 | This template uses Lua: |
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
- <templatestyles src="Template:Mono/styles.css"/>{{error|An exemplary error}} → An exemplary error
- <templatestyles src="Template:Mono/styles.css"/>{{error|message=An exemplary error}} → An exemplary error
- Compare, used in a Parser Function:
{{#expr:Foo}}→ Expression error: Unrecognized word "foo". {{#iferror:{{error|Foo}} | {{y}} | {{n}} }}→
Tag option
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 {{#iferror}} parser function. It defaults to strong, the tag generated e.g. by {{#expr}}. To prevent strong message, use one of the other tags, e.g. tag=span.
- ABC <templatestyles src="Template:Mono/styles.css"/>{{error|An exemplary error demo no tag (default)}} XYZ → ABC An exemplary error demo no tag (default) XYZ
- ABC <templatestyles src="Template:Mono/styles.css"/>{{error|An exemplary error demo span|tag=span}} XYZ → ABC An exemplary error demo span XYZ
- ABC <templatestyles src="Template:Mono/styles.css"/>{{error|An exemplary error demo div|tag=div}} XYZ → ABC An exemplary error demo divXYZ
- ABC <templatestyles src="Template:Mono/styles.css"/>{{error|An exemplary error demo p|tag=p}} XYZ → ABC
An exemplary error demo p
XYZ - ABC <templatestyles src="Template:Mono/styles.css"/>{{error|An exemplary error demo strong|tag=strong}} XYZ → ABC An exemplary error demo strong XYZ
