paddyhaig Posted May 19, 2010 Share Posted May 19, 2010 What I have, and what I am trying to achieve. I have a web app that I created and seemed to work about 7 years ago. However I rebuilt the app using css, as it had been using html tables prior. And now it seems that I have some kind of problem locking an authenticated user into his own account. If you manually alter the URL you can now get into the other account folders. (This I obviously don't want) I have a regular 'index.php' form. Here is the relevant code in that form. form action="scripts/authenticate/auth.php" method="POST"> Account: <input name="account" type="text" id="account" value="[email protected]" Username: <input name="username" type="text" id="username" size="20"> Password: <input name="password" type="password" id="password" size="20"> Here is the auth.php script <?php if (isset($_POST['username']) && isset($_POST['password'])) { $db = mysql_connect('localhost', 'example', 'example') or die("Couldn't connect to the database<br>" . mysql_error()); mysql_select_db('example', $db) or die("Couldn't select<br>" . mysql_error()); $login = mysql_real_escape_string($_POST['username'], $db); $password = mysql_real_escape_string($_POST['password'], $db); $query = "SELECT privilage FROM auth WHERE login = '$login' AND password = '$password'"; $result = mysql_query($query, $db) or die("Problem with the query: $query<br>" . mysql_error()); if (0 === mysql_num_rows($result)) { header('Location: ../../index.php'); exit(0); } $row = mysql_fetch_assoc($result); $privilage = $row['privilage']; session_start(); $_SESSION['username'] = $login; $_SESSION['privilage'] = $privilage; if ('receptionist' === $privilage) { header('Location: ../../receptionists/index.php'); exit(0); } if ('manager' === $privilage) { header('Location: ../../managers/index.php'); exit(0); } if ('administrator' === $privilage) { header('Location: ../../admin/index.php'); exit(0); } } ?> This seems to create a cookie in my browser, here are the cookie details. Name PHPSESSID Value p2r4il0jeadghdoa7h4hb7uku5 Host www.example.com Path / Secure No Expires At End Of Session The really is nothing else in the pages, I do believe I should have something starting with: session_start(); at the top of every page, so's to check the cookie? I have also included a graphic of my mySQL db schema. Please see atached. schema.jpg The have been a number of suggestions that I have tried that do not seem to work. Please anyone with a good knowledge of this area please help me. I am almost at my wits end. Thank you. Also if your going to reply please keep it easy as this is just a part time hobby to me.

andrewgauger Posted May 21, 2010 Share Posted May 21, 2010 It might be a problem with the header redirect. You probably want to use ob_start() http://php.net/manual/en/function.ob-start.php The way to test for this is instead of changing the location of the page put a simple echo for each of the roles, and verify that the authentication is successful. It looks OK to me. Link to comment https://forums.phpfreaks.com/topic/202310-php-mysql-authentication-problems-and-issues/#findComment-1061499 Share on other sites More sharing options...
paddyhaig Posted May 21, 2010 Author Share Posted May 21, 2010 Thank you andrewgauger, all though I am not altogether sure what you are saying, that's probably more my fault than yours. Are you saying that I should put ob_start() at the top of every page? Just ob_start()? You must excuse me as I really am new to this.

andrewgauger Posted May 21, 2010 Share Posted May 21, 2010 Yeah at the top, and then put an ob_end_flush between your header() and exit() funcitons Link to comment https://forums.phpfreaks.com/topic/202310-php-mysql-authentication-problems-and-issues/#findComment-1061682 Share on other sites More sharing options...
paddyhaig Posted May 21, 2010 Author Share Posted May 21, 2010 Thank's andrewgauger! So at the very top of every page I should put an ob_start() e.g. <!-- This is the beggining of the authentication addition --> ob_start() <!-- This is the end of the authentication addition --> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Concierge Admin Index</title> <link href="../includes/primary_layout.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="wrapper"> <div id="large-blue-box"> <div id="form1"> <!-- <?php include("../includes/footer.inc"); ?> I would like to make all the below code an include --> <p><img src="../graphics/general/ai_banner.gif" alt="" width="180" height="28" /></p> <p><a href="concierge-setup.php"><img src="../graphics/general/concierge-setup_button.gif" width="180" height="28" /></a></p> <p><a href="accommodation.php"><img src="../graphics/general/accomodate_button.gif" width="180" height="28" /></a></p> <p><a href="general-log.php"><img src="../graphics/general/gen-log_button.gif" width="180" height="28" /></a></p> <p><a href="../index.php"><img src="../graphics/general/lo_button.gif" alt="" width="180" height="28" /></a></p> </div> <div id="form2"> <p><img src="../graphics/general/man_index_banner.gif" width="180" height="28" /></p> <p><a href="staff_management.php"><img src="../graphics/general/sm_button.gif" width="180" height="28" /></a></p> <p><a href="bed_management.php"><img src="../graphics/general/bm_button.gif" width="180" height="28" /></a></p> <p><a href="audit_system.php"><img src="../graphics/general/as_button.gif" width="180" height="28" /></a></p> <p><a href="shift_summary.php"><img src="../graphics/general/shift-summary_button.gif" width="180" height="28" /></a></p> </div> <div id="form3"> <p><img src="../graphics/general/recep_banner.gif" width="180" height="28" /></p> <p><a href="check-in-out_index.php"><img src="../graphics/general/check-inout_button.gif" width="180" height="28" /></a></p> <p><a href="delinquent_payments.php"><img src="../graphics/general/delinquent-payments_button.gif" width="180" height="28" /></a></p> <p><a href="reservations.php"><img src="../graphics/general/reservations_button.gif" width="180" height="28" /></a></p> <p><a href="misc_index.php"><img src="../graphics/general/miscellaneous_button.gif" width="180" height="28" /></a></p> </div> </div> <?php include("../includes/footer.inc"); ?> </div> </body> </html> andrewgauger Yeah at the top, and then put an ob_end_flush between your header() and exit() funcitons I don't have a header and exit function.

andrewgauger Posted May 23, 2010 Share Posted May 23, 2010 On auth.php where you direct the page depending on privilege. Link to comment https://forums.phpfreaks.com/topic/202310-php-mysql-authentication-problems-and-issues/#findComment-1062093 Share on other sites More sharing options...
