I have a script to send emails. Can someone help me implement a captcha code validation to it. And also make 'email', 'subject', 'message' mandatory to fill in. And possibly to help me add a 'full name' field.

PHP Code:


			
<html>
<body>
<?php
function checkspam($field)
  {
 
  $field=filter_var($field, FILTER_SANITIZE_EMAIL);
 
   if(filter_var($field, FILTER_VALIDATE_EMAIL))
    {
    return TRUE;
    }
  else
    {
    return FALSE;
    }
  }

if (isset($_REQUEST['email']))
  {//if "email" is filled out, proceed

  //check if the email address is invalid
  $mailcheck = checkspam($_REQUEST['email']);
  if ($mailcheck==FALSE)
    {
    echo "Invalid input";
    }
  else
    {//send email
    $email = $_REQUEST['email'] ; 
    $subject = $_REQUEST['subject'] ;
    $message = $_REQUEST['message'] ;
    mail("eeeee@fffff.com", "$subject",
    $message, "$email" );
    echo "Thank you";
    }
  }
else
  {//if "email" is not filled out, display the form
  echo "<form method='post' action='contact.php'>
 * Email: <input name='email' type='text' /><br />
 * Subject: <input name='subject' type='text' /><br />
 * Message:<br />
  <textarea name='message' rows='10' cols='30'>
  </textarea><br />
  <input type='submit' value='Submit' />
  </form>";
  }
?>

</body>
</html>

All quite useful resources

Having problems with all of them, first one I don't want the the user to enter a specific color, and the second one doesn't tell me how to add a form.

Even if I do it, how would I make i attach to the form, and make other fields mandatory.

Sorry
