Upload script returning blank data

Question

I have the Uploadify jQuery plugin set up on my site to manage file uploads. Within the onUploadSuccess event, I have this code:

'onUploadSuccess' : function(file, data, response) {
    console.log("Upload complete for file " + file.name + ". Script returned: " + data);
}

This is meant to show me whatever the upload script spits out. Now, usually the response is something like this:

Upload complete for file test.jpg. Script returned: {"status":1,"file":{"id":"v8rwlxj3","name":"test.jpg"}}

The upload script is first accepting the file, then uploading it to Rapidshare using cURL like so:

// Move uploaded file
move_uploaded_file($_FILES['Filedata']['tmp_name'], $targetDir . '/' . $id);

// Get the RapidShare server to upload to
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub=nextuploadserver');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
if(!$uploadServer = trim(curl_exec($ch))) {
    error('nextuploadserver failed');
}
if(strstr($uploadServer, 'ERROR:')) {
    error('nextuploadserver failed');
}

// Upload the file to RapidShare
$uploadID = mt_rand(1000000000, 9999999999);
$url = 'http://rs' . $uploadServer . '.rapidshare.com/cgi-bin/rsapi.cgi?uploadid=' . $uploadID;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
$postFields = array('sub' => 'upload',
                    'login' => 'login',
                    'password' => 'password',
                    'uploadid' => $uploadID,
                    'filename' => $_FILES['Filedata']['name'],
                    'filecontent' => '@' . $targetDir . '/' . $id);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
if(!$resp = curl_exec($ch)) {
    error('upload call failed');
}

when it's uploaded, the upload script spits out a JSON response like so:

// Output
echo json_encode(array('status' => 1, 'file' => array('id' => $id, 'name' => $uploadDetails[1])));

This works fine for smaller files. When I upload my 30MB test file however, I get this response:

Upload complete for file 30mb.txt. Script returned:

At first I thought PHP was hitting the max execution time, but I have this at the top of my script:

set_time_limit(21600); // 6 hours

And besides, I'd see the PHP error being returned. But it's just not returning anything. What could cause this? Thanks.

PHP may be not hitting time limit, but ajax may be reaching connection timeout while waiting for the response — dev-null-dweller, Jun 16 '12 at 20:47
Ah, that may be it. Uploadify assumes the upload was successful if it doesn't receive a response back from the script after 30 seconds. I'll set the success timeout to something high then see if it works. Thanks. — James Dawson, Jun 16 '12 at 22:21

Are you sure your upload_max_filesize is set to above 30M? That one has caused me some headaches in the past.

Yeah, the large files still get uploaded to Rapidshare and they're stored in my local directory so I know for a fact that the uploads are working. It just seems that the script is returning prematurely (the upload to Rapidshare is still running after the script has "returned"). – James Dawson Jun 16 '12 at 20:02

Remove uploadid post parameter. Uploadid parameter with resume upload.

Yes nice answer, although it was in comment but helped me. http://www.uploadify.com/documentation/uploadify/successtimeout/

set successTimeout to some high value. lets say 1 hour.
