My script is:
<html>
<body>
<?php
session_start();
printf("<P> loggin on as ");
printf ("<P>user name: ");
printf ($HTTP_POST_VARS['User']);
printf ("<P>Password: ");printf ($HTTP_POST_VARS['Password']);
printf ("<P>");
/* Connecting, selecting database */
$link = mysql_pconnect("localhost", $HTTP_POST_VARS['User'],
$HTTP_POST_VARS['Password'])
or die("Could not connect");
print "Connected successfully<P>";
printf ("<BR>");
print "Setting Global variables<BR>";
$_SESSION_VARS["dbauser"]=($HTTP_POST_VARS['User']);
$_SESSION_VARS["dbapassword"]=($HTTP_POST_VARS['Password']);
printf ($_SESSION_VARS["dbauser"]);
printf ("<BR>");
printf ($_SESSION_VARS["dbapassword"],"<BR>");
?>
<P>
</body>
</html>
The errors I get are:
Warning: Cannot send session cookie - headers already sent by (output
started at c:\usr\www\my-domain\databaselogin.php:3) in
c:\usr\www\my-domain\databaselogin.php on line 4
Warning: Cannot send session cache limiter - headers already sent (output
started at c:\usr\www\my-domain\databaselogin.php:3) in
c:\usr\www\my-domain\databaselogin.php on line 4
loggin on as
user name: stampuser
Password: vantwest
Connected successfully
Obviously I have something not configured correctly, or I am calling the
function in the wrong place. Any advice on how to overcome this would be
very useful.
