if($_SESSION['user_id']==1)
  {

      //put user links here.

      }
 if($_SESSION['user_id']==1)
  {

      //put admin links here.

1. Have session_start() at the top of every page straight after the '<?php' bit - before the DTD.
2. Use

if(isset($_SESSION['level'])){
   switch($_SESSION['level']){
      case 1:
         ...do something...
         break;
      case 2:
         ...do something...
         break;
      case 3:
         ...do something...
         break;
      case 4:
         ...do something...
         break;
   }
}else{
  ...do if not set...
}

Alternatively you could use multiple elseifs.

The correct switch()/case: structure is

switch($var) {
    case 1:
    //do something
    break;
    case 2:
    //do something else
    break;
}

What you did was this:

switch($var) {
    case 1:
    //do something
    if($othervar)
    //do something
    break;
}

Change it to this:

switch($_SESSION['level']) {
    case 9:
        // show admin links
    break;
    case 1:
        // show user links (remember ending ";"... you don't have one in your code).
    break;
    default:
        // show guest links
}

Or, you could remove the "break;" if you wanted the admin, for instance, to also see the user links, or the users to also see the guest links.
How it works is that PHP goes thru the cases, and jumps into the code once it finds a case that's true. After that, it will process all the code until it comes to the end of the code block or a break; statement (whichever comes first). So, place your admin "case" at the top of the list, and you don't really need the if(isset($_SESSION['level'])){} , since it will only show what comes after the "default:" special case.
