Can someone tell me how to get my registration page to start out fresh.

Can someone tell me how to get my registration page to start out fresh.  For example, let say a user tries to register but the password fields are not identical. That person would recieve a message saying passwords are not identical.  So that person tries again and types in identical passwords but the username already exists. Even though the passwords match, that person will still recieve two messages one from before,"the password is not identical" and "the username is already in use".???  Its like my registration page isn't refreshed. It shows old error messages.

 

 

here is my code

<?php
session_start();
Header("Cache-control: private, no-cache");
Header("Expires: Mon, 26 Jun 1997 05:00:00 GMT");
Header("Pragma: no-cache");

//checks for identical passwords
if($_POST["password"]!==$_POST["confirmpassword"]){
        $_SESSION['identical'] = "Passwords are not identical.";
	header("Location: registration.php");
}  else {
$mysqli = mysqli_connect("localhost", "root", "", "test");
}
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
// checks if the username is in use
if (!get_magic_quotes_gpc()) {
$_POST['username'] = addslashes($_POST['username']);
}

$usercheck = $_POST['username'];
$check = mysqli_query($mysqli,"SELECT username FROM auth_users WHERE username = '$usercheck'"); 
$check2 = mysqli_num_rows($check);

//if the name exists it gives an error
if ($check2 != 0) {
$_SESSION['userExists'] = "<font color='red'>" .$_POST['username']. " is already in use. Please choose another username.</font>";	
    header ("Location: registration.php");

}  else  {

$sql = "INSERT INTO auth_users (username, password, ConfirmPassword, f_name, L_name, address, city, state, zip, phoneNumber, AltphoneNumber, email, company) VALUES ('".$_POST['username']."',PASSWORD('".$_POST["password"]."'),PASSWORD('".$_POST["confirmpassword"]."'),'".$_POST['firstname']."','".$_POST['lastname']."','".$_POST['address']."','".$_POST['city']."','".$_POST['state']."','".$_POST['zip']."','".$_POST['phone']."','".$_POST['alternate']."','".$_POST['email']."','".$_POST['company']."')";
$res = mysqli_query($mysqli, $sql);

}
if ($res === TRUE) {
	header("Location: registered.html");
	} else {
printf("Could not insert record: %s\n", mysqli_error($mysqli));
}
mysqli_close($mysqli);

?>

I don't really understand what you are asking, but if you are wanting to be able to record many different errors I use an "error handler".  you could also use it as an array or anything else.

There are hundreds of way's, this is just one quick example off of something quick, just so you can see one possibility.
