This how-to describes how to use the multiple file upload.

...

...

For this the functionality of multiple files you do not need to install any pluginplug in.

Configuration

Please configure the connection in the aquima.properties file in the home folder first. Currently there are two connection flavors:

• Memory

  Code Block
  connection.<connection name>.memory

• File system

  Code Block
  connection.<connection name>.filesystem.path=<your path>

  Replace <your path> with the correct path. Note to use '/' in your path, e.g. C:/Files/.

Also check that your language properties file (e.g. messages_en-GB) contains the following lines:

#fileupload
fileupload.label.single=Add file...
fileupload.label.multi=Add files...
fileupload.description.filesize=Maximum file size is: {0}
fileupload.description.extension=Allowed file extensions are: {0}
fileupload.validation.extension=File type not allowed
fileupload.validation.filesize=File is too large
fileupload.status.succes=File(s) uploaded successfully
fileupload.status.failed=Upload failed because the following file(s) do not meet all conditions:

Multiple File Upload

To build this the functionality of multiple file upload the following steps have to be taken.:

1. Define a connection name as described earlierbefore.

2. Create an entity, e.g. 'File', in your model.
3. Create at least one attribute: File.Id. For convenience add also File.Name, File.Type and File.Size.
4. Create an exposed flow.
5. Create a page which is put in the flow and is connected.

6. Create a container of type AQ_File_Upload ( and put place it on the page ) with the following parameters:

   Parameter	Value	Comments
   Connection	<connection name>
   Persistence	Temporary
   Mode	Multiple files
   FileID	File.Id
   FileName	File.Name
   FileType	File.Type
   FileSize	File.Size

7. Create a container of type AQ_InstanceSelectorPlus.
   1. Let the containment be: File.Id, File.Name, File.Type, File.Size, all of them read-only
   2. Let the parameters be: Parameter 'entity' should be 'File'.
8. Let the instance selector container be the second container on the page.
9. The upload container is ready to use.

...

It is possible to extend this list with some custom meta data fields. These can be created and updated by using the AQ_File_UpdateMetaData service.

Download File

To get the download file container work, first create a text item with the name 'DownloadText' and enter some text, e.g. Download.

Create a AQ_File_Download container and add the following parameters:

...

To be able to delete a file you need a service for that. Create a new service of type 'AQ_File_Delete'. Enter the following parameters:

...

Move a File

By using the AQ_File_Move it is possible to move a file from one connection to another connection. This could be handy useful when uploading on default to memory by default, adding some meta data and storing it on the file system afterwards. This service can be used by entering the following parameters.

...

There could be a need for directly triggering a flow when uploading a file. This could be handy useful when calling some services for setting information.

...

• Add an event, e.g. 'AutomaticUpload'.
• Add this event to the expected events of the AQ_File_Upload in the tab 'Events'.
• Connect a service in the flow which is connected to this event.

Everytime Every time a new file is uploaded, this exit event will be taken.
