Session variable problems

@aj_nscApr 09.2009 — #register_globals does not need to be enabled to use $_SESSION variables. Also, there's no need to use session_register and $HTTP_SESSION_VARS unless your PHP version is old.

Try this:

1st HTML Page"

[code=php]
 <?php
 session_start();
 $_SESSION['test_var'] = "Testing";
 ?>
 <!-- DOCTYPE, HTML, and CONTENT go here -->
 [/code]

[code=php]
 <?php
 session_start();
 ?>
 <!-- DOCTYPE, HTML, and CONTENT go here -->
 <?php
 echo $_SESSION['test_var'];
 ?>
 [/code]

First simple rule of sessions is that session_start() must be declared on each page that uses any session variable AND session_start() must be executed before anything is sent to the browser:

This is right:

<i>
 </i>&lt;?php
 session_start();
 ?&gt;
 &lt;!-- DOCTYPE, HTML, and CONTENT go here --&gt;

These are wrong:

[code=php]
  <?php session_start(); ?>
 <!-- DOCTYPE, HTML, and CONTENT go here -->
 [/code]

[code=php]
 <!-- DOCTYPE, HTML, and CONTENT go here -->
 <?php session_start(); ?>
 [/code]

Good luck and remember that php.net is your friend (session on php.net)
