I want to programatically post a new story on a page I own. Do I need to ask Facebook for permissions to do that? When I invoke Facebook -> post I get an error: (#200) The user hasn't authorized the application to perform this action.
I wanted to request the publish_actions permission, but it seems to be permission for my app to post to app users' walls, which is not what I intend to do, I just want to publish on my own wall.
This is my code:
$fb = new Facebook\Facebook([
'app_id' => 'my app id',
'app_secret' => 'my app secret',
'default_graph_version' => 'v2.9',
'default_access_token' => 'the access token'
]);
$linkData = [
'link' => 'http://example.com/link/for/today',
'message' => 'This is the link for today',
];
try {
$response = $fb->post('/me/feed', $linkData);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
}
$graphNode = $response->getGraphNode();
echo 'Posted with id: ' . $graphNode['id'];
Thanks for any help!
To post to a page as the page, you will need permissions manage_pages and publish_pages, and you will need to get a page access token first ... and then use that to create the post.

Debug your Token: https://developers.facebook.com/tools/debug/accesstoken
You can see that it is a User Token, not a Page Token. Page Tokens can be generated by using a User Token with the following endpoints:
/me/accounts?fields=access_token
/page-id?fields=access_token
Make sure to use page token. You can easily get one from the the graphi api explorer on the right panel. I was having permissions error. My app type was business and to remove it, I just added all the permissions from the given list and after I added all permissions, facebook asked me to review permissions, I simply kept clicking on OK and everything worked, the error went :D
Cannot fetch E-Mail address from facebook SDK for some particular E-Mail accounts. The facebook account I am testing with do have their E-Mail address in facebook. I am having this issue for some particular accounts only. Is there any settings which I have to activate from facebook. To fetch E-Mail I am using PHP Facebook SDK, the code is listed below:
$fb = new Facebook\Facebook([
'app_id' => 'xxxxxxxxx',
'app_secret' => 'xxxxxxxxxxxxx',
'default_graph_version' => 'v2.11',
]);
try {
// Returns a `Facebook\FacebookResponse` object
$response = $fb->get('/me?locale=en_US&fields=id,name,email', $access_token);
} catch (Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch (Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$user = $response->getGraphUser();
echo '<pre>';
var_dump($user);
exit;
If I use artdarek/oauth-4-laravel I can fetch the E-Mail address for the exceptional cases as well. But as the project is live I cannot Install the same in live server. Please suggest an alternative way out with PHP Facebook SDK.
I'm using the tutorial here http://www.adamboother.com/blog/automatically-posting-to-a-facebook-page-using-the-facebook-sdk-v5-for-php-facebook-api/ to post to a facebook page using the PHP sdk.
I have create the app on Facebook, and I have created the Never Expire Page Access Token, which I have verified using the Access Token Debug Tool https://developers.facebook.com/tools/debug/accesstoken/
However, when I run my test code, it does NOT return any errors, but I get no posts on my page. I get a response back from my print_r($graphNode) of the following
Facebook\GraphNodes\GraphNode Object
(
[items:protected] => Array
(
[id] => 1204777049583245_1264619360265680
)
)
The code for my test post is below, can anyone explain to me WHY I am not getting any posts to show up?
define("FACEBOOK_APP_ID","MY APP ID");
define("FACEBOOK_APP_SECRET","MY APP SECRET");
define("FACEBOOK_APP_TOKEN","MY PAGE ACCESS TOKEN");
define("FACEBOOK_SDK_V4_SRC_DIR",$_SERVER['DOCUMENT_ROOT'].'/socialmedia/Facebook/src/Facebook/');
require_once($_SERVER['DOCUMENT_ROOT'].'/socialmedia/Facebook/src/Facebook/autoload.php');
$fb = new Facebook\Facebook([
'app_id' => FACEBOOK_APP_ID,
'app_secret' => FACEBOOK_APP_SECRET,
'default_graph_version' => 'v2.2',
]);
//Post property to Facebook
$linkData = [
'link' => 'www.yoururl.com',
'message' => 'test message'
];
$pageAccessToken = FACEBOOK_APP_TOKEN;
try {
$response = $fb->post('/me/feed', $linkData, $pageAccessToken);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: '.$e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: '.$e->getMessage();
exit;
}
$graphNode = $response->getGraphNode();
echo '<pre>';
print_r($graphNode);
echo '</pre>';
exit;
i am trying to post to my friends' feeds using this code, but it is not working . i am stuck, any help ??
$app_url ="http://localhost.local/PMS/facebook/PostWithPHP.php";
$facebook = new Facebook(array(
'appId' => 'APPID',
'secret' => 'APPSECRET',
'cookie' => true,
));
// Get User ID
$user = $facebook->getUser();
if ($user) {
$user_friends = $facebook->api('/me/friends');
sort($user_friends['data']);
try {
// Proceed knowing you have a logged in user who's authenticated.
$access_token = $facebook->getAccessToken();
$vars = array(
'message' => 'My Message',
'name' => 'title',
'caption' => 'Caption',
'link' => 'Link',
'description' => 'Description',
'picture' => 'image'
);
foreach($user_friends['data'] as $f){
$sendTo = $f['id'];
$sendToName = $f['name'];
$result = $facebook->api("/".$sendTo ."/feed", 'post', $vars);
}
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl(array('redirect_uri'=> $app_url));
echo "<script type='text/javascript'>";
echo "top.location.href = '{$loginUrl}';";
echo "</script>";
}
and another question is that using this code, but with replacing $facebook->api("/".$sendTo ."/feed", 'post', $vars); by $facebook->api("/me/feed", 'post', $vars); and of course without looping friends, posts on my timeline. how can i make it post on my wall ??
I guess for a post to a timeline you will need an accessToken from the user where to publish the content. In your case you just have the accessToken of the registered user, not of his friends. That is a restriction by FB I think.
1st check you getting the user id(place echo and check) if not try this... I think this will help you brother
$token_url = "https://graph.facebook.com/oauth/access_token?" ."client_id=" . $app_id ."&client_secret=" . $app_secret .
"&grant_type=client_credentials";
$access_token = file_get_contents($token_url);
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
$user_id = $data["user_id"];
There are a few things wrong with your code. First of all, make sure the link and picture parameters for the post are valid URLs. Facebook will give you a error message otherwise ((#100) link URL is not properly formatted). Also, the link must go to the Canvas or Site URL for your application.
That should solve the issues with posting to a friend's wall.
However, may I remind you that your application is in violation of the Facebook Platform Policy. Facebook doesn't allow multiple posts to the stream (whether its yours or a friends) unless there is explicit permission from the user. It also to stop common friends seeing the same message from multiple friends.
You can follow the tutorial here:
https://www.webniraj.com/2012/11/22/facebook-api-posting-a-status-update/
But, instead of making a API call to: /me/feed, you replace me with the friend's User ID, so it looks like /12345/feed
Please note that Facebook has now disabled posting to Friends' walls via the API. Instead, you should either tag the user in an action or use the Requests API.
I have a blog site written in php and it posts new blog posts to twitter and a blog ping automatically under the hood using simple http post requests passed using php curl.
I have a facebook page for the blog site and want the updates to be posted to the wall on the page, is there a simple way to do this?
What I really want is a url and set of params to parcel up as an http post request.
Note that this is to post to the wall on a new style page not a profile.
Get PHP SDK from github and run the following code:
<?php
$attachment = array(
'message' => 'this is my message',
'name' => 'This is my demo Facebook application!',
'caption' => "Caption of the Post",
'link' => 'http://mylink.com',
'description' => 'this is a description',
'picture' => 'http://mysite.com/pic.gif',
'actions' => array(
array(
'name' => 'Get Search',
'link' => 'http://www.google.com'
)
)
);
$result = $facebook->api('/me/feed/', 'post', $attachment);
the above code will Post the message on to your wall... and if you want to post onto your friends or others wall then replace me with the Facebook User Id of that user..for further information look out the API Documentation.
This works for me:
try {
$statusUpdate = $facebook->api('/me/feed', 'post',
array('name'=>'My APP on Facebook','message'=> 'I am here working',
'privacy'=> array('value'=>'CUSTOM','friends'=>'SELF'),
'description'=>'testing my description',
'picture'=>'https://fbcdn-photos-a.akamaihd.net/mypicture.gif',
'caption'=>'apps.facebook.com/myapp','link'=>'http://apps.facebook.com/myapp'));
} catch (FacebookApiException $e) {
d($e);
}
Harish has the answer here - except you need to request manage_pages permission when authenticating and then using the page-id instead of me when posting....
$result = $facebook->api('page-id/feed/','post',$attachment);
You can not post to Facebook walls automatically without creating an application and using the templated feed publisher as Frank pointed out.
The only thing you can do is use the 'share' widgets that they provide, which require user interaction.
If your blog outputs an RSS feed you can use Facebook's "RSS Graffiti" application to post that feed to your wall in Facebook. There are other RSS Facebook apps as well; just search "Facebook for RSS apps"...
You can make api calls by choosing the HTTP method and setting optional parameters:
$facebook->api('/me/feed/', 'post', array(
'message' => 'I want to display this message on my wall'
));
Submit Post to Facebook Wall :
Include the fbConfig.php file to connect Facebook API and get the
access token.
Post message, name, link, description, and the picture will be submitted to Facebook wall.
Post submission status will be shown.
If FB access token ($accessToken) is not available, the Facebook Login
URL will be generated and the user would be redirected to the FB login
page.
Post to facebook wall php sdk
<?php
//Include FB config file
require_once 'fbConfig.php';
if(isset($accessToken)){
if(isset($_SESSION['facebook_access_token'])){
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}else{
// Put short-lived access token in session
$_SESSION['facebook_access_token'] = (string) $accessToken;
// OAuth 2.0 client handler helps to manage access tokens
$oAuth2Client = $fb->getOAuth2Client();
// Exchanges a short-lived access token for a long-lived one
$longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
$_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;
// Set default access token to be used in script
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}
//FB post content
$message = 'Test message from CodexWorld.com website';
$title = 'Post From Website';
$link = 'http://www.codexworld.com/';
$description = 'CodexWorld is a programming blog.';
$picture = 'http://www.codexworld.com/wp-content/uploads/2015/12/www-codexworld-com-programming-blog.png';
$attachment = array(
'message' => $message,
'name' => $title,
'link' => $link,
'description' => $description,
'picture'=>$picture,
);
try{
//Post to Facebook
$fb->post('/me/feed', $attachment, $accessToken);
//Display post submission status
echo 'The post was submitted successfully to Facebook timeline.';
}catch(FacebookResponseException $e){
echo 'Graph returned an error: ' . $e->getMessage();
exit;
}catch(FacebookSDKException $e){
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
}else{
//Get FB login URL
$fbLoginURL = $helper->getLoginUrl($redirectURL, $fbPermissions);
//Redirect to FB login
header("Location:".$fbLoginURL);
}
