| File:Ambox warning yellow.svg | Due to a server limit of 500 "expensive parser function" calls (e.g. #ifexist:, PAGESIZE:, and PAGESINCATEGORY:), this template will only work properly if the page using it has not already exceeded the limit. When the limit is exceeded, the page using this template or module is categorised in Category:Pages with too many expensive parser function calls. (further information) |
Usage
[edit source]This template (previously called Template:Wikidata red link) takes a Wikidata entity number as an unnamed parameter and provides a link to the corresponding article on the English Wikipedia, or its Wikidata entity depending on whether the article exists or not.
Article exists
[edit source]If the corresponding article exists then a direct link to the article is given (piped to the label on Wikidata).
{{Wikidata fallback link|Q2076202}}→ [[Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value).]]- Explanation: Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value). (Q2076202) has a site link to York, South Carolina. This link is piped to York.
{{Wikidata fallback link|Q6622102}}→ [[Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value).]]- Explanation: Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value). (Q6622102) has a site link to Sunderland Bridge (village). This link is piped to Sunderland Bridge.
Article does not exist
[edit source]If the corresponding article does not exist on the English Wikipedia, then a red link is displayed, followed by a link to its item on Wikidata.
{{Wikidata fallback link|Q1897508}}→ [[Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value).]]- Explanation: There is no English Wikipedia article yet for this insect, so a red link is displayed.
{{Wikidata fallback link|Q31692001}}→ [[Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value).]]- Explanation: There is no English Wikipedia article yet for this mountain, so a red link is displayed.
To suppress the link to Wikidata use |wd=off, e.g.
{{Wikidata fallback link|Q31692001|wd=off}}→ [[Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value).]]- Explanation: The link to Wikidata is not displayed now.
Label exists but article under that title already exists
[edit source]If the corresponding article does not exist on the English Wikipedia but there is a different article at the item's label, then to avoid confusion, the label is not linked.
{{Wikidata fallback link|Q2542189}}→ [[Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value).]]- Explanation: there is no English Wikipedia article for this fictional character "Ali", but the page Ali already exists (cousin of the prophet Muhammad) so no link is provided.
{{Wikidata fallback link|Q18977043}}→ [[Lua error in Module:Wd at line 633: attempt to index field 'wikibase' (a nil value).]]- Explanation: there is no English Wikipedia article for the Dutch street "Bult", but the page Bult already exists (commune in France) so no link is provided.
Article exists but is a redirect to the current page
[edit source]Per WP:SELFRED, if the corresponding article exists but is a redirect to the current page, the label is not linked when the |r=1 parameter is supplied. If the |r=1 parameter is not supplied, the self-redirect is linked as usual.
Example: See Template:Wikidata fallback link/testcases#Article exists but is a redirect to the current page
No label defined
[edit source]If there is no English label defined on Wikidata, then just a link to the Wikidata item is displayed. To fix this, please add a label to the Wikidata item.
Icon
[edit source]The OOjs UI pen icon can be used instead of the [Wikidata] link.
