Module:Error

This meta template returns a state of error (recognized as such by a wiki parser function), and optionally an error-message text in red (visible for the user). It is used by other templates to signal an error, for example invalid input, which can then either be displayed to the editor or caught and handled by other templates.

Usage[edit source]

{{error|An exemplary error}} → Script error: No such module "Error".
{{error|message=An exemplary error}} → Script error: No such module "Error".
Compare, used in a Parser Function: {{#expr:Foo}} → Expression error: Unrecognized word "foo".
{{#iferror:{{error|Foo}} | {{y}} | {{n}} }} → Template:Y

Tag option[edit source]

The tag to contain the error message can be given through the tag parameter, but it will only accept span, div, p, and strong, since those are the only tags recognized by the Template:Pf parser function. It defaults to strong, the tag generated e.g. by Template:Pf. To prevent strong message, use one of the other tags, e.g. tag=span.

ABC {{error|An exemplary error demo no tag (default)}} XYZ → ABC Script error: No such module "Error". XYZ
ABC {{error|An exemplary error demo span|tag=span}} XYZ → ABC Script error: No such module "Error". XYZ
ABC {{error|An exemplary error demo div|tag=div}} XYZ → ABC Script error: No such module "Error". XYZ
ABC {{error|An exemplary error demo p|tag=p}} XYZ → ABC Script error: No such module "Error". XYZ
ABC {{error|An exemplary error demo strong|tag=strong}} XYZ → ABC Script error: No such module "Error". XYZ
