hi


this is a  simple and crude php code to redirect the user according to roles in drupal

this can be used in drupal hook_user function or panels pages to redirect the user

 <?php  
 global $user;  
 //consider two roles moderator and regular user  
 //moderator role rid is 2  
 //regular user role rid is 4  
 if($user){  
 //roles item is array  
 if($user->roles[2]){// if user has a role moderator  
 //do this  
 drupal_goto("user/moderater-panel");// redirecting  
 }elseif ($user->roles[4]){ // user user have role regular user  
 drupal_goto("user/regular-panel");// redirecting  
 }else{ // if the user have other roles then above roles do this  
 //do smothing  
 }  
 }
