<script type="text/javascript">

</script>
<?php
$ImageUploaderFlash = new ImageUploaderFlash("ImageUploaderFlash1");
//...other params...
$ImageUploaderFlash->getClientEvents()->setBeforeUpload("ImageUploaderFlash1_BeforeUpload");
//...other params...
$ImageUploaderFlash->render();
?>
function ImageUploaderFlash1_BeforeUpload(){
//...your code...
}
$au.imageUploaderFlash({
events: {
//...other params...
beforeUpload: [ImageUploaderFlash1_BeforeUpload],
//...other params...
}
})
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.
