chmod operation not permitted

[nozom]

i want to change the CHMOD of a dir from 0755 to 0777 and back again after my image is uploaded using this code

chmod ($dirpath, 0777);

and i'm getting this error:
chmod failed: Operation not permitted

Is this because the version of php i'm running doesn't support this, or is it because i'm trying to ochmod a whole dir, or is it because i'm crap ;-)

Cheers,
Hugh

It's because you're crap--no, no, you just need permissions to chmod, and evidently you don't have them. 🙂
If you're on a local computer, change the access from (probably) the user "nobody" to something with less restrictions, and all should be fine. If you don't use a local computer, ask your server if you can have access to chmod things.
