AOL file upload problem

Anon

I have a file upload program that allows people to upload jpg and gif images. However, it isn't working with AOL on the mac (I haven't test Win yet). The files become all corrupt when uploading through aol...any ideas?

BTW, check.php3 just checks the file for type and dimensions.

if ($aerial_type == "image/jpg" || $aerial_type == "image/jpeg") {
$extension = ".jpg";
} else {
$extension = ".gif";
}
if (copy($aerial,$basepath.$id."s".$extension)) {
$imageurl = $id."s".$extension;
include("check.php3");
if($error_msg){
$error_aerial == $error_msg;
$uploaderror = "1";
}
$aerial_value = "$imageurl";
} else {
echo("<b>Error: failed to copy file...</b>");
}
unlink($aerial);
}

Thanks for your help!

Hi,

I am trying to solve a similar problem and have found that the file types uploaded from a mac are sent as "application/x-macbinary" format.

So I think your files are not corrupt they are just being uploaded in mac binary.

I am not sure if the problem is because of image headers which I believe macs treat differently. So if anyone has any ideas please let me know.

This has been a real pain.
You can go into your browser preferences
and force the mac browser to upload the file as text. I've tried parsing out the info from x-macbinary and its not working, yet.

Any solutions?

sorry - no luck so far. you can load the stuff up but you can't do a thing with it. I have found that if an image is saved on a PC then a mac and a PC can upload it fine. But if an image was saved on a mac only the PC can load it up.

Only one person replied to me when I posted the problem and they were stumped too 🙁

Hi there....
the problem seems to be that when you upload a file format that the browser doesn't recognise, it tends to automatically class it as the mime type 'application/x-macbinary'

after looking at the files, i have come to the conclusion that with this standard MacBinary format (NOT the compressed version) all that is added is a simple header. this can be got rid of and the file can ran as normal.
try this little function out, it creates a temp file, whilst leaving the original intact for comparison (returns the new 'un-macced' filename)
function util_convertmacbin($filename) {
$fp = fopen($filename,'r');
fseek($fp,128);
$data = fread($fp,(filesize($filename)-128));
fclose($fp);
$newfile = tempnam ('/tmp', 'temp');
$fp = fopen($newfile,'w');
fwrite($fp,$data);
fclose($fp);
return $newfile;
}
