如何在表单提交上处理PHP会话更新？

Question

Hey Guys, I have this form that when I submit will put into a session variable the items in the form. The form has a self target so after clicking submit, it just refreshes the page.

But I need the page to be refreshed with the newly added session variable items to be echo'd back out. Currently I would need to click refresh again for it to echo out because the session was updated on the 1st session and not yet available until the next page reload.

So how can I achieve what I want? I hope this makes sense...

thanks!

It sounds like you're just wanting to be able to know if the form was submitted?

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    session_start();
    $_SESSION['field1'] = $_POST['field1'];
    echo "field1 = " . $_SESSION['field1'];
} else {
    // show form here
}
?>
