How can I maintain state across pages using $_POST?
To maintain state across pages with $_POST, you typically use sessions or hidden fields. Sessions allow you to store user data across multiple pages. Here’s how to use sessions:
<?php
session_start();
if ($_SERVER["REQUEST_METHOD"] === "POST") {
$_SESSION["formData"] = $_POST;
header("Location: next_page.php");
exit;
}
?>In next_page.php, retrieve the data:
<?php
session_start();
if (isset($_SESSION["formData"])) {
$formData = $_SESSION["formData"];
echo "Form Data: ";
print_r($formData);
}
?>Using hidden fields is another approach, but sessions are generally more secure and flexible for maintaining state across pages.
