    A plugin is some PHP code that

    • lives in phpwiki/lib/plugin/<pluginname>.php
    • implements the WikiPlugin interface by extending that class.

    There are many plugins already distributed with PhpWiki. Simply look in the lib/plugin directory or see the PluginManager list.

    To write your own, look at the HelloWorldPlugin? (HelloWorld.php in that directory), which is a minimal example of a plugin. Publish your self-written plugin at a new PhpWiki page with PluginName + Plugin appended and add a link to CategoryContributedPlugin.

    A Help:WikiPlugin allows one to easily add new types of dynamic content (as well as other functionality) to wiki pages within PhpWiki. In this very wiki all actions which are not entirely lowercased are implemented using plugins, and some lowercased convenience actions also. (rename, revert, setacl, diff, ...)

    (The old-style Help:MagicPhpWikiURLs have been replaced by plugins entirely.)

    Example

    Currently, one invokes a plugin by putting something like:

    <?plugin AllPages limit=5?>

    into a regular wiki-page. That particular example produces a list of the first 5 existing pages (via the PageList library).

    All pages in this wiki (824 total):

    |<<   << - 1 / 165 - Next >>   >>|
    |<<   << - 1 / 165 - Next >>   >>|

    Details

    Plugins can take certain named arguments (most do). The values of these arguments can be determined four different ways. In order of precedence:

    1. The plugin invocation can specify the value for an argument, like so:

      <?plugin BackLinks page=OtherPage ?>
    2. The argument can be specified via an HTTP query argument. This doesn't happen (is not allowed) unless the argument is mentioned in the plugin invocation:

      <?plugin BackLinks page ?>
    3. Default values specified in the plugin invocation:

      <?plugin BackLinks page||=OtherPage ?>
    4. The plugin must supply default values for each argument it uses. Such default args may be overriden by URL arguments like so:

        BackLinks?page=ThisPage&sortby=-mtime

      (The BackLinks plugin uses the current page as the default value for the page argument.)

      Most plugins using the PageListLibrary inherit their default arguments from the PhpWiki:PageListLibrary.

    Standard Arguments

    Most plugins display a list of pages, via the PageListLibrary. PageList provides automatic support for those arguments.

    info, exclude, author, owner, creator, sortby, limit, paging, cols, azhead, comma, commasep, ordered

    For details see the PhpWiki:PageListLibrary documentation.

    exclude and pages accept a list of pages. Either as comma-seperated list, supporting glob-style wildcards, or via the <!plugin-list pluginname [args] !> invocation syntax, where pluginname might be any plugin returning a pagelist. See PhpWiki:PluginList.

    Basic Plugin Types

    All these plugins derive from the Help:WikiPlugin class extending the run method, which returns a object tree of HTML objects, and may react on any provided arguments from the WikiPage (see the args below) or optionally overridden by arguments from the url (GET or POST args), if defined via '||='.

    A basic plugin just needs the run() method, and optionally getName, getDescription, getVersion, getDefaultArguments. See the Help:HelloWorldPlugin for a short introduction.

    plugin reacts on its arguments and the request and displays arbitrary HTML.

    plugin-form is used to display a input type=text box for the default argument s.

    plugin-list is used as argument to provide a dynamic list of pagenames.

      <?plugin PluginName  Help:s ...] ?>
      <?plugin-form PluginName  Help:s ...] ?>
      <?plugin PluginName args=<!plugin-list pluginname  Help:s ] !> ?>

    The box Method

    Themes based on the "sidebar" theme may use the box method of any plugin, which displays a title and a condensed content in a box.

    WikiPluginCached

    Plugins deriving from the class WikiPluginCached must also define the methods getPluginType(), optionally getExpire(), managesValidators(), and dependent of the getPluginType the methods to display the possibly cached result.

    getImage(), getMap() or getHtml(),

    optionally also

    getAlt(), getImageType(), embedMap(), embedImg(), embedObject()

    See the config.ini PLUGIN_CACHED_* settings and PhpWiki:WikiPluginCached

    Aktions Seiten

    The term ActionPage refers to a page containing a plugin invocation. An action is together with the pagename argument the a basic PhpWiki argument. It can both be GET or POST actions. Actions are untranslated, always english. Basic (and old) actions are all lowercase, like edit, browse, remove, ... Newer actions in PhpWiki:CamelCase are invoked via plugins on their specific action page.

    We decoupled actions from plugins via action pages for the following reasons:

    1. support translated action buttons and customizable action descriptions.
    2. customize standard actions by tuning the plugin invocation arguments. override or add plugin defaults.
    3. split simple plugins into multiple actions, like RecentChanges/RecentEdits, MostPopular/LeastPopular, AllPages/AllPagesCreatedByMe/AllPagesLastEditedByMe/AllPagesOwnedByMe which differ only in one argument.
    • Those actions which have buttons or links in the theme or are referenced in the standard pgsrc pageset require their (possibly localized) actionpages, otherwise the actions will not work.
    • If the localized actionpage is not found the english version is used.
    • If no actionpage is found, it is recommended to do action=upgrade, which imports all missing and required action pages into the database.

    So for a hypothetical new MyActionPage plugin MyActionPage will invoke the plugin and MyActionPagePlugin is the the description.

    Existing Plugins

    See PluginManager for a detailed list. Most plugins should have their own description page with the name Plugin appended.
