What are common issues when passing variables with POST over multiple pages in PHP?

Common issues when passing variables with POST over multiple pages in PHP include losing the POST data when navigating away from the page and having to manually resend the data on subsequent pages. To solve this, you can store the POST data in session variables, which will persist across multiple pages until the session is destroyed. 

// Start or resume a session
session_start();

// Check if form data has been submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Store POST data in session variables
    $_SESSION['variable_name'] = $_POST['variable_name'];
}

// Access the stored POST data on subsequent pages
$variable_name = $_SESSION['variable_name'];
