login credentials not correct

[lovell_82]

Hi there,
I'm trying to setup a website with a database. I want my php code to create the database and then input the data into it, however a get the error on my register page:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user '*****' (using password: YES) in /fg_membersite.php on line 479

Database Login failed! Please make sure that the DB login credentials provided are correct

i've been sitting in front of the computer for the day searching for an answer, so I've finally come to putting up this long code in the hope that someone would be kind enough to shed some light on my situation.

membersiteconfig.php

<?PHP
include'fg_membersite.php';

$fgmembersite = new FGMembersite();

//Provide your site name here
$fgmembersite->SetWebsiteName('');

//Provide the email address where you want to get notifications
$fgmembersite->SetAdminEmail('****@hotmail.com');

//Provide your database login details here:
//hostname, user name, password, database name and table name
//note that the script will create the table (for example, fgusers in this case)
//by itself on submitting register.php for the first time

$fgmembersite->InitDB(/*hostname*/'******.net',
/*username*/'L0v3ll',
/*password*/'sam0531',
/*database name*/'members',
/*table name*/'join');


//For better security. Get a random string from this link: http://tinyurl.com/randstr
// and put it here
$fgmembersite->SetRandomKey('qSRcVS6DrTzrPvr');

Hello, I gave it a really short glimpse but I'm missing the declaration

var $db_host;

you're using $this->db_host, but it is never declared.

[twiss]

Also, are you sure that your hostname ends in .net? It could be, of course, but normally it's just localhost. And, do you need to use this class? There are really strange functions in it. Take a look at mysqli, for example.

[vibhaJ]

Replace this much code and check whether all three values are coming correct or not.
If its correct that means code is right and problem is in mysql credentials.

function DBLogin()
{
echo '--host--'.$this->db_host.'--username--'.$this->username.'--pwd--'.$this->pwd;
$this->connection = mysql_connect($this->db_host,$this->username,$this->pwd);

Ok, first off, is this your code? Be honest. If not, seek out the *genius* who wrote it.

[Wraithmanilian]

the var "pwd" is being used for both the password of the user during registration as well as password for the database. Hope this helps, my 2¢.

Hi guys,
Thanks for looking through the code and helping out. Ardev, it's not entirely my code. I got most of it when browsing the web and came across a share website, I've also gotten help elsewhere. Didn't think this was a crime when they say free to use.

vibhadevit, I get an echo back with my details, then the error

"Warning: mysql_connect() [function.mysql-connect]: Access denied for user in fg_membersite.php on line 480"

[vibhaJ]

Can you use your login credentials in below code and post output.
Because i think there is something wrong in credentials only.

<?php

$db_host = "localhost";
$db_user = "root";
$db_password = "";
$db_database = "db_name"

$link = mysql_connect($db_host, $db_user, $db_password);
if (!$link) {
    die('Not connected : ' . mysql_error());
}

// make foo the current db
$db_selected = mysql_select_db($db_database, $link);
if (!$db_selected) {
    die ('Db selection error : ' . mysql_error());
}

?>

[lovell_82]

Finally it's working,

Thanks entirely to the help of vibhadevit.

Maybe give him some rep?
