How can i login with single role if user have multiple role assigned in laravel?

问题

I have a use case that a user having multiple role but want to login user with a single role at a time and give the rights of respective role. For example a user have employee,manager & finance manager role and each role has its own permissions/rights. So, now i want the system ask for role selection when user trying to login in the system and on the basis of selection it would authenticate .

Laravel 5.4

Zizaco/entrust 1.3.x

TIA.

You need multiple guard function for different user roles. you can edit that in config/auth.php

During sign in you can use a drop down menu. Based on that input you can define different guard in your controller. Your code can be something like the following;

if (request('role')=='admin')
   if(Auth::guard('admin')->attempt($credentials)){
       // your code to login
   }

else if (request('role')=='user')
   if(Auth::guard('user')->attempt($credentials)){
       // your code to login
   }

For more information on authentication you can view the documentation
