Question

i have a game whene the user can win something.
as soon as he wins he has 60 seconds to fill in his adress name etcotherwise he lose his price and someone else can take it.
when he not fills in the adress in 60 seconds then he gets redirected to a sorry too late page and he lose his price.
when he fills in his adress he gets redirected to a confirmation page and can claim his price.

i made this with php and the counter is in javascript.
the javascript will do the redirect when time = 0

how can i controll that the user either goes to the confirmation page or to the soory to late page.
i’m wondering how i can be sure that the javascript countdown is really counted to zero even wehn the users leaves the page.

thanks a lot

Answer 1

try not to trust only javascript for this job, use php to write the time in the session or an database when the user gets the form to fill in his data – check the difference (with php) between this starting-time and the end-time when the user submits the form to the server
and show him the confirmation when diff<=1min or show him sorry-to-late when diff>1min
