I'd suggest using the is_dir() function in your while() loop.

Eg:

PHP Code:


			
<?php 

if ($handle = opendir('../categories/')) { 

    /* loop through directory. */ 

    while (false !== ($dir = readdir($handle))) {

        if (is_dir($dir))

        {

            echo '<option value='.$dir.'>'.$dir.'</option>'; 

        }

    } 

    closedir($handle); 

} 

?>

In theory, this should skip anything that isn't a directory.

Note: '.' and '..' are considered directories so you might want to strip them as well

Alan.
