It looks like you already have code to check for blank entries and code for redirecting the page. I'm not sure what your question is.

hi its generating empty entries into my table(database user table) and also not redirecting to original ie index page

1) It's generating blank rows because you don't stop the code from running if there are blanks.

2) It's not redirecting because you can't send headers after outputting data to the page. All headers must be sent before any other data is sent.
