how do i redirect after form is submitted?

how do i make the user go to a new page after the registration form is submitted? here is my code and once they fill out this form i want them to go to a new page

if ($result){
echo "go to new page";
}
else{
echo "aww man no biggie";
}

?>

<form action="new.php" method="post">
<p>First Name: <input type="text" name="firstname" size="15" maxlength="20" value=""/></p>
<p>Last Name: <input type="text" name="lastname" size="15" maxlength="20" value=""/></p>
<p>Email: <input type="text" name="email" size="15" maxlength="20" value=""/></p>
<p>Password: <input type="text" name="pass" size="15" maxlength="20" value=""/></p>
<p><input type="submit" name="submit" value="register"/></p>
<p><input type="hidden" name="submitted" value="TRUE"/></p>
</form>

Code (markup):

 

if ($result){
header("Location:newpage.php");
}
else{
echo "aww man no biggie";
}

PHP:

 

i tried that that then the page just redirected before it even loaded, you coudlnt even fill out the form and it sent you to the new page

 

nevermind i just put my entire php code in an if statement so it didnt run as soon as th erpage laoded, and your script worked! thanks man a ton rep added!

 

you could also use a meta tag to redirect
