imce - spaces in user names

If the directory name is "user name" then the URL should contain %20 instead of the space. This is the intended behavior. An URL should not contain spaces.
However, if you want to change the behavior, you can have a look at getURL method in imce.js file. You can add path.replace(/%20/g, ' ') to convert them back.

No it wont work because the URL becomes incorrect. And also there could be two users with the names "user name" and "user-name". You need to differentiate them.
There seems to be no solution on IMCE side. Did you search for a module that allow extra restrictions on usernames?

I did a simple username validate hack to restrict space (multiple spaces in a row are already restricted.) in usernames.

Go to user.module file and find user_validate_name and replace
if (strpos($name, ' ') !== FALSE) return t('The username cannot contain multiple spaces in a row.');
with
if (strpos($name, ' ') !== FALSE) return t('The username cannot contain spaces.');

(line # 384 in drupal 6.10)

Now, it will pose an error if anyone try to register a username containing space.

Hope this will resolve your problem.

Another approach depending on token on pathauto, is using php code in a IMCE profile:

php: return 'users/'.pathauto_cleanstring(token_replace('[user]', 'user', $user));

but build in filter to prevent '-' or ' ' to be used in usernames, whichever you prefer.

This PHP approach is perfect. Except it doesn't work for me.

When I try to navigate to the IMCE interface I get this error:

Fatal error: Call to undefined function pathauto_cleanstring() in ...\sites\all\modules\imce\inc\page.inc(724) : eval()'d code on line 1
(The ellipses are mine.)

However, if I throw this code into the page.tpl.php file in this format:

print 'users/'.pathauto_cleanstring(token_replace('[user]', 'user', $user));

it prints the correct string. So, does this mean that IMCE is trying to resolve the user name before the pathauto_cleanstring function is declared?

(Sorry if my programming terminology is wrong.)

Because this function is in a separate inc file (pathauto.inc). I think you need to include this file first. May use this function: _pathauto_include();

Fantastic! That does it. Thank you so much. Here's what I ended up using in the IMCE Directory Path field:

php: _pathauto_include(); return 'users/'.pathauto_cleanstring(token_replace('[user]', 'user', $user));

Between this tip and the Pathauto patch for enabling the lowercase setting in Pathauto to apply to the pathauto_cleanstring function, I have exactly what I need: clean, lowercase, user-based folder names. Beautiful!

For anyone searching on this topic, in D7 I was able to convert user names to lower case and replaces spaces with a '-' by entering:

php: return strtolower('users/'.str_replace(' ','-',$user->name));

Thanks a lot Slovak! That was the exact thing I was looking for!
The only thing i needed to change is to use 'print' instead of 'return'.
Somehow 'return' didn't work out.

Thanks again!
