What are some best practices for handling form actions in PHP, such as triggering actions through links or accessing form element data without using POST or GET methods?

When handling form actions in PHP, it is best practice to use POST or GET methods to access form element data and trigger actions. However, if you need to trigger actions through links or access form element data without using POST or GET methods, you can utilize sessions or hidden fields to pass data between pages. 

// Example of using sessions to pass data between pages
session_start();

if(isset($_POST['submit'])){
    $_SESSION['form_data'] = $_POST;
    header('Location: process_form.php');
    exit();
}

// process_form.php
session_start();
if(isset($_SESSION['form_data'])){
    $form_data = $_SESSION['form_data'];
    // process form data here
    unset($_SESSION['form_data']);
}
