/**
|
|
* Index messages for closed threads
|
|
*
|
|
* History and serarch works only for indexed messages.
|
|
*
|
|
* Trigger 'pluginMessageIndex' event. Plugins can use this event to
|
|
* index their own messages.
|
|
*
|
|
* Event listener receives as argument an associative array with following keys:
|
|
* - 'message': associative array with message data;
|
|
* - 'result': array of indexed message data. Default value is boolean false.
|
|
*
|
|
* The 'message' element contains following keys:
|
|
* - 'plugin': string, name of the plugin which sent the message;
|
|
* - 'data': array, data sent by the plugin.
|
|
*
|
|
* Plugin can use the 'result' element to return indexed message data. By default it
|
|
* equals to boolean false. To index message plugin should set this element to
|
|
* an associative array with following keys:
|
|
* - 'kind': int, indexed message kind. It must be one of the core messages
|
|
* kinds, not Thread::KIND_PLUGIN.
|
|
* - 'message': string, text of indexed message.
|
|
* - 'sender_name': string, name of person who sent the message. This field is
|
|
* arbitrary and do not use for some messages kinds.
|
|
* - 'operator_id': int, ID of the operator who send the message. This field is
|
|
* arbitrary and do not use for some messages kinds.
|
|
*
|
|
* If the 'result' element equals to boolean false message will be skipped.
|
|
*
|
|
* Example of event listener is listed below:
|
|
* <code>
|
|
* public function pluginMessageIndexListener(&$args) {
|
|
* // Create shortcut for stored data
|
|
* $data = $args['message']['data'];
|
|
* // Check if message was sent by current plugin
|
|
* if ($args['message']['plugin'] == 'example') {
|
|
* $args['result'] = array(
|
|
* // Plugin should set one of the core message kinds to indexed message
|
|
* 'kind' => Thread::KIND_INFO,
|
|
* // Plugin should set arbitrary text for indexed message
|
|
* 'message' => $data['title'] . ': ' . $data['body']
|
|
* );
|
|
* }
|
|
* }
|
|
* </code>
