Creating Vulnerable Website Pages

I have my own website, and I'm thinking of adding some vulnerable pages on it, like HBH I suppose. I know XHTML and starting CSS if that helps.

So, my question is, how do you create vulnerable pages? I have little experience with creating websites (my friend does all the "technical" stuff with the website that him and I own). Once I learn CSS and PHP (or ASP) I will probably create another website of my own, just for experience.

Anyway, does anyone have any tips, howtos etc. on making vulnerable pages?

Thanks in advance.

dont worry, crate some page in php & mysql, if u arent a good coder you'll create vulnerable pages for sure.

LOL! yeah that's right…just cook up some pages and ask some people if they want to try and hack it.and if they succeed, tell you what they did,and how to solve it off course.

Come on guys, seriously.

Well what they said is true :p

But you can have some file uploaders, login boxes, panels, guestbooks etc… Almost anything that takes input and does something with it can be exploited ;)

Thanks :D
