[Resolved] Automatic CHMOD?

[bpat1434]

hey guys. I'm working on a script that would allow users to upload files to a directory. What I want is to have users be able to choose the following items:

Year of the photo,
Category of the photo,
Event photo was taken at

Now, I need to create a folder that will store these photos.

$updir = $_SERVER['DOCUMENT_ROOT'].'/images/photos/'.$year.$cat.$evt;

To check to see if the folder exists:

fopen($updir, 'w+');
/* From what I understand, w+ will look for the folder, and if it is not present, create it.*/
CHMOD($updir, 755);
/* Change the permissions to 755 so that people can write to it. */
fclose($updir);

Now, here's my question. I need to chmod the folder $updir, is what I have correct? And is my fopen() function proper? THis is just a check. I haven't tested yet as I'm in the very early stages. Thanks for the help.

EDIT
Would I even need to make it writable? If all uploads go to a temp directory by default, and I'm moving the file from there to the $updir, would I need to CHMOD it? So I guess the real question is: Do I need to do CHMOD() and if not, is that fopen the best way to check to see if the directory is there and if not create it?

Why not just create a directory when you create a category.

$catName = "Testing Category";
$directoryName = str_replace(" ","_",$catName);
mkdir($directoryName,0777);

Then when you call the directory, you just do the same thing.

$directory = str_replace(" ","_",$row["catName"]);
echo "<a href=\"$directory/".$row["imageName"]."\">".$row["imageName"]."</a>\n";

I would love to just do that, but what I need is to automatically create a directory so that I don't have to manually do it.

Here's what's happening:

--User inputs data into form
--Form is submitted to PHP script
--PHP Script grabs info and puts it into variables
--A function is called "check_dir()" where I want to see if there is already a directory named $cat there ($cat being the category name).
-- -- If not, then create the directory
-- -- If so, then move to next step
--Check to see if there is already a directory named $evt ($evt being the event name).
-- -- If not, then create it.
-- -- If so, then next step
-- Run the rest of the script

So you see, I can't just make the directory, I need to see if it exists first. I figured that I would be able to do it with fopen($updir, "w+"), but that doesn't work.

Now that I think about it, perhaps I could do this:

<?php

function check_dir(){
    if(!is_dir($dir.$cat)){
        mkdir($dir.$cat);
    }
    if(!is_dir($dir.$cat.$evt)){
        mkdir($dir.$cat.$evt);
    }
    doRest();
}

I'll check that out later. If anyone else knows of any better way to check to see if a directory exists, and if not then create it, please let me know.

Actually, you could just
@mkdir($dir.$cat);

If you know you want it to be there, just issue the command to make it. If it's already there, the command fails, but no harm is done. If it's not there, the command succeeds.

Thanks!! Just what I was lookin for.
