if (!empty($_POST['progress'])) {
	if(Input::exists()) {
		if(Token::check(Input::get('token'))) {
			$adminprogress = Input::get('admin');
			$adminidprogress = Input::get('adminid');
			$memberprogress = Input::get('member');
			$projectprogress = Input::get('project');
			$statusprogress = Input::get('status');
			$timestamp = date('Y-m-d H:i:s');
			
			$progressupdate = DB::getInstance()->insert(progress, array(
				'admin' => $adminprogress,
				'adminid' => $adminidprogress,
				'member' => $memberprogress,
				'project' => $projectprogress,
				'status' => $statusprogress,
