Upload a photo on Facebook PHP SDK

Question

I'm making a website that users can upload photos to facebook via PHP Facebook api.

if a user attach a photo it should go to their album directly. It's weird that it used to work but now it's not working.

here's the code

$facebook->setFileUploadSupport(true);
$userPhoto  = $_FILES["pic"]["tmp_name"];

$fb_photoUpdate = $facebook->api('/$fb_id/photos/', 'post', array('source'=>'@'.realpath($userPhoto), 'message'=> 'photo uploaded successfully!'));

$fb_id is facebook user id. I save user's id in database when they first login on my website. Also, I save their access token.

I want to use &fb_id instead of /me. Is there any way to make this code work? Should I add access token there?

Please help me and Thanks in advance.

Plus, I've tried like this

$facebook->setFileUploadSupport(true); ?>

<script language="javascript">alert('1');</script>

<?php try { ?>
<script language="javascript"> alert('2');</script>
<?php   $fb_photoUpdate = $facebook->api('/$fb_id/photos/', 'post', array('source'=>'@'.realpath($userPhoto), 'message'=> $_POST['posting'])); ?>
<script language="javascript"> alert('3');</script>
<?php }

But, All I got was alert 1, alert 2. There was no alert 3 and also i didn't get any errors from console.

Answer 1

try changing $userPhoto = $_FILES["pic"]["tmp_name"]; to $userPhoto = $_FILES["pic"];

If not, are there any error codes you can share with us?
