Extending templates

You may wish to extend templates for a variety of reasons. For example, a plugin may wish to display extra information after the page footer, or add a new feature to user profiles.

Plugins

Plugins extend themes as part of their main plugin class, as part of the registerPages() method.

This is how the Checkin plugin adds some mapping JavaScript to the HTML page header::

\Idno\Core\Idno::site()->template()->extendTemplate('shell/head','checkin/head');

Themes

Themes have a special way of extending themes as part of their theme.ini file.
