#9333 — mkdir no such file or directory

I want to create a directory using mkdir. But I get "No such file or directory" error.

Below is the code I am using.

$filelocation = "/uploads/" . "/" .  time();

Can some one please tell me what I am doing wrong?

I also tried manually creating the uploads folder. Still the same error. Any help will be much appreciated.

#9334

Here is my code again

$filelocation = "/uploads/" . "/" .  time(); 
if (mkdir($filelocation,0777,true))
{
    echo("Thank you for uploading the file.");
}
else
{
    echo("Oops error uploading file.");
}

mkdir() will only give true or false depending on if it can create the 
directory or not.

Usually the user as who the process is run as (web server user or a 
normal user) will not have the right to make a directory in the root 
file system (path: /), but we assume you have full control of the web 
server and can create the directory /uploads and have already made it, 
then you need to allow the web server/normal user as whom the php script 
is run as to have rwx on that directory.

$path = "/uploads";
$dir = time();

if(file_exists($path)) {
	if(file_exists($path."/".$dir)) {
		echo "directory {$path}/{$dir} already exists";
	} else {
		if(mkdir($path."/".$dir,0777,true)) {
			echo "Created {$path}/{$dir}";
		} else {
			echo "Can't create {$path}/{$dir}";
		}
	}
} else {
	echo "{$path} is missing";
}

This is a simple check with a bad way of echoing out results, this don't 
check if the file really is a directory, is_dir() will tell you that if 
you want to make the check more complete, I suggest you look at 
Exceptions instead of just echo everything.

I don't know anuything about mkdir, but isn't:

"/uploads/" . "/" .  time()  the same as: 

"/uploads//".time();

Are those two forward slashes causing the error?

When I modified your error line to:
     echo("Oops, error creating directory \"$filelocation\".");

I got the output:
     Oops, error creating directory "/uploads//1368592056".

Note the double "/" in the directory name.

Also, check you have permission to create a
directory in your root directory.

1) Look carefully: "/uploads/" . "/" will result in "uploads//"

2) Does /uploads exist? It seems you miss the whole path the the root
directory of the webserver (/var/www/....) or you did not understand the
difference between the root URL in your browser and the physical path on
the machine where the script runs.

I assume you need a full path and not just "/uploads" and you have to
make sure, that the user which is used to execute PHP has the right
access rights within the given path.

that looks to me like "/uploads//12345678901234567890"

which probably isn't a reason for failure with the double slash, but is 
ugly.

However, do you have permission to create a directory in the root file 
system of your computer?

Try removing the leading slash to its relative to wherever PHP is 
operating, or better still use the PHP defined constant that tells you 
where the root file system is, as a prefix.

Does /uploads exist on your system?
If /uploads does exist, has the webserver process got sufficient access 
to create subdirs in it?
If /uploads does not exist, has the webserver process got sufficient 
access to create it?

Given that creating anything at / usually requires root level access, and 
it's generally not recommended to run web servers as root, I suspect 
access rights might be your problem.

And: maybe the OP *really* means something like:

$filelocation = dirname(__FILE__) . "/uploads/" . "/" .  time();

That is, he might really want uploads to be *relative* to files on the 
website, rather than a absolute place on the server's file system. (The 
'dirname(__FILE__)' is just an example, there might be other possibilities.)

Hi Robert,

I want the uploads directory where I am hosting the website files.

[toc] | [prev] | [next] | [standalone]

#9355

ie, if my website is called example, the structure will be

example
  index.php
  upload.php
  search.php
  uploads
    12209214
       somefile.txt
    31231203
       otherfile.txt
  about.php
  contact.php

Please learn how to post properly on Usenet.  Avoid Google Groups in favor 
of a locally installed newsreader application if possible.

The problem here is that you are falsely assuming that “/” refers to the 
document root.  Instead, it refers to the *filesystem* root, where you/the 
Web server SHOULD NOT have write access.  As “uploads” is a directory on the 
same level as upload.php, it is probably easiest for you just to omit the 
leading “/”.  

However, it would be safest to refer to the document root explicitly, like

  $_SERVER['DOCUMENT_ROOT'] . '/uploads/' . $value

(As you can see, it does not make sense to concatenate '/uploads' . '/' when 
you can just write '/uploads/'.)

It also does not make a lot of sense to create a directory for every second 
of upload since epoch, using time().  If you need to group uploads by date 
for quick access, I suggest you use year/month/date instead.  That said, you 
can rather easily filter an array of file information, so unless there is a 
chance that on different times people would upload files with the *same* 
name where they do *not* want to overwrite the old version, you do not need 
that directory structure.

However, in a multi-user application another piece is missing in any case: 
You need a way to differentiate between the files of users or one user could 
overwrite the file of another.  Using time() _cannot_ prevent that from 
happening, because there is the possibility of concurrent access.

Thomas,

Thanks for your feedback.

I just put that uploads/time format as an example. In the real application I will be using

uploads/<username>/time format

Please learn how to post properly? Don't really know what you mean. Thanks a lot anyway for your help. Appreciate it.

Thank you
Bhushan

That means you don't want "/uploads"!  If the mkdir code is in upload.php, 
then you really do want:

    $directory = dirname(__FILE__) . "/uploads/" . time();

From PHP 5.3 on they may want to use

     $directory = __DIR__ . "/uploads/" . time();

instead.  However, see my other answer as to why either approach is not a 
good idea.
