
'description' => 'this is a description',
'actions' => array(array(
'name' => 'Get Search',
'link' => 'google.com'
))
);
$attachment['access_token'] = $offline_access_token; // add it to the array
$result = $facebook->api('/me/feed', 'POST', $attachment );
var_dump($result);
} catch(Exception $e) {
// error_log( $e ); // should use something like this when in production
echo $e;
}
Untested, but should work. Let me know if it doesn't.
