For a project I'm implementing a file-upload system. For every user account I would like the script to create a different sub-folder. Lets say their user_id's.
Each time a user is added, the system will create a new sub-folder for their own uploads. For example:
Uploads/
- user1
- user2
- user3
By executing mkdir('Uploads/'.$user_id, 0777); it will create a new subfolder. Everything is fine.
However my application is not able to write to this folder. How do I have php make directories with the required file permissions? I have tried using chmod with no success.
This might help chmod and mkdir
$dirMode = 0777;
mkdir($directory, $dirMode, true);
// chmod the directory since it doesn't seem to work on recursive paths
chmod($directory, $dirMode);
For mkdir, mode is ignored on Windows. and 0777 is by default. and the third param is recursive which allows the creation of nested directories specified in the pathname.
sometimes the directory created with another mode than specified ( 0755 instead 0777 etc).
to solve that use :
<?php
$old = umask(0);
mkdir($dir,0777);
umask($old);
?>

I'm trying to recursively create a directory using php's mkdir function in a Codeigniter installation. My code looks like this:
mkdir('docs/client/bills/payd', 0777, true)
The docs directory already exists in my site root dir, the client directory is beeing created with 0755 permission, the bills directory is beeing created with permission 1341 (weird!) and the last directory, payd, is never created.
I tryed to change permission in the mkdir argument list to 0, 755, etc... and nothing has changed. I also tryed to set umask to 0, 0777... and nothing.
umask(0777);
mkdir('docs/client/bills/payd', 0777, true)
Can anyone please say what am I doing wrong? The code above is called from a Codeigniter regular controller.
Try with
if ( ! is_dir( FCPATH.'docs/client/bills/payd' )//FCPATH is absolute path to the project directory
{
mkdir( FCPATH.'docs/client/bills/payd', 0777, true );//although 0755 is just fine and recomended for uploading and reading
}
Use this to specify it the working directory, it might be confused as to where the directory is located.
mkdir( getcwd().'docs/client/bills/payd', 0777, true);
getcwd is the working directory for your codeigniter. You can search in the PHP guide the getcwd() function to make it clearer.
This should work.
EDIT
To make it clearer, that would return the following:
C:\xampp\htdocs\YOUR_ROOT_DIRECTORY\docs\client\bills\payd
EDIT AGAIN
Although after reading again, this would only create payd and assume that docs\client\bills is already created. You could create client and bills using mkdir or using the file explorer. But there are other PHP ways and I can help if needed.
Goodluck meyt
I also had this weird "1341" permissions error with PHP mkdir, nothing to do with CodeIgniter, it's a pure PHP issue!
After much experimentation, the only way I could get it to work was to include a slash at the end of the path, and set the recursive flag to 'true'. (Even though the PHP docs don't show a final slash, and I was only creating a single directory.)
I.e.
$existing_path = '/these/directories/already/exist/';
mkdir( $existing_path . 'new-directory/', 0755, true);
I have a php script that is used to create different directories for different users to store their images.
One way to do this is use 777 permision like this:
$path = 'images/product/'.$pid;
if( ! file_exists($path)) {
$mask=umask(0);
mkdir($path, 0777);
umask($mask);
}
Is there any other alternative that doesn't involve to use 777 permision for the directory, for example to set the file owner and group?
Changing the file owner/group requires privileges that your Apache should not have if you want to run it safely.
However, you don't necessarily need 0777. I guess you are storing images, so you can use 0644!
Side note: chgrp() and chown() are the 2 functions giving you the ability to change file group/owner
I have read this:-
Why can't PHP create a directory with 777 permissions?
and I can see a new folder being created by applying the following:-
// Desired folder structure
$structure = "../../../".$flash_dir."HELLO";
// To create the nested structure, the $recursive parameter
// to mkdir() must be specified.
$oldmask = umask(0);
mkdir($structure, 0777);
umask($oldmask);
when viewing the file permission of HELLO with DreamWeaver, it is 777. However, I suspect it is a Linux 0777 rather than a Windows 777, therefore I still cannot upload things to HELLO.
Will there be any alternative method to create a directory with windows 777? Thanks!
PS. when I manual create a new directory and right click it to set 777, it works perfectly, so I really think it's related to Linux vs Windows~
0777 is exactly the same thing as 777
But I still can't say what the problem is. I would try to chmod it again after you've created it.
$oldmask = umask(0);
chmod($structure, 0777);
umask($oldmask);
I have my web application hosted in /var/www folder. I am creating a folder from one of the PHP scripts of the web application. The default permission of the created folder is drwx------, i.e. 700. But I want that folder to have at least 755 permission.
Up to now I tried: mkdir($path, 0755) and chmod($path, 0755) PHP functions but without any success.
Does anybody know how to solve my problem please?
Millions of thanks beforehand.
Have you tried changing the umask ?
Have a look here: http://nl3.php.net/manual/en/function.umask.php
The easiest way it to:
$oldmask = umask(0);
chmod($path, 0755);
umask($oldmask)
Since you have default permission of 700, which means the parent directory (the directory in which you are trying to create the folder) do not have rw permission for group owner or other users. Most often the running demon(httpd) is not the owner of the parent folder and hence cannot modify the directory.
In simple terms, the php script do not have access to modify or add new directory. You need to change the permission of the parent folder to at least drwxrw-rw- (or 0755).
Use ssh, cpanel or ftp client to do this. If you do it using php script you will end with the same problem again, as parent of parent will have again 0700. ;)
i was using this basic script:
$folderPath = "../path/to/$folder/";
mkdir("$folderPath");
i create this directory and then upload photos to it. I've been doing this for a good 4-5 months now and suddenly i start getting 'FORBIDDEN' errors when I attempt to view the contents of the folder via web browser
The directory is being created the same and the photos are still uploading without a problem, but I cannot access the photos
I tried rewriting the script and using chmod to change the permissions but I'm having no luck at all
All the older folders were being created with: -w- rwx r-x r-x
and I can't get this recreated
I've tried adding a chmod line into my script:
$folderPath = "../sales/inventory/$folder/";
mkdir("$folderPath");
chmod("$folderPath", 0755);
but I can't recreate the same permissions, I'm trying to understand how chmod works, but I can't figure out how to get this very basic function working properly again
Try looking out for a HTAccess file, where the "Options -Indexes" option will be mentioned, as this is mostly used for not showing the contents of a folder in a web browser. The file needs to be searched in the following manner:-
In the folder "root_folder/sales/inventory/$folder/", where "$folder" is as mentioned in your code.
If not found, try in the folder "root_folder/sales/inventory/".
If not found, try in the folder "root_folder/sales/".
If not found, try in the folder "root_folder/".
When you get the code of "Options -Indexes" written in the HTAccess file, you can remove / comment that line of code from there, or you can also write another HTAccess file in your required folder of "$folder", where the code will be "Options Indexes".
Also in the PHP page, the logic must be like this:-
<?php
$folderPath = "../sales/inventory/$folder/";
mkdir("$folderPath");
chmod("$folderPath", 0755);
// Use of "copy()" / "move_uploaded_file()" function here, using some "$targetFile" variable.
chmod($targetFile, 0755);
?>
This will help you when you will be unlinking / deleting the uploaded files from the "$folder" folder.
Hope it helps.
If your $folder variable includes some sub-directories your parent directories are maybe not being chmoded to the right permissions. This was the problem I was having on a hired OVH Gentoo server.
Imagine that $folder = '/store1/ally23/shelf42'; so your final directory structure is
../sales/inventory/store1/ally23/shelf42, and you want 0777 permisions.
You do:
mkdir($folderPath, 0777, true) || chmod($folderPath, 0777);
Only the final directory shelf42 is chmoded to 0777. The intermediary directories are created with default permissions (in my case 0744).
There is no recursive option in PHP's chmod command, so you have to loop over the intermediary directories and chmod them individually.
If you're in a shared environment, you may also want to chown after upload, to be on the safe side. Especially if you're running your web server under a user other than your virtual host has permission to access (EG: "nobody" vs "mysite".) This is common with cPanel servers, FWIW.
Simply umask means the default permissions for new files/directories:
<?php
umask(022);
?>
This sets the default permissions for user, groups, and others respectively:
0 - read, write and execute
1 - read and write
2 - read and execute
3 - read only
4 - write and execute
5 - write only
6 - execute only
7 - no permissions
