  • Purpose: classes useful for writing administration SpecialPages, i.e. pages that interact heavily with database tables.
  • Edits:
    • 2013-01-04 This should be the latest version, but copy on HostGator may have some tweaks to be merged.

 LIBRARY: admin.php - some classes useful for administration functions in MW extensions
 GLOBALS:
   $vgOut is usually set in menu.php
     It must be a descendant of clsRichText, which is defined in richtext.php
 HISTORY:
   2010-04-06

clsAdminTable, clsAdminData, clsAdminData_Logged written (in menu.php) 

   2010-10-25 clsAdminTable, clsAdminData extracted from menu.php
   2012-12-31 clsAdminTable_helper
   2013-01-04 restored _AdminLink() to clsAdminData_helper from old copy of menu.php
     * It was in clsAdminData_helper.
     * Was there a reason it went away? Need to document replacement functionality, if so.

 CLASS: clsAdminTable
 NOTES:
   * TODO: clsAdmin* should be rewritten to use helpers
   * TODO: $vgOut should be an object field, not a global

2010-10-06 (both) Wasn't sure who is using this, so commented it out (not WorkFerret or AudioFerret) VbzAdmin didn't *seem* to be using it... (dynamic) Thought I checked VbzAdmin, WorkFerret, and AudioFerret 2010-10-13 (static) Found that VbzAdmin uses it Actually, this is the "boilerplate" function used by most clsDataSet descendants. 2010-10-13 (dynamic) VbzAdmin::VbzAdminStkItems::Listing_forItem() calls it 2010-11-19 (static) Added handling of new records. 2012-03-31 (static) If I added handling of new records in 2010, it must have gotten removed somehow. Adding handling of new records again. 2012-12-31 After moving this code to clsAdminData_helper, modifying new-record handling to use object field values. Also, no longer any need for a static function, so merging with dynamic version.
