Using the phpBB users table for logging in


See also:
 

This is a very simple hack to get Wikka to read from the users table of a phpBB database rather than its own. It is assuming that you have installed your Wikka into the same database as phpBB and that your phpBB tables are prefixed with "phpbb_" and that their names have not been edited.

This will allow users from your phpBB forum to login to your wiki with their existing username and password.

/Wikka.php
Find:
    function LoadUser($name, $password = 0) { return $this->LoadSingle("select * from ".$this->config['table_prefix']."users where name = '".mysql_real_escape_string($name)."' ".($password === 0 ? "" : "and password = '".mysql_real_escape_string($password)."'")." limit 1"); }


Replace with:
 function LoadUser($name, $password = 0) { return $this->LoadSingle("select * from ".phpbb_."users where username = '".mysql_real_escape_string($name)."' ".($password === 0 ? "" : "and user_password = '".mysql_real_escape_string($password)."'")." limit 1"); }


Find:
 function LoadUsers() { return $this->LoadAll("select * from ".$this->config['table_prefix']."users order by name"); }


Replace with:
 function LoadUsers() { return $this->LoadAll("select * from ".phpbb_."users order by username"); }


Find:
 function GetUserName() { if ($user = $this->GetUser()) $name = $user["name"]; else if (!$name = gethostbyaddr($_SERVER["REMOTE_ADDR"])) $name = $_SERVER["REMOTE_ADDR"]; return $name; }


Replace with:
 function GetUserName() { if ($user = $this->GetUser()) $name = $user["username"]; else if (!$name = gethostbyaddr($_SERVER["REMOTE_ADDR"])) $name = $_SERVER["REMOTE_ADDR"]; return $name; }


Find:
 function SetUser($user) { $_SESSION["user"] = $user; $this->SetPersistentCookie("wikka_user_name", $user["name"]); $this->SetPersistentCookie("wikka_pass", $user["password"]); }


Replace with:
 function SetUser($user) { $_SESSION["user"] = $user; $this->SetPersistentCookie("wikka_user_name", $user["username"]); $this->SetPersistentCookie("wikka_pass", $user["user_password"]); }


/handlers/page/acls.php
Find:
 print("<option value=\"".$this->htmlspecialchars_ent($user["name"])."\">".$user["name"]."</option>\n");


Replace with:
 print("<option value=\"".$this->htmlspecialchars_ent($user["username"])."\">".$user["username"]."</option>\n");

I changed several things in the highscores.php code. Mostly they were changing the "name" to "username" but there was also the table prefix thing that had to be fixed up. Here's the full code:
/actions/highscores.php
<?php
    # highscores.php {{HighScores}}

    $str = 'SELECT Count(*) AS cnt, `username`  FROM phpbb_users, ' ;
    $str .= $this->config["table_prefix"].'pages ';
    $str .= "WHERE `username` = `owner` AND `latest` = 'Y' GROUP BY username ORDER BY cnt DESC;";
    $rankQuery = $this->Query( $str );

    $str = 'SELECT COUNT(*) FROM '.$this->config["table_prefix"].'pages WHERE `latest` = \'Y\' ';
    $totalQuery = $this->Query( $str );
    $total  = mysql_result($totalQuery, 0);

    print( "<blockquote><table>" );

    $i = 0;    
    while( $row = mysql_fetch_array($rankQuery) )
    {
        $i++;
        $str = '<tr>';
        $str .= "<td>$i. &nbsp;</td>";
        $str .= '<td>'. $this->Format( $row["username"] ) .'</td>';
        $str .= '<td> </td>';
        $str .= '<td> &nbsp;&nbsp;&nbsp;</td>';
        $str .= '<td>'.$row["cnt"].'</td>';
        $str .= '<td> &nbsp;&nbsp;&nbsp;</td>';
        $str .= '<td>'. round( ($row["cnt"]/$total)*100, 2).'% </td>';
        $str .= '</tr>';
        print( $str );
    }
    print( "</table></blockquote>" );    
?>
