Sessions and headers

Anon

I'm trying to use sessions using session_start(); everything seems to work okay, except I'm also using some "hidden" pages to do database updates and build arrays, and then I'm using Header("Location: mypage.php?".sid); to send it on to the next page. Problem is I keep getting random did not return a complete set of headers errors. It has happened on all pages, but not all the time. A simple refresh of the browser and it continues on it's merry way. This is driving me nuts.. any ideas?

Make sure that you do not have any whitespace before the <? tag and after the ?> tag and also make sure that you are not sending anything to the browser before calling header(); ie. print, echo - If that doesnt help post your code.

cheers,

Tried the whitespace thing. Makes no difference.

The first page is an html page that has this at the top;

<?PHP
session_start();
?>

then is all html with a form to login. Passes the userid and password to this page.

<?php
Session_start();
require 'isis_dbcon.php';
$sql = "SELECT *
FROM ISIS_TUSER WHERE userid='$userid' AND userpassword='$password'";
$sql_result = mssql_query($sql,$connection)
or die("Couldn't execute query.");
if (@mssql_num_rows($sql_result) != 0){
$row = mssql_fetch_array($sql_result);
$slxid = $row["USERSLXID"];
$greeting = ' ';
$venid = $row["VENID"];
$userid = $row["USERID"];
session_register("venid");
session_register("userid");
session_register("verified_user");
session_register("slxid");
session_register("greeting");
} else {
$verified_user = 'You have entered an invalid password or username. Please try again';
session_register("verified_user");
session_unregister("slxid");
session_unregister("greeting");
}
require 'isis_dbclo.php';
Header("Location: isis_main.php?".sid);
?>

the 2 require calls are just database connection and closure. nospaces, 2 lines each (this is not it however, even with this information directly in the page I have this problem)

isis_main.php is;

<?
session_start();
require 'header.php';
?>
<table>
<td width="26%">
(continue html here)

header.php contains the following;

<?php
Session_start();
$today = date("F d, Y");
if (isset ($greeting)){
require 'isis_dbcon.php';
$sql = "SELECT *
FROM contact WHERE CONTACTID='$slxid'";
$sql_result = mssql_query($sql,$connection)
or die("Couldn't execute query.");
$row = mssql_fetch_array($sql_result);
$lname = $row["LASTNAME"];
$fname = $row["FIRSTNAME"];
$greeting = "$fname";
session_register("greeting");
}
echo "

<body background='images/background.gif' topmargin='0' leftmargin='10'>
<table border='0' cellpadding='0' cellspacing='0' bordercolor='#111111' width='100%'

</tr>
</table>
</td>
<td width='33%' background='images/milieu.gif'> </td>
<td width='34%' background='images/milieu.gif'>
<table border='0' cellpadding='0' cellspacing='0' style='border-collapse: collapse'

ahh..

Try assigning the session id manually.

$sid = session_id();

header("location:mypage.php?".$sid);

that should solve your problem.. your code above should have produced a parse error.. not sure why it didnt.
