Re: Going back into the history.

I'm not sure of this because I haven't actually checked, but I believe the difference is that between GET and POST forms... A GET form is basically the same thing as clicking a link (the GET variables are just appended to the URL as a serialized query string), whereas a POST form actually has to include POST variables in the request header somewhere. Might wanna check this out to see if it holds true... don't kill me if it doesn't :) Toby Butzon [ criticism spurs improvement ] ----- Original Message ----- From: "Ben Wiechman" <neteru@aminal.net> To: <php-general@lists.php.net> Sent: Saturday, December 16, 2000 8:19 PM Subject: [PHP] Going back into the history. : Alright, I understand the differnce between php (server-side) and js : (client) so don't bitch about this question and point out the obvious... :) : : I've noticed that when I create pages with php that at times I cannot go : back w/o resubmitting form data.

Some forms I : make seem to make me want to resubmit if I go back on the browser, and some : do not. Can anyone explain where this happens and where this does not. : : Second. Could this potentially be solved (provided that the explanation for : part 1 doesn't take care of it) by using php to parse that last request and : use javascript to insert the previous request to insert into the history. ie : If previously I submitted a form with certain elements, use php to parse : that data, and use a javascript function, possibly linked to onLoad, to : insert the previous request into the history. : If that is an acceptable way to solve that problem, what is the easiest way : to do that. $REQUEST_URI does not store the form elements, unless they are : specifically typed out in the URL. So I'm thinking I would just have to : parse the $GLOBALS array and insert that data into a the old link. Basically : my question is, is there an easier way to do what I want to do? Is there : some way that I can write my scripts so that you don't have expired pages : when you try to go back in the browser history? Will I need to resubmit all : the time even if I do this?
