[SOLVED] session_start() header error

pcw · March 16, 2009

Hi, I keep getting the following error:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/moveitho/public_html/sitebuilder/templates/common/header.php:46) in /home/moveitho/public_html/sitebuilder/data/library/form_validation.php on line 5

This is the code for form_validation.php

<?php

function form_validation() {
             
session_start(); 
if(isset($_POST['submit']))
{

$veritxt = $_POST['veritxt'];
$username = $_POST['username'];
$password1 = $_POST['password1'];
$password2 = $_POST['password2'];
$email = $_POST['email'];
$firstname = $_POST['firstname'];
$surname = $_POST['surname'];
$street = $_POST['street'];
$city = $_POST['city'];
$county = $_POST['county'];
$postcode = $_POST['postcode'];
$country = $_POST['country'];
$telephone = $_POST['telephone'];
$mobile = $_POST['mobile'];
$gender = $_POST['gender'];

if ($_POST['veritxt'] != $_SESSION['veritxt'] OR $_SESSION['veritxt']=='')
{
print "Image verification unsuccessful.";
}
elseif ($username == '') 
{
print "Please enter a username";
}
elseif ($password1 == '')
{
print "Please enter your password";
}
elseif ($password1 != $password2)
{
print "The passwords you supplied do not match";
}
elseif (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email))
{
print "Please enter a valid email address";
}
elseif ($firstname == '')
{
print "Please enter your first name";
}
elseif ($surname == '')
{
print "Please enter your last name";
}
elseif ($street == '')
{
print "Please enter your street address";
}
elseif ($city == '')
{
print "Please enter your town/city";
}
elseif ($county == '')
{
print "Please enter your county";
}
elseif ($postcode == '')
{
print "Please enter your last name";
}
elseif ($country == '')
{
print "Please enter your country";
}
elseif ($surname == '')
{
print "Please enter your last name";
}
elseif ($telephone == '')
{
print "Please enter your telephone number";
}
elseif ($mobile == '')
{
print "Please enter your mobile number";
}
elseif ($gender == '')
{
print "Please enter your gender";
}
else { 
pin();
email_reg();
add_user();
}
}
};
?>

and this is the code for header.php

<?php 
function pageheader() {
print '
<html>
<head>
<style type="text/css">
<!--
.style1 {
color: #FFFFFF;
font-family: Arial, Helvetica, sans-serif;
font-size: 24px;
}
.style2 {
color: #FFFFFF;
font-family: Arial, Helvetica, sans-serif;
}
.style3 {
color: #FFFFFF;
font-family: Arial, Helvetica, sans-serif;
font-size: 14px;
}
{
.style4 {color: #FFFFFF}
.style6 {color: #FFFFFF; font-weight: bold; }
.style7 {color: #FFFFCC}
}

a:link {
color: #FFFF99;
}


-->
</style>

</head>
<body bgcolor="#14285f">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
   <tr bgcolor="02021e">
    <td height="58" nowrap="nowrap" colspan="3" id="logo" valign="bottom"><div align="center" class="style1">SiteBuilder Version 2.0 </div></td>
  </tr>
  <tr bgcolor="02021E">
    <td height="57" nowrap="nowrap" colspan="3" id="tagline" valign="top"><div align="center" class="style2">Build your own membership site </div></td>
  </tr>
</table>
<br>';
};
?>

I cant figure out why I keep getting this error. How do I fix this?

Thanks

Put session_start() at the top of your page.

If it doesn't validate you can always set a flag.
