如何在使用带有值的按钮重定向到另一页时删除确认表单重新提交

Question

Good day, as the title says, how can I do that? What I'm trying to do is that on page 1, I looped all data with each having a button that has value of their specific id, then that button redirects to a common page 2, then I use that id on page 2 to display their whole data, but the problem is that when I refresh, the dialog appears.

I tried using session, but the problem is that when multiple tabs are accessing it.

I haven't really tried PRG, but on my understanding, it is used to send changes to the server using another page, then redirect to the previous page, preventing the dialog when refreshing. I thought of using it, but I don't know how to send the fetched data from page 1.5 to page 2

I'd be really grateful for a solution to this, or if someone can link me to similar problems. Maybe this is a duplicate question, but I just can't find the term for my problem. Cheers!!

If you control both pages, change the redirect mechanism on page 1 to GET by simply redirecting to a URL with a parameter appended to the address: target.php?id=42.

If you control only page 2, you may convert a POST request with an id to a GET request:

if (isset($_POST['id']))
{
    header('Location: target.php?id=' . $_POST['id']);
    exit;
}
