Contact form PHP shows blank - php

Question

I took a standard form that I always use which included a comments are. For this website I don't need comments so I only left email and url in it. When I remove the everything related to comments in my PHP file it shows a blank page, not even an error.
Here's the code:
<?php
if(isset($_POST['email'])) {
// CHANGE THE TWO LINES BELOW
$email_to = "email#email.com";
$email_subject = "NEW CONTACT";
function died($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['email']) ||
!isset($_POST['url'])) || {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$email_from = $_POST['email']; // required
$url = $_POST['url']; // not required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
if(strlen($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);
}
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "url: ".clean_string($url)."\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);
?>
<!-- place your own success html below -->
Success
<?php
}
die();
?>

Answer 1

You have extra || in your if condition. Remove that and it should work.
if(!isset($_POST['email']) ||
!isset($_POST['url'])) || {
^^^^
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
