public class FileItem
extends CanvasItem

Binary data interface for use in DynamicForms. Allows users to select a single file for upload. In read-only mode (canEdit:false) displays the contents of "imageFile" fields.

Editable mode

See the Upload Overview for information on using this control.

Read-only mode

Displays one of two UIs, according to the value of showFileInline. If showFileInline is false, this Item displays the View and Download icons and the filename. Otherwise, it streams the image-file and displays it inline.

Overrides:

setMultiple

public void setMultiple(Boolean multiple)

When true, allow the file-selection dialog shelled by the browser to select multiple files.

Support is not full-cycle at the server - that is, there are server APIs for retrieving each file that was uploaded, but no built-in support for storing multiple files against a single DataSource field. However, you can write custom server DMI code to do something with the files - for instance, you could create multiple new DataSource records for each file via a server DMI like this below:

     String fileNameStr = (String)dsRequest.getValues().get("image_filename").toString();
 
     String[] fileNames = fileNameStr.split(", ");
     List files = dsRequest.getUploadedFiles();
 
     for (int i = 0; i < files.size(); i++) {
         ISCFileItem file = (ISCFileItem)files.get(i);
         InputStream fileData = file.getInputStream();
         DSRequest inner = new DSRequest("mediaLibrary", "add");
         Map values = new HashMap();
         values.put("title", dsRequest.getValues().get("title"));
         values.put("image", fileData);
         values.put("image_filename", fileNames[i]);
         values.put("image_filesize", file.getSize());
         values.put("image_date_created", new Date());
         
         inner.setValues(values);
         inner.execute();
     }
     
     DSResponse dsResponse = new DSResponse();
     
     dsResponse.setStatus(0);
 
     return dsResponse;
