browser back button keep input values

[radalin]

Hi,

In some sites after submitting a form, when you click on back button of the browser, you see that your old inputs are kept and can be reused. How is this done? Is this the ability of the browser or some sort of other thing?
(Just like this site, in the page where you post a topic, click on back button and then forward button, what you have written in the inputs are not lost.)
How can I do this to my site too? Any help or article or tutorial or any helping material is welcome.

I'm not sure if that's the right place for this topic. I'm sorry if it's wrong.

Thanks.

If the inputs are kept after using the back button, it's because of the caching setup in the browser.  There's nothing in PHP that can do that.  Most browsers have settings to change this behavior.

you can make a back link and use Javascript:history(back); It will solve your problem.

Again, the reaction of the browser will not always be the same.  Using Javascript to go back is the same thing as hitting the back button.

This feature interests me. Is it as simple as (?):
[code]<a href="javascript:history.back()">back</a>[/code]
From what I gather this can cause problems, how is this?
Many thx!
