/**
|
||
|
|
* Declare triggers (events) for users to assign actions to.
|
||
|
|
*
|
||
|
|
* This hook is used by the trigger module to create a list of triggers (events)
|
||
|
|
* that users can assign actions to. Your module is responsible for detecting
|
||
|
|
* that the events have occurred, calling trigger_get_assigned_actions() to find
|
||
|
|
* out which actions the user has associated with your trigger, and then calling
|
||
|
|
* actions_do() to fire off the actions.
|
||
|
|
*
|
||
|
|
* @return
|
||
|
|
* A nested associative array.
|
||
|
|
* - The outermost key is the name of the module that is defining the triggers.
|
||
|
|
* This will be used to create a local task (tab) in the trigger module's
|
||
|
|
* user interface. A contrib module may supply a trigger for a core module by
|
||
|
|
* giving the core module's name as the key. For example, you could use the
|
||
|
|
* 'node' key to add a node-related trigger.
|
||
|
|
* - Within each module, each individual trigger is keyed by a hook name
|
||
|
|
* describing the particular trigger (this is not visible to the user, but
|
||
|
|
* can be used by your module for identification).
|
||
|
|
* - Each trigger is described by an associative array. Currently, the only
|
||
|
|
* key-value pair is 'label', which contains a translated human-readable
|
||
|
|
* description of the triggering event.
|
||
|
|
* For example, the trigger set for the 'node' module has 'node' as the
|
||
|
|
* outermost key and defines triggers for 'node_insert', 'node_update',
|
||
|
|
* 'node_delete' etc. that fire when a node is saved, updated, etc.
