Functions to define and modify content types.

Each content type is maintained by a primary module, which is either node.module (for content types created in the user interface) or the module that defines the content type by providing configuration file.

During node operations (create, insert, update, view, delete, etc.), there are several sets of hooks that get invoked to allow modules to modify the base node operation:

  • All-module hooks: This set of hooks is invoked on all implementing modules, to allow other modules to modify what the primary node module is doing. For example, hook_node_insert() is invoked on all modules when creating a forum node.
  • Field hooks: Hooks related to the fields attached to the node. These are invoked from the field operations functions described below, and can be either field-type-specific or all-module hooks.
  • Entity hooks: Generic hooks for "entity" operations. These are always invoked on all modules.

Here is a list of the node and entity hooks that are invoked, and other steps that take place during node operations:
