The file attachment field is for uploading and storing a file. If the uploaded file is an image, the file attachment field can show a preview of the image.
The File Attachment Field has eleven different output formats:
Uploading a file in WorkXpress is easy. In add or edit mode, the File Attachment Field appears as a box with a “Browse” button next to it. Click the box or the button to launch a file upload dialog box, navigate to the file, and click Save. When the Form that the File Attachment Field is on is saved, the file will be uploaded.
To copy a File Attachment's Value in an Action, set the “Full Field” Part of the field you want to set to the “WX Stored Value” of the field you are reading, and the files will copy in the background correctly.
If you have the URL to a file on the internet, you can use an action to push that URL into a File Attachment field, and that file will be downloaded and saved in the File Attachment Field.
