Hi,

I would like to require a description to be added on all photos uploaded. I am using Image Uploader 7 java.

I tried looking for any option for this and did not find it. I also tried looking for an event I could use, or a way I could cancel a fileupload but I did not find one.

Can anyone think of a way I can accomplish this? If a user tries to upload a file without adding a description, I would like to have a message show up somewhere, preferably under the thumbnail, that a description needs to be added.

Thank you.

Hi Kyle,

You should check if your files have descriptions in beforeUpload() event. Please see the code below:

Code:
<script type="text/javascript">
    function onBeforeUpload(){
	var count = $au.uploader('Uploader1').files().count();
	for (var i = 0; i < count; i++)
	{
		if ($au.uploader('Uploader1').files().get(i).description()=="")
		{
			alert("Not all files have descriptions!");
			return false;
		}
	}
	}

var uploader = $au.uploader({
    id: 'Uploader1',
    enableDescriptionEditor: true,
    events: {
	beforeUpload: onBeforeUpload,
    }
});
</script>

beforeUpload event is fired before the upload process starts. It is perfect place to add pre-upload tests. So you get the number of files which are currently in the upload pane. Then you check if each of them has got the description. If no description is set, you notify your users about it and return false as a result value of your function. If onBeforeUpload returns false, the upload process won't be started.

I hope this solution works for you.
