submit 2 different forms in HTML using POST method
===

I have 2 form in one HTML page. One form posts to a database and the other form sends an email with the details in the form. It is quite simple when I think of it, but tried for long without success.

HTML:

        <ul class="slides">
			<li>
				<div id="contactFormContainer" class="container">
					<div class="left">
						<h1 class="uppercase">do you  have project inquiry??</h1>

						<form id="contactForm" method="POST" name="contactForm" action="">
							<fieldset>
								<p> 
									<label for="fullname">Fullname</label> 
									<input name="fullname" id="fullname" type="text">
								</p>
								<p> 
									<label for="email">Email</label> 
									<input name="email" id="contact_email" type="text">
								</p>
								<p> 
									<label for="fullname">Subject</label> 
									<input name="fullname" id="fullname" type="text">
								</p>
								<p> 
									<label for="fullname">Project Description</label> 
									<textarea name="message" id="message" rows="2" cols="20"></textarea>
								</p>
								<p> 
									<input class="btn" id="contactSubmit" type="submit" value="Submit">
								</p>
							</fieldset>
						</form>		
					</div> <!-- end left -->

					<div class="right">
						<span class="head">Twitter Feeds</span>
						<div class="twitter">
							<!-- twitter feed will be generated -->
						</div>
					</div> <!-- end right -->
				</div> <!-- end contact form container -->
			</li>

			<li>
				<div class="head container">
					<h2>coming soon...</h2>
				</div>

				<div class="body container">
					<h1 class="uppercase">Subash.com is coming with new face.</h1>

				</div>

				<div class="footer container">
					<p class="signup"><span class="cursive">sign up</span> ..be the first to be notified</p>

					<div class="inputbox">
					  	<form accept-charset="UTF-8" action="" name="subscribeForm" id="subscribeForm" method="post">
						  
						  	<input class="email_field" id="email" name="email" placeholder="Type your email address..." type="email">
						  	<input class="submit_button" type="submit">

						</form>  
						<div class="status">
							<?php 
								if(isset($status)){
									echo '<p>' . $status . '</p>';
								} else {
									echo '<p class="spam">We will never spam you.</p>';
								}
					  		?>
						</div>
					 </div>
				</div>
			</li>
		</ul>

PHP

        <?php
    require_once('includes/db.php');
    require_once('includes/functions.php');
    require_once('includes/validate.php');

    if($_SERVER['REQUEST_METHOD'] == 'POST'){
	// subscribe form
	$email = trim($_POST['email']);

	if(empty($email) || !valid_email($email)){
		$status = 'Please provide valid email address.';
	} else {
		if(email_exist($email)){
			$status = 'You are already subscribed.';
		} else {
			add_email($email);
			$status = 'Thank you for subscribing.';
		}
	}	
     }

    require 'index.tmpl.php';
    ?> 

This code works exactly expected. But now I need to submit the other form. I tried adding this code inside REQUEST_METHOD check following without success:

        $fullname = $_POST['fullname'];

	if(!empty($fullname)){
		$status = 'sucess';
		echo $status;
	} else {
		echo $fullname;
	}


I also tried doing:

    if (!empty($_POST['contactForm'])) {
       //do something here;
    }
 
    if (!empty($_POST['subscribeForm'])) {
       //do something here;
    }


Is there something I am missing??
