I try to create comments form that has reply button but every time I click reply button it not working at all.
1) you don’t have a reply button (you have a reply link which takes you to the form, but it may be styled as a button though)
2) your form’s button says 'add comment'
3) what do you expect to happen
4) what happens instead
and finally, the mysql functions are deprecated. use the more modern PDO or MySQLi extensions instead.

I have a comments form that when filled in posts the
comments from a text field into a database.
Due to a bit of duff coding (Doh!) the database was not
getting updated and i lost 50 or so posts worth of
comments.
Is there any way of retrieving the posted forms from the
server?
