Prevent access via entering url in address bar of web page

[kgizo]

Hello

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

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 ..
