all new php code now sends the header already sentwarning

#1 (**permalink**) 10-01-2008, 01:49 PM

I have had none of these 'headers already sent....' problems creating php forms
in the past with dreamweaver cs3 (on leopard). Now, every single php form
generated using dreamweaver returns this warning - without fail. I copied the
EXACT code from a working login form into a new page.....the new page, using
the same include file is now returning the warning: I am pasting the code that
works, and below that, the code that does not work. Even Developer Toolkit, on
the rare occasion it doesn't cause DW to crash, seems to be inserting code that
does not work properly - same goes for the insert > data objects.

I've attached the code from both pages - page that works at the top, page that
doesn't work at the bottom:

<?php require_once('Connections/ContactForm.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "",
$theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

$theValue = function_exists("mysql_real_escape_string") ?
mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
