Mates,
I am studying on a web questionnaire and to prevent cheating, I need some knowledge. Is there any way to prevent visitors to go back (if any goes back he must run across a timed out page), and to prevent refreshing the page( if any refreshes he must be redirected to a error page or timed out page).
Thanks in advance

I think you are going to need to use a client-side language like javascript.

You might want to look at something like QuizFaber - http://www.lucagalli.net/index.html - http://www.lucagalli.net/index.html They have a fairly active support forrum, and I'm sure this problem's been addressed at some point. -------------

Why use something so unreliable and not doing with plain and simple ASP? When you load the test page, just write into the database: username, time, testID. Then when loading the page, all you have to do is to check wether the user has done the test or not. If he took the test, you would write a message to him, "Sorry, you are only allowed to take the test once", if not, he will go on with the test. But you have to make sure that you write somewhere in the page to warn him not to refresh the page or use the back button. Of course, you can just write a cookie, but if he would have them disabled... ------------- Cristian Banu http://www.soft4web.ro - Soft 4 web |

| Problem is not to compel people to take the test once only. The main problem is when a person gives a wrong answer at 6th question, he can't go back and correct the answer and go on 7th question. If he tries to go back to question he must come across a timed out page. And he mustn't refresh on a page that contain a hard question to retrieve a simplier question. |

I don't get it. How many questions do you show on a page? Because if you show multiple questions, there is no way you could prevent him to change an option to a question in the page. Like any form, you can modify any of your choices untill you hit the submit button. After that, you can't modify it anyway.

kind of like what somone else said, you could store the answers in a database, then when they go back and try to redo 6 it says "sorry you have already answered this" and show 7 or just show 7 but ignore 6 if it was already answered meaning they think they "hacked" it but didnt you could use it for them to review their results at the end aswell ------------- S2H.co.uk - http://www.s2h.co.uk/wwf/" rel="nofollow - WebWiz Mods and Skins For support on my mods + skins, please use http://www.s2h.co.uk/forum/" rel="nofollow - my forum . |
