Hi,

Trying to do a file uplaod and keep the extension. Unforntunately I can only upload text files - any idea why?

$email_user is a variable contain username
$userfile is from the form

/* File Upload in Start */
$today = date("YmdGis");
$pieces = explode(".", $_FILES['userfile']['name']);
$ext = $pieces[count($pieces) - 1];  
$filename = "$email_user$today.$ext";
$uploaddir = '../uploads/';
$uploadfile = $uploaddir . $filename ;
if (is_uploaded_file($userfile)) {
  (move_uploaded_file($userfile, $uploadfile));
}
/* end file upload */

Thanks,

Farawayman

regardless of the extension, that won't work.
see my little example.

$pieces = explode(".", "asdf.foo.bar.txt");
$ext = $pieces[count($pieces) - 1)]; // ext = bar

that's my example filename.
just wanted to show you, that your script won't work as expected with serveral dots in the filename.

Sorry pYrania, but your example is not right. The number of dots in the filename doesn't change anything in such an example. Beacuse file extension is always the last part in the filename. In your example $ext gives "txt" not "bar". The code that farawayman gave doesn't seem to be false. It should work.

Can you give a little more details pls? What happens when you try to upload a file other than txt file? Doesn't it upload? Or does it upload it with a false extension? What is the result?

Hi CaN,

The file does not upload - period.

If I try with a text file it works.

Really strange stuff.

Using php 4.3.7 and IIS

Cheers!

Try with this..

$email_user is a variable contain username
$userfile is from the form

/* File Upload in Start */
       $today = date("YmdGis");
       $pieces = explode(".", $_FILES['userfile']['name']);
       $ext  = $pieces[1];
       $filename = $email_user.$today.".".$ext;
       $uploaddir = '../uploads/';
       $uploadfile = $uploaddir . $filename ;
if (is_uploaded_file($userfile)) {
  (move_uploaded_file($userfile, $uploadfile));
}
/* end file upload */

If you do any changes in the Configuration files(php.ini,httpd.conf), then you must restart the web server to reflect the new changes.

There's a little wheel reinventing going on here - It's not like no-one has ever needed to figure out an extension before:

http://uk.php.net/manual/en/function.pathinfo.php

$p = pathinfo($_FILES['userfile']['name']);
$ext = $p['extension'];

Okay at first that did not work and then I think I discovered the problem and then my original solution should work ....

The problem was:

<INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="1000">

Remove this and it works a treat.

:-))))))))))))))))))))))))))))

Okay points time:

pYrania - 100 points for being up so early to assist.
ushastry - 200 points for being persistant
squinky - 200 points for showing me the light

Thanks all!
