Uploading by ORAF/OROF

Explanation

DEXTUploadX5 supports four modes for file upload operation.

• ORAF (default): Sends all files to be uploaded in one request. When the upload is completed, the response data becomes one.
• OROF: Requests are made as many as the number of files to be uploaded. When uploading is completed, response data is generated by the number of files.
• EXTS: Same as OROF, but for large uploads, used when individual or all files are larger than 2 GB in size. (See the example of uploading a large file).
• AWSS3: Used to upload files to Amazon S3. (See the Amazon S3 file upload example.)

var dx = dx5.get("component-id");

// Set the upload mode to ORAF, OROF, EXTS, AWSS3. 
dx.setUploadMode("ORAF");

// Uploading all local files. 
dx.upload("AUTO");
// Uploading all selected local files. 
dx.upload("SELECTED");
// Uploading all checked local files. 
dx.upload("CHECKED");

If you upload a file by ORAF, you can get the uploaded file at once on the server side.

# Server-side					
...
dextnj = new FileUpload(request, env);  

// Store all the file data part from the data sent from the client as a temporary file. 
// Temporary save location is set by Environment # setTempRepository method.
dextnj.prepare();  

// You can call them one by one using the FileUpload # getFileItem method, but you can get the collection object using the getFileItems method.
List<FileItem> items = dextnj.getFileItems();

// Get the uploaded mode file at once using the same loop statement for.
FileItem file = null;
for (int i = 0; i < items.size(); i++) {
	file = items.get(i);
	if (file.isEmpty() == false) {
		file.save();
		...
	}
}
...

When uploading a file by OROF, the server side requests one request per file.

# Server-side					
...
dextnj = new FileUpload(request, env);		
	
dextnj.prepare();

// Because it is OROF, only one file form element is passed to the server.
FileItem file = dextnj.getFileItem(0);
if (file.isEmpty() == false) {
	file.save();
	...
}
...

Clients can change the upload method with just a few settings, but the server side code can have a completely different configuration depending on the uploading method.
