I've got a problem whereby I need to block access to my survey, I do not want a situation where a user can access the survey by just entering the URL of the survey, the survey has been integrated with mediawiki.
Thanks in advance
Thats what I meant sorry.
It can be easily done .. For example , your web page address is www.example.com/index.php?survey=blahblah you can hash the value of blahblah by using
$survey = "Anything" ; $hashed_survey = md5($survey);
and then continue your document by replacing blahblah with $hashed_survey ..
I'll try it out just now
any of an unlimited number of $session variables set in the page you wish to link from, search for in the page you wish to land on
