Context Data

Context data consists of component-specific data accessible through MidCOM in the following form:

midcom_core_context::get()->get_key(CONSTANT_NAME);

Optionally, you can supply a context id to get information from a different context than the current:

midcom_core_context::get($context_id)->get_key(CONSTANT_NAME);

Component Context Keys

• MIDCOM_CONTEXT_ANCHORPREFIX: URL Anchor prefix relevant for dynamically loaded components, it includes a trailing slash and will give you the absolute URL to the requested URI of the system. (NOTE: This is not the URI to the component's topic, but the URI you would normally build relative URLs if your component was the primary one.)

• MIDCOM_CONTEXT_CONTENTTOPIC: The Topic object displayed in this request.
