The 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).

  • {{error|An exemplary error}}An exemplary error
  • Compare, used in a Parser Function: {{#expr:Foo}}अभिव्यक्ति त्रुटि: अज्ञात शब्द "foo"।
  • {{#iferror:{{error|Foo}} | {{y}} | {{n}} }}Green tickY

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 → ABC
    An exemplary error demo div
    XYZ
  • ABC {{error|An exemplary error demo p|tag=p}} XYZ → ABC
