linking contact form to an email HTML/PHP - php

Question

I'm trying to make the Contact us form working,
P.S. I'm not a Developer, my coding skills is very limited.
this is the HTML code: (from a template with some adjustments)
<!--Contact Starts -->
<div class="container contactform center">
<h2 class="text-center wowload fadeInUp">Get in touch</h2>
<div class="row wowload fadeInLeftBig">
<div class="col-sm-6 col-sm-offset-3 col-xs-12">
<input type="text" placeholder="Name">
<input type="text" placeholder="Company">
<input type="text" placeholder="Email">
<input type="text" placeholder="Subject">
<textarea rows="5" placeholder="Message"></textarea>
<button class="btn btn-primary"><i class="fa fa-paper-plane"></i> Send</button>
</div>
</div>
and this is the PHP script: (wrote it myself)
$name = $_POST['Name'] ;
$from = $_POST['Email'] ;
$message = $_POST['Message'] ;
$to = "contact#mywebsite.com" ;
$subject = "Website Contact Form" ;
mail ($to, $subject, $message, "From: " . $name . $company . $email) ;
echo "Your Message Has Been Sent" ;
I'm not sure what I did wrong, but it's not workign.
the php file called emailscript.php located at /assets/php/emailscript.php
right now I'm getting an error this error: "Not Found
The requested document was not found on this server."

Answer 2

Please put your form elements in <form> tag. And give each element a name attribute.by using name attribute we will get form data in php.
<form name="contact" action="/assets/php/emailscript.php" method="POST">
<input type="text" placeholder="Name" name="contact_name">
<input type="text" placeholder="Company" name="company">
<input type="text" placeholder="Email" name="email">
<input type="text" placeholder="Subject" name="subject">
<textarea rows="5" placeholder="Message" name="message"></textarea>
<button class="btn btn-primary"><i class="fa fa-paper-plane"></i> Send</button>
</form>

Encircle your code in isset function to avoid any error
<?php
if(isset($_POST['Name']))
{
$name=$_POST['Name'] ;
$from=$_POST['Email'] ;
$message=$_POST['Message'] ;
$to="contact#mywebsite.com" ;
$subject="Website Contact Form" ;
mail ($to, $subject, $message, "From: " . $name . $company . $email) ;
// it echo not eco
echo "Your Message Has Been Sent" ;
}
?>
