In fine uploader, how to edit/update S3 file metadata for files that are uploaded in previous sessions?

Question

I have requirement in which user need to edit/update the s3 file metadata that are uploaded in the previous sessions. I have implemented Initial File List, but I need to make f

Answer 1

When user click on 'Update Caption', it follows DELETE steps and since I am passing Caption param, it updates S3 file. But problem is in the file list, I will see a status text called 'Deleting.....' appears for brief time. How can I change status to 'Updating Caption....' or something similar

There are various text options you can set for the delete file feature, such as deleteFile.deletingStatusText.

As you can see in the deleteFile section of JS, caption is taken from document.getElementById('caption').value; that means, even if I click 'Update Caption' of 2nd or 3rd or 4th files, it is taking first occurrence of Caption element. How can I get the caption of the specific file ?

Your markup/template is flawed in that you will end up with multiple elements with an ID of "caption". This is not allowed in HTML. You'll need to restructure your markup accordingly. An ID is not appropriate here. Instead, use a class. You can always get the container element for a file using Fine Uploader's getItemByFileId API method. With this, you can query the descendant elements to look for one with a specific attribute.

Last but not least, how can I show 'Update Caption' button only for previously uploaded file. I do not want show this button on fresh upload.

Files submitted by the user (non-canned/initial files) will result in a call to your onSubmitted callback handler after they are represented in the DOM. At this point, you can use the previously mentioned getItemByFileId to retrieve the container element and hide the button.
