}else{
$result = mysql_query("SELECT * FROM d_menu_left WHERE parentId = 0  AND publish = 'YES'  ORDER by sortkey");
}
echo "<ul>\n";//yderste ul
while($data = mysql_fetch_array($result)){ //yderste while
echo "    <li> <a href='$_SERVER[PHP_SELF]?id=$data[id]'>$data[category_name](id=$data[id]-parentId=$data[parentId])</a>\n";

if($_SESSION["auth"] == 1){
$sqlresult = mysql_query("SELECT * FROM d_menu_left WHERE $data2[id] = parentId  ORDER by sortkey");
