history back??

[shadiadiph]

is there a history back function that does not use javascript?

You can store the history in sessions then use the header tag when the user presses the back button, but this would have to postback to the server, so an extra step. But yes it is possible sortof. The first view of the page PHP will not be able to send back unless you use $_SERVER['HTTP_REFERER'], which can be invalid data.

 

 

EDIT: Yea I probably meant that.

Don't you mean $_SERVER['HTTP_REFERER']?

<?php
$back = '<a href="'. $_SERVER['HTTP_REFERER'] .'">BACK</a>';
echo $back;

but like premiso said..it can be invalid data....maybe you can filter out invalid links....
