PHP:

 

And,when I run this program,I get a login box asking for user name & password.When I supply the user name & password I get the above mentioned error messages !
I have already created a password list file,& created a "useraccount" database with a user & password.
Then why i am getting this error?
I should be getting a welcome page which I am not getting.

And my database.class file has this code in line 16 :-

if(!$this->cxn = new mysqli($host,$user,$passwd))

And,line 32 has this :-
if(!$result = $this->cxn->query("SHOW DATABASES"))
Hello...anybody there?

 

The error is telling you that the MySQLi username or password is incorrect.

Note that this username and password has nothing to do with the prompt window that appears.

Ask your host if you're unsure about it.

 

Hello,

Can you please guide me as to how to rectify the error?Where can I find the user name & password for mysqli & how to change it?
Host means?I am using my own wamp server
Please Help...

With Regards
Thanks
