 | This template is used on approximately 42,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
 | This template uses Lua: |
This meta-template returns a state of error (recognized as such by the wiki parser function {{#iferror}}), and optionally an error-message text in red (visible to the user). It is used by other templates to signal an error (such as those caused by invalid input), which can then either be displayed to the editor or caught and handled by other templates.
Usage
- This page is being depreciated → An exemplary error
- This page is being depreciated → 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.
