I am creating a Facebook event through Graph API with the code below, and I get the following error.
Unable to create event: {"error":{"message":"(#100) An event cannot have an end time in the past.","type":"OAuthException"}}
Here is my code:
include_once("class.xhttp.php");
$access_token = $facebook->getAccessToken();
$data['post'] = array(
'access_token' =>$access_token,
'name' => 'test' ,
'description' => 'test',
'location' => 'test' ,
'street' => 'test' ,
'city' => 'test' ,
'privacy_type' => 'OPEN',
'start_time' => date('Y-m-d H:i:s', time()),
'end_time' => '2011-02-10 20:00',
);
$response = xhttp::fetch("https://graph.facebook.com/{$profile_id}/events", $data);
if($response['successful']) {
$var = json_decode($response['body'], true);
echo "<pre>";
print_r($var);
echo "</pre>";
$url = "https://www.facebook.com/event.php?eid={$var[id]}";
echo $url;
}
else {
$error = "Unable to create event: {$response[body]}";
echo $error;
}
What is the awry?
You are trying to create an event that goes from now to some day before now. Switch it around, make the end-date now and the start date whenever you want (before now). The end date has to be later than the start date. Did I understand your question?

I have tried to read content from a s3 object through the below code.
$content = $s3Client->getObject(
array(
'Bucket'=> $bucketName,
'Key' => $pathToObject,
'ResponseContentType' => 'text/plain',
)
);
And I got below response
GuzzleHttp\Psr7\Stream Object (
[stream:GuzzleHttp\Psr7\Stream:private] => Resource id #87
[size:GuzzleHttp\Psr7\Stream:private] =>
[seekable:GuzzleHttp\Psr7\Stream:private] => 1
[readable:GuzzleHttp\Psr7\Stream:private] => 1
[writable:GuzzleHttp\Psr7\Stream:private] => 1
[uri:GuzzleHttp\Psr7\Stream:private] => php://temp
[customMetadata:GuzzleHttp\Psr7\Stream:private] => Array
(
)
)
Any help will be appreciated to read object content in S3.
Actually its return Psr7\Stream object.
So if we need to get contents from PSR Stream we have to call getContents() method from the object.
<?php
$s3Client = new Aws\S3\S3Client(array(
'stats' => TRUE,
'http' => array(
'verify' => FALSE,
'connect_timeout' => 30
),
'version' => 'latest'
));
$result = $s3Client->getObject(array(
'Key' => $filename,
'Bucket' => $bucketName
));
echo $result['Body']->getContents();
//Also you can get metadata like this print_r($result['Body']->getMetadata());
Hope this will help someone who is actually using SDK version 3.

I am currently trying to upload photos to pages and groups through an app. I have these codes:
try
{
$facebook->setFileUploadSupport(true);
$args = array('message' => 'This is my image caption',);
$args['image'] = '#'.realpath('./uploads/terragarden1.png');
$response = $facebook->api('/GROUP_ID/photos/','POST',$args);
}
catch(FacebookApiException $e)
{
echo "Error: ".$e;
}
The value of $args['image'] would be something like this:
#/home/publica/public_html/AutoPost/uploads/terragarden1.png
The problem is that it throws an OAuthException: An unknown error has occurred. I don't quite know what to do with this kind of error.
Additional:
When I try to post image using the same code and just changing
$response = $facebook->api('/GROUP_ID/photos/','POST',$args);
into $response = $facebook->api('/me/photos/','POST',$args);, the image would successfully be posted on the user's wall. What might be the problem here?
This works fine for me on pages:
$attachements = array(
'access_token' => $page->getToken(),
'message' => $post_pub['title'],
'url' => 'http://site.com/images/your_image.png' );
try{
$result = $facebook->api('/'.$page->getIdFacebook().'/photos', 'POST', $attachements, function(){
});
}
catch(Exception $e){ }
Might want to try switching from 'image' to 'url'
I got the same issue.
There is a topic about it here: https://developers.facebook.com/bugs/1430985030446221?browse=external_tasks_search_results_527428908614f7c36099745
I've been tried to do this with js sdk, with the same error response.
i have put last 3 posts in web page , if user loged in he can add comment / like , problem is if user loged in and try add like or comment he is getting an permission error #200 , if i loged in i can add like or comment (application is for me) , am getting the all permission nedded from the user , so how can i give him permission to add like / comment.
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();
and if the user click on like button :
jQuery('ul.fb_list a').click(function(){
var comm_id = jQuery(this).attr("class");
jQuery.post('https://graph.facebook.com/'+comm_id+'/likes/',{
access_token : "<?php echo $access_token ?>"
});
});
Double check and make sure your variable comm_id is formated with both the user id of the person who posted the post, and then the id of the post itself, with an underscore in between, like this - USERID_POSTID. This is how facebook gives it you if you call to the graph api
$post_url = "https://graph.facebook.com/" . $user_id . "/posts?access_token=". urlencode($access_token);
Not sure if you're getting comm_id from another source or not. Also noticed in your code
access_token : "<?php echo $access_token ?>"
You forgot a semi-colon after the echo call. Should be this
access_token : "<?php echo $access_token; ?>"
Hope this helps. I see you're using a lot of jquery to do the like functionality. I like to stick w/ server side code for stuff like this, I feel that it's more stable for some reason.
This is how I did it. I have a like button like this -
echo '<div id="like_container-'.$i.'">
<div id="like_count">'.$num_likes.'</div>'
<div class="unliked"></div>
</div>';
and fb_Like() is an ajax call, something like this -
function fb_Like(post_id, token, num_likes, id){
$.ajax({
type: "GET",
url: "likepost.php",
data: 'id='+post_id+'&token='+token+'&likes='+num_likes,
success: function(html)
{
$("#like_container-"+id).empty().html(html);
}
});
}
And the likepost.php page is a script similar to the one on this page
Like a Facebook Post externally using Graph Api - example
This worked really well for me. It also let's me update the number of likes that the post has on the front end right above the like button if a like has been made. Good luck!
UPDATE
If you want to check if the user already likes a post, it's pretty simple w/ the facebook graph api
//Create Post Url
$post_url = "https://graph.facebook.com/" . $Page/User_id . "/posts?access_token=". urlencode($access_token);
//Get Json Contents
$resp = file_get_contents($post_url,0,null,null);
//Store Post Entries as Array
$the_posts = json_decode($resp, true);
foreach ($the_posts['data'] as $postdata) {
foreach ($postdata['likes']['data'] as $like){
if($like['id']==$user){
$liked=1;
}else{continue;}
}
if($liked==1){
//do something
}
}
This assumes that you already have a facebook user id for the logged in user, in this example, stored in the variable $user.
I want to build a FB app which posts messages to the walls of those registered for the app.
There are two setups:
One message to many people (1-many, could occur few times a day)
Many user-specific massages (1-1, but many of them, could occur few times a day for each user)
All in all; one user could get a few different updates on his wall per day, but it could affect many users (that's pretty much the whole point of my idea)
Into what extend is Facebook going to allow me to do this, and won't think I'll be spamming.
PS:
I've come along this post, which seems to have remained unsolved...:
Post on Multiple Friend's Wall
And this post, which doesn't make it clear for me whether my idea is something I should start or not ;)
Graph API post to wall limitation
You can use Facebook batch API to do what you intent.
You can get more information on Facebook batch request at: http://25labs.com/tutorial-post-to-multiple-facebook-wall-or-timeline-in-one-go-using-graph-api-batch-request/
$batchPost[] = array(
'method' => 'POST',
'relative_url' => "/{ID1}/feed?access_token={ACCESS_TOKEN_FOR_ID1}",
'body' => http_build_query($body) );
$batchPost[] = array(
'method' => 'POST',
'relative_url' => "/{ID2}/feed?access_token={ACCESS_TOKEN_FOR_ID2}",
'body' => http_build_query($body) );
$batchPost[] = array(
'method' => 'POST',
'relative_url' => "/{ID3}/feed?access_token={ACCESS_TOKEN_FOR_ID3}",
'body' => http_build_query($body) );
$multiPostResponse = $facebook->api('?batch='.urlencode(json_encode($batchPost)), 'POST');
I developed an app in my website http://www.cefozyt.com which can post links, message etc. to multiple facebook users wall & groups. I used :-
if($user){
// Proceed knowing you have a logged in user who has a valid session.
//========= Batch requests over the Facebook Graph API using the PHP-SDK ========
// Save your method calls into an array
$queries = array(
array('method' => 'GET', 'relative_url' => '/'.$user),
array('method' => 'GET', 'relative_url' => '/'.$user.'/friends'),
array('method' => 'GET', 'relative_url' => '/'.$user.'/groups'),
array('method' => 'GET', 'relative_url' => '/'.$user.'/likes'),
);
// POST your queries to the batch endpoint on the graph.
try{
$batchResponse = $facebook->api('?batch='.json_encode($queries), 'POST');
}catch(Exception $o){
error_log($o);
}
//Return values are indexed in order of the original array, content is in ['body'] as a JSON
//string. Decode for use as a PHP array.
$user_info = json_decode($batchResponse[0]['body'], TRUE);
$friends_list = json_decode($batchResponse[1]['body'], TRUE);
$groups = json_decode($batchResponse[2]['body'], TRUE);
$pages = json_decode($batchResponse[3]['body'], TRUE);
//========= Batch requests over the Facebook Graph API using the PHP-SDK ends =====
if(isset($_POST['submit_x'])){
if($_POST['message'] || $_POST['link'] || $_POST['picture']) {
$body = array(
'message' => $_POST['message'],
'link' => $_POST['link'],
'picture' => $_POST['picture'],
'name' => $_POST['name'],
'caption' => $_POST['caption'],
'description' => $_POST['description'],
);
$batchPost=array();
$i=1;
$flag=1;
foreach($_POST as $key => $value) {
if(strpos($key,"id_") === 0) {
$batchPost[] = array('method' => 'POST', 'relative_url' => "/$value/feed", 'body' => http_build_query($body));
if($i++ == 50) {
try{
$multiPostResponse = $facebook->api('?batch='.urlencode(json_encode($batchPost)), 'POST');
}catch(FacebookApiException $e){
error_log($e);
echo("Batch Post Failed");
}
$flag=0;
unset($batchPost);
$i=1;
}
}
}
if(isset($batchPost) && count($batchPost) > 0 ) {
try{
$multiPostResponse = $facebook->api('?batch='.urlencode(json_encode($batchPost)), 'POST');
}catch(FacebookApiException $e){
error_log($e);
echo("Batch Post Failed");
}
$flag=0;
}
}
else {
$flag=2;
}
}

i can do it via url:

EDIT:
I see now you are trying to use the PHP SDK. Perhaps something like the following will work for you (saw this on another stackoverflow question):
$parameters = array(
'app_id' => $facebook->getAppId(),
'to' => $facebookUserId,
'link' => '(required) The link to send in the message. (??)',
'redirect_uri' => 'URL_TO_REDIRECT_TO_AFTER_USER_CLICKS_SEND_OR_CANCEL',
'picture' => 'OPTIONAL_URL_TO_IMG--AUTOGENERATED BY LINK',
'name' => 'OPTIONAL_NAME_OF_MESSAGE/ARTICLE--AUTOGENERATED BY LINK',
'description' => 'OPTIONAL_DESCRIPTION_TEXT--AUTOGENERATED BY LINK'
);
$url = 'http://www.facebook.com/dialog/send?'.http_build_query($parameters);
echo '<script type="text/javascript">window.open('.json_encode($url).', "_blank", options, false);</script>';
