794 // Revision 1.45 2003/12/09 20:00:43 carstenklapp
795 // Bugfix: The last BogoUserPrefs-bugfix prevented the admin from saving
796 // prefs into his own homepage, fixed broken logic. Tightened up BogoUser
797 // prefs saving ability by checking for true existance of homepage
798 // (previously a page revision of 0 also counted as valid, again due to
799 // somewhat flawed logic).
801 // Revision 1.44 2003/12/06 04:56:23 carstenklapp
802 // Security bugfix (minor): Prevent BogoUser~s from saving extraneous
803 // _pref object meta-data within locked pages.
805 // Previously, BogoUser~s who signed in with a (valid) WikiWord such as
806 // "HomePage" could actually save preferences into that page, even though
807 // it was already locked by the administrator. Thus, any subsequent
808 // WikiLink~s to that page would become prefixed with "that nice little"
809 // UserIcon, as if that page represented a valid user.
811 // Note that the admin can lock (even) non-existant pages as desired or
812 // necessary (i.e. any DB page whose revision==0), to prevent the
813 // arbitrary BogoUser from saving preference metadata into such a page;
814 // for example, the silly WikiName "@qmgi`Vcft_x|" (that is the
815 // \$examplechars presented in login.tmpl, in case it is not visible here
816 // in the CVS comments).
818 // http://phpwiki.sourceforge.net/phpwiki/
819 // %C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC?action=lock
821 // To remove the prefs metadata from a page, the admin can use the
822 // EditMetaData plugin, enter pref as the key, leave the value box empty
823 // and then submit the change. For example:
825 // http://phpwiki.sourceforge.net/phpwiki/
826 // _EditMetaData?page=%C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC
828 // (It seems a rethinking of WikiUserNew.php with its WikiUser and
829 // UserPreferences classes is in order. Ideally the WikiDB would
830 // transparently handle such a situation, perhaps BogoUser~s should
831 // simply be restricted to saving preferences into a cookie until his/her
832 // e-mail address has been verified.)
834 // Revision 1.43 2003/12/04 19:33:30 carstenklapp
835 // Bugfix: Under certain PhpWiki installations (such as the PhpWiki at
836 // SF), the user was unable to select a theme other than the server's
837 // default. (Use the more robust Theme::findFile instead of PHP's
838 // file_exists function to detect installed themes).
840 // Revision 1.42 2003/11/30 18:18:13 carstenklapp
841 // Minor code optimization: use include_once instead of require_once
842 // inside functions that might not always called.
844 // Revision 1.41 2003/11/21 21:32:39 carstenklapp
845 // Bugfix: When DEFAULT_LANGUAGE was not 'en', a user's language prefs
846 // would revert to 'en' when the default <system language> was selected
847 // in UserPreferences and the user saved his preferences. (Check for
848 // empty or blank language pref in sanify function of class
849 // _UserPreference_language and return DEFAULT_LANGUAGE if nothing or
850 // default selected in UserPreferences.)
852 // Revision 1.40 2003/11/21 16:54:58 carstenklapp
853 // Bugfix: login.tmpl was always displayed in English despite
854 // DEFAULT_LANGUAGE set in index.php. (Added call to
855 // update_locale(DEFAULT_LANGUAGE) before printing login form).
857 // Revision 1.39 2003/10/28 21:13:46 carstenklapp
858 // Security bug fix for admin password, submitted by Julien Charbon.
860 // Revision 1.38 2003/09/13 22:25:38 carstenklapp
861 // Hook for new user preference 'noLinkIcons'.
863 // Revision 1.37 2003/02/22 20:49:55 dairiki
864 // Fixes for "Call-time pass by reference has been deprecated" errors.
866 // Revision 1.36 2003/02/21 22:50:51 dairiki
867 // Ensure that language preference is a string.
869 // Revision 1.35 2003/02/16 20:04:47 dairiki
870 // Refactor the HTTP validator generation/checking code.
872 // This also fixes a number of bugs with yesterdays validator mods.
874 // Revision 1.34 2003/02/15 02:21:54 dairiki
875 // API Change! Explicit $request argument added to contructor for WikiUser.
877 // This seemed the best way to fix a problem whereby the WikiDB
878 // was being opened twice. (Which while being merely inefficient
879 // when using an SQL backend causes hangage when using a dba backend.)
881 // Revision 1.33 2003/01/22 03:21:40 zorloc
882 // Modified WikiUser constructor to move the DB request for the homepage to
883 // the end of the logic to prevent it from being requested and then dropped.
884 // Added more phpdoc comments.
886 // Revision 1.32 2003/01/21 07:40:50 zorloc
887 // Modified WikiUser::_ok() -- Inverted the logic so the default is to return
888 // false and to return true only in the desired condition. Added phpdoc
891 // Revision 1.31 2003/01/15 05:37:20 carstenklapp
894 // Revision 1.30 2003/01/15 04:59:27 carstenklapp
895 // Bugfix: Previously stored preferences were not loading when user
896 // signed in. (Fixed... I hope.)
