Cannot use templates in <gallery> caption
Closed, DeclinedPublic

Description

Author: vlakoff

Description:
If I do:

<gallery caption="foo {{some template}} bar">
Image_PlaceHolder.png|Caption of the picture
</gallery>

... the caption isn't expanded at all and displays as "foo {{some template}} bar"

If I do:

{{#tag:gallery|
Image_PlaceHolder.png{{!}}Caption of the picture
|caption=foo {{some template}} bar
}}

... The caption is expanded but HTML code is escaped so it displays as "foo <span><div><sup>[etc.] bar"

An example is provided here: http://fr.wikipedia.org/w/index.php?oldid=70852029

Expected result: The caption should be expanded, ideally in both cases; sadly I presume it would require to add a new syntax, because of the first case.

In order to prove the usefulness of the asked fix:

  • there is no problem in putting HTML elements into a <caption> element[1][2], in case <gallery> would use this element in the future
  • on the French Wikipedia we are working on making accessible abbreviation templates, using <abbr>[3], so that their result is readable by speech synthesizers.

It's not just templates, the parser only calls replaceInternalLinks on the caption. So, in general, wikitext isn't supported in the gallery caption attribute.

We're not intending to do this. Ideally we'd block the #tag hack as well.
