elseif($_POST["page"] == "users_login")
{
$user_utilizador = trim(strip_tags($_POST['email']));
$user_password = trim(strip_tags($_POST['passwd']));
$encrypted_md5_password = md5($user_password);
$validate_user_information = mysql_query("select * from `utilizador` where `utilizador` = '".mysql_real_escape_string($user_utilizador)."' and `password` = '".mysql_real_escape_string($encrypted_md5_password)."'");
echo $validate_user_information;
if(mysql_num_rows($validate_user_information) == 1)
{
$get_user_information = mysql_fetch_array($validate_user_information);
$_SESSION["VALID_USER_ID"] = $user_utilizador;
$_SESSION["USER_FULLNAME"] = strip_tags($get_user_information["nome"]);
echo 'index.php?uid='.$_SESSION["USER_FULLNAME"].'&';

$user_matched = mysqli_num_rows($result);
// Check If user matched/exist, store user email in session and redirect to sample page-1
if ($user_matched > 0) {
$_SESSION["email"] = $email;
header("location: welcome.php");

This topic has been moved to Third Party PHP Scripts. http://www.phpfreaks.com/forums/index.php?topic=349834.0 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 ?> |
