Template:User book
This userbox declares that the user contributes to a certain wikibook, and adds the user to a category associated with that book. The appearance of the userbox for a given book can be customized by that book.
Usage
[edit source]The template takes one required, unnamed parameter, which is the title of the book. For example,
{{User book|Using Wikibooks}}
would produce
 | This user contributes to the Using Wikibooks wikibook. |
The template adds the user to Category:Book:{{{1}}}/Users, where {{{1}}} is the title specified. In the example above, the user would be added to Category:Book:Using Wikibooks/Users. Calling the template with parameter nocat set to any non-null value will suppress this category, as in
{{User book|Using Wikibooks|nocat=1}}
Customization per book
[edit source]By default, the userbox looks like this:
| This user contributes to the [[]] wikibook. |
To specify a different appearance for a book called Title, create a template called Template:Title/User book, containing markup
{{User book/Custom|{{{1}}}|{{{2}}}|...}}
where ... are named parameters that will be passed to template {{Userbox}}. The parameters supported are (as of this writing) all those documented for {{Userbox}} except
info, usercategory2, and usercategory3.
If usercategory is specified, it overrides the default name for the category; and if nocat is specified with a non-null value, it prevents the category from ever being used (so that it then doesn't matter whether or not the call to {{User book}} uses nocat).
For example, the userbox is customized for Wikijunior:Languages by means of {{Wikijunior:Languages/User book}}, so that
{{User book|Wikijunior:Languages}}
produces
 | This user contributes to the Wikijunior:Languages wikibook. |
A list of all these customizing templates is provided by Category:User book templates.
Internals
[edit source]If the book has no customizing user template, this template calls {{User book/Custom}}. If the book does have a customizing user template, this template calls that customizing template. Either way, the first unnamed parameter to the called template is the book name (the first unnamed parameter to this template); and the second unnamed parameter to the called template is the value of the nocat parameter to this template. {{User book/Custom}} suppresses categorization in response to either the second unnamed parameter or to parameter nocat.
