Php form validation error after pressing the send button

[NeoNoe89]

Hi guys I'm very new to php and would like to ask you if you could help me to troubleshoot an error I'm getting when submitting an HTML form with the php validation code.

 

The error I'm getting is:

--------------

 

PHP Notice: Undefined variable: telephone in D:\CustomerData\webspaces\webspace_00117117\wwwroot\process.php on line 65
PHP Notice: Undefined variable: enquiry in D:\CustomerData\webspaces\webspace_00117117\wwwroot\process.php on line 66
PHP Notice: Undefined index: HTTP_X_REQUESTED_WITH in D:\CustomerData\webspaces\webspace_00117117\wwwroot\process.php on line 75

 

--------------

 

And the source code is:

--------------

<?php
if( isset($_POST) ){


//form validation vars
$formok = true;
$errors = array();


//sumbission data
$ipaddress = $_SERVER['REMOTE_ADDR'];
$date = date('d/m/Y');
$time = date('H:i:s');




//form data
$name = $_POST['name'];
$company = $_POST['company'];
$phone = $_POST['phone'];
$email = $_POST['email'];
$message = $_POST['message'];
$electives = htmlspecialchars(implode(', ', $_POST['electives']));  
$hear = $_POST['hear'];


//validate form data


//validate name is not empty
if(empty($name)){
$formok = false;
$errors[] = "You have not entered a name";
}


//validate email address is not empty
if(empty($email)){
$formok = false;
$errors[] = "You have not entered an email address";
//validate email address is valid
}elseif(!filter_var($email, FILTER_VALIDATE_EMAIL)){
$formok = false;
$errors[] = "You have not entered a valid email address";
}


//send email if all is ok
if($formok){
$headers = "From: contact_form@website.com.au" . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";


$emailbody = "<p>You have recieved a new message from the enquiries form on your website.</p>
<p><strong>Name: </strong> {$name} </p>
<p><strong>Company: </strong> {$company} </p>
<p><strong>Contact number: </strong> {$phone} </p>
<p><strong>Email: </strong> {$email} </p>
<p><strong>Services required: </strong> {$electives} </p>
<p><strong>Message: </strong> {$message} </p>
<p><strong>How did you hear about us?: </strong> {$hear} </p>
<p>This message was sent from the IP Address: {$ipaddress} on {$date} at {$time}</p>";


mail("###","New Enquiry",$emailbody,$headers);


}


//what we need to return back to our form
$returndata = array(
'posted_form_data' => array(
'name' => $name,
'email' => $email,
'telephone' => $phone,
'enquiry' => $electives,
'message' => $message
),
'form_ok' => $formok,
'errors' => $errors
);




//if this is not an ajax request
if(empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) !== 'xmlhttprequest'){
//set session variables
session_start();
$_SESSION['cf_returndata'] = $returndata;


//redirect back to form
header('location: ' . $_SERVER['HTTP_REFERER']);
}
}

-----------------

 

And this is the HTML form code:

----------------

<?php
			//init variables
			$cf = array();
			$sr = false;
			
			if(isset($_SESSION['cf_returndata'])){
				$cf = $_SESSION['cf_returndata'];
			 	$sr = true;
			}
            ?>
            <ul id="errors" class="<?php echo ($sr && !$cf['form_ok']) ? 'visible' : ''; ?>">
                <li id="info">There were some problems with your form submission:</li>
                <?php 
				if(isset($cf['errors']) && count($cf['errors']) > 0) :
					foreach($cf['errors'] as $error) :
				?>
                <li><?php echo $error ?></li>
                <?php
					endforeach;
				endif;
				?>
            </ul>
