Navigation Menu

[Sharky01276]

Ok im getting my self really confused i think im thinking way to complicated about this. Basically i want a very simple navigation menu with multiple levels eg.

 

PHP

About

History

Syntax

  String

  Integer

  Arrays

Mysql

About

History

  Versions

    5.1

    5.2

Syntax

 

So when php is clicked the next set of options is shown. Then when Syntax is show the next options are shown. Im quite happy for the page to be reloaded to do this. For the life of me i cant think of the way of doing this. Ive tried using trees and nodes but im getting my self confused.

 

Any help would be appreciated thanks

i made this a while ago... maybe ya can find it useful to look at...

 

$query=db_query("SELECT * FROM `categories` WHERE `sub`='' ORDER BY `name`");
$categories=array();
while($row=mysql_fetch_array($query)){
if(!empty($row[secure])) if(!secure($row[secure])) continue;
if($_GET[cat]==$row[id]){
  $categories[]='<a href="?op=products&cat='.$row[id].'" class=title>'.ucwords($row[name]);
  $query2=db_query("SELECT * FROM `categories` WHERE `sub`='$row[id]' ORDER BY `name`");
  while($row2=mysql_fetch_array($query2)){
   if(!empty($row2[secure])) if(!secure($row2[secure])) continue;
   if($_GET[sub]==$row2[id]) $categories[]='<a href="?op=products&cat='.$row[id].'&sub='.$row2[id].'" class=subtitle><span class=subcat>'.ucwords($row2[name]).'</span></a>';
   else $categories[]='<a href="?op=products&cat='.$row[id].'&sub='.$row2[id].'"><span class=subcat>'.ucwords($row2[name]).'</span></a>';
  }
}else $categories[]='<a href="?op=products&cat='.$row[id].'">'.ucwords($row[name]).'</a>';
}
sort($categories);
$left=implode("<br>",$categories);
