|
|
* Links have two ends each pointing to an entry, each entry is a double:
|
|
* - app app-name or directory-name of an egw application, eg. 'infolog'
|
|
* - id this is the id, eg. an integer or a tupple like '0:INBOX:1234'

/**

*
|
|
* To participate in the linking an applications has to implement the following hooks:
|
|
*
|
|
* /**
|

|
|
* *
|

|
|
* {
|
|
* return array(
|
|
* 'query' => 'app.class.link_query', // method to search app for a pattern: array link_query(string $pattern)
|
|
* 'title' => 'app.class.link_title', // method to return title of an entry of app: string/false/null link_title(int/string $id)
|
|
* 'titles' => 'app.class.link_titles', // method to return multiple titles: array link_title(array $ids)
|
|
* 'view' => array( // get parameters to view an entry of app
|
|
* 'menuaction' => 'app.class.method',
|
|
* ),
|
|
* 'view_id' => 'app_id', // name of get parameter of the id
|
|
* 'view_popup' => '400x300', // size of popup (XxY), if view is in popup
|
|
* 'add' => array( // get parameter to add an empty entry to app
|
|
* 'menuaction' => 'app.class.method',
|
|
* ),
|
|
* 'add_app' => 'link_app', // name of get parameter to add links to other app
|
|
* 'add_id' => 'link_id', // --------------------- " ------------------- id
|
|
* 'add_popup' => '400x300', // size of popup (XxY), if add is in popup
|
|
* 'notify' => 'app.class.method', // method to be called if an other applications liks or unlinks with app: notify(array $data)
|
|
* );
|
|
* }
|
|
* All entries are optional, thought you only get conected functionality, if you implement them ...
|
|
*
|
|
* The BO-layer implementes some extra features on top of the so-layer:
|
|
* 1) It handles links to not already existing entries. This is used by the eTemplate link-widget, which allows to
|
|
* setup links even for new / not already existing entries, before they get saved.
|
|
* In that case you have to set the first id to 0 for the link-static function and pass the array returned in that id
|
|
* (not the return-value) after saveing your new entry again to the link static function.
|
|
* 2) Attaching files: they are saved in the vfs and not the link-table (!).
|
|
* Attached files are stored under $vfs_basedir='/infolog' in the vfs!
|
|
* 3) It manages the link-registry, in which apps can register themselfs by implementing some hooks
|
|
* 4) It notifies apps, who registered for that service, about changes in the links their entries
