Introduction

The File Display Gallery component is used to facilitate the uploading and displaying of multiple files in PhixFlow. Files are previewed and where this is not possible, a generic placeholder image is displayed. The Serene Grey palette provides a number of templates, below is an example of the File Display Gallery form field.

File Display Gallery components require the following key items in order to function:

1. A directory on the server to store the uploaded files and an entry in the  System Configuration to point at this location
2. A special type of table called a  File Table to hold the information about the uploaded files
   1. This is added using an ERD
3. A  Table containing an attribute called folderId and of type, string, that is related to the above  File Table via this attribute
   1. This is added using an ERD

         2. Type: String
   2. Create a Relationship from the folderId attribute on the File Table to the folderId attribute on the
