This example template shows to use {{#invoke:params|discarding|...}} to check for unknown parameters.
Usage
For instance, writing
{{module:params/doc/examples/check for unknown parameters
| hello = world
| wind = surfing
}}
will generate
- Everything is good: do something
while writing
{{module:params/doc/examples/check for unknown parameters
| hello = world
| wind = surfing
| wrong = ups!
}}
will generate
- Error: The only parameters accepted are
|hello=and|wind=.
For simple cases like this specialized modules are available; you might want to have a look at:
- {{#invoke:Check for unknown parameters|check}}
- {{#invoke:Check for deprecated parameters|check}}
- {{#invoke:Check for clobbered parameters|check}}
- {{#invoke:Parameter validation|validateparams}}
- {{#invoke:TemplatePar|valid}}
