Your own userdb plugin

If you have an existing user database and management system, you'll
probably like to just reuse that one for ewiki. In this case you just
needed to write a custom ["auth_userdb"] plugin.

  <?php
      define("EWIKI_PROTECTED_MODE+", 1);
      define("EWIKI_AUTH_DEFAULT_RING+", 3);    // read-only for unregistered
      $ewiki_plugins["auth_userdb"][] = "my_userdb";

      function my_userdb($user,$pw) {
         $result = mysql_query("SELECT * FROM users
                                WHERE user='$user'");
         if ($row = mysql_fetch_array($result)) {
            if ($flags & USERFLAG_ADMIN) {
               $ring = 1;    // moderator user
            } else {
               $ring = 2;    // ordinary user, may edit/ pages
            }
            return(   array($row["password"], $ring)   );
         }
      }
  ?>

In this example, we fetched the user data from a MySQL database table
'users' with the rows 'name' containing the usernames, 'password'
containing encrypted or unencrypted (?don't care) password. The 'flags'
database column also tells wether the fetched user gets moderator
priviliges (ring 1) or not (ring level 2).

Most SQL user databases are layed out like this one, despite the
fictional 'flags' column of course. If your database had an 'email'
field as well, you could add this to reflect it:
  $GLOBALS["ewiki_author"] = $row["email"];

prev << "Your own userdb plugin"
next >> "Your own perm plugin"
