Hi,
I have been trying to create a maintainable way of grouping pages together and allowing readers to page through them in sequence. Most samples I've seen use templates that require you to supply the 'previous' and 'next' page. This however results in three page edits to insert a new page between two existing pages and does not guarantee that your prev-sequence is identical to the next-sequence...
Being a programmer, that is way too much duplicate and error-prone work for me ;-) There must be a better way to do this and I was hoping to solve it with a plain MW installation (with ParserFunctions and DynamicPageList at the moment).
Given an 'index' page that holds a list of all page titles in the preferred order, isn't it possible to create a template that selects the correct previous and next page title given the current page title?
I get stuck in getting the correct lines from the index page. DPL can select based on section name (= page title), but then the contents of that index section must be the prev/next links themselves:
=First Page= Prev [[Second Page|Next]] =Second Page= [[First Page|Prev]] [[Third Page|Next]] =Third Page= .. etc.
This works, except that it is still a lot of duplication of page names (but the edits are contained in a single page, big plus).
I hoped to simplify the index page by creating a template that writes the section header and prev/next links, but then DPL no longer recognizes the sections :-( Apparently DPL 'sees' the page text before the templates are called ({{Page|Prev page|Page title|Next page}}:
{{Page||First Page|Second Page}} {{Page|First Page|Second Page|Third Page}} {{Page|Second Page|Third Page|Fourth Page}}
Basically my questions are: 1. Am I completely off track here? 2. Can DPL be coerced to evaluate templates before looking at the page 3. Can DPL (or another extension) select the text from a section before/after a matched section? 4. Is it possible to determine the section sequence number given the section name (so 'Second Page' results in 2, allowing me to use DPL to retrieve the name of section 2 -/- 1 and 2 + 1 to create the prev/next links?
Apologies for the long post, hopefully someone can point me to some good resources (I've been to Meta, Wikibooks, Medawiki.org but could very well have overlooked something there as the amount of info is a bit overwhelming and it is difficult to judge how up to date it is).
