mkdir upon registration

I was wondering if it would be possible to add a function to the php that would create a new directory on my server when someone registered with the same name as the person's user name?  I.E. every time someone registers on my site it would create a new directory on my server named after that person.

you mean to create a directory with the used user name?

thats possible, but you need to validate first that the user name has only valid chars.

use the mkdir function in your registration / validation process (you can do that outside the AU class)

Yes, that's exactly what I mean.  So what your saying is I can enter this function along with the char validation on the registration.php page?

yeah like:

if (submit) {
  if (valid login name) {
    create directory
....

you can do that in two parts:
1. check login name while registration
2. create directory after account is approved

Sounds good Olaf, great work on thise login system.

Hi Olaf, I had one more quick question.  On the example.php, after I have automatically generated the new directory with the user's login name, would there be a way to insert an iframe that would reference to the current logged in customer's new directory?  If so, what would I need to put in the iframe tags to do this?

why an Iframe?

Because I want to post design work in the iframe that would be in the user's directory.  Maybe I wouldn't need an iframe, maybe just a link to the .jpg file in the user's directory.  What do you think?  Is it possible?

sure why not, protect the directories and open the content from the directory with file functions
