title: How to change this form to redirect
body: <p>I am using this PHP form below - how can I change it to redirect rather than opening a blank page that says "message sent"?</p>
  
  <pre><code>&lt;?php
  
  if(!$_POST) exit;
  
  $email = $_POST['email'];
  
  
  //$error[] = preg_match('/\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i',
  $_POST['email']) ? '' : 'INVALID EMAIL ADDRESS';
  if(!eregi("^[a-z0-9]+([_\\.-][a-z0-9]+)*" ."@"."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a
  z]{2,}"."$",$email )){
  $error.="Invalid email address entered";
  $errors=1;
  }
  if($errors==1) echo $error;
  else{
  $values = array ('name','email','message');
  $required = array('name','email','message');
  
  $your_email = "laurafoley@mac.com";
  $email_subject = "New Message Help Hershey: ".$_POST['subject'];
  $email_content = "new message:\n";
  
  foreach($values as $key =&gt; $value){
    if(in_array($value,$required)){
      if ($key != 'subject' &amp;&amp; $key != 'company') {
        if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS';
  exit; }
      }
      $email_content .= $value.': '.$_POST[$value]."\n";
    }
  }
  
  if(@mail($your_email,$email_subject,$email_content)) {
      echo 'Message sent!'; 
  } else {
      echo 'ERROR!';
  }
  }
  ?&gt;
  </code></pre>
  
  <p>I don't know if it is a matter of just changing the echo 'Message Sent' line or how to change this so that it either redirects to a thank you page or back to the home page</p>
