Order filepath into serchnew.php

[Andrea76]

This is the part of code that i think to must modify but i don't be able to do...  :-\

function display_dir_tree($folder, $ident)
{
    global $CONFIG, $PHP_SELF, $lang_search_new_php;
    $dir_path = $CONFIG['fullpath'] . $folder;


    if (!is_readable($dir_path)) return;

    $dir = opendir($dir_path);
    while ($file = readdir($dir)) {
        if (is_dir($CONFIG['fullpath'] . $folder . $file) && substr($file,0,1) != "." && strpos($file,"'") == FALSE && $file != substr($CONFIG['userpics'],0,strlen($CONFIG['userpics'])-1)  && $file != "edit" ) {
            $start_target = $folder . $file;
            $dir_path = $CONFIG['fullpath'] . $folder . $file;

            $warnings = '';
            if (!is_writable($dir_path)) $warnings .= $lang_search_new_php['dir_ro'];
            if (!is_readable($dir_path)) $warnings .= $lang_search_new_php['dir_cant_read'];

            if ($warnings) $warnings = '&nbsp;&nbsp;&nbsp;<b>' . $warnings . '<b>';

            echo <<<EOT
                        <tr>
                                <td class="tableb">
                                        $ident<img src="images/folder.gif" alt="" />&nbsp;<a href= "$PHP_SELF?startdir=$start_target">$file</a>$warnings
                                </td>
                        </tr>
EOT;
            display_dir_tree($folder . $file . '/', $ident . '&nbsp;&nbsp;&nbsp;&nbsp;');
        }
    }
    closedir($dir);
}

How can I sort the list by filepath? 
The list is randon and not by foldername!!!
Please help me! :'(

PS in this code I find a modify of GAUGAU ... is he the magic codifyer?

I'm the editor of the line that has the comment only. Coppermine is a team effort, with the basics of the code you're refering to being done by Gregory Demar.
Cpg1.4.x has a browsable batch-add interface with alphabetical sorting, I suggest upgrading instead of trying cpg1.3.x
