Hello all,
I am the admin of a traffic exchange and I have scripted a Trivia game that deliver free credits to members while they surf for credits.

I am looking for a programmer that can write a script that can stop a page from being reloaded and hit back.
When a user finds the page, a random question with four possible answers is displayed. (question.php)

When answering correctly members are taken to answer.php which will check the answer and credit the user account, if this was correct.

My problem is that I cannot work out a way to create an error message in case the user would refresh or hit back answer.php after answering their question. Refreshing the page would continue to credit the user credits count in database with the winning, while hitting back will re-load question.php.

When I wrote the script in oder to check out that users apply the Terms of Service of the site by not refreshing or hitting back, I set up to receive an email for every answer (right or wrong ) given during surfing sessions.

The site has now more that 2500 members now and I start receiving too many of these emails.

I am looking for a PHP programmer that can write a script of this kind,
a script that I can use also on other pages of the site.

Script doesn't need to be installed.

If you are interested please post here or send an email to ct67893@blueyonder.co.uk providing a possible cost for your work.

Thanks a million.

It all depends on how you determine if the user is originally allowed to answer the question.

For example, whats stopping the user from getting the same question twice as he / she browses for credits?

There are a couple of ways you can handle this, but preferably I am guessing you don't want a database full of data. ;-)

send me an email quintin@wakepro.co.nz with some more detail how that happens perhaps I can help you.

if in the php page you put:

PHP Code:

header("cache-control: no-cache"); 

If they hit the back button it will say that the page expired.

I could make some other modifications, email me at gregg.jewell@arecaweb.com
