Displaying Sub Directories

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks!
Anyone would know if its possible here in this code to display the sub directories only after been clinked on?
I am stuck, I can't figure it out even how to check if the link been displayed is a directory or a file, but my goal here is to display all the directories and if clicked, collapse with the files inside. Would be nice to test if directory path have 5 levels deep

#!/perl/bin/perl -w

use strict;
use CGI qw(:header);
use CGI::Carp qw(fatalsToBrowser);
use CGI qw/:standard/;


my $show = param("show");


my $input_dir = "/cgi-bin/cars";

print header();
print "<html>
            <head><title>Tree</title>
           
            </head>";
MAIN:
{
   my @tree;
   dirwalk ($input_dir,\@tree);
   printtree(\@tree);
   print "</OL>\n";

}

sub dirwalk
{
   my ($dir,$tree) = @_ ;

   push @{$tree},($dir =~ m#([^/]+$)#);

   opendir DIR, $dir || die "Couldnt open $dir - $!\n";
   my @entries = grep !/^\.{1,2}$/, readdir(DIR);
   closedir (DIR);

    foreach my $item (@entries)
      {
        my $fullpath = "$dir/$item";

        if ( -d $fullpath )
          {
            dirwalk ( $fullpath,\@{$tree->[@{$tree}]});
          }
        else
          {
            push @{$tree},$item;
          }
      }

}

sub printtree
{
  my $tree = shift;  
  my $c=-1;
  print "<LI><a href=\"tree.pl?show=true\"><img src=dir.gif border=0>&
+nbsp;",shift @{$tree},"</a>/53<br>\n";
  print "qqq<OL>\n";
   
  foreach my $item ( @{$tree} )
   {
    #print "<b>$item</b>";
    $c++;
     if (ref $item eq "ARRAY" )
       {

        printtree($item);
        
       }
     else
       {
         print "<LI><input type=checkbox> \n";
         print $item,"^$c-64\n";
       }
   }
  
  print "</OL>";

If you had read my original post on CLPM which had that code you would have seen that I recommended File::Find to do this. /J\	[reply]

If you are trying to display a dynamic directory listing which the user can expand/collapse, why not use javascript?	[reply]
