if folder exists...

I'm trying to create a global that will check to see if a folder, named the same as a user's login name, exists under /www/html/files/{user_name}. It then needs to return a link if it does, and a different link if it doesn't. So basically it would be:

<%my_global(user_name)%>

Then, the global would take the current user name passed to it, and check to see if the folder exists. It would then return the appropriate href line.

I hope I made some sort of sense with this. Any help would be greatly appreciated. I'm not that great of a programmer. Unsure

Try this;

1) Make a new global; call it "check_folder_exists", and put the following code in;

Code:
sub { 

  my $folder = '/full/path/to/folder'; 
  my $user   = $_[0]; 

  if (-e "$folder/$user") { 
    return { folder_exists_user => 1 }; 
  } else { 
    return { folder_exists_user => 0 };   
  } 
}

2) Then open the template, and put;

Code:
<%check_folder_exists($Username)%>

... which will then set <%folder_exists_user%> to either 1 or 0, depending if the folder exists.

3) You can check this with;

Code:
<%if folder_exists_user %> 
... folder exists 
<%else%> 
  do something else 
<%endif%>

This is untested, and $Username may need to be replace for the specific user. However, the format should be ok Smile

Wow, thanks, Andy! If I pass the username from the template, is that the correct syntax? I'm not sure if the following will work:

<%check_folder_exists(current_user_username)%>

The tag for the current user is:
<%current_user_username%>

Thanks,
Sean

No worries. In that case, you need to use;

<%check_folder_exists($current_user_username)%>

Note the additional $, which is required to pass tags into globals.

Should work though :)
