View source for Template:FormattingError/doc

=== Usage ===
* <nowiki>{{FormattingError|</nowiki>''error message''<nowiki>}}</nowiki>
or
* <nowiki>{{FormattingError|</nowiki>''error message''<nowiki>|nocategory=true}}</nowiki>

When using the '''nocategory''' argument, the error message is displayed as usual, but the page is not added to  [[:Category:Pages with incorrect formatting templates use]]. This is useful in documentation pages for templates that use FormattingError and show what errors they can generate without adding these documentation pages to the category. For an example of this, see {{tl|LinkForElement}}.

This template can be evaluated using the <code>{{#iferror}}</code> parser function:
* <code><nowiki>{{#iferror:{{val|XX}}|error|OK}}</nowiki></code> → <code>{{#iferror:{{val|XX}}|error|OK}}</code>
