Allow users to bulk upload files

Motivation

Clients have requested the ability to upload multiple media files at once (such as PDF documents). Quickstart 1 offered this functionality, but in Quickstart 2 users can only upload one file at a time.

Proposed Resolution

Describe the solution you'd like

The Media Bulk Upload contrib module could provide the solution: this module seems to be the most popular for bulk or batch uploading of files. Its stable releases are covered by the Drupal security advisory policy. It requires the DropzoneJS module.

Quickstart 1 provided bulk upload functionality via the Plupload module, an Drupal integration for the Plupload widget. However, as of 7/30/2023, less than 500 sites report using the latest, Drupal 10 compatible version of this module.

The solution we choose should allow for the same metadata to be added as when users are uploading a single file (e.g. alt text should be required for images).

Roles and Permissions considerations

A clear and concise description of how each of the following roles would be impacted by this change:

Anonymous user: No impact.
Authenticated user: No impact.
Content editor: A permission may need to be added to allow the bulk uploading of files.
Content administrator: No impact.
Administrator: No impact.
