PHP - Redirect

I'm trying to put together a script that redirects visitors based on their IP, user agent and/or referral url. Basically I want the script to scan these three factors from the visitor, if any of them turn out to match my redirect-requirement it redirects the user. I know the code is horribly coded, I'm incredibly new to the php-scene and consider myself a complete noob. As you can see I want redirected visitors to go to google.com and un-redirected to msn.com(examples). Really thankful for all the help I can get! Right now nothing works, any suggestions?

<?php
 
function redirect($page) {
        Header( "HTTP/1.1 301 Moved Permanently" );
        header('Location: ' . $page);
        exit;
}
 
$referrals=array('pitchingit.org','referral2');
$badAgents = array("useragent1", "useragent2");
$deny = array("78.105.191..*","100.101.103..*");
 
if (in_array($_SERVER['HTTP_REFERER'], $referrals, FALSE)) 
{
        header("Location: http://www.google.com");
} 
else 
{
        header("Location: http://www.msn.com");
}  
 
if(in_array($_SERVER['HTTP_USER_AGENT'],$badAgents)) 
{
        redirect("http://www.google.com/");
        exit();
} 
 
$add=$_SERVER['REMOTE_ADDR'];
foreach ($deny as $ip) {
        if (preg_match("^.$add.*^",$ip)) {
        redirect("http://www.google.com");
        }
}
 
redirect("http://www.msn.com");
 
?>

How can one re-direct a visitor, without using a header re-direct?  I'd like a page to show up, then after about 5 seconds I need the visitor sent to another page.  How can I do this?

Hi,

I'm trying to figure out if I can get a redirect page to work, without needing to use the header("Location: page.php"); command.

I know with asp, there is a response.redirect for redirecting pages, but, with the header, I can only use this, if there is no output before calling the command.

Is there any method that can be used where I can process some code, if output is required, and depending on processing on the page, redirect it to another page, using a command similar to response.redirect?

I have seen the http_redirect, but I can only see this working with clearing buffers etc. I have also a redirect_to("page.php"); command, but I cannot get this to work.

I am using php 5.

Any help would be appreciated.

Thanks.

Hi guys, this is my first post here.

I'm looking for some help with some code for a form submission. It all works fine but if I add in a redirect using the advice found he http://www.computing.net/answers/webdevel/redirection-after-submit-php-form/3580.html. I'm using the following code:
Code: [Select]
<?php

header ('Location: http://www.jwhunterhill.co.uk/return.html');
exit ();

if(isset($_POST['email'])) {
     
    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "xxx@gmail.com";
    $email_subject = "E-mail from JWHunterHill.co.uk";
     
     
    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['comments'])) {
        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']; // not required
    $comments = $_POST['comments']; // required
     
    $error_message = "";
    $email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";
  if(!eregi($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
    $string_exp = "^[a-z .'-]+$";
  if(!eregi($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
  if(!eregi($string_exp,$last_name)) {
    $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
  }
  if(strlen($comments) < 2) {
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }
  if(strlen($error_message) > 0) {
    died($error_message);
  }
    $email_message = "Form details below.\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";
    $email_message .= "Comments: ".clean_string($comments)."\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 -->
 
Thank you for contacting me. I will be in touch with you very soon.
 
<?php
}
?>
As I said the code works fine just if I include the redirect, the form will not send me an e-mail as required. Could you help me out please?

Thanks in advance,

Jonathon

Ok I know I can redirect using:

header( 'Location: URL' ) ;


Now, is there a way to delay this after a short while of displaying or would I have to use Javascript?
