I would like to know if it's possible to login on Facebook api without a callback URL.
What I want to do is really "simple":
- Login on Facebook.
- Post or Delete on the wall.
- Logout of Facebook.
This is my code for login and post:
$fb = new Facebook\Facebook([
'app_id' => 'xxxx',
'app_secret' => 'xxxx',
'default_graph_version' => 'v2.5',
]);
$helper = $fb->getRedirectLoginHelper();
$permissions = ['publish_actions'];
$loginUrl = $helper->getLoginUrl(null, $permissions);
echo 'Log in with Facebook!';
try {
$accessToken = 'xxxx';
//$accessToken = $helper->getAccessToken();
//echo 'Log in with Facebook!';
$linkData = [
'link' => 'http://www.desarrollolibre.net/blog/tema/50/html/uso-basico-del-canvas',
'message' => $model->value,
];
$response = $fb->post('/feed', $linkData, $accessToken);
$graphNode = $response->getGraphNode();
The problem here is that I have to specify the access token getting directly from developers app, because $accessToken = $helper->getAccessToken() returns nothing to me.
Any help will be appreciate.
You can't "auto-login", you have to implement a proper login process. If you want to automate things (and you really should not autopost, because that is not allowed), you need to store a User Access Token somewhere and use it later. You may want to use an Extended User Token for this, because the default one is only valid for 2 hours. The Extended User Token is valid for 60 days.
More information about Tokens and how to generate them:

Is it possible or not?
the following code is posting as I post the page. I want the page itself post things to the wall.

First of all, publish_stream is deprecated since many years. You really need to check out the Facebook docs, they state clearly that you need publish_pages and manage_pages to post "as Page".
That being said, that exact same question gets asked a LOT on Stackoverflow, so you can easily find a lot more information with the search function. In general, this is what you need to do:
Authorize the user with publish_pages and manage_pages
(Generate an Extended User Token)
Get a Page Token with /me/accounts
User that Page Token to post to the Page wall

I want to post activities from page tab app to my own facebook page. I referred many documents to post message to app.
My php code :
$GLOBALS["facebook"] = new \Facebook_Facebook(array('appId' => $facebook_app_id, 'secret' => $facebook_secret,));
$page_info = $GLOBALS["facebook"]->api("/pageid?fields=access_token");
print_r($page_info);die;
if (!empty($page_info['access_token'])) {
$args = array(
'access_token' => $page_info['access_token'],
'message' => 'TEST'
);
$postId = $facebook->api("/pageid/feed", "post", $args);
But pageinfo variable has only id. I'm not getting access_token. Any idea what else need to be done?
We need manage_pages permission which we can get it using https://www.facebook.com/dialog/oauth?client_id=client_app_id&client_secret=9ea3e2eff7c65b1fcf1a633da&redirect_uri=YOUR_REDIRECT_URL&scope=read_stream,publish_stream,offline_access,manage_pages.
After that using above code we will get access token which can be used to publish to our page
after get my posts in my web page , then if user login he can add like / comment to that post problem is am getting an error if any user try add like or comment
200 Permissions error
if i login in with my username and password i can make like or add comment !!
am sending like via :
jQuery.post('https://graph.facebook.com/'+comm_id+'/likes/',{
access_token : "<?php echo $access_token ?>"
});
CODE :
$facebook = new Facebook(array(
'appId' => '',
'secret' => '',
'cookie' => true,
));
$user = $facebook->getUser();
if ($user) {
if (session_id()) {
} else {
session_start();
}
$access_token = $facebook->getAccessToken();
//check permissions list
$permissions_list = $facebook->api(
'/me/permissions', 'GET', array(
'access_token' => $access_token
)
);
//check if the permissions we need have been allowed by the user
//if not then redirect them again to facebook's permissions page
$permissions_needed = array('publish_stream', 'read_stream', 'manage_pages');
foreach ($permissions_needed as $perm) {
if (!isset($permissions_list['data'][0][$perm]) || $permissions_list['data'][0][$perm] != 1) {
$login_url_params = array(
'scope' => 'publish_stream,read_stream,manage_pages',
'fbconnect' => 1,
'display' => "page",
'redirect_uri' => 'http://localhost/fb/index.php',
);
$login_url = $facebook->getLoginUrl($login_url_params);
header("Location: {$login_url}");
exit();
}
}
}else {
//if not, let's redirect to the ALLOW page so we can get access
//Create a login URL using the Facebook library's getLoginUrl() method
$login_url_params = array(
'scope' => 'publish_stream,read_stream,manage_pages',
'fbconnect' => 1,
'display' => "page",
'redirect_uri'=>'http://localhost/fb/index.php',
);
$login_url = $facebook->getLoginUrl($login_url_params);
//redirect to the login URL on facebook
header("Location: {$login_url}");
exit();
}
$logoutUrl = $facebook->getLogoutUrl();
which access token is for the user is loged in
Make sure you have the publish_stream permission for any user you want to be able to create posts for. Remember, creating a comment is still creating content.
Checkout the publish_stream permission on Facebook's permissions documentation
Enables your app to post content, comments, and likes to a user's
stream and to the streams of the user's friends. This is a superset
publishing permission which also includes publish_actions. However,
please note that Facebook recommends a user-initiated sharing model.
Please read the Platform Policies to ensure you understand how to
properly use this permission. Note, you do not need to request the
publish_stream permission in order to use the Feed Dialog, the
Requests Dialog or the Send Dialog.
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 been madly trying to get access token for my users since long. I read at many sites to get it somehow by using getSession() and getting access_token from it... it gives me undefined function error.. I googled that too and all solutions said to use the updated SDK but mine is updated and it still won't work... so I finally got another solution to getting access token but this seems to be giving same access token for all users... any idea where the problem lies? All users certainly can't have same token right?
$app_id = $facebook->getAppId();
$app_secret = $facebook->getApiSecret();
function callFb($url, $params)
{
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_POSTFIELDS => http_build_query($params),
CURLOPT_RETURNTRANSFER => true,
CURLOPT_VERBOSE => true
));
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$params=array('client_id'=>$app_id, 'type'=>'client_cred', 'client_secret'=>$app_secret);
$url = "https://graph.facebook.com/oauth/access_token";
$access_token = callFb($url, $params);
$access_token = substr($access_token, strpos($access_token, "=")+1, strlen($access_token));
The issue is that you are asking for type=client_cred, which tells Facebook that you don't want access token for a user, but an access token for the app. This is used for doing things like accessing insights, the realtime updates API, and public data. If you want to get user data, you should not be passing that flag.
If you really do want to roll your own access to the Graph API, you can certainly do that, following the instructions at https://developers.facebook.com/docs/authentication/ .
You say you're using the PHP SDK but I don't see any mention of it anywhere in your code.
The proper way is this:
<?php
require('facebook.php');
$fb = new Facebook(array('appId' => APP_ID, 'secret' => SECRET));
$user = $fb->getUser();
// if we have a valid user, we're logged in
if ($user)
{
// do stuff with the API using the $fb object
}
else
{
// redirect the user to the authentication page
header("Location: ".$fb->getLoginUrl());
}
