This is the documentation page for Module:Check for unknown parameters

This module may be appended to a template to check for uses of unknown parameters.

Usage[កែប្រែ]

Basic usage[កែប្រែ]

{{#invoke:check for unknown parameters|check
|unknown=[[Category:Some tracking category]]
|arg1|arg2|...|argN}}

or to sort the entries in the tracking category by parameter with a preview error message

{{#invoke:check for unknown parameters|check
|unknown=[[Category:Some tracking category|_VALUE_]]
|preview=unknown parameter "_VALUE_"
|arg1|arg2|...|argN}}

or for an explicit red error message

{{#invoke:check for unknown parameters|check
|unknown=<span class="error">Sorry, I don't recognize _VALUE_</span>
|arg1|arg2|...|argN}}

or to use hidden error messages which can be viewed in the HTML source and a preview error message

{{#invoke:check for unknown parameters|check
|unknown=<span class="error" style="display:none">HIDDEN ERROR: Usage of "_VALUE_" is not recognized</span>
|preview=unknown parameter "_VALUE_"
|arg1|arg2|...|argN}}

Here, arg1, arg2, ..., argN, are the known parameters. Any parameter which is used, but not on this list, will cause the module to return whatever is passed with the unknown parameter. The _VALUE_ keyword, if used, will be changed to the name of the parameter. This is useful for either sorting the entries in a tracking category, or for provide more explicit information.

By default, the module makes no distinction between a defined-but-blank parameter and a non-blank parameter. To only track non-blank parameters use |ignoreblank=1.

Regular expressions[កែប្រែ]

This module supports regular expressions, which are useful when there are many known parameters which use a systematic pattern. For example, template:infobox3cols uses

| regexp1 = header[%d][%d]*
| regexp2 = label[%d][%d]*
| regexp3 = data[%d][%d]*[abc]?
| regexp4 = class[%d][%d]*[abc]?
| regexp5 = rowclass[%d][%d]*
| regexp6 = rowstyle[%d][%d]*
| regexp7 = rowcellstyle[%d][%d]*

to match all parameters of the form headerNUM, labelNUM, dataNUM, dataNUMa, dataNUMb, dataNUMc, ..., rowcellstyleNUM, where NUM is a string of digits.

Example[កែប្រែ]

{{Infobox
| above = {{{name|}}}

| label1 = Height
| data1 = {{{height|}}}

| label2 = Weight
| data2 = {{{weight|}}}

| label3 = Website
| data3 = {{{website|}}}
}}<!-- 
  end infobox, start tracking
-->{{#invoke:Check for unknown parameters|check
| unknown = [[Category:Some tracking category|_VALUE_]]
| preview = unknown parameter "_VALUE_"
| name
| height | weight
| website
}}
