[MediaWiki-l] Escaping template parameter values

Hi all,

I'm having trouble with user input potentially containing wikitext characters such as }}, {{, |, etc. I'd prefer not to restrict user input and would hope that there's a solution like <nowiki> but for use in templates.

I've tried wrapping the value on the main page with no wiki.

{{AI Comment |Comment author = Gjgeorge |Comment date = 2018-02-13T21:45:25.260Z |Comment text = <nowiki>update }} ! | 1 text</nowiki> |Comment uuid = b8558518-2127-4207-b673-8ac4e5730347 }}

Is there any way to do this?

Thanks,

Garrett
