/**
* Plugin EditMetaData
*
* This plugin shows the current page-level metadata and gives an
* entry box for adding a new field or changing an existing one. (A
* field can be deleted by specifying a blank value.) Certain fields,
* such as 'hits' cannot be changed.
*
* If there is a reason to do so, I will add support for revision-
* level metadata as well.
*
* Access by restricted to ADMIN_USER
*
* Written by MichaelVanDam, to test out some ideas about
* PagePermissions and PageTypes.
*
* Array support added by ReiniUrban.

// Revision 1.11 2004/06/01 16:48:11 rurban
// dbi->touch
// security fix to allow post admin only.
//
// Revision 1.10 2004/04/18 01:11:52 rurban
// more numeric pagename fixes.
// fixed action=upload with merge conflict warnings.
// charset changed from constant to global (dynamic utf-8 switching)
//
// Revision 1.9 2004/02/17 12:11:36 rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
//
// Revision 1.8 2003/11/27 17:05:41 carstenklapp
// Update: Omit page cache object ('_cached_html') from metadata display.
//
// Revision 1.7 2003/11/22 17:41:42 carstenklapp
// Minor internal change: Removed redundant call to gettext within
// fmt(). (locale make: EditMetaData.php:113: warning: keyword nested in
// keyword arg)
//
// Revision 1.6 2003/02/26 01:56:52 dairiki
// Tuning/fixing of POST action URLs and hidden inputs.
//
// Revision 1.5 2003/02/21 04:17:13 dairiki
// Delete now irrelevant comment.
//
// Revision 1.4 2003/01/18 21:41:01 carstenklapp
// Code cleanup:
// Reformatting & tabs to spaces;
// Added copyleft, getVersion, getDescription, rcs_id.
//
// For emacs users
// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
