How would you, create a timed survey or quiz.

The only part  i need help with is the timing element, like it needs to start the timer when the page loads and the timer stops when they submit the quiz/survey.

upon starting the quiz (opening the page or whatever), record a timestamp either in a db, file or session variable.

 

then, upon completion of the quiz, grab a timestamp as well.

 

then, minus the last first timestamp from the last recorded timestamp, and there you go .. the difference would be the total amount time spent taking the quiz.

Alternatively you could use javascript, but it may be better to go with the session idea as javascript can be turned off, and changed and all that stuff

Mkay could you give me the syntax for grabbing a timestamp like as in how you would do what you just said lol

[mikesta707]

you can get a timestamp with the time() function.

 

$timeStart = time();

 

When you submit the form on the processing page you could have

$timeEnd = time();

 

obviously you will need to sent the start time to the next page (through a hidden field, a session, save it to a DB, etc.)

Okay i've got the times set up using cookied variables now i just need to know how i would subtract the two time values, sorry for the really noobish question btw.

You would want to use sessions, not cookies. Otherwise it would be trivial to cheat it. Cookies are stored with the user, session data is stored on the server.
