Seems like rocket science to get the proper informatiion but here is some code I whipped up this afternoon.

I needed a way for users of my site to log into my main site using their forum username and password and I thought this would help others trying to do the same.

PHP Code:


			
<?

$server=ENTER VBULLETIN SERVER IP HERE;

$databaseusername=ENTER VBULLETIN DATABASE USERNAME HERE;

$databasepassword=ENTER VBULLETIN DATABASE PASSWORD HERE;

$databasename=ENTER VBULLETIN DATABASE NAME HERE

$chandle =mysql_connect ($server, $databaseusername", $databasepassword);

if (!mysql_select_db($datababasename, $chandle)) die("can't select database");

$username=mysql_real_escape_string($_REQUEST['username']);

$password=mysql_real_escape_string($_REQUEST['password']);

$pass=false;

$passworderr="please enter a password";

$usernameerr="please enter a username";

if (($username<>"") && ($password<>""))

    {

    $sql="SELECT username,password,salt FROM `user` WHERE username='".$username."' LIMIT 0 , 1";

    $sresult = mysql_query($sql);

    if (!$sresult) die ("bad sql in username lookup ".$sql." ".mysql_error());

    $row=mysql_fetch_array($sresult);

    if (mysql_affected_rows()==1)

        {

        if (md5(md5($password) . $row['salt']) == $row['password'])

            $pass=true;

        else

            $passworderr="<b>invalid password</b>";

        }

    else

        $usernameerr="<b>username not found</b>";

    }



if ($pass==true)

    {?>

    Thank you for logging in

<?     }

else

    {?>

    <form type="post">

    <table>

        <tr>

        <td align=right><? echo $usernameerr ?></td>

        <td><input type=text name=username value="<?echo $username ?>" width=20></td>

        </tr>

        <td>

        <tr>

        <td align=right><? echo $passworderr ?></td>

        <td><input type=password name=password value="<?echo $password ?>" width=20>

        <input type=submit value="log in">

        </td>

        </tr>

    </table>

<?    }?>

I have wordpress installed in the root. I don't show its login box to my users, neither ask them to register in wordpress. I wonder if I can use this integration in wordpress pages?

Thanks for the code. There's a typo.

$row['password])

Should be:

PHP Code:


			
$row['password'])

Thanks,
