If you want to use PHP you could do the following:
A the top of the page:
Code:
<?php
if (isset($_POST['emailSubmit']))
mail($_POST['emailTo'], $_POST['emailSubject'], $_POST['emailBody']);
?>
Then use this as your form:
Code:
<form method="POST" action="<?php echo $_SERVER['PHPSELF']; ?>
<input type="hidden" name="emailTo" value="whoToSendTo@Somewhere.com" />
<input type="text" name="emailSubject" />
<textarea name="emailBody"></textarea>
<input type="submit" name="emailSubmit" value="Send Email" />
</form>
Just replace =>
whoToSendTo@Somewhere.com, with whoever you want the email to go to.
