How can PHP be used to implement a two-stage form approach for editing, deleting, and adding records without relying on JavaScript?

When implementing a two-stage form approach for editing, deleting, and adding records without relying on JavaScript, you can use PHP sessions to store the form data between stages. This allows the user to input information in multiple steps without losing their progress. By utilizing session variables, you can maintain the state of the form across different pages without the need for client-side scripting.

<?php
session_start();

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (!empty($_POST['stage1'])) {
        $_SESSION['stage1_data'] = $_POST['data']; // Store data from stage 1
        // Redirect to stage 2 form
    } elseif (!empty($_POST['stage2'])) {
        // Process data from stage 2
        $stage1_data = $_SESSION['stage1_data']; // Retrieve data from stage 1
        $stage2_data = $_POST['data']; // Data from stage 2
        // Perform necessary actions (e.g. editing, deleting, adding records)
        // Unset session variables to clear data
        unset($_SESSION['stage1_data']);
    }
}
?>
