I am super new to this so I apologize if this has a simple solution.
I've got a file running every 12 hours to search the database for new entries. If there is a new entry, it gets posted to the Facebook page. It works, but it only posts one entry even if two or more are in the query.
It might just be that I have the if statement in the wrong place, but I'm just stuck trying to figure it out.
I'd be grateful for any advice or link to tutorial.
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc() ) {
$linkData = [
'link' => $url,
'message' => 'Thank you for the positive review!' . "\r\n\r\n" . '"' . $row["review"],
];
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();
}
}

someone please help me. i'm trying to post a picture to the group but it's not working. Posts still appear on the group but no photos.
My code
$post_data = array(
'caption' => $mess,
'url' => $urlphoto
);
try {
$response = $fb->post('/944379269276566/photos', $post_data, $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;
}
this error occurs when you include a question mark (?) in the caption.
and this is a Facebook bug
https://developers.facebook.com/support/bugs/739380653703276/
After successfully signing up, i'm getting users Facebook pictures in this way
/*
* Get user profile picture
*/
try {
// Returns a `FacebookFacebookResponse` object
$response = $fb->get(
'/' .$fbUserProfile['id'] . '/picture',
$_SESSION['facebook_access_token']
);
} catch(FacebookExceptionsFacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(FacebookExceptionsFacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$avatar = $response->getHeaders()['Location'];
$this->model_account_customer->addCustomerAvatar($avatar, $this->customer->getId());
So far so good, but the pictures size is 50x50 :( . I read all similiar questions here, but none of them helped me. Also, i've tried to add type=large , i've changed the $response array like that
$response = $fb->get(
'/' .$fbUserProfile['id'] . '/picture',
$_SESSION['facebook_access_token'],
array(
'type' => 'large'
)
);
Still not working. Any ideas would be appreciated :)
I have the following script and would like to mention for ex. another page, which is involved in the post. I tried severall things, but can´ get it work. Isn´t it possible?
Here is my script:
header("Content-Type: text/html; charset=utf-8");
define('FACEBOOK_SDK_V4_SRC_DIR', __DIR__.'/src/Facebook/');
require_once(__DIR__.'/src/Facebook/autoload.php');
$fb = new Facebook\Facebook([
'app_id' => ‚1*************‘,
'app_secret' => ‚*e************,
'default_graph_version' => 'v2.2',
]);
$params["message"] = "Here is the magic - Thanks for your support, #[pageid]";
$params["link"] = "";
$params["picture"] = "";
$params["description"] = ";;
$pageAccessToken ='**************************';
try {
$response = $fb->post('/me/feed', $params, $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();
I tried, using #[pageid] and #[page-id:page-name], but both is not working.
Would be great to get any help.
From my experience, I will say error from facebook is always different based on configuration of your app, page etc. So it is difficult to say without seeing the exact error message. Just change your code a little bit to see error message is details:
try {
$response = $fb->post('/me/feed', $params, $pageAccessToken);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: '.$e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
var_dump($e);
exit;
}
I am sure, you will get error details which will guide you to solve your problem.
What I'm doing is creating a post with the Facebook PHP SDK(v4)(and the app is set to use the v2.3 API) with the privacy settings of value to SELF, then later on changing the value to CUSTOM, and allow to the ids of the friends that have accepted the app.
Until recently everything worked fine, and now out of the blue I'm getting this error(nothing changed on our part): "(#100) Object does not support message editing", which I couldn't locate in their documentation. Has anybody encountered this situation and this error?
Here is the code I'm using (like I said everything worked fine until recently)(if you need more details please let me know)
$fb_token = 'FB_TOKEN';
$FB_session = new FacebookSession($fb_token);
try {
$FB_session->validate();
} catch (FacebookRequestException $ex) {
// Session not valid, Graph API returned an exception with the reason.
//echo $ex->getMessage();
throw new RestException(501,'FB error: '. $ex->getMessage());
} catch (\Exception $ex) {
// Graph API returned info, but it may mismatch the current app or have expired.
//echo $ex->getMessage();
throw new RestException(501,'FB error: '. $ex->getMessage());
}
//make posting request to FB
if($FB_session) {
try {
$fb_array = array(
'privacy' => array(
'value' => 'CUSTOM',
'allow' => 'USER_ID'
)
);
$fb_req = new FacebookRequest(
$FB_session, 'POST', "/POST_ID", $fb_array
);
$response = $fb_req->execute()->getGraphObject();
//echo "Posted with id: " . $response->getProperty('id');
$fb_post_id = $response->getProperty('id');
} catch(FacebookRequestException $e) {
//echo "Exception occured, code: " . $e->getCode();
//echo " with message: " . $e->getMessage();
throw new RestException(501,'FB error: '. $e->getCode() .'-'. $e->getMessage());
}
}
I am new to the whole Facebook API.
I am creating a login page for users, and the idea is that they login with Facebook.
At the top of login page I have the following code:
$fb = new Facebook\Facebook([
'app_id' => "$fb_appid",
'app_secret' => "$fb_appsecret",
'default_graph_version' => 'v2.2',
]);
Then a little lower I have the login button:
if(isset($fb)){
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email']; // optional
$fb_login_url = $helper->getLoginUrl("$server_url/public/facebook/login-callback", $permissions);
} else $fb_login_url = "";
if(strlen($fb_login_url) >= 1) echo "<a href='$fb_login_url'><i class='fa fa-2x fa-facebook-square'></i></a>";
else echo "<a href='#' disabled='disabled'><i class='fa fa-2x fa-facebook-square'></i></a>";
The code works up until there, if I click the button, I go through to the Facebook portal, click the allow for the permissions and whatever, then it redirects me to login-callback.
The code on login-callback is:
if(isset($fb)){
$helper = $fb->getRedirectLoginHelper();
try {
$accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
} catch(Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
}
if (strlen($err_message) <= 0 && isset($accessToken)) {
$_SESSION['facebook_access_token'] = (string) $accessToken;
$fb->setDefaultAccessToken("$accessToken");
try {
$response = $fb->get('/me');
$userNode = $response->getGraphUser();
// $username = $userNode->getName();
// $firstname = $userNode->getFirstName();
// $lastname = $userNode->getLastName();
print_r($userNode);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
} catch(Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
}
}
}
The $userNode looks like this:
Facebook\GraphNodes\GraphUser Object
(
[items:protected] => Array
(
[name] => Jacques Koekemoer
[id] => xxxxxxxxxxxxxxxxxx
)
)
I have set the permissions to allow for the email, and if I am not mistaken the public profile is sent automatically.
I have also checked that the button on the login page does have "&scope=email". Below is the code that I have right on the page right now in the login button:
https://www.facebook.com/v2.2/dialog/oauth?client_id=xxxxxxxx&state=xxxxxxxx&response_type=code&sdk=php-sdk-5.0.0&redirect_uri=http%3A%2F%2Fxxxxxxx.xxxxxxxxxxxx.co.za%2Fpublic%2Ffacebook%2Flogin-callback&scope=email
I replaced the client_id, state and domain name because I don't want that information available publicly as I don't know what people can do with it.
Let me know if it is needed to solve the problem.
I used the Facebook guide here to setup and download the SDK.
I solved the problem.
You need to request specific fields from Facebook in the get function.
$response = $fb->get('/me?fields=id,name,email');
This can be found here.
A full list of fields that you can query can be found here.
Example
if (isset($fb)) {
$helper = $fb->getRedirectLoginHelper();
try {
$accessToken = $helper->getAccessToken();
} catch (Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
} catch (Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
}
if (strlen($err_message) <= 0 && isset($accessToken)) {
$_SESSION['facebook_access_token'] = (string)$accessToken;
$fb->setDefaultAccessToken("$accessToken");
try {
// this here is where you specify the fields
$response = $fb->get('/me?fields=id,name,email');
$userNode = $response->getGraphUser();
/* handle the result */
} catch (Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
} catch (Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
}
}
}
One of the my friend was trying to the issue from last 5 days. huummm very irritating. which got love in 2 min...
Assumption: using PHP for O2Authentication
Solution:
$loginURL = $fb->getLoginUrl({your redirect URL},['email']);
And job is done.
Thanks & Regards

Check you app version if it is version 2.2 or lower, it will work fine , it is not than it will not return. for that you have to request api with scope for email access.
