$_POST Is empty after submit on simple HTML + PHP

I'm testing some beginners features here and am having some difficulties on checking the $_POST content.

What am I missing here?


<html>
    <body>
        <form action="post.php" method="post" >
            First Number: <input type="text" id="n1" name="n1"> <br> Second Number: <input type="text" id="n2" name="n2" onblur="calcular()"/> <br>
            <input type="text" id="resultado" name="resultado">
            <input type="submit">
        </form>
        

        <script type="text/javascript">
        function calcular() {
        var n1 = parseInt(document.getElementById('n1').value, 10);
        var n2 = parseInt(document.getElementById('n2').value, 10);
        var result = n1 + n2;
        document.getElementById('resultado').value = result;
        }
        </script>
    </body>
</html>

This is post.php:


 <?php   
        
       echo "<pre>"; 
       var_dump($_POST);
       echo "</pre>";

        
        
        ?>
