Contact us form

Hi All,

I have created one single page and placed it into the theme directory within the theme itself. named: contactus.php

Within this page if i have paste

<?php
/*
Template Name: Contact us
*/
?>

Within the admin panel i have created one PAGE with this template name tagged. So i am able to paste all the code into the contactus.php and wordpress reads the code of contactus.php

THE CODE:

<?php
/*
Template Name: Contact us
*/
?>
<?php get_header();?>
<?php
$raisedip = $_SERVER['REMOTE_ADDR'];
$lasturl = $_SERVER['HTTP_REFERER'];
$FormError = false;
$FormMessages = array();
if (($_SERVER['REQUEST_METHOD'] == 'POST') && ($_POST['sendit'] == 'yeah')) {
	if (empty($_POST['name']) || ($_POST['name'] == '')) {
		$FormMessages[] = '<div class="error">I can\'t send this without a name</div>';
		$FormError = true;
		}
	if (empty($_POST['email']) || ($_POST['email'] == '')) {
		$FormMessages[] ='<div class="error">I can\'t send this without a valid email</div>';
		$FormError = true;
	}
	if ($FormError == false) {
		$FormMessages[] = '<div class="thanks">Your message has been send succesfully</div>';
			$receiver = '//';
			$subject = "Someone has tried to contact us in regards to ". $_POST['subject'];
			$message = "Name: ". $_POST['name'] ."\nE-mail contact: ". $_POST['email'] ."\nCountry: ". $_POST['country'] .
			"\nSubject: ". $_POST['subject'] ."\nMessage: ". $_POST['message'] ."\r\n";
			$headers = 'From: no-reply <//>' . "\r\n\\";
			wp_mail($receiver, $subject, $message, $headers);
	}
}
?>
<?php
if (!empty($FormMessages)){
	foreach ($FormMessages as $errors) {
		echo $errors.'<br />';
	}	}
?>
	<form method="POST" action="<?php $_SERVER['PHP_SELF']; ?>">
		<table id="contactformtable">
			<legend style="float:right; padding-right:30px;"><h3> Contact us </h3></legend>
				<tr>
					<td>Your name</td>
					<td><input type="text" name="name" maxlength="40"></td>
				</tr>
				<tr>
					<td>Your E-mail address</td>
					<td><input type="text" name="email" maxlength="40">
				</tr>
				<tr>
					<td>Country</td>
					<td><select name="country">
						<option value="nl">Nederland</option>
						<option value="be" selected>Belgie</option>
					</td>
				</tr>
				<tr>
					<td>Subject</td>
					<td><select name="subject">
						<option value="drivers">Drivers</option>
						<option value="cfg">CFG makers</option>
						<option value="website" selected>Website</option>
					</td>
				</tr>
				<tr>
					<td>Message</td>
					<td><TEXTAREA name="message" cols="20" rows="20"></TEXTAREA>
					</td>
				</tr>
					<input type="hidden" name="sendit" value="yeah">
					<input type="hidden" name="ip" value="<?php echo $raisedip; ?>">
					<input type="hidden" name="referer" value="<?php echo $lasturl; ?>">
				<tr>
					<td><input type="submit" name="submit" value="Send"></td>
					<td><input type="reset" name="clear" value="Clear fields"></td>
				</tr>
		</table>
	</form>
<?php get_footer(); ?>

Now when i dont fill in the name and email field, it returns the 2 errors as stated within the if statements.
When i fill in one of the fields it shows the 404 page and the same when i fill in all the field and hit the submit button. Again the 404 page will be shown.

I know this code is not yet finished in regards to the errors but i should say it should work for this far.

Can someone tell me whats wrong ? Why i get the 404 errors when i hit the submit button ?

Cheers
