如何使用 multer 在 nodejs 中从前端的另一个表单值设置上传图像的标题？

Question

I'm Developing an Application where I want to upload images to nodejs server using multer library. I want to entitle my file as "Id_Card_No" value received from Frontend in the same form as receiving the image. And store image's path in MongoDB. For example: Received value from Frontend: id_card_no: 1111-2222222-3 ID Card Image title: Abc.jpg

So I want to replace the title as "1111-2222222-3_IdCard.jpg"

Anyone please help me with the logic to do this??? Currently images are seccessfully being stored in server. I just need help with concatenating the path variable and title. Thanks in advance!

const storage = multer.diskStorage({
    destination: function(req, file, cb) {
        cb(null, 'uploads/');
    },
  
    filename: function(req, file, cb) {
        cb(null, file.fieldname + '-' + Date.now() + path.extname(file.originalname));
    }
});
  
var upload = multer({ storage: storage })
