mkdir issue

[timlondon]

The following successfully creates a directory for $path but fails to make a directory for $path2 (without redirecting to fatalerror.php). Anyone know why?

 

$path = "members/".$fl."/".$name;

$path2 = "members/".$fl."/".$name."/priv";

mkdir($path, 0755);

chmod($path, 0777);

if(is_dir($path)) {

mkdir($path2, 0755);

chmod($path2, 0777);

} else {

header ("Location: fatalerror.php");

exit;

}

You say it successfully creates the directory, but PHP obviously doesn't think it does- are you seeing the directory when you ftp.

 

Is PHP in safe mode?

(run phpinfo() and check the safe_mode setting)

[timlondon]

$path is successfully created. I can see it if I FTP it. But it won't create the subdirectory. 

[timlondon]

For safemode master value is off but local value is on. Not sure what that means???

[mrjcfreak]

local value = on,  I assume, means that your server has PHP safe mode enabled.

 

PHP has a so-called 'Safe-mode' where almost all of it's functionality is crippled. Crucially, you can't make changes inside folders which you make with a script. It's down to permissions and folders you make with PHP having a different group ID making them unusable.

 

It sounds like you're on shared or hosting, and you can't change this setting, in which case there is little you can do except change tactics. Instead of using new directories use funky filenames:

 

so instead of making "bob" inside users/private, make a file called

users-DR-private-DR-bob... making sure to use separators that wont be in your "filenames"

[timlondon]

I'm on hosting but i can change the ini file. Is it simply a case of switching safemode off??

[mrjcfreak]

Yep.

The manual has a fair bit to say about it all:

http://uk.php.net/features.safe-mode

[timlondon]

Safe modes off (it was off all along) so that's not the problem.

 

Any ideas anyone??

Looking at your code you say it is hitting the redirect, which means it is not a problem with creating the folder, since the if statement stops it from ever hitting that portion of the code.  The problem must be with is_dir, which I have had problems getting to work before.  Maybe try using the full path to the folder including /home/user/...etc.  Or try removing the if is_dir clause around the directory functions and see if it works that way.

[l4nc3r]

Try using an if statement in there, like so:

 

$path = "members/".$fl."/".$name;
$path2 = "members/".$fl."/".$name."/priv";
mkdir($path, 0755);
chmod($path, 0777);
if(mkdir($path2, 0755)) {
  chmod($path2, 0777);
} else {
  header ("Location: fatalerror.php");
}
exit;
}

[timlondon]

l4nc3r, just tried that.

 

The problems still there.

 

The $path directory is created but the $path2 (a sub folder of $path) isn't. It doesn't redirect to the error page.

Your mask could be removing permissions. I would see if chmod is working properly, and if not, try removing your mask with umask.

The chmod seems to work fine. The $path folder which is successfully created is also successfully modded to 0777.

[timlondon]

I've just noticed that the ownership of the $path directory is user - apache and group - apache. Is this an ownership problem?????

[effigy]

What does this tell you about the directory and subdirectory?

 

<pre>
<?php
print_r(stat('directory_name'));
clearstatcache();
?>
</pre>

<pre>
<?php
print_r(stat('directory_name'));
clearstatcache();

</pre>

 

It tells me:

 

Array ( [0] => 2053 [1] => 13207891 [2] => 16895 [3] => 2 [4] => 48 [5] => 48 [6] => -1 [7] => 4096 [8] => 1185988020 [9] => 1185988020 [10] => 1185988020 [11] => -1 [12] => -1 [dev] => 2053 [ino] => 13207891 [mode] => 16895 [nlink] => 2 [uid] => 48 [gid] => 48 [rdev] => -1 => 4096 [atime] => 1185988020 [mtime] => 1185988020 [ctime] => 1185988020 [blksize] => -1 [blocks] => -1 )

Actually, let's try this to get more information (and recursively). Pass it the full path of what you want to check.

 

<pre>
<?php

function analyze($path) {
	$dirs = explode('/', $path);
	foreach ($dirs as $dir) {
		if ($prev_dir) {
			$dir = $prev_dir . '/' . $dir;
		}
		$stat = stat($dir) or die;
		$perms = substr(sprintf('%o', fileperms($dir)), -4);
		$grp_info = posix_getgrgid($stat['gid']);
		$grp = $grp_info['name'];
		$usr_info = posix_getpwuid($stat['uid']);
		$usr = $usr_info['name'];
		echo "<b>path:</b> $dir<br>";
		echo "<b>perms:</b> $perms<br>";
		echo "<b>user/group:</b> $usr/$grp<br><br>";
		clearstatcache();
		$prev_dir = $dir;
	}
}

analyze('path/to/my/subdir');

?>
</pre>

Sorry effigy, I was delayed dealing with this problem.

 

I've ran the above and got the following:

 

path: members

perms: 0777

user/group: harlow/apache

 

path: members/c

perms: 0775

user/group: harlow/apache

 

path: members/c/chukleslondon

perms: 0777

user/group: apache/apache

 

I'm assuming that my problem is with the user apache???

 

If so am I correct in thinking that this is something that my host can resolve???

 

Am I also correct in the assumption that theoretically I can use mkdir to create a folder and then use mkdir to create a subfolder within that folder????

 

My host is being very unhelpful so I think I need to go back to them armed with some facts.

 

Your help is much appreciated.

 

[effigy]

Which one of these gives you trouble with mkdir? Everything looks OK to me since they're all in the apache group.

[timlondon]

The problems with chukleslondon.

 

That folder was created by mkdir and chmodded to 777.

 

The script then tries to create a subfolder within chuckleslondon but it simply wont do it.

[effigy]

What user/group is the server running as? apache/apache?

 

The permissions for "chuckleslondon" is 777, which means any one can do anything, such as creating a directory.

 

Have you tried mkdir's recursive argument?

 

Does a terminal/FTP login show you the same user, group, and permission information?

 

Also, going back to mrjcfreak's comment about safe mode, is everything off, including the local = on?
