error permission not permitted

[Najm-ul-Abideen]

Thanks,

Basically I was doing this on:

http://gifs.zxq.net

As you can see on the site I am keeping images, and I am having cautions to avoid porn or other abuse images uploaded by the users. Therefore I made a script to list down all and delete. But when I submit the page it gives me the error of "permission denied in xyz page", therefore I changed the chmod("filename",0777) then execute but now it gave me the error permission not permitted in this situation what I suppose to do.

And I also chown("filename","user") but it is giving error that unable to find uid "user" 1st I have used my username and then the ftp username but on both I got this

please help me as soon as possible as I have to complete this, its complete just this tasks remaining as during upload I am in same situation which is basic for my site.

Thanks,

Najm.

There should be no reason to chown the file, the webserver runs via mod_php and file permissions assume that of the webserver (user 'vhostswww' and group 'vhosts'). Your username is completely virtual and the user does not exist in the *nix respect.

By chmoding it to '770' the group ftp users and web server is in should have access to writing to that file. I wrote a little test script:

The ftp session (ncftp is my ftp client):

CODE

ncftp / > mkdir uploads
ncftp / > chmod 770 uploads

# drwxrwx---    2 3448     vhosts       4096 Sep 25 15:36 uploads

The creation:

CODE

<?php
touch('./uploads/test.txt');
?>

The file write:

CODE

<?php
$fp = fopen('./uploads/test.txt', 'w');

if($fp !== false)
{
   fwrite($fp, 'Some content');
   fclose($fp);

   echo 'Content written.';
}
else
{
   echo 'Error. Can not open file pointer.';
}
?>

This went without a hitch, the contents of that file being 'Some content'.

Directory listing was also fine:

CODE

$dir = opendir('./uploads');

while($file = readdir($dir))
{
   if($file == '.' || $file != '..')
      continue;

   echo $file, "\n";
}

So there is no need to chown or chmod inside of your script, providing the directory / file has sufficient permissions it will write to it, and you'll be able to list the contents.
