PHP Mail form issue after refresh [duplicate] - php

Question

I have read all your posts about inserting headers into a php form file in order to redirect the user to another URL AFTER the form is submitted - but I can't figure out how to do it. Below is my code. Can you show me where to put the header/redirect so that the information gets e-mailed and then the user goes to another html page?
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "pecraig#moneymovers.com";
$email_subject = "Mailing List Form";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you
submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['company']) ||
!isset($_POST['street']) ||
!isset($_POST['city']) ||
!isset($_POST['state']) ||
!isset($_POST['zip'])) {
died('We are sorry, but there appears to be a problem with the form you
submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // required
$company = $_POST['company']; // required
$street = $_POST['street']; // required
$city = $_POST['city']; // required
$state = $_POST['state']; // required
$zip = $_POST['zip']; // required
$error_message = "";
$string_exp = "/^[A-Za-z0-9 .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$last_name)) {
$error_message .= 'The Last Name you entered does not appear to be valid.<br />';
}
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$company)) {
$error_message .= 'The Company you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$street)) {
$error_message .= 'The Street you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$city)) {
$error_message .= 'The City you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$state)) {
$error_message .= 'The State you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$zip)) {
$error_message .= 'The Zip Code you entered does not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Response from Mailing List Page. Please enter in database.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Last Name: ".clean_string($last_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Company: ".clean_string($company)."\n";
$email_message .= "Street: ".clean_string($street)."\n";
$email_message .= "City: ".clean_string($city)."\n";
$email_message .= "State: ".clean_string($state)."\n";
$email_message .= "Zip: ".clean_string($zip)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
#mail($email_to, $email_subject, $email_message, $headers);
?>
<!-- include your own success html here -->
Thanks for subscribing to our mailing list
<?php
}
?>

Answer 1

Right after #mail($email_to, $email_subject, $email_message, $headers);
header('Location: nextpage.php');
Note that you will never see 'Thanks for subscribing to our mailing list'
That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!

Answer 2

First give your input type submit a name, like this name='submitform'.
and then put this in your php file
if (isset($_POST['submitform']))
{
?>
<script type="text/javascript">
window.location = "http://www.google.com/";
</script>
<?php
}
Don't forget to change the url to yours.

Answer 3

If your redirect is in PHP, nothing should be echoed to the user before the redirect instruction.
See header for more info.
Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP
Otherwise, you can use Javascript to redirect the user.
Just use
window.location = "http://www.google.com/"

Answer 4

You can include your header function wherever you like, as long as NO html and/or text has been printed to standard out.
For more information and usage: http://php.net/manual/en/function.header.php
I see in your code that you echo() out some text in case of error or success. Don't do that: you can't. You can only redirect OR show the text. If you show the text you'll then fail to redirect.

Answer 5

Whenever you want to redirect, send the headers:
header("Location: http://www.example.com/");
Remember you cant send data to the client before that, though.

Answer 6

Once had this issue, thought it reasonable to share how I resolved it;
I think the way to do that in php is to use the header function as:
header ("Location: exampleFile.php");
You could just enclose that header file in an if statement so that it redirects only when a certain condition is met, as in:
if (isset($_POST['submit'])){ header("Location: exampleFile.php") }
Hope that helps.
