after validating the data of a registration form, redirect to another page to connect
advertisements
i am new to php and mysql. I am trying to create a user registration form, validate the data, and then redirect to a login page, where they can enter their username and password to sign in. i have written the codes, but for some reason i'm not able to use the header() properly. Here is my code so far:
$userErr= $passErr= $passErrc= $firstErr= $lastErr= $middle= $addErr= $cityErr= $stateErr=$zipErr= $emailErr= $phoneErr= $passMatchErr="";
$userID= $password= $pass_conf= $firstName= $lastName= $middle= $address= $city= $state= $zip= $email= $phone="";
// Validate the form
// use trim() function to remove unnecessary characters such as extra space, tab, newline,
// use stripslashes(() to remove backslashes
// use htmlspecialchars() for security
function test_input($data)
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
// validating the form to see all required fields are entered
if (empty($_POST["userID"]))
{
$userErr = "User ID is required";
}
else
{
$userID = test_input($_POST["userID"]);
}
if (empty($_POST["password"]))
{
$passErr = "Password is required";
}
else
{
$password = test_input($_POST["password"]);
}
if (empty($_POST["pass_conf"]))
{
$passErrc = "Confirm your password";
}
else
{
$pass_conf = test_input($_POST["pass_conf"]);
}
if (empty($_POST["firstName"]))
{
$firstErr = "First Name is required";
}
else
{
$firstName = test_input($_POST["firstName"]);
}
if (empty($_POST["lastName"]))
{
$lastErr = "Last Name is required";
}
else
{
$lastName = test_input($_POST["lastName"]);
}
if (empty($_POST["middle"]))
{
$middle = "";
}
else
{
$middle= test_input($_POST["middle"]);
}
if (empty($_POST["address"]))
{
$addErr = "Address is required";
}
else
{
$address = test_input($_POST["address"]);
}
if (empty($_POST["city"]))
{
$cityErr = "City is required";
}
else
{
$city = test_input($_POST["city"]);
}
if (empty($_POST["state"]))
{
$stateErr = "State is required";
}
else
{
$state = test_input($_POST["state"]);
}
if (empty($_POST["zip"]))
{
$zipErr = "Zip is required";
}
else
{
$zip = test_input($_POST["zip"]);
}
if (empty($_POST["email"]))
{
$emailErr = "Email is required";
}
else
{
$email = test_input($_POST["email"]);
}
if (empty($_POST["phone"]))
{
$phoneErr = "";
}
else
{
$phone = test_input($_POST["phone"]);
}
}
else
{
if($password != $pass_conf){
$passMathErr= "Passwords do not match. Please, go back and re-enter the passwords!";
// die($passMathErr);
} else{
// perform sql query to insert the data
$sql="insert into users values('$userID', '$password', '$firstName', '$lastName', '$middle', '$address', '$city', '$state', '$zip', '$email', '$phone')";
$result=mysql_query($sql, $connection);
header("Location:login.html");
}
}

You have to exit from the code segment once the control is transferred to another page. Otherwise the following code will get executed. So use exit; after header().
header("Location:login.html");
exit;
