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).

Usage

• {{{{#if:|subst:}}error{{#if:An exemplary error|

|An exemplary error }}{{#if:| |{{{3}}} }}{{#if:| |{{{4}}} }}{{#if:| |{{{5}}} }}{{#if:| |{{{6}}} }}{{#if:| |{{{7}}} }}{{#if:| |{{{8}}} }}{{#if:| |{{{9}}} }}{{#if:| |{{{10}}} }}{{#if:| |{{{11}}} }}{{#if:| |... }}}} → <{{#switch:{{{tag}}}

|p=p
|span=span
|div=div
|#default=strong

}} class="error">An exemplary error</{{#switch:{{{tag}}}

|p=p
|span=span
|div=div
|#default=strong

}}>

• Compare, used in a Parser Function: {{#expr:Foo}} → {{#expr:Foo}}
• {{#iferror:{{error|Foo}} | {{y}} | {{n}} }} → {{#iferror:<{{#switch:{{{tag}}}

|p=p
|span=span
|div=div
|#default=strong

}} class="error">Foo</{{#switch:{{{tag}}}

|p=p
|span=span
|div=div
|#default=strong

}}> | 13pxY | Template: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 #expre. To prevent strong message, use one of the other tags, e.g. tag=span.

• ABC {{{{#if:|subst:}}error{{#if:An exemplary error demo no tag (default)|
