var express = require('express'), app = express(), formidable = require('formidable'), util = require('util'), fs = require('fs-extra'), bodyparser=require('body-parser'), qt = require('quickthumb'), path = require('path'); var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/db'); var Images = require('./model.js'); app.use(qt.static(__dirname + '/')); app.use(bodyparser()); app.set('view engine','ejs'); app.post('/upload',function (req, res){ var form = new formidable.IncomingForm(); form.parse(req, function(err, fields, files) { }); form.on('field',function(name,value){ }); form.on('end', function(fields, files) { for(var x in this.openedFiles) { //Images is my model var img = new Images(); var temp_path = this.openedFiles[x].path; /* The file name of the uploaded file */ var file_name = this.openedFiles[x].name; //console.log('file '+file_name); img.size = this.openedFiles[x].size; img.type = this.openedFiles[x].type; /* Location where we want to copy the uploaded file */ var new_location = 'uploads/'; console.log(img.nam=new_location+file_name); img.save(function(err,imgobj) { if (err) throw err; }); //to copy the file into a folder fs.copy(temp_path, new_location + file_name, function(err) { if (err) { console.log(err); } });//fscopy }//for loop });//form end res.send('Done!!'); });//post app.listen(3000); console.log('started server');
