Form submit

Hello Guys,

hope you can help me.

I'm programming a mobile website as school project . ( m.pension-haus-sonnenschein.de)

The problem is to submit the contact form to my mailadress.

I don't know how must i include the process.

<div data-role="page" data-theme="e" id="kontakt">

<div data-role="header" data-theme="e">

<?php

include 'header.html';

?>

</div>

<div data-role="content">

<p style="font-family: Verdana;">

<form action="" method="post">

<div data-role="fieldcontain">

<label for="name">Name:</label>

<input type="text" name="name" id="name" placeholder="Name" />

</div>

<div data-role="fieldcontain">

<label for="mail">E-Mail:</label>

<input type="text" name="mail" id="mail" placeholder="E-Mail Adresse" />

</div>

<div data-role="fieldcontain">

<label for="betreff">Betreff:</label>

<input type="text" name="betreff" id="betreff" placeholder="Betreff" />

</div>

<div data-role="fieldcontain">

<label for="nachricht">Nachricht:</label>

<textarea cols="40" rows="8" name="nachricht" id="textarea"></textarea>

</div>

<input type="submit" value="Abschicken" />

</form>

</p>

</div>

<div data-role="panel" data-display="overlay" data-position="left" data-theme="e" id="menupanel">

<?php

include 'menu.html';

?>

</div>

<div data-role="footer" data-theme="e">

<?php

include 'footer.html';

?>

</div>

</div>

At which place must i include the submit process?
