When submitting my contact form, I'm getting "No arguments Provided" - php

Question

When I submit the form, I get the statement "No arguments Provide!" however, I have a second website running the same exact form and it completely works. The php file is from the Bootstrap Agency template. Here is the code
HTML
<div class="span9">
<form id="contact-form" class="contact-form" action="contact.php">
<p class="contact-name">
<input id="name" type="text" placeholder="Full Name" value="" name="name" />
</p>
<p class="contact-email">
<input id="email" type="text" placeholder="Email Address" value="" name="email" />
</p>
<p class="contact-phone">
<input id="phone" type="text" placeholder="Phone Number" value="" name="phone" />
</p>
<p class="contact-message">
<textarea id="message" placeholder="Your Message" name="message" rows="15" cols="40"></textarea>
</p>
<p class="contact-submit">
<li><input type="submit" value="Send Message" class="special" /></li>
<li><input type="reset" value="Reset" /></li>
</p>
<div id="response">
</div>
</form>
PHP
<?php
// Check for empty fields
if(empty($_POST['name']) ||
empty($_POST['email']) ||
empty($_POST['phone']) ||
empty($_POST['message']) ||
!filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
{
echo "No arguments Provided!";
return false;
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
// Create the email and send the message
$to = 'yourname#yourdomain.com'; // Add your email address inbetween the '' replacing yourname#yourdomain.com - This is where the form will send a message to.
$email_subject = "Website Contact Form: $name";
$email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nEmail: $email_address\n\nPhone: $phone\n\nMessage:\n$message";
$headers = "From: noreply#yourdomain.com\n"; // This is the email address the generated message will be from. We recommend using something like noreply#yourdomain.com.
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
return true;
?>
Any help will be greatly appriciated.

Answer 1

After digging around for the file, I believe this is the one that works. Here is the code:
<?php
// Check for empty fields
if(empty($_POST['name']) ||
empty($_POST['email']) ||
empty($_POST['subject']) ||
empty($_POST['message']))
/*
!filter_var($_['email'],FILTER_VALIDATE_EMAIL))
{
echo "No arguments Provided!";
return false;
}
*/
if(empty($_POST['name'])) {
echo "Please enter your name."; return false;
}
elseif(empty($_POST['email'])) {
echo "Please enter your email."; return false;
}
if(empty($_POST['message'])) {
echo "Please enter your message."; return false;
}
elseif(empty($_POST['subject'])) {
echo "Statement if there is an error"; return false;
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
// Create the email and send the message
$to = 'youname#yourdomain.com'; // Add your email address inbetween the '' replacing yourname#yourdomain.com - This is where the form will send a message to.
$email_subject = "Website Contact Form: $subject";
$email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nEmail: $email_address\n\nMessage:\n$message";
$headers = "From: noreply#yourdomain\n"; // This is the email address the generated message will be from. We recommend using something like noreply#yourdomain.com.
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
return true;
?>

Answer 2

You are missing method="post" in your form.
<form id="contact-form" class="contact-form" action="contact.php" method="post">

Answer 3

The default method when sending in a form is GET.
So you need:
<form method='post' id="contact-form" class="contact-form" action="contact.php">
