Question

Posting to /_layouts/15/upload.aspx is not working on SP Subscription Edition

Fernando Vargas 11

In SharePoint 2013 it was possible to post data (files) to /_layouts/15/upload.aspx?IsAjax=1&List={GUID}&RootFolder=/Sites/Site-A/LibraryName as a means to uploading files to a library.
Why is it not working anymore?

I suppose I should have been more detailed in setting up the scenario:

I have a page MyUpload.aspx page with a File control and a button to "Upload". When the upload button is clicked, the File control's files are added to a Form Data object and posted to SharePoint's /_layouts/15/upload.aspx with the IsAjax=1 parameters which causes the files to be uploaded automatically, without user interaction or UI.

From my testing, SP Subscription Edition (SE) the IsAjax parameter is not triggering the file upload. The response content is the page itself instead of the upload complete or progress.

So, adding IsAjax=1 in the UI is not the way to test this as it would not work.

Hi @Fernando Vargas ,
According to my testing, please try to change the "IsAjax=1" as "IsAjax=2",it can upload files.

Here is an example you can refer to:

    /_layouts/15/Upload.aspx?IsAjax=2&List={GUID}&RootFolder=/sites/site/Library-Name

Hi @Fernando Vargas ,
Per my research, no documentation has been found to explain why /_layouts/15/upload.aspx is not working on SharePoint Subscription Edition.
You can try to use the example for uploading files, hope it can help you, thank you for your understanding and support.

Thanks for the response and sample.
However, the way I've done this on SP2013 is using the /_layouts/15/upload.aspx in an ajax call.

See the attached sample. This works nicely on SP2013 but does not in SPSE.
