<form id="photo-form" name="upload" enctype="multipart/form-data" method="post" action="/upload">
				Виберіть зображення, які бажаете загрузити.
			<input id="files-field" type="file" multiple="multiple" />
			<input type="submit">
			<a class="send-files button tiny small-4">Загрузити</a>
	</form>

(function(){
	$('body').on('click', '.send-files', function() {

		var formData = new FormData(),
			items = $('#files-field')[0].files
			formData.append('file', items);

		$.ajax({
			type: "POST",
			url: '/upload',
			data: formData,
			processData: false,
			success: function(){
				//window.location.href = '/';
			}
		});
	})
}());

upload.post('/', function(req, res) {

	var form = new formidable.IncomingForm();
		form.uploadDir ='..//public/images';
		form.keepExtensions = false;
		form.type = 'multipart/form-data';
		form.multiples = true;

		form.on('error', function(err) {
	        console.log(err);
	    });

		console.log(form);

		form.on('end', function(fields, files) {
			console.log('end')
		});

	    form.parse(req, function(err, fields, files) {
	      console.log(err, fields, files)
	    });

   		res.end();
	
});
