Introduction

The File Display component is used to facilitate the uploading and displaying of 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 form field.

File Display 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. This is added using an ERD

Initial Setup

In order to store an uploaded file the following must be completed.

1. Directory
   1. On your server, create a directory where the files will be uploaded. This should be accessible to the application
   2. In PhixFlow, from the  Administration menu, open System →  Configuration

1. 1. In the System Directories section → File Table Upload Location field, add the address of the directory setup in the first step, e.g. /opt/phixflow/data/file
   2.  save your changes
   3. All uploaded files will now be placed in this directory
2. File Table
   1. On your ERD, add a new  File Table
      1. All the required attributes are added by default
   2. If required, create a relationship between this File Table and your desired target table. The target table will require an attribute with a Type of File in order to create a relationship
      1. For example, if you wish to upload company logos, create a relationship to a your company table, create a logo attribute of the type File and link to the File Table   Primary key
         
   3. Data can now be saved directly to this table or via a relationship
