Unable to open folder/file

Postby llsastre » 10. November 2008 11:40

I'm trying this script http://www.buayacorp.com/archivos/guard ... -de-mysql/ and I need to have 777 permissions on a folder, but I'm unable to get it.
I'm working with windows vista and XP. I make a new folder (for example D:\tmp) and click with right button and then, in security tab, aply a total control to all users, but this script always tells the same error message: "Unable to open D:/Temp: Permission denied ..."
What must I do to change permissions?
Thanks.

Permissions 777 is for a 'nix OS not for Windows.

You could try creating the Temp folder in the same folder as your script in the .\xampp\htdocs\ folder as without setting the correct permissions for a folder outside the htdocs (the DocumenRoot) in the httpd.conf file then your script won't be able to write to it.

No write permissions

I've tried it as you say but doesn't work either. It says "Unable to open 'tmp/' for writing: No such file or directory in C:\xampp\htdocs\web\grava_compr.php on line 87"
This folder 'tmp' is in 'web' folder and I've applied write permissions to all, but it doens't work.
I don't know what more can I do.

Paste here the relevant part of the script you have changed.

You can try this:
Create your temp folder in
C:\xampp\htdocs\web
So the path is:
C:\xampp\htdocs\web\temp

In your script where it asks for the path to the Temp folder type the above path like this:
"C:/xampp/htdocs/web/temp/thumbtemp"



I have had a look at the script you are trying to install and perhaps the relevant part you have to change looks like this:
Code: Select all
# Nombre del archivo temporal del thumbnail
define("NAMETHUMB", "/tmp/thumbtemp"); //Esto en servidores Linux, en Windows podría ser:
// define("NAMETHUMB", "c:/windows/temp/thumbtemp"); y te olvidas de los problemas de permisos

The comments roughly translated:
Code: Select all
# Name of the temporary file of the thumbnail
define("NAMETHUMB","/tmp/thumbtemp"); //This for Linux servers, in Windows it could be:

// define("NAMETHUMB","c:/windows/temp/thumbtemp"); You forget the problems of permissions

So if you create the temp folder in the above suggested path then this is what the NAMETHUMB entry could look like.
Code: Select all
define("NAMETHUMB","C:/xampp/htdocs/web/temp/thumbtemp");

...and as the comment tells you "Forget changing the permissions to (777) on Windows". The permissions required are usually already in place.

I know 777 permissions is only for unix/linux OS. I've writed so only to say that I need write permissions on this folder. In windows XP and vista must change the properties-security folder permissions for every user on it.
I've tried all your advices, but they don't work. Finally, with a bit of luck, I've tried this (Previously I've changed permission to total control to all users to this folder "C:/xampp/tmp/"):
...
$urltmp="C:/xampp/tmp/";
switch($type) {
case $mimetypes[0]:
case $mimetypes[1]:
$img = imagecreatefromjpeg($tmp_name);
$urltmp=$urltmp."imatge.jpg";
break;
case $mimetypes[2]:
$img = imagecreatefromgif($tmp_name);
$urltmp=$urltmp."imatge.gif";
break;
case $mimetypes[3]:
$img = imagecreatefrompng($tmp_name);
$urltmp=$urltmp."imatge.png";
break;
}
define("NAMETHUMB", $urltmp); //y te olvidas de los problemas de permisos
...
and now it works fine.
I think I had given permissions correctly to the folder, but the original script doesn't find the file to read/write on it. Now, I add a name to this image file "imatge.xxx" and it can read/write/erase the file.
It's a little bit strange because on a linux server the original script works fine as is.

Thanks a lot for your help. It has helped me to think with other possible (or impossible) solutions.

I hope this helps those that have been struggling with this for a while.

Why can't windows just use the simple Unix style permission system rather than all this bs.
