(though on what conditions — consult with the template itself)
This meta template returns a state of error, 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
{{error|An exemplary error}}
→ An exemplary error{{error|message=An exemplary error}}
→ An exemplary error{{#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
{{error|An exemplary error demo no tag (default)}}
XYZ → ABC An exemplary error demo no tag (default) XYZ - ABC
{{error|An exemplary error demo span|tag=span}}
XYZ → ABC An exemplary error demo span XYZ - ABC
{{error|An exemplary error demo div|tag=div}}
XYZ → ABCAn exemplary error demo divXYZ - ABC
{{error|An exemplary error demo p|tag=p}}
XYZ → ABCAn exemplary error demo p
XYZ - ABC
{{error|An exemplary error demo strong|tag=strong}}
XYZ → ABC An exemplary error demo strong XYZ
The template returns a state of error (recognized as such by a wiki parser function), an error-message text in red (visible for the user) and adds the page to "Template errors" category.
