emulate register_globals On

mac100

Hi I'm a newbie at this site, and with PHP...

I'm trying to get a PHP script to function, that was originally written to use 'register_globals = on'

My server has 'register_globals = off'
So as a temporary measure, to emulate register_globals On,
I have pasted the code below into the header of my pages.
This script was recommended by: uk.php.net... at...

http://uk.php.net/manual/en/faq.misc.php#faq.misc.registerglobals

Example 62-1. Emulating Register Globals

This will emulate register_globals On.

<?php
// Emulate register_globals on
if (!ini_get('register_globals')) {
$superglobals = array($SERVER, $ENV,
$FILES, $COOKIE, $POST, $GET);
if (isset($SESSION)) {
array_unshift($superglobals, $SESSION);
}
foreach ($superglobals as $superglobal) {
extract($superglobal, EXTR_SKIP);
}
}
?>

My original script was using 'sessions' to allow me to access the value of a 'varable value' from page to page,

But the above script, still wont let me access the 'session variable'

the $_SESSION array will only exist after you have called [man]session_start[/man]. are you calling this code before [man]session_start[/man]?

Hi, devinemke,
Thanks for the reply...

The first page has the following original script:

<?php #session_start();

if($font_family != null)
{
  if( ! session_is_registered("session_font") )
  { session_register("session_font"); }
  $session_font = $font_family;
  header("Location:prefs2.php?".SID);
  exit();
}

<html><head><title>Session preferences</title></head>
<body>
<h3>Select Your Preferred Font Family</h3>
<form action="<?php echo($PHP_SELF); ?>" method="post">
<input type="radio" name="font_family" value="serif">Serif
<input type="radio" name="font_family" value="sans-serif">Sans-Serif
<input type="radio" name="font_family" value="monospace">Monospace
<input type="radio" name="font_family" value="cursive">Cursive
<input type="radio" name="font_family" value="fantasy">Fantasy
<br/><br/>
<input type="submit" value="Submit">
</form>
</body></html>

I added the following script before the above original code...

so the current page now looks like this...

#session_start();

if($font_family != null)
{
  if( ! session_is_registered("session_font") )
  { session_register("session_font"); }
  $session_font = $font_family;
  header("Location:prefs2.php?".SID);
  exit();
}
