Can't start session

[Anon]

When I add session_start(); to the beginning of my php code, I get the following error.

Warning: Cannot send session cookie - headers already sent by (output started at /home/site/ecommerce/index.php:1) in /home/site/ecommerce/index.php on line 1

Warning: Cannot send session cache limiter - headers already sent by (output started at /home/site/ecommerce/index.php:1) in /home/site/ecommerce/index.php on line 1

You need to place the session_start at the very top of the page. Before any other code is sent to the browser.

Ok. Thanks. That worked. I had some html before my php code.

I can't get session_register() to work.

I'm using the following:

page1.php

<?
session_start();
session_register("asdf");
$asdf = "It works.";

echo "<a href=\"page2.php\">Go to next page</a>";

?>

page2.php

<?
session_start();
if(session_is_registered("asdf"))
{
$qwerty = "Session is registered.";
} else {
$qwerty = "Session is not registered.";
}

echo "$qwerty";

?>

Page2.php returns:
Session is not registered.

just a wild guess...
but you define the variable before it is set. Try this

$asdf = "test";
session_register(asdf);

that should work...
