Event handling
common use
DHTMLX Connector uses events to manage Insert/Update/Delete operations.
The code below shows how to attach event:
$conn->event->attach(event_name,handlerFunc);
Parameters:
- event_name - name of the event.
- handlerFunc - handler function.
Handler functions get one input parameter and this parameter depends on attaching event.
In the following table you'll see a full list of events and the appropriate input parameters of handler functions.
| Event | Input parameter of handler function |
|---|---|
| beforeSort | SortInterface Object |
| beforeFilter | FilterInterface Object |
| beforeRender | DataItem Object |
| beforeProcessing afterProcessing beforeInsert beforeUpdate beforeDelete afterInsert afterUpdate afterDelete | DataAction Object |
| beforeOutput | none |
data behavior models
Starting from version 1.5, the library 'extends' OOP support and allows creating a separate class for events processing. You get the possibility to work with one class that will control all processing instead of working with separate handler functions.
class SomeBehavior{ public function beforeRender($data){ //some logic } ... any other handlers ... } $conn->event->attach(new SomeBehavior());
The handlers of the model class take the same parameters as the ordinary events do.
