Description

How to reproduce the issue or how to test the changes

This fixes custom File Upload fields after the first field failing with an "Invalid upload request!" response on new listing submission forms.

Each custom File Upload field generates a separate security token tied to its directory and field key. However, the Plupload initializer reads the first global atbdp_plupload_params configuration for every uploader. The second and subsequent uploaders therefore submitted the first field's token with their own imgid, causing the server-side field/token validation to reject the request.

This change exposes each field's token on its own uploader container and assigns that token to the corresponding Plupload request during the existing initialization loop. The original base configuration remains as a fallback for backward compatibility. No additional requests, database queries, or event listeners are introduced.

1. Go to Directorist -> Directory Builder and add at least three separate File Upload fields to a submission form.
2. Configure the fields to accept PDF files and save the directory.
3. Open the frontend new-listing form where no listing post ID exists yet.
4. Upload a valid PDF to the first, second, and third File Upload fields.
5. Confirm every upload completes without the "Invalid upload request!" error.
6. Verify each AJAX payload contains:
   • action=atbdp_post_attachment_upload
   • the field-specific imgid
   • the matching field-specific upload_token
7. Confirm a form containing only one File Upload field continues to work.
