$Uploader->getClientEvents()->setBeforeUpload("Uploader1_BeforeUpload");
//...other params...
$Uploader->render();
?>
JavaScript

beforeUpload: [Uploader1_BeforeUpload],

Return Value
Type: Boolean
If false (or zero), the upload is cancelled. Otherwise, upload begins immediately after the event handler finishes.
This makes the event handler convenient for validating additional data provided by a user.
