Module:checkparams/documentation
Editor info[edit]
If you're seen a warning that "The template does not use the parameter(s)" while editing a page, the error was generated by this module. This module can detect all of the parameters that are used by a template and will generate a warning when a template is called with an unexpected parameter. In many cases, the error might be generated by a typo in the parameter name (eg, "pge" instead of "page") and can simply be corrected by consulting the template's documentation.
If you're absolutely certain that a template should allow the parameter even though it's not going to actually use the parameter, you can override the automatic parameter detection by adding a | plus a comma separated list of additional parameters that should be accepted to the {{#invoke:checkparams|warn}} or the {{#invoke:checkparams|error}} line at the top of the template.
For example, to allow parameters "3" and "comment" in the following template
{{#invoke:checkparams|warn}}<!-- Validate template parameters
-->Written by {{{1}}} and {{{2}}} in {{{year}}}
change it to:
{{#invoke:checkparams|warn|3,comment}}<!-- Validate template parameters
The parameters '3' and 'comment' are not used, but are explicitly allowed because ....
-->Written by {{{1}}} and {{{2}}} in {{{year}}}
