back button
 

hi all can u help me how to get rid of this error:

i try to put a back button on every page and this is my code:

its working but sometimes ill get this "Warning: Page has Expired".How to get rid of this warning?:-/

I suspect these expired pages are forms that you have submitted to your site? If so, this is a common problem with POST unfortunately.

Take a look at some of the google links below for solutions.

In a nutshell, the best way to go about this is to save all the data into hidden elements on the error page, and then have your back button post all that form data back via POST, and repopulate the text fields with that data. Obviously you'll want to invent a scheme where it is all automated, and you just put something like the following as the value for your form text field elements:


So it's all automated up to a point, unless of course you want to use Javascript to make it 100% automatic, though this isn't recommended.

i still dont understand...sory..could u please give me an example code...(procedural please i am not good in oop)

as well as the back button, try implementing the following:

And make sure that everything you posted to the page before the page you are on is carried over. This might cause some slowdown, but it is all I can think of. using GET would work if the code didn't need to be secure.

i also tried that one webtuto but sometimes it also has a page expired
