Metadata objects

Metadata objects have been introduce to structurize the information passed between hooks and hookables. In Twig Hooks we have two metadata objects:

• A hook metadata object, which contains information about the hook name, and the hook-level defined context

• A hookable metadata object, which contains information about the hook which rendered it, the merged context, the configuration and prefixes

Accessing a hook metadata

A hook metadata object can be accessed only from a hookable metadata object.

Accessing a hookable metadata

A hookable metadata can be accessed from a Twig template that is a hookable. You can do this by:

• using the hookable_metadata variable which is automatically created for hookables

• using the get_hookable_metadata() function

There is no difference between these two methods, so you can pick the one you prefer the one that best fits your coding style.

There are also Twig functions which are shortcuts for accessing concrete data bags from a metadata object:

• get_hookable_context() for accessing the context

• get_hookable_configuration for accessing the configuration
