How to use a file upload message
Saving a message: Always remember to hit 'Save Message' before closing or navigating away from the edit screen.
How to retrieve uploaded files
All files will be uploaded physically to Amazon S3 Service
FileUploadMessage attribute_name should be a name of already registered attribute of type FileCollectionAttribute. The application registers a default
FileCollectionAttribute that is called file_upload and the FileUploadMessage uses that by default. Users can use Create Attribute Modal or admin/dynamic-attributes page to create additional FileCollectionAttribute and use that in the FileUploadMessage.
File Collection is a Composite Collection attribute and currently it contains following properties:
name - the name of the file
size - the size of the file
type - the type of the uploaded file
url - this is a temporary URL to access the uploaded file. By default this link will last 30 minutes. After that time it won't be accessible any more.
The properties of the File Collection attribute can be accessed using indexes. If the name of the attribute is file_upload, then something like this:
file_upload[0]['name']
file_upload[0]['size']
file_upload[0]['type']
file_upload[0]['url']
How to construct a file upload message
When structuring a message, you are able to use multiple different message blocks together to create the message that you are looking for. However, when it comes to ordering and structing these, there are some rules that need to be followed. To learn more about this, please head to the Constructing Messages page for more information.
