Um große Unterbrechungen und unnötige Serverauslastung zu vermeiden, solltest du Änderungen an anderer Stelle testen, indem du beispielsweise den Quellcode dieser Vorlage kopierst und in den Benutzerbereich oder in die Sandbox einfügst. Erwäge, deine Änderungen auf der Diskussionsseite vorzuschlagen, bevor du diese Vorlage bearbeitest.

This module creates protection banners and padlock icons that are placed at the top of protected pages.

Usage

Most users will not need to use this module directly. For adding protection templates to pages you can use the {{pp}} template, or you may find it more convenient to use one of the more specific protection templates in the table below.

From wikitext

{{#invoke:Protection banner|main
| 1        = reason
| small    = yes/no
| action   = action
| date     = protection date
| user     = username
| section  = talk page section name
| category = no
}}

The #invoke syntax can be used for creating protection templates more specific than {{pp}}. For example, it is possible to create a protection template which always shows a padlock icon by using the code {{#invoke:Protection banner|main|small=yes}}. Pages which call this template will still be able to use other arguments, like action. However, this only works one level deep; a page calling a template which calls another template containing the above code will not automatically be able to use parameters like action.

Note: You should no longer specify the expiry, as it is automatically retrieved in all cases.

From Lua

First, load the module.

local mProtectionBanner = require('Module:Protection banner')

Then you can make protection banners by using the _main function.

mProtectionBanner._main(args, cfg, titleObj)

args is a table of arguments to pass to the module. For possible keys and values for this table, see the parameters section. The cfg and titleObj variables are intended only for testing; cfg specifies a customised config table to use instead of Module:Protection banner/config, and titleObj specifies a mw.title object to use instead of the current title. args, cfg and titleObj are all optional.

Parameters

All parameters are optional.

  • 1 – the reason that the page was protected. If set, this must be one of the values listed in the reasons table.
  • small – if set to "yes", "y", "1", or "true", a padlock icon is generated instead of a full protection banner.
  • action – the protection action. Must be one of "edit" (for normal protection), "move" (for move-protection) or "autoreview" (for pending changes). The default value is "edit".
  • date – the protection date. This must be valid input to the second parameter of the #time parser function. This argument has an effect for reasons that use the PROTECTIONDATE parameter in their configuration. As of July 2014, those were the "office" and "reset" reasons.
  • user – the username of the user to generate links for. As of July 2014, this only has an effect when the "usertalk" reason is specified.
  • section – the section name of the protected page's talk page where discussion is taking place. This works for most, but not all, values of reason.
  • category – categories are suppressed if this is set to "no", "n", "0", or "false".
  • catonly – if set to "yes", "y", "1", or "true", will only return the protection categories, and not return the banner or padlock. This has no visible output.

Reasons

The following table contains the available reasons, plus the actions for which they are available.

Reason Action Description
blp edit For pages protected to promote compliance with the biographies of living persons policy
dispute edit For pages protected due to editing disputes
dmca edit For pages protected by the Wikimedia Foundation due to Digital Millennium Copyright Act takedown requests
ecp edit For articles in topic areas authorized by ArbCom or meets the criteria for community use
mainpage edit For pages protected for being displayed on the Main Page
office edit For pages protected by the Wikimedia Foundation
reset edit For pages protected by the Wikimedia Foundation and "reset" to a bare-bones version
sock edit For pages protected due to sock puppetry
template edit For high-risk templates and Lua modules
usertalk edit For pages protected against disruptive edits by a particular user
vandalism edit For pages protected against vandalism
dispute move For pages protected against page moves due to disputes over the page title
vandalism move For pages protected against page-move vandalism

Errors

Below is a list of some of the common errors that this module can produce, and how to fix them.

Invalid protection date

Error: invalid protection date ("abc")

This error is produced if you supply a |date= parameter value that is not recognised as a valid date by the #time parser function. If in doubt, you can just use a date in the format "dd Month YYYY", e.g. "31 Dezember 2024". To see a full range of valid inputs, see the #time documentation (only the first parameter, the format string, may be specified).

Invalid action

Error: invalid action ("abc")

This error is produced if you specify an invalid protection action. There are only three valid actions: edit (the default, for normal protection), move (for move-protection), and autoreview (for pending changes). This should only be possible if you are using a template that supports manually specifying the protection action, such as {{pp}}, or if you are using #invoke directly. If this is not the case, please leave a message on Module talk:Protection banner.

Reasons cannot contain the pipe character

Error: reasons cannot contain the pipe character ("|")

This error is produced if you specify a reason using the |1= parameter that includes a pipe character ("|"). Please check that you are not entering the {{!}} template into this parameter by mistake. The pipe character is disallowed as the module uses it internally. A list of valid reasons can be seen in the reasons section.

Other errors

If you see an error other than the ones above, it is likely to either be a bug in the module or mistake in the configuration. Please post a message about it at Module talk:Protection banner.

Technical details

This module uses configuration data from Module:Protection banner/config. Most of the module's behaviour can be configured there, making it easily portable across different wikis and different languages.

General test cases for the module can be found at Module:Protection banner/testcases, and test cases specific to enwiki's config can be found at Module:Protection banner/config/testcases.

Bug reports and feature requests should be made on the module's talk page.
