Manual:Innehåll MediaWiki database layout templatelinks table
MediaWiki-version:
1.6

Tabellen templatelinks innehåller värdsidans ID, namnrymdsnumret för den inkluderade sidan och dess titel utan namnrymd, för varje nuvarande infogning.

Målsidan kan finnas eller inte, och på grund av namnbyten och raderingar kan den hänvisa till olika sidoregister allt eftersom tiden går.

Despite the name, transclusions are not limited to templates, nor to the MediaWiki parser's transclusion mechanism; various extensions use this table to mark that they have incorporated content from another page. (E.g. Scribunto 's {{#invoke:...}} and TemplateStyles 's <templatestyles src="..." /> both record the target page in the templatelinks table.)
