it will work well in localhost, when ever i deploy it on to server, registration form doesnot responding??

here is my code var express = require(‘express’), http = require(‘http’), path = require(‘path’), hash = require(‘./pass’).hash; var moment = require(‘moment’); var bcrypt = require(‘bcrypt’); var app = express(); var methodOverride = require(‘method-override’); var mysql = require(‘mysql’); connection.connect(function(err){ if(!err) { console.log(“Database is connected … nn”); } else { console.log(“Error connecting database … nn”); } }); /* Middlewares and configurations / app.configure(function () { app.use(express.bodyParser()); app.use(express.cookieParser('Authentication Tutorial ')); app.use(express.session()); app.use(methodOverride(function(req, res){ if (req.body && typeof req.body == ‘object’ && ‘_method’ in req.body) { var method = req.body._method; delete req.body._method; return method; } })); app.use(express.static(path.join(__dirname, ‘public’))); app.set(‘views’, __dirname + ‘/views’); app.set(‘view engine’, ‘ejs’); }); var connection = mysql.createConnection({ host : ‘hostss’, user : ‘user’, password : 'password’, database : ‘db’ }); app.use(function (req, res, next) { var err = req.session.error, msg = req.session.success; delete req.session.error; delete req.session.success; res.locals.message = ‘’; if (err) res.locals.message = ‘<p class=“msg error”>’ + err + ‘</p>’; if (msg) res.locals.message = ‘<p class=“msg success”>’ + msg + ‘</p>’; next(); }); /* Helper Functions */

function user_exits(req, res, next) { var username= req.body.username; connection.query(“SELECT * FROM user WHERE username =?”,[username],function (error, results, fields) { if (error) { console.log(error); res.send(“fail internal error”+“\r\n”); } if (results.length >0) { console.log(‘User is Already Exists’); res.send(“fail user already exists”+“\r\n”);

} else {

    console.log('No user Available oN that name, U can insert it');
    next();

}

}); }

/* Routes */ app.get(“/”, function (req, res) {

    res.render("index", { moment: moment });

});

app.get(“/signup”, function (req, res) { res.render(“signup”,{ moment: moment });

});

app.post(“/signup”,user_exits,function (req, res){ bcrypt.hash(req.body.password, 5, function( err, bcryptedPassword) {

var users={ “username”:req.body.username, “email”:req.body.email, “password”:bcryptedPassword,

} console.log(users); connection.query(‘INSERT INTO user SET ?’,users, function (error, results, fields) { if (error) { console.log(“error ocurred”,error); res.send({ “code”:400, “failed”:“error ocurred” }); }else{ console.log('The solution is: ', results); res.send({ “code”:200, “success”:“user registered sucessfully” }); } }); });

});

app.get(“/login”, function (req, res) { res.render(“login”,{ moment: moment }); });

app.post(“/login”,function (req, res) { var sess = req.session; var username= req.body.username; var password = req.body.password; connection.query(‘SELECT * FROM user WHERE username = ?’,[username], function (error, results, fields) { if (error) { console.log(error); }else{ if(results.length >0){ bcrypt.compare(password, results[0].password, function(err, doesMatch){ if (doesMatch){ req.session.userId = results[0].id; req.session.user = results[0]; console.log(results[0].id); res.redirect(‘/profile/’+results[0].id); }else{ res.send({ “code”:204, “success”:“Email and password does not match” }); } }); } else{ console.log(“fine”); } } }); }); but when i upload it on digitalocean server the form is not working?? please developer help me to fix that problem…
