Question

How i can upload image or photo on Facebook Wall using Outh_key or access token without login using PHP?

Please help me & thanks a lot.

Answer 1

Here are some various ways to upload photos using the Graph API. The examples assume you’ve instantiated the $facebook object and have a valid session.

1 – Default Application Album of Current User

This example will upload the photo to your default application album of the current user. If the album does not yet exist it will be created.

$facebook->setFileUploadSupport(true);
$args = array('message' => 'Photo Caption');
$args['image'] = '@' . realpath($FILE_PATH);

$data = $facebook->api('/me/photos', 'post', $args);
print_r($data);

2 – Target Album

This example will upload the photo to a specific album.

$facebook->setFileUploadSupport(true);
$args = array('message' => 'Photo Caption');
$args['image'] = '@' . realpath($FILE_PATH);

$data = $facebook->api('/'. $ALBUM_ID . '/photos', 'post', $args);
print_r($data);

you can also specify this in the Facebook constructor:

$facebook = new Facebook(array( 'appId' => 'ID', 'secret' => 'SECRET', 'fileUpload' => true, 'cookie' => true));

Another Option

//upload photo
$file= '/path/filename.jpg';
$args = array(
   'message' => 'Photo from application',
);
$args[basename($file)] = '@' . realpath($file);
$ch = curl_init();
$url = 'http://graph.facebook.com/'.$album_id.'/photos?access_token='.$access_token;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
$data = curl_exec($ch);
//returns the photo id
print_r(json_decode($data,true));
