Let me first thank you for allowing me to ask some question here. I hope you can help me with the following question.
I want to post some message on User's Facebook status. It is successful with the following code:
$params = array('access_token'=>$access_token, 'message'=>$message);
$url = "https://graph.facebook.com/".$fbuserid."/feed";
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_POSTFIELDS => $params,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_VERBOSE => true
));
$result = curl_exec($ch);
What do I need to add or do to post image and/or link affiliate to this post msg? Thank you!
In order to publish a photo to a user's album, you must have the publish_stream permission. With that grantedd, you can upload a photo by issuing an HTTP POST request with the photo content and an optional description to one these to Graph API connections:
https://graph.facebook.com/USER_ID/photos - The photo will be published to an album created for your app. We automatically create an album for your app if it does not already exist. All photos uploaded this way will then be added to this same album.
https://graph.facebook.com/ALBUM_ID/photos - The photo will be published to a specific, existing photo album, represented by the ALBUM_ID.
Example:
<?php
$app_id = "YOUR_APP_ID";
$app_secret = "YOUR_APP_SECRET";
$post_login_url = "YOUR_POST_LOGIN_URL";
$code = $_REQUEST["code"];
//Obtain the access_token with publish_stream permission
if(empty($code)){
$dialog_url= "http://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&scope=publish_stream";
echo("<script>top.location.href='" . $dialog_url
. "'</script>");
}
else {
$token_url="https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$access_token = $params['access_token'];
// Show photo upload form to user and post to the Graph URL
$graph_url= "https://graph.facebook.com/me/photos?"
. "access_token=" .$access_token;
echo '<html><body>';
echo '<form enctype="multipart/form-data" action="'
.$graph_url .' "method="POST">';
echo 'Please choose a photo: ';
echo '<input name="source" type="file"><br/><br/>';
echo 'Say something about this photo: ';
echo '<input name="message"
type="text" value=""><br/><br/>';
echo '<input type="submit" value="Upload"/><br/>';
echo '</form>';
echo '</body></html>';
}
?>
Sample Output:
{
"id": "1001207389476"
}

I got the code from the Facebook page to publish the Photo to the user's wall (account).
Below is my PostToFB.php file:
<?php
include_once "facebook.php";
ini_set("display_errors",0);
//configuring application to post.
$app_id = "YOUR_APP_ID";
$app_secret = "YOUR_APP_SECRET";
$post_login_url = "YOUR_REDIRECT_URL";
$code = $_REQUEST["code"];
//Obtain the access_token with publish_stream permission
if(empty($code)){
$dialog_url= "http://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&scope=publish_stream";
echo("<script>top.location.href='" . $dialog_url
. "'</script>");
}
else {
$token_url="https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$access_token = $params['access_token'];
// Show photo upload form to user and post to the Graph URL
$graph_url= "https://graph.facebook.com/me/photos?"
. "access_token=" .$access_token;
echo '<html><body>';
echo '<form enctype="multipart/form-data" action="'
.$graph_url .' "method="POST">';
echo 'Please choose a photo: ';
echo '<input name="source" type="file"><br/><br/>';
echo '<input type="submit" value="Upload"/><br/>';
echo '</form>';
echo '</body></html>';
}
?>
But this is not working. I get below Output:
{
"error": {
"message": "(#200) Permissions error",
"type": "OAuthException",
"code": 200
}
}
Can you please help me to solve this?
Thank You,
This code works absolutely fine. Only probably reason seems to me is that you have not granted the permission for the photo upload. Check which permissions you have granted to your app from here: https://www.facebook.com/settings?tab=applications
If still didnt helped, you can create a new app and try again; since this code is correct.
Edit:
publish_stream is deprecated, try using publish_actions
i am trying to post image to a facebook fun page, it's working will on my own wall but the fun page not and have no problem with posting text to fb fun page wall.
$photo_url = "http://www.google.com/logo.png";
$photo_caption = $text;
$code = $_REQUEST["code"];
//Obtain the access_token with publish_stream permission
if (!$code)
{
$dialog_url= "http://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&scope=publish_stream";
echo("<script>top.location.href='" . $dialog_url
. "'</script>");
}
else
{
$token_url="https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id
. "&client_secret=" . $app_secret
. "&redirect_uri=" . urlencode( $post_login_url)
. "&code=" . $code;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$access_token = $params['access_token'];
// POST to Graph API endpoint to upload photos
$graph_url= "https://graph.facebook.com/{FUNPAGE-ID}/photos?"
. "url=" . urlencode($photo_url)
. "&message=" . urlencode($photo_caption)
. "&method=POST"
. "&access_token=" .$access_token;
echo '<html><body>';
echo file_get_contents($graph_url);
echo '</body></html>';
}
what can i do i think it's about the graph_url
You need to provide the data as encoded binary of the image itself.
The URL parameter only adds a link to the POST as a part of the text or annotation, it will not retrieve and add the photo istelf from that URL!
add something like
...
"url=" . urlencode(file_get_contents($photo_url));
...
And: furthermore the Method must be POST, I'm not quite sure whether "file_get_contents" is going to POST the data and not just doing a GET as the name imposes.
I'm creating a FaceBook app where the user selects multiple images and the application generates a single image from them (PHP). I'm giving the generated image a semi-random name - $storage_url = $rack_directory . "rack_" . mt_rand() . mt_rand() . ".png"; (e.g. rack_2128639756968968165.png) and storing it temporarily as well.
I'd like the user to be able to upload the generated image to their Facebook profile directly from the page rather than downloading and then uploading it.
In looking over answers in this site as well as others it looks like I can use this:
$app_id = "YOUR_APP_ID";
$app_secret = "YOUR_APP_SECRET";
$post_login_url = "YOUR_POST-LOGIN_URL";
$album_name = 'YOUR_ALBUM_NAME';
$album_description = 'YOUR_ALBUM_DESCRIPTION';
$code = $_REQUEST["code"];
//Obtain the access_token with publish_stream permission
if(empty($code))
{
$dialog_url= "http://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode($post_login_url)
. "&scope=publish_stream";
echo("<script>top.location.href='" . $dialog_url .
"'</script>");
}
else {
$token_url= "https://graph.facebook.com/oauth/"
. "access_token?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$access_token = $params['access_token'];
// Create a new album
$graph_url = "https://graph.facebook.com/me/albums?"
. "access_token=". $access_token;
$postdata = http_build_query(
array(
'name' => $album_name,
'message' => $album_description
)
);
$opts = array('http' =>
array(
'method'=> 'POST',
'header'=>
'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = json_decode(file_get_contents($graph_url, false,
$context));
// Get the new album ID
$album_id = $result->id;
//Show photo upload form and post to the Graph URL
$graph_url = "https://graph.facebook.com/". $album_id
. "/photos?access_token=" . $access_token;
echo '<html><body>';
echo '<form enctype="multipart/form-data" action="'
.$graph_url. ' "method="POST">';
echo 'Adding photo to album: ' . $album_name .'<br/><br/>';
echo 'Please choose a photo: ';
echo '<input name="source" type="file"><br/><br/>';
echo 'Say something about this photo: ';
echo '<input name="message" type="text"
value=""><br/><br/>';
echo '<input type="submit" value="Upload" /><br/>';
echo '</form>';
echo '</body></html>';
}
...to generate a unique album and upload the picture...
But - I don't want to display a form that has a user browse to and upload (after they right/control click and save the image from the page). Just take the existing generated image displayed on the page and submit that.
Is there a function that I could use so that this process occurs and the only form requirement is to submit and upload?
Thanks.
What you need is the Facebook SDK :https://developers.facebook.com/docs/reference/php/
This makes all those "Graph" calls much simpler.
Pasting from that page:
// Load the facebook SDK
require_once("facebook.php");
$config = array();
$config['appId'] = 'YOUR_APP_ID';
$config['secret'] = 'YOUR_APP_SECRET';
$config['fileUpload'] = false; // optional
$facebook = new Facebook($config);
try {
$uid = $facebook->getUser();
catch (FacebookApiException $e) {
// Not logged on - you should log them on. Various methods, but redirect to $facebook->getLoginURL() is simplest. Docs: https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl/
}
Once the user is logged on, you can upload also through the SDK:
// Now upload the file
try {
$facebook->setFileUploadSupport('http://MyDomain.com/');
$response = $facebook->api(
'/me/photos/',
'post',
array(
'message' => 'Image Cpation',
'source' => '#/path/to/image' // #-sign must be the first character
)
);
}
catch (FacebookApiException $e) {
error_log('Could not post image to Facebook.');
}
You cna use an album ID in place of "me" for uploading directly to a specific album. But working your way through the SDK will help a lot more than trying it all manually with the graph calls!
Sorry, It's not a complete "here's the code" answer (there's still a bit of work to go), but that should help you upload without prompting the user.
I am using the following code it successfully upload video but after uploading it show some ID page. Can any one help how to redirect page to my desired location after uploading video successfully.
Thanks in advance.
$app_id = "YOUR_APP_ID";
$app_secret = "YOUR_APP_SECRET";
$my_url = "YOUR_POST_LOGIN_URL";
$video_title = "TITLE FOR THE VIDEO";
$video_desc = "DESCRIPTION FOR THE VIDEO";
$page_id = "YOUR_PAGE_ID";
$code = $_REQUEST["code"];
echo '<html><body>';
if(empty($code)) {
// Get permission from the user to publish to their page.
$dialog_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&scope=publish_stream,manage_pages";
echo('<script>top.location.href="' . $dialog_url . '";</script>');
} else {
$token_url = "https://graph.facebook.com/oauth/access_token?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$access_token = file_get_contents($token_url);
$accounts_url = "https://graph.facebook.com/me/accounts?" . $access_token;
$response = file_get_contents($accounts_url);
$resp_obj = json_decode($response,true);
$accounts = $resp_obj['data'];
foreach($accounts as $account) {
if($account['id'] == $page_id) {
$access_token = $account['access_token'];
break;
}
}
$post_url = "https://graph-video.facebook.com/" . $page_id . "/videos?"
. "title=" . $video_title. "&description=" . $video_desc
. "&access_token=". $access_token;
echo "<form enctype="multipart/form-data" action=" '.$post_url.' "
method="POST">";
echo "Please choose a file:";
echo "<input name="file" type="file">";
echo "<input type="submit" value="Upload" />";
echo "</form>";
}
You will have to make the video upload to facebook happen on your server side, instead of your visitors browser, so you can catch the output and send the visitors browser to the right place.
Your users will upload their files on your server first, then you can use curl to send the video to facebook, and after its finished you can redirect the user.
Examples:
Facebook Graph api video object: http://developers.facebook.com/docs/reference/api/video/

I am creating an app where the user can upload an image, that will be stored in apps profile page, and in the user profile. I'm using below code to do this work
<?php
$app_id = "XXXXXXXXXXXXXXXX";
$app_secret = "XXXXXXXXXXXXXXXXXXXXXXXX";
$post_login_url ="XXXXXXXXXXXXXXXXXXXXXXX";
$code = $_REQUEST["code"];
//Obtain the access_token with publish_stream permission
if(empty($code)){
$dialog_url= "http://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&scope=publish_stream";
echo("<script>top.location.href='" . $dialog_url
. "'</script>");
}
else {
$token_url="https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode( $post_login_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$access_token = $params['access_token'];
// first get your album id, let's assume you need to create it
// create this before hand and you can just reference the id
$attachment = array('access_token'=> ACCESS_TOKEN, 'name'=>$ablum_name);
try{
$album_resp = $facebook->api("/{$this->page_id}/albums", 'POST', $attachment);
}catch(Exception $e){
throw new Exception("Failed to create album: ". $e->getMessage());
}
$album_id = $album_resp['id'];
// Show photo upload form to user and post to the Graph URL
$graph_url= "https://graph.facebook.com/photos?"
. "access_token=" .$access_token;
echo '<form enctype="multipart/form-data" action="'
.$graph_url .' "method="POST">';
echo 'Please choose a photo: ';
echo '<input name="source" type="file"><br/><br/>';
echo 'Say something about this photo: ';
echo '<input name="message"
type="text" value=""><br/><br/>';
echo '<input type="submit" value="Upload"/><br/>';
echo '</form>';
}
?>
With this code it is going to the user's profile but not to the app's profile page. Can any one please tell what is wrong with it? Or is there another way to do it?
