File Upload

[Spudster]

Hi,

The question I have is regarding php file upload.  What i need is a way to check and see if a filename is taken before it is uploaded.  PHP does this on its own, but you get some generic php fatal error.  I want to make it so I can make something comes up, just like a warning that the filename is taken.  Here is the script for that part:

<?php

  if ($_FILES['userfile']['error'] > 0)
  {
    echo 'Problem: ';
    switch ($_FILES['userfile']['error'])
    {
      case 1:  echo 'File exceeded upload_max_filesize';  break;
      case 2:  echo 'File exceeded max_file_size';  break;
      case 3:  echo 'File only partially uploaded';  break;
      case 4:  echo 'No file uploaded';  break;
    }
    exit;
  }

  // Does the file have the right MIME type?
  if ($_FILES['userfile']['type'] != 'text/plain')
  if ($_FILES['userfile']['type'] != 'video/quicktime')
  {
    echo 'Problem: file is not a text document/Quicktime video';
    exit;
  }

  // put the file where we'd like it
  $upfile = '/uploads/'.$_FILES['userfile']['name'];

  if (is_uploaded_file($_FILES['userfile']['tmp_name']))
  {
    if (!move_uploaded_file($_FILES['userfile']['tmp_name'], $upfile))
    {
        echo 'Problem: Could not move file to destination directory';
        exit;
    }
  }
  else
  {
    echo 'Problem: Possible file upload attack. Filename: ';
    echo $_FILES['userfile']['name'];
    exit;
  }
  echo 'File uploaded successfully<br><br>';
?>


Any help would be great.  Thanks

[quote]PHP does this on its own, but you get some generic php fatal error.[/quote]
which line of code gives the error.?

TIP..
put the @ symbol in front of the offending function call to suppress that fatal 'generic' error

example
[code=php:0]
$moveFile = @!move_uploaded_file($thisfile, $here);
if(!$moveFile)
  show error
[/code]

I dont even know, lol which is pretty pathetic, but im assuming its the last else statement...i think

[Zane]

well .... it should tell you the line number in the Fatal error

make it do the error again
and post it here along with where the line is

now i am not getting anything.  it says it wrote to the database and uploaded the file to the correct place, but nothing new is added to the db and the file is still in the folder

[Zane]

not sure if it has anything to do with it...but I would think so

you can get rid of all those exit functions.
They stop you're script
