mraza · October 7, 2009

hi before i was having problem with PHP version 4.4.9 with header function that i solved by adding a line "AddType x-mapp-php5 .php" now my problem is this when i click submit i get this error :

Warning: Cannot modify header information - headers already sent by (output started at /homepages/21/d295542507/htdocs/includes/registration.php:19) in /homepages/21/d295542507/htdocs/includes/registration.php on line 73

and my line 73 is:

	  else {header('Location: payments.php');}

and this is code between page you can see line 73 where it redirect:

<?php 

if(isset($_POST['sub1'])){

$title = $_POST['title'];
$name = $_POST['name'];
$insurance = $_POST['insurance'];
$address = $_POST['address'];
$phone = $_POST['phone'];

$_SESSION['address'] = $_POST['address'];
$_SESSION['phone'] = $_POST['phone'];
$_SESSION['email'] = $_POST['title'];
$_SESSION['registration'] = $_POST['registration'];
$_SESSION['comments'] = $_POST['comments'];

$error = "";

if (!$title)
$error = $error."<font color=\"red\">Title </font><br />";
if (!$name)
$error = $error."<font color=\"red\">Name</font> <br />";

  else {header('Location: payments.php');}
}elseif(isset($_POST['sub2'])){

$title = $_POST['title'];

$insurance = $_POST['insurance'];
$address = $_POST['address'];
$phone = $_POST['phone'];
$email = $_POST['email'];
$registration = $_POST['registration'];

$_SESSION['address'] = $_POST['address'];
$_SESSION['phone'] = $_POST['phone'];
$_SESSION['email'] = $_POST['title'];
$_SESSION['registration'] = $_POST['registration'];
$_SESSION['comments'] = $_POST['comments'];

$error = "";

if (!$title)
$error = $error. "<font color=\"red\">Title</font> <br />";
if (!$name)
$error = $error. "<font color=\"red\">Name</font> <br />";
if (!$insurance)
$error = $error. "<font color=\"red\">National Insurance Number</font> <br />";

  else {

you can't have any output at all before the header call. judging by how far down in the code it is, im willing to bet something is output before you try to call that

mikesta707 · October 7, 2009

so its working? than whats the problem

mraza · October 7, 2009

its not working on my host server they have PHP 4.4.9 version

PFMaBiSmAd · October 7, 2009

Sadly, a lot of development systems using the xAMP all in one packages are NOT setup properly as development systems where the code you get working on them will work on the majority of actual servers.

Your development system has output_buffering turned on in the master php.ini. I recommend that you turn it off (it is off on your live server) so that code you develop on your localhost has a chance of working on your live server.
