php - How to get login with different database table column name in Laravel 5.2?

Question

I have to implement login functionality in Laravel 5.2. I have successfully done so using the official Laravel documentation except that I do not know how to authenticate the user using different database table column names, namely st_usernameand st_password.

I have searched the Internet for clues but to no avail. I don't know which class I need to use (like, use Illuminate.......) for Auth. If any one knows the answer, please let me know.

Here is my code:

Login View

@extends('layouts.app')
@section('content')

<div class="contact-bg2">
    <div class="container">
        <div class="booking">
            <h3>Login</h3>
            <div class="col-md-4 booking-form" style="margin: 0 33%;">
                <form method="post" action="{{ url('/login') }}">
                    {!! csrf_field() !!}

                    <h5>USERNAME</h5>
                    <input type="text" name="username" value="abcuser">
                    <h5>PASSWORD</h5>
                    <input type="password" name="password" value="abcpass">

                    <input type="submit" value="Login">
                    <input type="reset" value="Reset">
                </form>
            </div>
        </div>
    </div>

</div>
<div></div>

Answer 1

I searched a lot how to customize Laravel 5.2 authorisation form and this is what is working for me 100%. Here is from bottom to top solution.

This solution is originally from here: https://laracasts.com/discuss/channels/laravel/replacing-the-laravel-authentication-with-a-custom-authentication

but i had to make couple changes to make it work.

My web app is for the DJs so my custom column names are with 'dj_', for example name is dj_name

1. config/auth.php

   // change this
   'driver' => 'eloquent',
   // to this
   'driver' => 'custom',
   

2. in config/app.php add your custom provider to the list ...

   'providers' => [
       ...
       // add this on bottom of other providers
       AppProvidersCustomAuthProvider::class,
       ...
   ],
   

3. Create CustomAuthProvider.php inside folder appProviders

   namespace AppProviders;
   
   use IlluminateSupportFacadesAuth;
   
   use AppProvidersCustomUserProvider;
   use IlluminateSupportServiceProvider;
   
   class CustomAuthProvider extends ServiceProvider {
   
       /**
        * Bootstrap the application services.
        *
        * @return void
        */
       public function boot()
       {
           Auth::provider('custom', function($app, array $config) {
          // Return an instance of             IlluminateContractsAuthUserProvider...
           return new CustomUserProvider($app['custom.connection']);
           });
       }
   
       /**
        * Register the application services.
        *
        * @return void
        */
       public function register()
       {
           //
       }
   }
   

4. Create CustomUserProvider.php also inside folder appProviders

   <?php
   
   namespace AppProviders;
   use AppUser; use CarbonCarbon;
   use IlluminateAuthGenericUser;
   use IlluminateContractsAuthAuthenticatable;
   use IlluminateContractsAuthUserProvider;
   use IlluminateSupportFacadesHash;
   use IlluminateSupportFacadesLog;
   
   class CustomUserProvider implements UserProvider {
   
   /**
    * Retrieve a user by their unique identifier.
    *
    * @param  mixed $identifier
    * @return IlluminateContractsAuthAuthenticatable|null
    */
   public function retrieveById($identifier)
   {
       // TODO: Implement retrieveById() method.
   
   
       $qry = User::where('dj_id','=',$identifier);
   
       if($qry->count() >0)
       {
           $user = $qry->select('dj_id', 'dj_name', 'first_name', 'last_name', 'email', 'password')->first();
   
           $attributes = array(
               'id' => $user->dj_id,
               'dj_name' => $user->dj_name,
               'password' => $user->password,
               'email' => $user->email,
               'name' => $user->first_name . ' ' . $user->last_name,
           );
   
           return $user;
       }
       return null;
   }
   
   /**
    * Retrieve a user by by their unique identifier and "remember me" token.
    *
    * @param  mixed $identifier
    * @param  string $token
    * @return IlluminateContractsAuthAuthenticatable|null
    */
   public function retrieveByToken($identifier, $token)
   {
       // TODO: Implement retrieveByToken() method.
       $qry = User::where('dj_id','=',$identifier)->where('remember_token','=',$token);
   
       if($qry->count() >0)
       {
           $user = $qry->select('dj_id', 'dj_name', 'first_name', 'last_name', 'email', 'password')->first();
   
           $attributes = array(
               'id' => $user->dj_id,
               'dj_name' => $user->dj_name,
               'password' => $user->password,
               'email' => $user->email,
               'name' => $user->first_name . ' ' . $user->last_name,
           );
   
           return $user;
       }
       return null;
   
   
   
   }
   
   /**
    * Update the "remember me" token for the given user in storage.
    *
    * @param  IlluminateContractsAuthAuthenticatable $user
    * @param  string $token
    * @return void
    */
   public function updateRememberToken(Authenticatable $user, $token)
   {
       // TODO: Implement updateRememberToken() method.
       $user->setRememberToken($token);
   
       $user->save();
   
   }
   
   /**
    * Retrieve a user by the given credentials.
    *
    * @param  array $credentials
    * @return IlluminateContractsAuthAuthenticatable|null
    */
   public function retrieveByCredentials(array $credentials)
   {
   
       // TODO: Implement retrieveByCredentials() method.
       $qry = User::where('email','=',$credentials['email']);
   
       if($qry->count() > 0)
       {
           $user = $qry->select('dj_id','dj_name','email','password')->first();
   
   
           return $user;
       }
   
       return null;
   
   
   }
   
   /**
    * Validate a user against the given credentials.
    *
    * @param  IlluminateContractsAuthAuthenticatable $user
    * @param  array $credentials
    * @return bool
    */
   public function validateCredentials(Authenticatable $user, array $credentials)
   {
       // TODO: Implement validateCredentials() method.
       // we'll assume if a user was retrieved, it's good
   
       // DIFFERENT THAN ORIGINAL ANSWER
       if($user->email == $credentials['email'] && Hash::check($credentials['password'], $user->getAuthPassword()))//$user->getAuthPassword() == md5($credentials['password'].Config::get('constants.SALT')))
       {
   
   
           //$user->last_login_time = Carbon::now();
           $user->save();
   
           return true;
       }
       return false;
   
   
   }
   }
   

5. in App/Http/Controllers/Auth/AuthController.php change all 'name' to 'dj_name' and add your custom fields if you have them...you can also change 'email' to your email column name

6. In IlluminateFoundationAuthUser.php add

   protected $table = 'djs';
   protected $primaryKey  = 'dj_id';
   

7. In App/User.php change 'name' to 'dj_name' and add your custom fields. For changing 'password' column to your custom column name add

   public function getAuthPassword(){
       return $this->custom_password_column_name;
   }
   

8. Now backend is all done, so you only have to change layouts login.blade.php, register.blade.php, app.blade.php...here you only have to change 'name' to 'dj_name', email, or your custom fields... !!! password field NEEDS to stay named password !!!

Also, to make unique email validation change AuthController.php

'custom_email_field' => 'required|email|max:255|unique:users',
to
'custom_email_field' => 'required|email|max:255|unique:custom_table_name',

Also, if you want to make custom created_at an updated_at fields change global variables in IlluminateDatabaseEloquentModel.php

const CREATED_AT = 'dj_created_at';
const UPDATED_AT = 'dj_updated_at';
