I made some time to fix your code but phdr made a better post for you to follow. I will still post my code since i made time to write it:

<?php
$nameErrorMessage = "Please enter a valid name."; //or something more friendly like "Oops! the name field has an error. Please correct the error."
$nameError = 0;

if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $inputName = trim($_POST["contact-name"]);
  $showInputName = htmlentities($inputName, ENT_QUOTES, "UTF-8");

  if (!$inputName) {
     $nameError = 1;
  } else {
?>
    <html>
    <head>
      <title>Name Form</title>
    </head>
    <body> 
       <div><?php echo $showInputName; ?></div>
    </body>
    </html>

<?php
  exit; }
}
  header("Content-Type: text/html; charset=utf-8");
?>
  <html>
  <head>
    <title>Name Form</title>
  </head>
  <body>
      <form id="contact-form" method="post" action ="">
        <div>
          <label for="contact-name">Name:</label>
          <input type="text" id="contact-name" name="contact-name" value="Placeholder requiring backspace" />
          <?php if ($nameError) { echo $nameErrorMessage; } ?>
        </div>
      </form>
  </body>
  </html>
<?php
  exit;
?>

stick with the format posted by phdr please. I didn’t have time to write it as phdr did. I have to go now. I have physical therapy for my shoulder.
