I have been looking around here to find an answer to my question. I have implemented a html form in my index.html.
    <div id="contact" name="contact">
      <div class="container">
        <div class="row">
          <h2 class="centered">Support</h2>
          <hr class="red">
          <p>For more info and support, contact us</p>
          </div>
          <div class="centered"> <i class="fa fa-envelope-o fa-2x"></i>
          </div>
        </div>
        <div class="row">
          <div class="col-lg-8 col-lg-offset-2 centered">
            <form action="send_form_email.php" method="post" enctype="text/plain" id="contact" method="post" class="form" role="form">
              <div class="row">
                <div class="col-xs-6 col-md-6 form-group">
                  <input class="form-control" id="first_name" name="first_name" placeholder="Name" type="text" required />
                </div>
                <div class="col-xs-6 col-md-6 form-group">
                  <input class="form-control" id="email" name="email" placeholder="Email" type="email" required />
                </div>
              </div>
              <textarea class="form-control" id="comments" name="comments" placeholder="Message" rows="5"></textarea>
              <div class="row">
                <div class="col-xs-12 col-md-12">
                  <button class="btn btn btn-lg" type="submit">SEND</button>
                </div>
              </div>
            </form>
            <!-- form --> 
          </div>
        </div>
        <!-- row --> 
      </div>
</div>
How can my readers send an email directly through the form without using "mailto" From what i have read i have to use a .php document also. I have tried this one:
<?php
if(isset($_POST['email'])) {
    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "you@yourdomain.com";
    $email_subject = "Your email subject line";
    function died($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['first_name']) ||
        !isset($_POST['last_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }
    $first_name = $_POST['first_name']; // required
    $last_name = $_POST['last_name']; // required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $comments = $_POST['comments']; // 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 />';
  }
    $string_exp = "/^[A-Za-z .'-]+$/";
  if(!preg_match($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
  if(!preg_match($string_exp,$last_name)) {
    $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
  }
  if(strlen($comments) < 2) {
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }
  if(strlen($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);
    }
    $email_message .= "First Name: ".clean_string($first_name)."\n";
    $email_message .= "Last Name: ".clean_string($last_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\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);  
?>
<!-- include your own success html here -->
Thank you for contacting us. We will be in touch with you very soon.
<?php
}
?>
But it only takes me to a blank page.. domain.com/send_form_email.php
What changes need to be done on the .php page in order to complete it? As you probably understand a programmer made the html page, but he went incognito.
Sorry about my english skills.
