i have made an app which helps a user to post photos directly to a fb page from website.
the problem i am facing now is that if the access token expires i have to put new access token every time. i need a way to get a users access token automatically. is there any way? This is the code
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
require_once 'library/facebook.php';
$facebook = new Facebook(array(
'appId' => 'My_app_ID',
'secret' => 'My_App_secret',
'fileUpload' => true
));
#It can be found at https://developers.facebook.com/tools/access_token/
#Change to your token.
$access_token = 'CAAHkfWZB9T84BACm0LqdF1V5BFcppXZCHM7mrRxy9g8SRvw6Wz2RFZBMnYsdgsg413fIE5mpZChgYvz0DiJGGDUsVn8CKkZAFWvm6GHvcGw2xeD8EKH0D7MdkWrdNvD08oXabjzyfPsSTZCxfj1qPg40z4rFUQs8zSOIZD';
$params = array('access_token' => $access_token);
#The id of the fanpage
$fanpage = '232241216922182';
#The id of the album
$album_id ='281594988653471';
//here Wa33D94 is the id of the admin of the page where the photos will be uploaded
$accounts = $facebook->api('/Wa33D94/accounts', 'GET', $params);
foreach($accounts['data'] as $account) {
if( $account['id'] == $fanpage || $account['name'] == $fanpage ){
$fanpage_token = $account['access_token'];
}
}
$valid_files = array('image/jpeg', 'image/png', 'image/gif');
if(isset($_FILES) && !empty($_FILES)){
if( !in_array($_FILES['pic']['type'], $valid_files ) ){
echo 'Only jpg, png and gif image types are supported!';
}else{
$img = realpath($_FILES["pic"]["tmp_name"]);
$args = array(
'message' => 'This photo was uploaded via clixbox.net',
'image' => '@' . $img,
'aid' => $album_id,
'no_story' => 1,
'access_token' => $fanpage_token
);
$photo = $facebook->api($album_id . '/photos', 'post', $args);
if( is_array( $photo ) && !empty( $photo['id'] ) ){
echo '<p><a target="_blank" href="http://www.facebook.com/photo.php?fbid='.$photo['id'].'">Click here to watch this photo on Facebook.</a></p>';
}
}
}
?>
