Session without password?

[argan328]

Hi

I have created a website with a terms of service statement and a checkbox on the index page... users have to agree to the TOS before viewing the contents of the site.  If a user has not agreed to the TOS and tries to link directly into one of the content pages I want them to be redirected to the index page until they click on the checkbox... I don't want to require a password, I just want them to click on the checkbox at each session.  I think I need a session class but am not sure if that would do the job.

 

Can anyone help confirm that a session class alone would accomplish this??

 

Thanks so much!

Sessions or cookies would be fine.

 

<?php

  if(!isset($_SESSION['tos'])) {

  header("location: index.php?notice=tos");
  }

?>

Thx Caesar.  I would expect this code go on every one of the content pages (I know HTML better than PHP at this point)-- but would I set the variable 'tos' in the session class itself or on the index page?

I'm going to try to use this basic session code I found at http://www.weberdev.com/get_example-4175.html

    // Use this in every page you wa! nt to use sessions first
    $sess = new sessions()
     
    // To set a variable

sessions in a nut shell.

 

Only use session_start() at the top of the html of php page, what I mean is don't have a page use session_start() and then try to use an include("page.php"); that also has a session_start() or it will give you a header has already been sent error. Make sure to put the session_start() at the very begining of the script even before any whitespace.

 

Declaring a session variable

 

$_SESSION['tos'] = value;

 

calling a session variable

 

echo $_SESSION['tos'];

 

It's really that simple.
