[Resolvido] Erro ao enviar informações por formulário com html e php

Bom dia,

Estou com uma página retornando erro e não consigo corrigir. Sou iniciante em php e até o momento, a dificuldade persiste. Ao enviar a mensagem pelo formulário de contato a página não atualiza e retorna o seguinte erro:

Notice: Undefined variable: message in /storage/ssd3/973/8336973/public_html/inc/sendEmail.php on line 31

Notice: Undefined variable: error in /storage/ssd3/973/8336973/public_html/inc/sendEmail.php on line 47

OK

Este é o código do fomulário:

<!-- form -->

 <form name="contactForm" id="contactForm" method="post" action="sendEmail.php">
 <fieldset>

 <div class="form-field">
 <input name="contactName" type="text" id="contactName" placeholder="Name" value="" minlength="2" required="">
 </div>
 <div class="form-field">
 <input name="contactEmail" type="email" id="contactEmail" placeholder="Email" value="" required="">
 </div>
 <div class="form-field">
 <input name="contactSubject" type="text" id="contactSubject" placeholder="Subject" value="">
 </div>
 <div class="form-field">
 <textarea name="contactMessage" id="contactMessage" placeholder="Message" rows="10" cols="50" required=""></textarea>
 </div>
 <div class="form-field">
 <button class="submitform">Enviar</button>
 <div id="submit-loader">
 <div class="text-loader">Sending...</div>
 <div class="s-loader">
 <div class="bounce1"></div>
 <div class="bounce2"></div>
 <div class="bounce3"></div>
 </div>
 </div>
 </div>

 </fieldset>
 </form> <!-- Form End -->

	 

	Este é o Php:

// Replace this with your own email address

$siteOwnersEmail = 'user@website.com';

if($_POST) {

 $name = trim(stripslashes($_POST['contactName']));
 $email = trim(stripslashes($_POST['contactEmail']));
 $subject = trim(stripslashes($_POST['contactSubject']));
 $contact_message = trim(stripslashes($_POST['contactMessage']));

 // Check Name
	if (strlen($name) < 2) {
 $error['name'] = "Please enter your name.";
	}
	// Check Email
	if (!preg_match('/^[a-z0-9&\'\.\-_\+]+@[a-z0-9\-]+\.([a-z0-9\-]+\.)*+[a-z]{2}/is', $email)) {
 $error['email'] = "Please enter a valid email address.";
	}
	// Check Message
	if (strlen($contact_message) < 15) {
 $error['message'] = "Please enter your message. It should have at least 15 characters.";
	}
 // Subject
	if ($subject == '') { $subject = "Contact Form Submission"; }

 // Set Message
 $message .= "Email from: " . $name . "<br />";
	$message .= "Email address: " . $email . "<br />";
 $message .= "Message: <br />";
 $message .= $contact_message;
 $message .= "<br /> ----- <br /> This email was sent from your site's contact form. <br />";

 // Set From: header
 $from = $name . " <" . $email . ">";

 // Email Headers
	$headers = "From: " . $from . "\r\n";
	$headers .= "Reply-To: ". $email . "\r\n";
 $headers .= "MIME-Version: 1.0\r\n";
	$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

 if (!$error) {

 ini_set("sendmail_from", $siteOwnersEmail); // for windows server
 $mail = mail($siteOwnersEmail, $subject, $message, $headers);

 if ($mail) { echo "OK"; }
 else { echo "Something went wrong. Please try again."; }

	} # end if - no validation error

	else {

 $response = (isset($error['name'])) ? $error['name'] . "<br /> \n" : null;
 $response .= (isset($error['email'])) ? $error['email'] . "<br /> \n" : null;
 $response .= (isset($error['message'])) ? $error['message'] . "<br />" : null;

 echo $response;

	} # end if - there was a validation error

}

?>

	 

	Poderiam me ajudar??

	 

	O envio funciona, porém apresenta a mensagem de erro e não atualiza a página.

	 

	Grato.
