title: how to do real time notification in codeigniter
body: <p>I have one requirement form in my application. So whenever user insert details in requirement form, after submit the mail will go to the particular vendor with link. When vendor clicks on that link, the link will redirect to the login page. After login then vendor gets redirected to vendor dashboard.</p>
  
  <p>So what i want to do is, when ever user insert something in the requirement, the notification will go to the particular vendor dashboard after login like "you have one new requirement" like that</p>
  
  <p>I have no idea on how to do this</p>
