A simple example plugin.

Hello,, WikiUser!

From the source of this page:

<?plugin HelloWorld salutation="Hello," name="WikiUser" ?>

PhpWiki's plugin architecture allows you to add custom page elements to your wiki. All you have to do is extend (subclass) the WikiPlugin class and create your output via the run() method, dependend on the Wiki- or Request arguments,

  • either with the predefined HTML classes to create valid XHTML,
  • or by using templates, which are easier customizable, but generally more a mess to use and easier to create invalid XHTML.
