मोड्युल:Check for unknown parameters
This module may be appended to a template to check for uses of unknown parameters.
Usage
सम्पादन करी{{#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
{{#invoke:check for unknown parameters|check|unknown=[[Category:Some tracking category|_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
{{#invoke:check for unknown parameters|check|unknown=<span style="display:none">HIDDEN ERROR: Usage of "_VALUE_" is not recognized</span>|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
.
Example
