change session name..try this

change in login_check.php

<?php if ( $role == "admin") {  $_session['adminuser']=$_post['name']; header("location:admin_home.php"); } else  if ( $role == "member") { header("location:member_home.php"); $_session['user']=$_post['name']; } 

?>

change in member_home.php

<?php session_start(); if (!isset($_session['user'])){ header('location:index.php'); } ?> 

change in admin_home.php

<?php session_start(); if (!isset($_session['adminuser'])) { header('location:index.php'); } ?> 

try this

$_session['name'] = $variab;// array variable print_r($_session['name'][0]);
