the html is wrong, option doesn't have an attribute of name, select has the name, option has
the value.
try it like this, the result will be in $files
<?php
$dir_name = "/path/to/images/directory/";
$dir = opendir($dir_name);
$file_list .= "<p><FORM METHOD=\"post\"
ACTION=\"index_done.php3\">
<SELECT NAME=\"files\">";
while ($file_name = readdir($dir)) {
if (($file_name != ".") && ($file_name !="..")) {
$file_list .= "<OPTION VALUE=\"$file_name\">$file_name</OPTION>";
}
}
$file_list .= "</SELECT><br><br><INPUT TYPE=\"submit\"
NAME=\"submit\"
VALUE=\"select\"></FORM></p>";
closedir($dir);
?>
