සැකිල්ල:පොත් රාක්කය:Allbooks category?
භාවිතය
[සංස්කරණය]This template takes one unnamed parameter, and looks for an allbooks category for a shelf with that name. Returns non-blank only if the allbooks category exists and is apparently properly set up.
අභ්යන්තර ක්රියාකාරීත්වය
[සංස්කරණය]This template pings the allbooks category, and checks for the correct response by {{පොත් රාක්කය:Allbooks category}}. The correct ping response cannot result if the allbooks category doesn't exist, and is wildly unlikely if the allbooks category isn't properly set up. This template does not use the #ifexist: magic word.
