RE: [PHP] Images being uploaded in ASCII format
Hi Tom.
make sure you have ENCTYPE=multipart/form-data in the form tag
Thanks for the tip, but that's not the problem. My code is below, and
as you can see there is nothing in the code that would be causing this.
It has to be something in the server, and while there have been a few
posts to these lists about this problem, never a resolution for the
problem.
Here's the code:
?php
function handleupload()
{
if (is_uploaded_file($_FILES['userfile']['tmp_name']))
{
$realname = $_FILES['userfile']['name'];
if(copy($_FILES['userfile']['tmp_name'],
'/path/to/file/'.$realname))
{
echo 'br /'.$realname.' uploaded/font';
}
else
{
echo 'br /'.$realname.'could not be
uploaded/font';
}
}
else
{
echo 'br /Possible file upload attack: filename
'.$_FILES['userfile']['name'].'.';
}
}
?
html
head
titleFile Upload/title
/head
body
?php
if (isset($_POST['method']) $_POST['method'] == 'upload')
handleupload();
?
form ENCTYPE=multipart/form-data method=POST action=?php echo
$_SERVER['PHP_SELF']; ?
input type=hidden name=method value=upload
File:input type=file name=userfile size=35
input type=submit value=upload name=submit
/form
/body
/html
This is very standard code, yet the images are uploaded in ascii format.
Does anyone have any idea why this is happening? How can I for the http
uploads to auto-detect? I've looked through the entire php.ini and
httpd.conf files and I can't seem to find anything, and as I mentioned
above none of the previous posts on this topic have been resolved.
Anyone?
Thanks much in advance,
Pablo

Re: [PHP] Images being uploaded in ASCII format
Hi Pablo,
Could you explain what exactly you mean by transferred in ASCII mode? do
you find that cr/lf combinations are translated (there by corrupting
your image) or some other corruption takes place?
Have you opened the files with a hex editor to see the contents? I am
sorry if you have mentioned these before, i don't have the older
messages in this thread.

RE: [PHP] Images being uploaded in ASCII format
Hi Raditha. Thanks very much for your reply. I've not been having much
luck with this one.
This is how the images should appear:
http://web.unbc.ca/~gossep/sample_images/1.gif
http://web.unbc.ca/~gossep/sample_images/nav-02.jpg
And here is how they appear after being uploaded:
http://web.unbc.ca/~gossep/sample_images/1_uploaded.gif
http://web.unbc.ca/~gossep/sample_images/nav-02_uploaded.jpg
The results to me seem the same as if an image were FTPed in ascii mode
instead of binary mode (or auto-detect which would ultimately set the
mode to binary).
I just downloaded the XVI32 hex editor, but what should I be looking for
when I open the files and examine the contents?
Some other particulars to this situation:
I've tried uploading the same images through the demo site on the
company from which we purchased our editor (www.devedit.com) and they
upload fine, making me certain it's a system setting on my system
causing the problem.
My system is as follows:
Dell Precision 340 Workstation
RedHat 9.0
Apache 2.0
PHP 4.2.2
Thanks with your help, Raditha. Greatly appreciated.
Cheers,
Pablo

RE: [PHP] Images being uploaded in ASCII format
Something wrong is with your uploader program... look at this:
Content-Disposition: form-data; name=upload; filename=C:\Documents
and Settin
gs\gossep\Desktop\ewimages\1.gif
And if you look closer to the data in the file, you will see it has 2
GIF or something (GIF8 twice)... so yep, you have something really wrong
with your uploader.
