My first PHP form validation

[IanMartins]

I'd greatly appreciate any advise on how to fix this short email validation script. At the bottom of the code, I've included the script that successfully sends me an email when I enter the correct email-address. When I insert it into the above script, the page that I'm sending it from goes blank when I hit the submit button, and no email is sent... nor do any of the echo messages that I've inserted pop up.

Should I perhaps be using something other than FILTER_SANITIZE_EMAIL and FILTER_VALIDATE_EMAIL?

Thank you.

<?php
        if(isset($_POST['submitEmail'])) {
                if (!spamcheck($_REQUEST['submitEmail'])) {
                        echo "Invalid input";
                } else { //EVERYTHING INSIDE THIS TAG HAS TESTED OK ON ITS OWN
                        $email_to = "[e-mail]";
                        $email_from = $_REQUEST['email'];
                        $name_from = $_REQUEST['name'];
                        $subject = "This is a subject";
                        $message = $_REQUEST['message'];
                        $headers = "From: $name_from <$email_from>\n" .
                        "Return-Path: $email_from\n" .
                        "MIME-Version: 1.0\n" .
                        "Content-Type: Content-type: text/html; charset=iso-8859-1\n";
                        mail($email_to, $subject, $message, $headers);
                        echo "<script>alert('Your message has been successfully delivered.');</script>";
                } //END SCRIPT THAT HAS TESTED OK ON ITS OWN
        }

    function spamCheck($field) {
            $field = filter_var($field, FILTER_SANITIZE_EMAIL);
            if (filter_var($field, FILTER_VALIDATE_EMAIL)) {
                    echo "Spamcheck ok!";
                    return true;
            } else {
                    echo "Spamcheck failed!";
                    return false;
            }
    }
?>

//THIS PART IS CONFIRMED AS WORKING ON ITS OWN, I RECIEVE MAIL USING IT
<?php
	if($_POST['submitEmail']) {
		$email_to = "[e-mail]";
		$email_from = $_REQUEST['email'];
		$name_from = $_REQUEST['name'];
		$subject = "This is a subject";
		$message = $_REQUEST['message'];
		$headers = "From: $name_from <$email_from>\n" . 
		"Return-Path: $email_from\n" . 
		"MIME-Version: 1.0\n" . 
		"Content-Type: Content-type: text/html; charset=iso-8859-1\n"; 
		mail($email_to, $subject, $message, $headers);
		echo "<script>alert('Your message has been successfully delivered.');</script>";
	}
?>

MOD EDIT: No need to link to pastebin... just include the PHP code in your post (along with the [noparse]

[/noparse] bbcode tags).
