title: session variable getting null or lost when I didn't update information
body: <p>In my page, I have:</p>
  
  <pre><code>1. Registration Page
  2. Login Page
  3. Successful Registration Page
  4. Referral Form
  </code></pre>
  
  <p>In my registration Page, User can register through this.</p>
  
  <p>In my Log-in page, I have two types of user, <strong>Applicant</strong> and <strong>Employee</strong></p>
  
  <p>In my Successful Registration Page, there is a button directs to Referral Form.</p>
  
  <p>In my Referral Form Page, I have a modal there to update referral information provided by the user during the registration.
  The following information are: </p>
  
  <pre><code> Referrer ID
   Fullname
   Current Position
   ContactID
   Email Address
   MObile Number
   Member Since
  </code></pre>
  
  <p>If you created an account on my page, either you are a <strong>Applicant</strong> or <strong>Employee</strong>, if you successfully register, my <em>successful registration page</em> will prompt to you and once you have click the button going to <em>Referral Form</em> The following information will be displayed to your referral information based on you supplied during the registration.</p>
  
  <p>If you register as an <strong>Applicant</strong>, your <code>Referrer ID</code> is always set into <em>0</em> and you may edit it through <em>Referral Form Page</em>
  or if you register as an <strong>Employee</strong>, your <code>Referrer ID</code> is based on you provide during the registration.
  <em>Example:</em></p>
  
  <pre><code>Referrer ID (Allowed to edit if you register as an applicant)
  Fullname Sherlock Holmes
  Current Position (This has no value and may be edit once you created an account)
  ContactID CON12344
  Email Address SherlockHolmes@gmail.com
  MObile Number +987676758857

  <p>Here's my problem that I encounter.</p>
  
  <p>I created an account and Successful registration page prompt to me, and I click the button going to <em>Referral Form Page</em> to edit my information. I edit it and Log-it out and try to relog-in, My Information updated and now reflecting on my  Information. It works well.</p>
  
  <p><strong>But</strong>
  When I created an account and promt successful registration page and click the button going to <em>Referral Form Page</em>, If I did not edit my information and tried to log it out and try to re-login, my information becomes having all null values. Like this,</p>
  
  <pre><code> Referrer ID 0
   Fullname
   Current Position
   ContactID
   Email Address
   MObile Number
   Member Since
  </code></pre>
  
  <p>Which was incorrect because even I did not edit my information, my information should just becomes like this.</p>
  
  <pre><code> Referrer ID 0(You can edit it)
   Fullname Sherlock Holmes
   Current Position (You can edit it)
   ContactID CON12345678
   Email Address sherlockholmes@gmail.com (You can edit it)
   MObile Number +93456789 (You can edit it)

  <p>Do I have problem passing the session variable when the user didn't fill up the information after they created an account?
  If user edit and fill up all information and try to re-logout and re-login. It seems okay and works.
  But after user created an account, and If I didn't edit the information and log it out and try to re-login, it does not reflect the values.
  I won't reflect the value of session when I didn't update the information if  I logout and try to re-login. Thanks</p>
