CSRF (Cross Site Request Forgery) Protetion in Laravel

• CSRF attacks are type of attacks where unauthorized commands are performed on behalf of the authorized user.
• Laravel provides an easy method to block CSRF attacks. 
• You should include a CSRFfield inside the form of HTML. Any HTML forms of method POST, PUT or DELETE should include the CSRF token.
• The Laravel application will automatically generate a CSRF token for each active session managed by the application.

        <form method="POST" action="/post_function">
          {{ csrf_field() }}
          ...
          ...
        </form>
