simple login to use another form on same page

mccoding

The first form displayed is the login form. When they enter the right login info I want it to go to another form on the same page. This will keep people from using the second form without a login. However, I want people to be continue using that form until they close the browser. How do I do that.

<?php 
if (($_SESSION['loggedin'] != "yay")) { ?>

This displays the login form only
I set the session loggedin to yay after they successfully filled out the login form.
I also used session_start();

<?php } else {?>

wont display the second form until login.
But when I submit the second form I get put back on the login form. How should I use session variables in this scenario?

Tough to tell for sure without seeing more of the code, but you need to be sure that you do a session_start() before checking any $_SESSION values.

hi!
I think you should do another way.

Have a test at top of page
and if they are not logged in, send them to a login.php

if( !$loggedin ){

echo 'you have to login first. ';
echo '<a href='login.php'>login</a>';
exit();

}

// rest of your 'FORM 2' page

We often make the mistake of putting it all in same php page
.. or at least too much features in one page
This will make coding problematic, with numerous if(this and that) nested testings.

When I look at some experienced coders php pages
it sometimes make me surprised how little and simple code they need.

I have seen horrible examples, when complete website CMS was only in one 'index.php'.
Think I never have seen more messed up, uncomprehendable and complicated php programming 😃 😃

I prefer use many pages. With little code in each.
Using links and/or includes to put it all together.

generally I agree, but this is a minor project. This site helped me, although I am not using a database.

yes

that site is using several small scripts

In this tutorial create 3 files
1. main_login.php
2. checklogin.php
3. login_success.php

... and each of these pages are not very complicated
Each of them do just about one thing

Ya thats how I was trained on doing things, but for this small of a project I would rather look at one page then tab through several
I put this in front of my first form:
session_start();
if (!session_is_registered(loggedin)) {

Then an else in front of the other. Works great!

Next question: since I am not worried too much about security, I made a login and password file. I am trying to compare strings from the login page to variables in that file. It works good if they enter 1 string right, but it needs to only work if the combo is correct.

	$username=$_POST['username'];
	$password=$_POST['password'];
	if (($username != $adminlogin) && ($password != $adminpassword))

again I fail.
