[SOLVED] Simple Question About Sessions

[tamumech]

Hi,

 

I am trying to implement a token identifier with a session.  Can anyone explain to me how store it in the session data and use in get or post requests?

 

Thanks

To store a value in a session use...

 

<?php

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

?>

 

then.. to retrieve it...

 

<?php

  session_start();
  $var = $_SESSION['var'];
  echo $var;

?>

 

Pretty straight forward stuff.

I understand how to store session data, but how do I use it in GET or POST requests?

 

I am actually trying to store something in the URL, and something in a session cookie.  Is there a way to do that without a form appearing on the page?

 

Thanks

<?php

  session_start();
  $_SESSION['var'] = 'foo';
  echo "<a href=\"link.php?var={$_SESSION['var']}\">link</a>";

?>

What do you mean?

For example you want to link someone to a page, that needs their userID to display user information about them?

 

<?php
session_start();
$userID = $_SESSION['userID'];
echo '<a href="information.php?userID='.$userID.'">View Your Info</a>';
?>

Alright, do I have to do that on every hyper link on the page.  Good times.

 

Thanks fellas.
