Makien · #1 (**permalink**) 10-07-05, 07:38 PM

I posted on another oart of the board and was instructed my best way to go was php, msql, asp. What I want to do is keep this timer running after the time has been put into feilds.
I'm gonna try to do this with php and need a little (or alot) of help on how to keep timerr alive after enter whether anyones online or not.

Any help is appreciated, thanx

Code:

Hmm... Unsure what you want to accomplish, but as I understand you wand a person enter some values, start the timer and after he/she returns to your page, to see the timer that was ticking all the time?

For that put up a form that will trigger server-side PHP script to store the values in a db or whereever, and on subsequent visits select the value, use difference with current time and come up with a PHP-generated JS that will preset the values on the client side. You can use cookies to identify visitors or have a login system.

If you are looking to store values for everyone you will have to use files or some other method such as a database (for example, a mysql database).

There is actually a bit of work involved, especially if this is the case. You are probably better off putting this in the script request category.
