What are some potential reasons for wanting to submit a form without using JavaScript?

One potential reason for wanting to submit a form without using JavaScript is to ensure that the form can still be submitted even if the user has disabled JavaScript in their browser. In this case, you can use PHP to handle form submission and processing on the server-side without relying on client-side JavaScript. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Example: Save form data to a database
    $servername = "localhost";
    $username = "username";
    $password = "password";
    $dbname = "myDB";

    $conn = new mysqli($servername, $username, $password, $dbname);

    // Check connection
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    }

    $sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";

    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

    $conn->close();
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <button type="submit">Submit</button>
</form>
