meteor - How to ask extra information after login with facebook? -

i have set-up basic meteor application able login facebook. ask valid phone number before creating user. how accomplish in meteor? login workflow :

login-page => click 'login facebook' => user gives permission app => redirect app , ask phone number => create user

i using accounts-facebook , related packages.

thanks

since facebook api doesn't support access user phone, can't extend requestpermission array, ask user_phone.

lets have simple, login facebook button

   meteor.loginwithfacebook({ requestpermissions: ['email']},     function (error) {        if (error) {         return console.log("there error : " error.reason);       }else{         //if there no error, lets redirect new user new template         router.go('/registerform')       }     }); 

now if login successful can redirect user registerform.

register form html

<template name="registerform">   <!-- simple register form asking phone number --> </template> 

js event

 template.registerform.events({     'submit registerform':function(e,t){        //code input value        var userphonenumber = t.$('#phoneinputvalue').val()        meteor.users.update(meteor.userid(),{$set:{'profile.phonenumber':userphonenumber,'profilenumber':true}})      }   }) 

did se boolean value profilenumber? can use template helpers ensure , denied access user if dosnt fill registerform template(just security), can set default on server side using accounts.oncreateuser method this.

accounts.oncreateuser(function(options, user) {        if(!options || !user) {         console.log('error creating user');         return;     } else {         if(options.profile) {             user.profile.userphonenumber = false;         }     }     return user; });
