hello!, i'm practicing with php sending mails, manipulating databases, and everything is going right, but when i try to redirect the browser to a page with header("Location: mysite.html"); after it ends the transactions, the navigator shows an error and don't redirects the browser, the error is:

QUOTE

Warning: Cannot modify header information - headers already sent by (output started at /home/epox/public_html/contacto.php:9) in /home/epox/public_html/contacto.php on line 13

if someone knows how to correct the error i will be so gratefuly.

You MUST use quote tags whenever you are copying.

That error normally appears if you try to set a header after it has already been sent. Headers must be set before the script outputs anything to the browser or any action is taken like that. If you need to force another page, try using some simple javascript.

The code header("Location: mysite.html"); MUST be put at the very beginning of your code...before headers are sent. That's basically all I can tell you without looking at the code.

You can also try my script: http://www.trap17.com/forums/email-script-...php-t20516.html

helloo!, here goes the code:

this is the php code:

CODE

<?php
$dbh=mysql_connect ("localhost", "epox", "******") or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ("epox_tribusuburbanas");
$nombre=$_GET['nombre'];
$mail=$_GET['mail'];
$movil=$_GET['movil'];
$fijo=$_GET['fijo'];
mysql_query("insert into agenda values ('$nombre','$mail','$movil','$fijo')",$dbh);
header("agenda.htm");
?>

and here the htm:

CODE

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Agenda</title>
<style type="text/css">
body{
margin-top: 20px;
text-align: center;
background-color: #666;}

#container{
background-color: #3399FF;
border: 1px solid #fff;
margin-right: auto;
margin-left: auto;
padding: 0px 10px 10px 0px;

#header h3{

font-weight: normal;}

#form{
padding-left: 10px;
padding-top: 10px;
color: #CCCCCC;
text-align: left;}

</style>

</head>

<body>
<div id="container">
<div id="header"><h3>Agenda</h3></div>
<div id="form">
<form name="agenda" action="agenda.php">
<input type="text" name="nombre"> Nombre<br>

I do not mysql much but don't you have to close the connection with the database? Try putting mysql_close(); before the header command.

Also, I've just noticed, that that's not how you redirect someone with php. It should be:

CODE

header("location:agenda.htm");

Try these small changes and then see if it works

[...]

Make sure you have NO whitespace before your <?php tag, as that whitespace will cause PHP to start outputting to the browser, which in turn causes the default headers to be sent...

Also, you should specify the full URL to the file to redirect to..

This quote is from PHP.net on the subject:

QUOTE(PHP.Net)

Note: HTTP/1.1 requires an absolute URI as argument to Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative one yourself:

CODE

<?php
header("Location: http://" . $_SERVER['HTTP_HOST']
. dirname($_SERVER['PHP_SELF'])
. "/" . $relative_url);
?>

I hope that helps!!
