passing variables

autocolismo

<html><head><title></title></head><body>
<a href="?action=nots">nots</a> 
- <a href="?action=arch">arch</a> - 
<a href="?action=pro">pro</a><br>

<?php	
  if ((!isset($action)) ) {
  include "firstpage.php";
 }else{
  echo $action;
  include $action . ".php";
  }
  ?>
</body></html>

the code above workx fine in my personal web server (apache + php) but in a hosting server doesn't, when i click in "nots" it should open the same page with the variable $action defined as "nots", but it doesn't happen, why is that????

thanks in advance 😕

Hi,

most likely this is due to the settings of register globals in the php.ini.

If you receive your data via get method (or appended to the url), use
$_GET['action'] instead of $action
(or in older versions $HTTP_GET_VARS['action'])

The same applies to $POST, $COOKIES, $_FILES etc.

Hope this helps,

_SuperString

you may need to use super globals, try this:

// use
$_GET['action'];
// dont use
$action

Not sure if you want to do this but you could use the following code to get around your problem.

if (!empty($_GET))
{
    extract($_GET);
} else if (!empty($HTTP_GET_VARS))
{
    extract($HTTP_GET_VARS);
}

You use the same thing for post. I got this from here:

php.net

Towards the bottom of the page.
