Code (markup):

what is my error here?

 

possible reasons:
1. you have not specified password.
2. user name you have used does not have permission to connect.

 

ive tried multiple things and i still get the erorrs?

 

Connection to MySQL haven't been initialized yet. Show us the contents of includes.php.

 

$conn = mysql_connect("".$hostname."","".$data_username."","".$data_password."");  
mysql_select_db("".$data_basename."") or die(mysql_error());  

Code (markup):

is anything wrong with that?

 

Yes.

$conn = mysql_connect("$hostname", "$data_username", "$data_password") or die(mysql_error());  
mysql_select_db("$data_basename") or die(mysql_error());

PHP:

Let us know whether it works or not.

 

i inputted the code to cure this error, and it made no difference

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'cpauser'@'localhost' (using password: NO) in /home/dk/public_html/config.php on line 7

PHP:

EDIT: these are the errors from installing on my web host. the one at the start was from installing locally!

 

config.php contents on the stage, please !?

 

<? 
ob_start();session_start();
$hostname = "localhost"; //your hostname (normally localhost)
$data_username = "dk_sweetus"; //database username
$data_password = "******"; //database password
$data_basename = "dk_sweetcollect"; //database name
$conn = mysql_connect("$hostname", "$data_username", "$data_password") or die(mysql_error());  
mysql_select_db("$data_basename") or die(mysql_error());
$bonuspoints=10; //bonus points awarded for new users
$mainpointsneeded=200; //max number of points needed before user can request voucher
?>

PHP:

thats the config.php file!

 

Your error does not reflect your config file. Are you sure you are including it before starting the MySQL connection?
