/**

* Declare triggers (events) for users to assign actions to.
|
| 15 |
*
|
| 16 |
* This hook is used by the trigger module to create a list of triggers (events)
|
| 17 |
* that users can assign actions to. Your module is responsible for detecting
|
| 18 |
* that the events have occurred, calling trigger_get_assigned_actions() to find
|
| 19 |
* out which actions the user has associated with your trigger, and then calling
|
| 20 |
* actions_do() to fire off the actions.
|
| 21 |
*
|
| 22 |
* @return
|
| 23 |
* A nested associative array.
|
| 24 |
* - The outermost key is the name of the module that is defining the triggers.
|
| 25 |
* This will be used to create a local task (tab) in the trigger module's
|
| 26 |
* user interface. A contrib module may supply a trigger for a core module by
|
| 27 |
* giving the core module's name as the key. For example, you could use the
|
| 28 |
* 'node' key to add a node-related trigger.
|
| 29 |
* - Within each module, each individual trigger is keyed by a hook name
|
| 30 |
* describing the particular trigger (this is not visible to the user, but
|
| 31 |
* can be used by your module for identification).
|
| 32 |
* - Each trigger is described by an associative array. Currently, the only
|
| 33 |
* key-value pair is 'label', which contains a translated human-readable
|
| 34 |
* description of the triggering event.
|
| 35 |
* For example, the trigger set for the 'node' module has 'node' as the
|
| 36 |
* outermost key and defines triggers for 'node_insert', 'node_update',
|
| 37 |
* 'node_delete' etc. that fire when a node is saved, updated, etc.
