There's no output going to the browser before session_start(). The
top of my script looks like this:
--quote
<?php
error_reporting(E_ALL);
ini_set("display_errors","1");
?>
<?php
/* Should only be debugging from one machine
* Should plan on making this a config variable
*/
if ($_SERVER['REMOTE_ADDR'] == '192.168.1.201')
{
$debug = 1;
}
$html='';
require_once('includes.php');
session_start();
--end quote
After that, there is content that is put into a variable and then run
through a filter before it gets echoed to the browser. There's an
onLoad="" call in the body tag that trips off another request, which
generates content that includes a link, as well as setting a $_SESSION
variable in the process. The problem is that it doesn't appear to
"write" the variable out to the session storage, because subsequent
requests can't see it.
