Template:MC/Error/doc

The template returns a state of error, and optionally an error-message text in red (visible for the user).

Usage

The parameter Template:P can be set to the error to display when using this template.

• Template:Tl → Template:Error
• Compare, used in a Parser Function: {{#expr:Foo}} →

If Template:P is unset, no error will be displayed, although it still can be detected by {{#iferror:}}

• Template:Tl → Template:Error

#iferror

The error displayed is detected by the parser function {{#iferror:}}.

• {{#iferror: {{error|Foo}} | {{c|yes}} | {{c|no}} }} → Template:C
• {{#iferror: {{error}} | {{c|yes}} | {{c|no}} }} → Template:C

Tag option

The tag to contain the error message can be given through the Template:P parameter, but it will only accept span, div, p, and strong, since those are the only tags recognized by the {{#iferror:}} parser function. It defaults to strong, the tag generated by most parsers, e.g. by {{#expr:}}.
