I just want to populate a multilevel dropdown menu which uses mysql and php using single table

sample menu url: http://www.vidiyarkarai.com/

(sorry for this i tried to include an image but i'm not allowed to upload images, please see the menu using above address, please never mind the language in that site...)

i just want to generate this type of menu using a single table, i did this using multiple tables which is not effective and slow in some cases, so i want to do it in a single table.

  /*menu should be like 

  - menu_name(show if parent_id=0) // parent id is 1 for this id --- level1
    -> menu_name(show if parent_id=1) // parent id is 2 for this id  --- level2
        ->-> menu_name(show if parent_id=2) // parent id is 3 for this id  --- level3
   */
            --
            -- Table structure for table `tm_menu`
            --

            CREATE TABLE IF NOT EXISTS `tm_menu` (
              `menu_id` int(10) NOT NULL,
              `menu_name` varchar(300) DEFAULT NULL,
              `menu_desc` text,
              `menu_link` varchar(300) DEFAULT NULL,
              `item_id` int(10) DEFAULT NULL,
              `item_pos` varchar(10) DEFAULT NULL,
              `parent_id` int(10) DEFAULT NULL,
              `created_by` varchar(100) DEFAULT NULL,
              `updated_by` varchar(100) DEFAULT NULL,
              `created_on` datetime DEFAULT NULL,
              `updated_on` datetime DEFAULT NULL,
              `ip` varchar(100) DEFAULT NULL,
              `status` tinyint(1) DEFAULT NULL,
              PRIMARY KEY (`menu_id`)
            ) ENGINE=MyISAM DEFAULT CHARSET=latin1;

            --
            -- Dumping data for table `tm_menu`
            --

FYU i include the sample data, please never mind about the language included with it

    INSERT INTO `tm_menu` (`menu_id`, `menu_name`, `menu_desc`, `menu_link`, `item_id`, `item_pos`, `parent_id`, `created_by`, `updated_by`, `created_on`, `updated_on`, `ip`, `status`) VALUES

I do this using a recursive function, something along the lines of:

function get_pages ($parent_id='') {
  if ($parent_id == '') {     // if first call to function there's no parent id
    $pages = list of pages from db //use your own code here to pull all cats with no parent
  }
  else {
    $pages = list of pages with $parent_id as their parent_id
  }

  echo "<ul>";  //open list
  foreach ($result as $page) {
    echo "<li><a href=' << path to this page >> '></li>";
    $query = code to check for pages with this page as their parent
    if (query returns a result - ie there are sub pages) {
      get_pages($page['id']);  // this is the key, the function calls itself passing the current page as the parent so it only gets the sub pages
    }
  }
  echo "</ul>";
}

You need to learn how to store trees in databases effectively.

You should use Nested Sets data structure for tree-like menus. It will save lots of sql queries.

See the discussion about Nested Sets here: Searching for the best PHP nested sets class (PEAR class excluded)
