成功完成任务后，在上一页重定向用户

Question

What should be good way to redirect user after successful action like edit or delete any item, in delete condition we could use $_SERVER['HTTP_REFERER'] but in case of edit, we show first of all edit form and then user clicks update, so if we use same approach user would be redirected to edit page not main page. I hope you got idea about my confusion. thanks.

Answer 1

If 'update' is handled through a Form post, just put a hidden input in reflecting the landing spot.

<input type="hidden" name="next_url" value="foo.php" />

The PHP uses the value as the place to redirect to.

<?php
  // Do operations.
  header('Location: '.$_REQUEST['next_url']);

This is especially important because HTTP_REFERER is not guaranteed to work. It works most of the time, but there are issues with relying on it.
