Answer 1

Replace the line

<form method="post" action="" class="form-horizontal">

with

<form method="post" action="#" class="form-horizontal">

or

<form method="post" action="yourfilename.php" class="form-horizontal">

or

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" class="form-horizontal">

Answer 2

First , that Code would Only run If you Login Details are Found Correct And Matched a Row in a Database

Second , Kindly Update this Code

'select email, password from user where email = :email and password = :password'

to

"SELECT email, password FROM user WHERE email = '$email' and password = '$password'"

Lastly , header('Location: index.php');

I Hope this works...

Here you go...

<?php  
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Connection Query
    $db = new Database();
    // Fetch Login Data
    $email = $_POST['email'];
    $pass = $_POST['password'];
    // Login Query
    $login = "SELECT email, password FROM user WHERE email='$email' and password='$pass'";
    // Query SQL
    $req = mysqli_query($db, $login);
    // Check if Row matched is Above Zero
    if (mysqli_num_rows($req) > 0) {
        // Redirect User
        header("Location: index.php");
    }
}
?>
