Storing redirect URLs for future reference

Question

I am trying to save a redirect URL for use on several pages later, but it is difficult for me to figure out how to get it from one place to another.

Usually I just passed the variable through the url, but since the redirect url contains url variables, this does not work.

To give you a better idea of ​​what I'm trying to do, here is the structure.

PAGE 1: User can click the link to add content on the page PAGE 2

PAGE 2: User enters text. Submitting a form on this page calls "formubmit.php", where MySQL data records are processed. At the end of this, I need to redirect the user to PAGE 1 again. The redirect URL must exactly match what was originally on page PAGE 1

Does anyone have any suggestions on this?

Answer 5

You can add this hidden field to your form:

<input type="hidden" name="referer" value="<?php echo $_SERVER['HTTP_REFERER']; ?>">

Then use header()to redirect to this page:

header('Location: '. $_POST['referer']);
