Can you see anything missing? Thank You Ok.. I have made an admin section for a couple of sites, and it works fine, alough i'm almost certain that the way i have done it is not the "proper way". What I have done is had a form with a password field that sends the password via POST to another script that checks the password is correct via variable, something like this: Code: [Select] <?php $pass = $_POST["pass"]; $correct = "imapassword"; if($pass == $correct){ //display contents of page else{ //return user to login screen } ?> And then it saves the password into a cookie, that dies either over time or when the browser closes. And then on each page it tests wether that cookie is still there and is correct. When the user wants to log out it just destroys the cookie. This seems like a really hashed up way of doing it, could anybody let me know the bare essentials for making a similar system, but the "right way". Thankyou in advance hi guys how you doing? i new here so take it easy on me . basically just need some quick help and i thought this would be the best place to ask. ive been working on a admin login script but cant seem to get it right, i mean i can login in with random passwords :/ and also everytime i go to the index.php it shows the information i dont want it without being logged in. ive got the script running live just incase anyone wants to see what i mean its at http://www.lukerodham.co.uk/admin heres the code.

I am trying to learn php and I cannot figure out how to get a simple login form going. I am getting this error.

Edited by Oblivion13, 07 October 2014 - 05:25 PM. Hi all, Sorry to be a pain, but I've been out of the php game for quite a few years and have just come back to it briefly to help someone out. I've been using an old admin auth script that I used to use a long time ago but it's not working, and I can't for the life of me work it out :/ I apologise for the noobishness of the code, but as I said, it's been a long time. Any and all help would be very greatly appreciated.

Also, I wanted to put protection on the page(s) that will send the user back to the login page if the credentials are nor correct. I would imagine the username/password would be stored in a database table (Admins), and the correct login info would be stored in a session ..? I am use to doing this with ASP, but never PHP. I want to make sure I understand how to do this properly and securely so I can use this as a model for other systems. In ASP I would do a protected page like this: a_login_check.asp Code: [Select] <% if session("admin_user_name") = "" then session.abandon response.redirect "login.asp" end if %> Protected-Page.asp Code: [Select] <!-- #include file="include/a_check_login.asp" --> <html> ... CONTENT ... </html> And of course there is the login page itself ... (I thought it would be nice to add a "Forgot Password" link on the login page, but if that is too complicated I can do that later .. or is it easy ??) Anyway, can someone point-out to me how to do this. I would appreciate it! Login.php Code: [Select] <?php session_start(); mysql_connect("localhost","root") or die(mysql_error()); mysql_select_db("cute") or die(mysql_error()); $username = $_POST['username']; $password = $_POST['pass']; if (isset($_POST["submit"])) { $log = "SELECT * FROM regis WHERE username = '$username'"; $login = mysql_query($log); $row = mysql_fetch_array($login); $number = mysql_num_rows($login); if ($number > 0) { $_SESSION['username'] = $row['username']; $_SESSION['userlevel'] = $row['userlevel']; if($_SESSION['userlevel']==1) { $_SESSION['is_logged_in'] == 1; header("Location: form2.php"); } else if($_SESSION['userlevel']== 0) { $_SESSION['is_logged_in'] == 1; header("Location: registration.php"); } } Registration.php Code: [Select] <?php echo 'Welcome:' .$_SESSION['is_logged_in'];?> form2.php Code: [Select] <?php session_start(); if (empty($_SESSION['is_logged_in'])) { header("Location:chatframe.php"); die(); // just to make sure no scripts execute } ?> <?php mysql_connect("localhost","root") or die(mysql_error()); mysql_select_db("cute") or die(mysql_error()); $message=$_POST['message']; $a=$_SESSION['username']; if(isset($_POST['submit'])) //if submit button push has been detected { if(strlen($message)>1) { $message=strip_tags($message); $IP=$_SERVER["REMOTE_ADDR"]; //grabs poster's IP $checkforbanned="SELECT IP from ipbans where IP='$IP'"; $checkforbanned2=mysql_query($checkforbanned) or die("Could not check for banned IPS"); if(mysql_num_rows($checkforbanned2)>0) //IP is in the banned list { print "You IP is banned from posting."; } else { $thedate = date("U"); //grab date and time of the post $insertmessage="INSERT into chatmessages (name,IP,postime,message) values('$a','$IP','$thedate','$message')"; mysql_query($insertmessage) or die("Could not insert message"); } } } ?> <html> <head> <script type="text/javascript"> function addsmiley(code) { var pretext = document.smile.message.value; this.code = code; document.smile.message.value = pretext + code; } function a() { var x = document.smile.message.value; if(x=="") { alert("Please insert an message!"); return false; } } </script> <style type="text/css"> body{ background-color: #d8da3d } </style> </head> <body> <form name="smile" method="post" action="form2.php" onSubmit="return a()" > Your message:<br><textarea name='message' cols='40' rows='2'></textarea><br> <img src="smile.gif" alt=":)" onClick="addsmiley(':)')" style="cursor:pointer;border:0" /> <img src="blush.gif" alt=":)" onClick="addsmiley('*blush*')" style="cursor:pointer;border:0" /> <input type='submit' name='submit' value='Send' class='biasa' ></form> <br> <br> </body> </html> In this registration.php when im called back its appear nothing im means the number is not showing and the login code even im had also put the "$_SESSION['is_logged_in'] == 1;" outside if else userlevel statement and then i put $d= $_SESSION['is_logged_in'] == 1; and im echoing back but it is nothing im thinks something wrong in session is login and also still it cannot redirect to admin -form2.php when session is login in is 1 Hi guy's, I'm having problems adjusting a script to add a level (user rights) function.

You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively in Unknown on line 0 Hello there, The problem is that my login system isn't consistent. There's an option of staying logged in, and if you check that a cookie gets created with a hash. When you visit the site again, you should be logged in automatically. But the thing is, that when you load the page, you aren't! But after a refresh you are logged in. So I'm guessing a problem in the order of things that get done... Here's the script: Code: [Select] <?php session_start(); if(isset($_COOKIE['LoginCookie'])) { $hash = $_COOKIE['LoginCookie']; mysql_select_db('database'); $sql = "SELECT all the info of the people FROM people WHERE cookie_hash = '".$hash."'"; if($result = mysql_query($sql)) { $row = mysql_fetch_array($result); if(empty($row)) { setcookie('LoginCookie','',time()-3600); } if(mysql_num_rows($result) == 1) { $_SESSION['loggedin'] = true; $_SESSION['loggedinnick'] = $row['nick']; $_SESSION['loggedinvoornaam'] = $row['voornaam']; $_SESSION['loggedinachternaam'] = $row['achternaam']; $_SESSION['loggedinid'] = $row['id']; $_SESSION['loggedintype'] = $row['type']; } } } if(isset($_POST['login'])) { if(empty($_POST['username']) || empty($_POST['wachtwoord'])) { $_SESSION['melding'] = 'ERROR'; header('Location: index.php'); exit(); } $username = CleanMyDirtyData($_POST['username']); $wachtwoord = sha1(CleanMyDirtyData($_POST['wachtwoord'])); mysql_select_db('database'); $sqlmail = mysql_query("SELECT * FROM people WHERE email='$username' AND wachtwoord = '$wachtwoord'"); $sqlnaam = mysql_query("SELECT * FROM people WHERE nick='$username' AND wachtwoord = '$wachtwoord'"); if(mysql_num_rows($sqlmail) == 1 || mysql_num_rows($sqlnaam) == 1) { if(mysql_num_rows($sqlmail) == 1) { $row = mysql_fetch_array($sqlmail); } else { $row = mysql_fetch_array($sqlnaam); } if(isset($_POST['remember'])) { $hash = sha1($username . 'Some secret thingys for your safety'); setcookie('LoginCookie',$hash,time()+30000000); mysql_query("UPDATE leden SET cookie_hash='" . $hash . "' WHERE id='" . $row['id'] . "'")or die(mysql_error()); } $_SESSION['loggedin'] = true; $_SESSION['loggedinnick'] = $row['nick']; $_SESSION['loggedinvoornaam'] = $row['voornaam']; $_SESSION['loggedinachternaam'] = $row['achternaam']; $_SESSION['loggedinid'] = $row['id']; $_SESSION['loggedintype'] = $row['type']; $_SESSION['melding'] = 'You are logged in now.'; } else { $_SESSION['melding'] = 'ERROR'; header('Location: index.php'); exit(); } } So if the checkbox that you want to stay logged in, there is no cookie made but the $_SESSION['loggedin'] is set to true. Throughout the rest of the page, this parameter is used to show either content for guests of private content for people that are logged in. BUT the problem is that if it is checked on the first page load the $_SESSION['loggedin'] doesn't seem to get set even though the cookie is set. Another slight problem with my script is that when a user logs in on another pc, the hash get's changed in the database and the user gets logged out of the site on the previous page. What is the easiest way to do that? And do you guys think this script is safe? Or do you see some holes? Thanks in advance! arbitter |
