What could be causing the issue of $_POST not displaying the filled fields properly in PHP?

The issue of $_POST not displaying the filled fields properly in PHP could be due to the form method being set to "GET" instead of "POST" or the form action pointing to a different page. To solve this issue, ensure that the form method is set to "POST" and the form action points to the same page where the PHP code is processing the form data. 

<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <!-- Form fields go here -->
</form>
