Form Validation and Submission problem in PHP

I am newbie and I am trying to simple form submission with validation (not tidy validation).
My PHP code is here:

<html>
<head></head>
<title>Form Handling</title>
<body>

<h1>Contact Form</h1>
<form name="form1" action="contact_val.php" method="POST">
Name <input type="text" name="fname"><br><br>

<input type="submit" name="submit" value="Submit">
</form>

<?php

if ($_SERVER['REQUEST_METHOD'] == "POST"){

$fname = $_POST['fname'];

if (!isset($fname) or empty($fname)){

    echo "Please enter name!";


  }


}
?>

I just want to know how to redirect on this page again if input is blank and submit button clicked otherwise go to action page.

You can seperate the this File into two file. html based content with ".html", php tag contetn with ".php", then write php file.

if ($_SERVER['REQUEST_METHOD'] == "POST"){
$fname = $_POST['fname'];
if (!isset($fname) or empty($fname)){
echo "Please enter name!";
}
header("location: (html page url)"); }
?>
Write this code
