🗃 New plugin - Multi-Uploader [BUBBLE AWS + UPLOADCARE + FILESTACK + AZURE] BIG Update: 11/06/2018


Hi, so I noticed that it shows a preview of an image that you upload. Can it do that for a PDF or Word doc where you can see the documents content


i can answer that… no you cant… BUT you can use cloud convert to make a thumbnail and then show that after the upload. I would use zapier, send the image to cloud convert… make thumb… then use the cloud convert trigger zap to send the process image back to bubble via api webhook.


Thanks a lot @ryan8 :slight_smile:


Does anyone know how I can get the nice uploading design


It looks like you haven’t added the Initalize workflow:

Best to action on page load.

As for customising the element you can use some custom CSS

Is there anyway to define more than one instance of a accepted file type MIME. As I’d like to only allow uploads that are document types or images e.g. PDF, Doc, JPG - when I type more than one, it doesn’t register.

I thought I’d might be able to feed a list of MIME types as a list of text, but still doesn’t work.

But with doing so, the Uploader element comes up with ‘undefined’.

Would be greatly appreciated if more than one can be defined e.g. we could allow the use of:
image/jpeg, application/pdf
defined in the ‘Accepted FileTypes’

I have been experimenting with the File Type validation but I cannot figure out how to make it work to only accept CSV files. I have tried the following MIME types but it does not filter correctly:


Any ideas on what format I need to use to only allow the user to select a CSV file?


Quick idea, try just

That worked! Never thought to just try the file extension. Thanks!

I seem to be getting allot of errors from this plugin suddenly.



how do you know it’s from this plugin?


yea uploader b is this plugin… i am only using this uploader on this project so its not one of the other ones. I am using two at the same time… i dont know if there is an issue with using 2. I mean they do work… but there are a bunch of errors too.


if you remove 1 of the plugin instances, are the errors gone?


also did you try uninstall and reinstall the plugin


Maybe it’s already asked but any plans on adding: to the plugin? To edit the uploaded content. The developer is open to talk about it :slight_smile:


Still getting this: There are 3 of them and only 1 of them throws the error… the other 2 are fine.

The plugin Multi-Uploader / element Uploader threw the following error: RangeError: Maximum call stack size exceeded

@zeroqode when I set the max to 1 file. On mobile the user is aloud to select multiple images and then when select add it does nothing. Users think the app (upload) doesn’t work + that they can upload multiple files instead of just one. Is there a way for me to fix this or…?

Hope you can help :wink:

*ps the max files does work on desktop.
