What’s it doing that you don’t expect? Are you getting an error?

The first thing to do is turn on error reporting, but looking at your HTML and Code there are a lot of things wrong with it. My suggestion would to find a CURRENT tutorial be it a video or a book and go from there.

@skawid i wrote totally a new code now but i couldnt trouble shoot this one , the sign up page returns empty rows on submit

@Strider64 wow soo many mistakes .? But i tried debugging it but didnt find any error through a online tool.

@saleha, when you post, don’t say “not working”. Nobody know what that means. Tell us exactly what problem you are experiencing and the results you are expecting.
