Help with Formidable

[Phil Daws]

Hello,

I am attempting to write my first app that simply allows a file to be uploaded. When I click on the submit button the browser appears to start to post but just sits there. The app code I am using is:

app.post('/upload', function(request, response) {

  

  var form = new formidable.IncomingForm();

  

  form.uploadDir = __dirname + '/uploads';

  logger('Upload dir = ' + form.uploadDir);

 

  form.on('file', function(field, file) {

    logger('Receving file - ' + file.name);

    fs.rename(file.path, form.uploadDir + "/" + file.name);

  });

  form.on('error', function(err) {

    logger("an error has occured with form upload");

    logger(err);

    request.resume();

  });

  form.on('progress', function(bytesReceived, bytesExpected) {

    logger('Received: ' + bytesReceived + ' Expected: ' + bytesExpected);

  });

  form.on('aborted', function(err) {

    logger("user aborted upload");

  });

  form.on('end', function() {

    logger('upload completed');

  });

    

  form.parse(request, function() {

    response.render('/upload');

  });

}); 

and in the jade template I have:

h1= title

p #{title}

form(action="/upload", method="post", enctype="multipart/form-data")

  span

    input(class="uploadselection", type="file",   name="uploadFile")

    input(class="uploadbutton",    type="button", value="Upload", name="upload", onClick="submit();")

    input(class="uploadbutton",    type="button", value="Cancel Upload", name="cancel")

What I see on the console is:

9 Feb 17:28:10 - [nodemon] starting `node app.js`

   info  - socket.io started

Express server listening on port 8080 in development mode

9 Feb 17:28:14 - Connect from 127.0.0.1

9 Feb 17:28:19 - Disconnection from 127.0.0.1

9 Feb 17:28:19 - Upload dir = /home/uxbod/Development/nodeapps/fileupload/uploads

What am missing please ? I do not even see any data received :(

I have studied the example upload.js and change my code slightly based on that but it still just hangs when I post :( If I try the example code that works fine. Must be missing something silly :(

app.get('/upload', routes.upload);

app.post('/upload', function(request, response) {

  var form = new formidable.IncomingForm(), files = [], fields = [];

  form.uploadDir = __dirname + '/uploads';  

  

  logger('Processing form');

  form

  

  .on('file', function(field, file) {

    logger('Receving file - ' + file.name);

    files.push([field, file]);

  })

  .on('field', function(field, value) {

    console.log(field, value);

    fields.push([field, value]);

  })

  .on('error', function(err) {

    logger("an error has occured with form upload");

    logger(err);

    request.resume();

  })

  .on('progress', function(bytesReceived, bytesExpected) {

    logger('Received: ' + bytesReceived + ' Expected: ' + bytesExpected);

  })

  .on('aborted', function(err) {

    logger("user aborted upload");

  })

  .on('end', function() {

    logger('-> upload done');

    result.writeHead(200, {'content-type': 'text/plain'});

    result.write('received fields:\n\n ' + util.inspect(fields));

    result.write('\n\n');

    result.end('received files:\n\n ' + util.inspect(files));

  });   

  form.parse(request);

});

if you're using bodyParser read the bottom of this:
http://www.senchalabs.org/connect/middleware-bodyParser.html
it will otherwise handle multipart for you

Perfect, thank you :)
