Make PHP mail form - php

Question

I've an HTML contact form and I want to use it in my footer, but I don't know how to do it!!
Here is my form:
<div class="footer-right">
<p>Contact Us</p>
<form action="#" method="post">
<input type="text" name="email" placeholder="Email" />
<textarea name="message" placeholder="Message"></textarea>
<button>Send</button>
</form>
</div>

Answer 1

The <button> tag will not submit the form. You should change it to: <button type="submit">Send</button>
For handling the form you could add something like this in the beginning of your file::
<?
//Mail sending function
$subject = "Web Form";
$from = $_POST['email'];
$to = "youremail#example.com";
//data
$msg = $_POST['message'];
//Headers
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=UTF-8\r\n";
$headers .= "From: <".$from. ">" ;
mail($to,$subject,$msg,$headers);
echo "Mail Sent.";
?>

Answer 2

Since you tagged it as PHP, this answer will get you started.
Change:
<button>Send</button>
to:
<input type="submit" value="Send">
Change:
<form action="#" method="post">
to:
<form action="mailer.php" method="post">
Create a file named mailer.php and place it in the same folder as the filename of the document you presented, and in that file, add the following contents:
<?php
$recipient="receipient#example.com";
$subject="new message from ".$_POST['email']." - contact form";
$message=$_POST['message'];
mail($recipient, $subject, $message);
?>
<p>Your message has been sent.</p>
Note that you should add custom HTML between the last two lines of the above code or your HTML won't validate with W3C standards.
