Sessions are killing me

[kevinak]

Ok, I've searched and searched but I can't figure out how to make sessions work for what I need

 

We have two pages.

1. Confirm page

2. Reward Page

 

I tried setting a session on the Confirm page with this code.

<?php
$_SESSION['OMG']= 'on';
session_start();
?>

 

I think that's right. Now I need to call that session and check if it is set, if it is then I want the user to get the reward on the rewards page. If it's not I want an error to come up.

Then I need the session to destory itself or reset to nothing so they can't refresh or simply change the url to get a different reward without going through the confirm page.

 

In other words. I want them to first go to the confirm page at all times. No way around it.

 

<?php
session_name();
session_start();
?>

 

This is what I used to call the sessions on the Rewards Page. (I'm very new to sessions)

 

Then my if is simply this

if (!isset($_SESSION['OMG'])) {
//error here
}
else {
//reward here
}

 

Thank you for reading and for any responses

session_start() has to be before you do pretty much anything with sessions..

 

session_start();
$_SESSION['foo'] = 'bar';

 

then, on a later page you call it after session_start();

 

session_start();
echo $_SESSION['foo'];

 

as for your implementation, hopefully you can derive it from this explanation of sessions.

confirm page

<?php
session_start(); //session_start() comes first
$_SESSION['confirmed'] = 'yeah baby';
?>

 

reward page

<?php
session_start(); //session_start() comes first here too
if(isset($_SESSION['confirmed'])){
    echo 'yeah baby. here is your award';
} else{
    echo 'nah, youre cheating';
}
?>

 

EDIT: genericnumber1 beat me to it, but i'm posting this anyway

You guys are the best seriously

Very fast and super knowledgeable.

Thank you so much.

I'm going to put these up right away

 

Oh and if any of you see this. How would I then destory the session?

 

Do I use the session_destroy() function?

Here ya go!

 

<?php
session_start();
$_SESSION = array();
session_destroy();
?>
