Contact Us Form Help

[Kennett]

I created a contact us form that sends me an e-mail with the person information. The form page name is contact_us.php and it post to mail.php which is working good so I thought. But lately I've been getting a lot of blank emails from the form. What I think is going on is that there are crawlers or people just going to mail.php so it sends a blank email. I edited the source to not allow that but the page is all white and just sits there. What I would like is when someone goes straight to mail.php. It redirects them to contact_us.php. I would also like to make it to where it won't send an email without any contact info from contact_us.php. Here is my code for mail.php

<?php
	if (isset($_POST['Submit']))
	  {
		//gather the data from the form
		$email = $_POST['email'] ;
		$comments = $_POST['comments'] ;
		$fname = $_POST['fname'];
		$lname = $_POST['lname'];
		$email = $_POST['email'];
		$phone = $_POST['phone'];
		$model = $_POST['model'];
		$c_mail = $_POST['c_mail'];
		$c_phone = $_POST['c_phone'];
		$subject = "Contact Us Form Results";
		$headers = "From: {$email}";
		//$headers = "From: Web Site";  
		$message = "Customer Contact Information:\n
		First Name: $fname\n
		Last Name: $lname\n
		Phone Number: $phone\n
		Email: $email\n
		Customer is interested in model: $model\n
		The customer would like to be contacted by: $c_mail   $c_phone\n
		Comments from customer:\n
		$comments\n";
		//send the email
		$send =  mail("[email protected]", $subject, $message, $headers);
		//if the email is sent send to a new page
		  if($send)
		  {
		  header( "Location: thankyou.php" );
		  }
		  //if the message is not sent send them an error
		  else{
		  echo "An error occurred sending your message!!";
		  }
		}
        else{
            header( "Location: contact_us.php");
           }
?>

Thank you for your help in advance.

 

P.S. I'm a noob so sorry if any dumb mistakes or if I don't know what you are talking about or request of me.

You could read up on header and isset

It would also be a good idea to check and make sure all of the required information is filled so blank E-Mails and such aren't sent.
