Template:Error/doc
 | This is a documentation subpage for Template:Error. It contains usage information, categories and other content that is not part of the original Template page. |
 | 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
- → An exemplary error
- → An exemplary error
- Compare, used in a Parser Function:
{{#expr:Foo}}→ Expression error: Unrecognized word "foo". {{#iferror:{{error|Foo}} | yes | no }}→ yes
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 #expre. To prevent strong message, use one of the other tags, e.g. tag=span.
- ABC XYZ → ABC An exemplary error demo no tag (default) XYZ
- ABC XYZ → ABC An exemplary error demo span XYZ
- ABC XYZ → ABC An exemplary error demo divXYZ
- ABC XYZ → ABC
An exemplary error demo p
XYZ - ABC XYZ → ABC An exemplary error demo strong XYZ
