PHP

    <?php
    include 'functions.php';

    if (!empty($_POST)){
        $data['success'] = true;
        $_POST = multiDimensionalArrayMap('cleanEvilTags', $_POST);
        $_POST = multiDimensionalArrayMap('cleanData', $_POST);

        // your email adress 
        $emailTo ="[email protected]"; // "[email protected]";

        // from email adress
        $emailFrom ="[email protected]"; // "[email protected]";

        // email subject
        $emailSubject = "Mail from Web Contact Form ";

        $name = $_POST["name"];
        $email = $_POST["email"];
        $comment = $_POST["comment"];
        if($name == "")
            $data['success'] = false;

        if (!preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $email)) 
            $data['success'] = false;


        if($comment == "")
            $data['success'] = false;

        if($data['success'] == true){
            $message = "NAME: $name<br>
                EMAIL: $email<br>
                COMMENT: $comment";

            $headers = "MIME-Version: 1.0" . "\r\n"; 
            $headers .= "Content-type:text/html; charset=utf-8" . "\r\n"; 
            $headers .= "From: <$emailFrom>" . "\r\n";
            mail($emailTo, $emailSubject, $message, $headers);

            $data['success'] = true;
            echo json_encode($data);
        }
    }

Thank you. I changed the code to this :

<?php

include 'functions.php';

if (!empty($_POST)){

  $data['success'] = true;


  //your email adress 
  $emailTo ="[email protected]"; //"[email protected]";

  //from email adress
  $emailFrom = $_POST["email"]; //"[email protected]";

  //email subject
  $emailSubject = $_POST["subject"];

  $name = $_POST["name"];
  $email = $_POST["email"];
  $comments = $_POST["comments"];
  if($name == "")
   $data['success'] = false;

 if (!preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $email)) 
   $data['success'] = false;


 if($comments == "")
   $data['success'] = false;

 if($data['success'] == true){

  $message = "NAME: $name<br>
  EMAIL: $email<br>
  COMMENT: $comments";


  $headers = "MIME-Version: 1.0" . "\r\n"; 
  $headers .= "Content-type:text/html; charset=utf-8" . "\r\n"; 
  $headers .= "From: <$emailFrom>" . "\r\n";
  mail($emailTo, $emailSubject, $message, $headers);

  $data['success'] = true;
  echo json_encode($data);
}`enter code here`
}

I would also like to know if i should use a php_redirect to get the browser to open the html file not the php file

The website is abvconstruction.co.za. If any one can check what is the error on my code

Answer 1

First, you have to add method="post" to your <form>, otherwise it's sending the data with GET.

Also remove these lines, which clear the POST data:

$_POST  = multiDimensionalArrayMap('cleanEvilTags', $_POST);
$_POST  = multiDimensionalArrayMap('cleanData', $_POST);

Answer 2

first remove these line, they clear the post values

  $_POST  = multiDimensionalArrayMap('cleanEvilTags', $_POST);
  $_POST  = multiDimensionalArrayMap('cleanData', $_POST);
