display file name in a single array in multer using nodejs-CodePudding

here is a part of my code of multer using nodejs

const storageEngine = multer.diskStorage({
    destination: (req, file, cb) => {
        cb(null, './Images')
        const Files = [file.originalname]
        console.log(Files)
    },
    filename: (req, file, cb) => {
        cb(null, file.originalname)
    }
})

the console log of the above code is this:

['image.png']
['image2.png']
['image3.png]

so i want all file names to be in one array to be posted in mysql in one go as i do not want to send multiple request to mysql as there are numerous amount of images.

so all i want is the file names to be present in one single array like this:

['image.png', 'image2.png', 'image3.png']

CodePudding user response：

The destination event that you use is invoked once per uploaded file, so you cannot use it to collect all file names.

Assuming you have an input field <input type="file" multiple name="upload">, you can instead use

app.use(storageEngine.array("upload"))
.use(function(req, res, next) {
  console.log(req.files.map(file => file.originalname));
  next();
});
