 | This template is used on 210,000+ pages. To avoid large-scale disruption and unnecessary server load, any changes to this template should first be tested in the template's /sandbox or /testcases subpages, or in your own user space. The tested changes can then be added in one single edit to the template. Please consider discussing any changes on the talk page before implementing them. |
This module does the processing for three userbox templates, {{Userbox}}, {{Userbox-2}} and {{Userbox-r}}.
| Template | Description | Examples | |||
|---|---|---|---|---|---|
{{Userbox}}
|
Makes userboxes with an id on the left-hand side, or with no id. |
| |||
{{Userbox-2}}
|
Makes userboxes with an id on both the left- and right-hand sides. |
| |||
{{Userbox-r}}
|
Makes userboxes with an id on the right-hand side. |
|
To use any of these templates from a wiki page, please see the individual template pages for documentation. To generate userboxes directly from Lua, read on.
Generating userboxes from Lua
[edit]To generate a userbox directly from Lua, first load the module.
local userbox = require('Module:Userbox')
You can then run any of the three templates with the code:
userbox.main(functionName, args)
For {{Userbox}} use the function name "_userbox"; for {{Userbox-2}} use the function name "_userbox-2"; and for {{Userbox-r}} use the function name "_userbox-r". The args parameter is a table of arguments to pass to the different userbox functions. To see a list of valid arguments, please consult the individual template pages.
