Question

I am having trouble redirecting my code to another page after a correct username/password has been submitted. After I enter the username/password and hit submit, the page does not redirect.

The page just reloads and clears the field inputs (even though it's a sticky form), and stays at the same page, except the URL adds ?submit=Submit to the end of the URL..

I am not getting any mysql errors - the database is connecting fine at the query that matches the row with the username/password combo seems to be going through.

It should be looping through the database, checking if the username/password combo exists, and redirecting to the specified page. I'm not sure what I'm not seeing / missing here that keeps the page from redirecting. Any input would be greatly appreciated.

PHP:

<?php
        define('DB_LOCATION', 'x');
        define('DB_USERNAME', 'x');
        define('DB_PASS', 'x');
        define('DB_NAME', 'x');

        $dbc = mysqli_connect(DB_LOCATION, DB_USERNAME, DB_PASS, DB_NAME)
            or die('Error connecting to database');

    $error_message= "";

    if (isset($_POST['submit'])) {

        $user_name = $_POST['user'];
        $user_password= $_POST['pass'];


        // ADD QUERY TO CHECK IF USER/PASS COMBO IS CORRECT
        if(!empty($user_name) && !empty($user_password)) {

        $query = "SELECT * FROM employees WHERE username='$user_name' and password='$user_password'";

        $result = mysqli_query($dbc, $query)
            or die ('Error querying username/password request');

            if(mysqli_num_rows($result) == 1) {

                $user_name = $row['user'];
                $user_password = $row['pass'];

                header("Location: www.mysite.com ");

            } // end if rows

            else {
                $error_message = "You were not able to log in";
            } // end else


        } // end query


    } // end isset

?>

Answer 1

Remove <form>, just before <div id="table2">, and </form> as well.

Answer 2

Remove <form> and </form> just before <div id="table2"> but i say you create a simple function which handles the redirects like below.

why don't you try something like this which creates a function for the redirect.

function Redirect($url, $permanent = false)
{
    header('Location: ' . $url, true, $permanent ? 301 : 302);
    exit();
}

Redirect('Location: www.mysite.com', false);
