Parse form value with formidable to filename

Formidable's end callback doesn't take any parameters, but I'm not sure you even need to call it if you're using the parse callback. I think what you're looking for is something like this:

var fs = require('fs');app.post('/uploads', function(req, res, next) {    var form = new formidable.IncomingForm();    form.parse(req, function(err, fields, files) {        if (err) next(err);        // TODO: make sure my_file and project_id exist            fs.rename(files.my_file.path, fields.project_id, function(err) {            if (err) next(err);            res.end();        });    });});

You would need to listen for the end() event if you chose not to use the parse callback, like this:

new formidable.IncomingForm().parse(req)    .on('file', function(name, file) {        console.log('Got file:', name);    })    .on('field', function(name, field) {        console.log('Got a field:', name);    })    .on('error', function(err) {        next(err);    })    .on('end', function() {        res.end();    });

Client side script:

    //Upload the file    var fd = new FormData();    //Take the first selected file    fd.append("dbDocPath", 'invoices/' + file.name);    fd.append("file", file);    $http({            method: 'POST',            url: $rootScope.apiUrl + 'uploadDocToServer',            data: fd,            headers: {                'Content-Type': undefined            },            //prevents serializing payload.  don't do it.            transformRequest: angular.identity,        }).success(function (response) {           if (response.success) {           }   })

Server side script:

var fileDir = path.join(__dirname, '/../uploads');// create an incoming form objectvar form = new formidable.IncomingForm();var dbDocPath = '';form.parse(req)        .on('field', function (name, field) {            //console.log('Got a field:', field);            //console.log('Got a field name:', name);            dbDocPath = field;        })        .on('file', function (name, file) {            //console.log('Got file:', name);            // specify that we want to allow the user to upload multiple files in a single request            //form.multiples = true;            // store all uploads in the /uploads directory            form.uploadDir = fileDir;            fs.rename(file.path, path.join(form.uploadDir, file.name));            // every time a file has been uploaded successfully,            // rename it to it's orignal name            var bucket = new AWS.S3();            //console.log(dbDocPath);            var params = {                Bucket: DocsConfig.bucketName,                Key: dbDocPath,                Body: fs.createReadStream(path.join(form.uploadDir, file.name)),                ACL: 'public-read'            };            bucket.putObject(params, function (perr, pres) {                if (perr) {                    //console.log("Error uploading data: ", perr);                } else {                    fs.unlinkSync(path.join(form.uploadDir, file.name));                    //console.log("Successfully uploaded data", pres);                }            });        })        .on('error', function (err) {            res.send({'success': false, error: err});        })        .on('end', function () {            res.send({'success': true});        });// parse the incoming request containing the form data//form.parse(req);

Just keep one thing in mind that the sequence of sending parameters to formData() should be same as mentioned in above code as file upload needs path to upload to the destiny.
