php - Unsuccessful Login

Question

I have tried login and it didn't work, when I login, it just stay at the blank page. No errors has shown.

I have made a form in index.php. If the user hasn't logout, the name of user will output on the page. And if the user hasn't login, it will show a login form. The following code below:

<div class="topRight">
        <?php
            ini_set('display_errors',1); 
            error_reporting(E_ALL);
            include "config/dbconnect.php";

            if(isset($_SESSION['login'])&&!empty($_SESSION['login'])) {            
                $name = $_SESSION['user_info']['name'];
                echo '<p> <a href="profileUser"> Profile : $name </a>';
                } else {
                echo    '<form action="actions/login.php" method="POST">
                            <input type="text" name="email" placeholder="Email">
                            <input type="password" name="password" placeholder="Password">
                            <input type="submit" value="LOGIN">
                        </form>';
                echo    '<p> <a href="registerForm.php" class="underline"> Not a member? Register here! </a> </p>
                        <p> <a href="actions/logout.php"> Logout </a> </p>';
            }
        ?>
    </div>

After login, it will directly to login.php as shown as below:

<?php
  ob_start(); 
  session_start();
  ini_set('display_errors', 1);
  error_reporting(-1);
?>

<?php
include "../config/dbconnect.php";

    if(isset($_POST['submit'])) {
        $username = trim($_POST['email']);
        $password = trim($_POST['password']);

        $username = $mysqli->real_escape_string($username);
        $password = $mysqli->real_escape_string($password);

        $salt = sha1(md5($password));
        $epwd = md5($password.$salt);

        $loginUser = "  SELECT * FROM memberTable
                        WHERE email = '$email' AND password = '$epwd'";

        $loginSuccess = mysqli_query($mysqli, $loginUser) or die(mysqli_error($mysqli));
        $loginRow = mysqli_num_rows($loginSuccess);

        if($loginRow === 1) {

            session_start();
            $_SESSION['login'] = true;

            $user_info = mysqli_fetch_assoc($loginSuccess);
            $_SESSION['user_info'] = $user_info; // put user_info to call all details for later use

            header ("Location: ../index.php");
            } else {
                header ("Location: ../header.php");
            }

    mysqli_close($mysqli);
    }
?>

The following code for dbconnect.php is below:

<?php
    //Open a new connection to the MySQL server
    $mysqli = new mysqli('localhost','root','root','database_name');

    //Output any connection error
    if ($mysqli->connect_error) {
        die('Error : ('. $mysqli->connect_errno .') '. $mysqli->connect_error);
    }
?>

The result is when I sign in with a form, it successfully navigate to login.php. But it just stopped there with a blank page and not redirecting to index.php. There are no error has shown.

What I have done is:

1. I simply put ini_set('display_errors',1); and it still not showing any errors.
2. I have checked dbconnect.php, and the connections between index.php and login.php to dbconnect.php is linking very well.

Still it didn't show any sign like this screenshot. Am I missing something?

Answer 1

header ("Location: ../index.php"); needs to be fallowed by an exit statement

header("Location: ../whatever.php");
exit;
