I have a database in mysql which contains of four tables (Student, Units, Offering and Enrols_in) and i want to create an enrolment page where students can enrol in units which will be offered in each semester. Student names will be entered in the database and they will use their given password and username to log into the system. When they are loged in, they will have to enrol themselves in the units which are offered and the units which they are enroled in will be displayed in their student profile. The part I'm confused is the enrol button and on how many page will I have.

Can you clarify your question?

Well you say you are confused in enrol button but show nothing, also the number of pages depends on how you design your system(site). That means if certain things you will separate to each page or combine some that feet into certain category and group them by categories

Without showing your code, it is very difficult to advise/help you.

    session_start();

    //retrieve the user name
    $user = $_POST['txtUser']; 
    //retrieve the password
    $pass = $_POST['txtPass'];

    //verify email and password against the database to authenticate the user
        $servername = "localhost";
        $username = "root";
        $password = "";
        $dbname = "enrolment";

    //Create connection
    $conn = mysqli_connect("localhost","root","","enrolment") or die();

    //check the connection
    if(mysqli_connect_error())
    {
        echo "Connection to database failed: " . mysqli_connect_error();
    }
        echo "Connection Successful";

//mysqli_select_dbname('enrolment');
$sql = "SELECT * FROM student WHERE Username = '$user' AND Pass_word = '$pass'";
$result = mysqli_query($conn,$sql);

//Assuming that username and password exist in the database, store the username in a session
if (mysqli_num_rows($result) > 0) {
 $row = mysqli_fetch_array($result);

        $_SESSION["fname"] = $row["FirstName"];
        $_SESSION["lname"] = $row["LastName"];
        $_SESSION["myUser"] = $row["Username"];

    mysqli_close($conn);
    header('location:profile.php');

I don't see enrol button here. Also state exactly what's giving you problem in which line so that it will be a bit easier for us to help you, as to this question I still don't see the part you say you have a problem with "enrol button" or maybe your question is how to create the enrol button?

Please clarify your question.
