I have developed a contact us page and also PHP code that works perfect. Know the only problem is that after submitting the form it shows only "Message sent" on a new page. I want that after submitting the form page will redirect back to home page. It is only one page "Landing Page". Here is the PHP code.
    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 )){
    	$error.="Invalid email address entered";
    if($errors==1) echo $error;
    	$values = array ('name','email','message','phone');
    	$required = array('name','email','message','phone');
    	$your_email = "todd@toddandersonhomes.com";
    	$email_subject = "Free Credit Report: ".$_POST['subject'];
    	$email_content = "Following is the free credit report detail from client:\n";
    	foreach($values as $key => $value){
    		if ($key != 'subject' && $key != 'company') {
    		  if( empty($_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!';
