Question

I followed this guide as an attempt to write a login script for my hobby webpage.

Problem is when I want to incorporate it into my page, problems occur.

I’m trying to make an admin panel.

In the top of the frame I want the login form to be

When I log in, I’d like the Login form area to change into Logout fields.

My problem is that all cookie-related calls has to be done before the HTML code starts…

So:

• When you log in: content of the page should be displayed ( a simple include ).
• When you log in: login area changes into logout area, thus hiding the login fields and displaying name of user logged in…
• and when logging out: content and logout should disappear and show login fields again.

How can this be done (give examples like pseudo code)?

PS. Im not a PHP nerd, still learning.

Answer 1

You could write your login Data into your current session.

$_SESSION["username"] = $user;

But don’t forget to call session_start() at the top of your code.

After that you check whether "$_SESSION["username"]" is set with your data. If so, you can change your content to whatever you like.

Example:

if (isset($_SESSION['username']) && loginSuccessful()) {
    include("AdminMenue.php");
}

loginSuccessful() should be a method that checks whether your Login Data can be found in your database.
