get the hashed password

I am trying to use bcrypt and I know that the hash is always different when the bcrypt is used, but I am told that I should get the hashed password from the database, and use the non hashed password from the login form, use some method magic, and hey, it should work, right?

I won't paste all the code, just sections that are for the password.

Well, for me that isn't the case and I was wondering if you can take a look my code below. Also its not complete, some things you will see just to test.
