FecRO跨境商城，后台设置支持游客订单无效BUG

文件路径：fecshop/addons/fecmall/fecro/app/appfront/modules/Checkout/controllers/OnepageController.php

问题是init方法中$guestOrder变量未赋值，添加$guestOrder = Yii::$app->store->get('order', 'guestOrder');

public function init()
{
	parent::init();
	$guestOrder = Yii::$app->store->get('order', 'guestOrder');
	if($guestOrder != Yii::$app->store->enable && Yii::$app->user->isGuest){
		$checkoutOrderUrl = Yii::$service->url->getUrl('checkout/onepage/index');
		Yii::$service->customer->setLoginSuccessRedirectUrl($checkoutOrderUrl);

		return Yii::$service->url->redirectByUrlKey('customer/account/login');
	} 

}
