Update file permissions

billhobbs

I'm using an upload script to upload images into a directory. The permissions on the directory are set to 777. When I upload images the files permissions are set to 644. This is a problem because I'm using a script to delete the files if they are orphaned from the database. But my script won't delete a file with 644 permissions. Is there a script that I can use to update all the files in the directory to change the permissions to 755?

[man]chmod/man

EDIT: You might instead be able to use [man]umaskman to change the permissions that PHP will give the new files before they are created.

I tried this script but kept getting errors:

$path="userphotos";
$dh = opendir($path);
while ($temp = readdir($dh)) {
if ($temp!='.' && $temp!='..' &&
$temp!='.htaccess') chmod($temp,755); }

I've also tried:

$cm = chmod($curDir,0755)

I just keep getting errors.

For one, 755 is not the same is 0755.

For another, what are the errors you're getting? Hard for us to help you diagnose them if we don't even know what they are.

Let's start with the first one. I you have a cleaner script I'm open I just need something that works.

$path="userphotos";
$dh = opendir($path);
while ($temp = readdir($dh)) {
if ($temp!='.' && $temp!='..' &&
$temp!='.htaccess') chmod($temp,0755); }

Gave me this error:

Warning: chmod() [function.chmod]: No such file or directory in /home/content/w/d/h/wdhobbs/html/folder/updatepermissions.php on line 6

I have the script outside of the userphotos directory and the directory permissions are set to 755 I also have a .htaccess file that I'm using to rewrite the url to a www. and change the .php to .html.

So the folder that you're trying to access is located at /home/content/w/d/h/wdhobbs/html/folder/userphotos/ ?

billhobbs

folder replaces the name for security purposes in the path. The userphotos is the directory that has the images I want to change the permissions on. The php script is located in the folder directory.

Right, and what I'm asking is if that is where the 'userphotos' directory is as well. In other words, assuming 'folder' is whatever directory name you actually gave it, is my example absolute path to the 'userphotos' directory correct? If it isn't, then you need to supply PHP with the correct path.

billhobbs

folder is the directory where the index file is. The userphotos directory and the updatepermissions.php file are in the folder directory.

If you can successfully get a directory handle for "userphotos", you are currently in the directory containing userphoto - you are not in the userphoto directory.

However, what does this tell you?

if ($temp != '.' && $temp != '..' && $temp != '.htaccess')
{
	echo 'chmodding: ' . $temp . PHP_EOL;
#	chmod($temp,0755);
}

I didn't get an error but the message was chmodding:

None of the files were changed in the userphotos directory

Did you not change that part of the original code but just went along and used the code I posted as completely standalone?

That is, the script you should execute should obviously look like this

$path="userphotos";
$dh = opendir($path);
while ($temp = readdir($dh))
{
	if ($temp != '.' && $temp != '..' && $temp != '.htaccess')
	{
		echo 'chmodding: ' . $temp . PHP_EOL;
	#    chmod($temp,0755);
	}
}

That should definitely NOT produce the output you posted, at least not unless you have a file named as an empty string. That's why I'm guessing that you didn't try more than the exact code snippet I posted rather than use it with the stuff it needs to work like it should, which on the other hand WOULD produce an error message for $temp being undefined.

No, of course not. That part is commented out since it (presently) only produces errors anyway.

billhobbs

The code found the two files and listed them.

I deleted the commenting and tried using the code and the error message produced was:

chmodding: NoPhoto.jpg
Warning: chmod() [function.chmod]: No such file or directory in /home/content/w/d/h/wdhobbs/html/FOLDER/updatepermissions.php on line 9
chmodding: 1HEJ4Pic.jpg
Warning: chmod() [function.chmod]: No such file or directory in /home/content/w/d/h/wdhobbs/html/FOLDER/updatepermissions.php on line 9

bradgrafelman

You need to give [man]chmod/man the path to the file - not just the file name.

billhobbs

Do you mean like so:

$path="userphotos"; 
$dh = opendir($path); 
while ($temp = readdir($dh)) 
{ 
    if ($temp != '.' && $temp != '..' && $temp != '.htaccess') 
    { 
        echo 'chmodding: ' . $temp . PHP_EOL; 
chmod("$path/$temp", 0755); } 
    }

This appeared to work.
