PHP - Login Page Error

Can someoneplease help, I need to setup an error page like IF Username and Password are wrong then show an error also if there is no username or password in the fields and I just click LOGIN, I get a blank page?!

Can someone please help me here or point me to a relevant tutorial?

thanks

here is my page:
http://www.retroandvintage.co.uk/default.php

here is my  code:
Code: [Select]
<?php
session_start();
include_once("config.php");

$ebits = ini_get('error_reporting');
error_reporting($ebits ^ E_NOTICE);
/*
Login script:
This script does the following:

Checks that the user is NOT already logged in - if they are they
are redirected to the members page by the 'checkLoggedIn()' function.

Checks if the login form has been submitted - if so, the 'login' and
'password' fields are checked to ensure they are of the correct format and length.
If there are any problems here an error is added to the $messages array and
then the script executes the 'doIndex()' function - this function basically
outputs the main 'index' page for this script - ie the login form.

If there are no problems with the previous step, the 'login' and 'password'
field data is passed to the 'checkPass' function to check that an entry
exists in the 'users' table for that login/password pair.
If nothing is returned from the 'checkPass()' function, an error is
added to the $messages array and the 'doIndex()' function is called as above.

If a row of data is returned from the 'users' table, the data is passed to
the 'cleanMemberSession()' function - which initializes session variables and
logs the user in.  The user is then forwarded to the members page.

If the form hasn't yet been submitted, then the 'doIndex()' function is called
and the login page is displayed.
*/
// Check user not logged in already:
checkLoggedIn("no");

// Page title:
$title="Member Login Page";

// if $submit variable set, login info submitted:

// show the index page (where the messages will be displayed):

// the lines below will be processed:

If checkPass() is successful (ie the login and password are ok),
then $row contains an array of data containing the login name and
password of the user.
If checkPass() is unsuccessful however, $row will simply contain
the value 'false' - and so in that case an error message is
stored in the $messages array which will be displayed to the user.
*/
    if( !($row = checkPass($_POST["rsUser"], $_POST["rsPass"])) ) {
// login/passwd string not correct, create an error message:
        $messages[]="Incorrect login/password, try again";
    }

/*
If there are error $messages, errors were found in validating form data above.
Call the 'doIndex()' function (which displays the login form) and exit.
*/
if($messages){
doIndex();
exit;
}

/*
If we got to this point, there were no errors - start a session using the info
returned from the db:
*/

Hello all, my first post after joining this very informative site, unfortunatly I was unable to find the answer to my simple yet frastrating dilemma.

I am in the process of building a website that will enable users to log-in through a dedicated loginU.php page, I have all of this working but I would like to display an error message on this page saying if the user has entered a wrong username/password, I have the message displaying on a blank white page, but I would like it to be displayed within the container I have created. the validation code is contained within a different login.php file.

At the moment I am using an iframe to display the messages, which I know is not the right way to do it, so am asking for a better way to do it. here is what I have so far:

loginU.php
Code: [Select]
<div id = "div-Login">
<form action="login.php"  method="POST" target="loginerror">
<center><h2>Login Here</h2> <p>
Username:  <input type="text" name="username"><p>
Password:  <input type="password" name="password"><p>
<input type="submit" name="submit" value="Login">
</center>
<a href="register.html"><pre>need to register? Click Here!</pre></a>
</form>

<iframe name="loginerror" style="border: 0px; width: 200px; height: 100px; overflow: hidden;" src="login.php"></iframe>
</div>

login.php
Code: [Select]
if ($username==$dbusername&&$enc_password==$dbpassword) //if the username & encrpyted password matches the records in the database
{
if($admin !=0) //if the admin flag is true
{
$_SESSION['level']='ADMIN';//admin is logging in
header ("Location: admin.php"); //the user is an admin, direct to admin page
}
else
header ("Location: index.php"); //user is a customer, direct user to index page
$_SESSION['username']=$dbusername; //set the session name to the database record username.
}
else
//$nopass='TRUE';
//header ("location: loginU.php");
echo "Incorrect Password, Please try again"; // if incorrect password
}
else
die ("That username doesn't exist"); // if user doesn't exist
}
else
die ("Please enter a username and password"); //if either field is empty

?>

Hello everyone,

When I submit my login form to go to my login page it goes to a white page and does not display an error.

Code: [Select]
<?php 
include("../secure/database.php");

if(!empty($_POST['loginsubmit'])){
if(!empty($_POST['email'])){

$email = securevar($_POST['email']);

if(!empty($_POST['passconf'])){

$pass = securevar($_POST['passconf']);

$q = "SELECT * FROM `accountinfo_db` WHERE `email` = '$email' AND `password` = '$pass'";

$res = mysql_query($q) or die(mysql_error());

$login = mysql_fetch_array($res);
$id = $login['id'];
$active = $login['active'];
if($id>=1){
if($active==1){
$_SESSION['logged'] = $login['id'];

$q = "UPDATE `accountinfo_db` SET `loggedtimes` = `loggedtimes`+'1' WHERE `id` = '$id'";
$res = mysql_query($q) or die(mysql_error());
$user = $login['username'];
header("Location: ../mainframe.php?strmsg=Welcome Back $user");
}else{
header("Location: activate.php");
}

}else{
   header("Location: ../index.php?strmsg=Login Information Incorrect!");    
}

       }else{
   header("Location: ../index.php?strmsg=You did not enter a valid password!");    
   }
   }else{
   header("Location: ../index.php?strmsg=You did not enter a valid email!");
   }
}else{
header("Location: ../index.php?strmsg=We are sorry but you are not allowed viewance of that directory!");
}
?>

any help would be great.

hi

i need help an idea how can i separate members from admins
since i dont know how to create login form i used tutorial ( http://www.youtube.com/watch?v=4oSCuEtxRK8 )   (its session login form only that i made it work other tutorials wre too old or something)
how what i want to do is separate members and admins because admin need more rights to do
now i have idea but dont know will it work like that
what i want to do is create additional row in table named it flag and create 0 (inactive user) 1 (member) 2 (admin) will that work?
and how can i create different navigation bars for users and admins? do you recommend that i use different folders to create it or just script based on session and flag?

I keep getting an error code when running my php, it states:


Parse error: syntax error, unexpected $end in W:\www\blog\login.php on line 33

$num = mysql_num_rows($result);
if($num == 0){
echo "Bad login, go <a href='login.php'>back</a>";
}else{
session_start();
$SESSION ['name'] = $name;
