restricting another login once you logout

Posted on 16th Feb 2014 07:03 pm by admin

Hello,

how can I restrict a page from login authenticating against info in a MySQL DB for a second time? Right now a login check against username and password in a MySQL table and allows access against that data. This works fine, but I want to disallow access once a person has logged in once and logged out.

My current code


<?php
//ini_set("display_errors","1");
//ERROR_REPORTING(E_ALL);

session_start();
/*logout after 65 minutes*/
function login_validate() {
/*Set the timeout on a login session. */
/*Default timout is ten minutes (600 seconds). */
$timeout = 15;
$_SESSION["expires_by"] = time() + $timeout;
}

$con = mysql_connect("localhost","ETSI","Editor") or die('Could not connect: ' . mysql_error());

mysql_select_db("ETSI_Internal") or die(mysql_error());
