24 * Template: Parametrized blocks.
25 * Include text from a wiki page and replace certain placeholders by parameters.
26 * Similiar to CreatePage with the template argument, but at run-time.
27 * Similiar to the mediawiki templates but not with the "|" parameter seperator.
28 * Usage: <?plugin Template page=TemplateFilm vars="title=rurban&year=1999" ?>
30 * See also: http://meta.wikimedia.org/wiki/Help:Template
32 * Parameter expansion:
33 * vars="var1=value1&var2=value2"
34 * We only support named parameters, not numbered ones as in mediawiki, and
35 * the placeholder is %%var%% and not {{{var}}} as in mediawiki.
37 * The following predefined variables are automatically expanded if existing:
39 * mtime - last modified date + time
40 * ctime - creation date + time
41 * author - last author
43 * creator - first author
44 * SERVER_URL, DATA_PATH, SCRIPT_NAME, PHPWIKI_BASE_URL and BASE_URL
46 * <noinclude> .. </noinclude> is stripped
49 * - ENABLE_MARKUP_TEMPLATE = true: (lib/InlineParser.php)
50 * Support a mediawiki-style syntax extension which maps
51 * {{TemplateFilm|title=Some Good Film|year=1999}}
53 * <?plugin Template page=TemplateFilm vars="title=Some Good Film&year=1999" ?>
