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
       App\Providers\CustomAuthProvider::class,
       ...
   ],
   

3. Create CustomAuthProvider.php inside folder app\Providers

   namespace App\Providers;
   
   use Illuminate\Support\Facades\Auth;
   
   use App\Providers\CustomUserProvider;
   use Illuminate\Support\ServiceProvider;
   
   class CustomAuthProvider extends ServiceProvider {
   
       /**
        * Bootstrap the application services.
        *
        * @return void
        */
       public function boot()
       {
           Auth::provider('custom', function($app, array $config) {
          // Return an instance of             Illuminate\Contracts\Auth\UserProvider...
           return new CustomUserProvider($app['custom.connection']);
           });
       }
   
       /**
        * Register the application services.
        *
        * @return void
        */
       public function register()
       {
           //
       }
   }
   

4. Create CustomUserProvider.php also inside folder app\Providers

   <?php
   
   namespace App\Providers;
   use App\User; use Carbon\Carbon;
   use Illuminate\Auth\GenericUser;
   use Illuminate\Contracts\Auth\Authenticatable;
   use Illuminate\Contracts\Auth\UserProvider;
   use Illuminate\Support\Facades\Hash;
   use Illuminate\Support\Facades\Log;
   
   class CustomUserProvider implements UserProvider {
   
   /**
    * Retrieve a user by their unique identifier.
    *
    * @param  mixed $identifier
    * @return \Illuminate\Contracts\Auth\Authenticatable|null
    */
   public function retrieveById($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 $token
    * @return \Illuminate\Contracts\Auth\Authenticatable|null
    */
   public function retrieveByToken($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  \Illuminate\Contracts\Auth\Authenticatable $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 \Illuminate\Contracts\Auth\Authenticatable|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  \Illuminate\Contracts\Auth\Authenticatable $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 Illuminate\Foundation\Auth\User.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 Illuminate\Database\Eloquent\Model.php

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

Answer 2

A custom Auth::attempt() doesn't work for me by changing the model in auth.php like this:

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\Person::class,
    ],
], 

If I try to authenticate a Person via custom column names in Auth::attempt:

if (Auth::attempt(['persUsername' => $request->user, 'persPassword' => $request->pass])) {
    return redirect()->intended('/');
}

I get the same error:

ErrorException in EloquentUserProvider.php line 112: Undefined index: password

But I can authenticate a Person like this:

$person = Person
    ::where('persUsername', $request->user)
    ->where('persPassword', $request->pass)
    ->first();

if (! is_null($person)) {
    if ($person->persUsername === $request->user && $person->persPassword === $request->pass) {
        Auth::login($person, false);
        return redirect()->intended('/');
    }
}

But that's not the way it should be, I guess.

In the mentioned File (EloquentUserProvider.php), I see 'password' is hardcoded.

public function retrieveByCredentials(array $credentials)
{
    $query = $this->createModel()->newQuery();

    foreach ($credentials as $key => $value) {
        if (! Str::contains($key, 'password')) {
            $query->where($key, $value);
        }
    }

    return $query->first();
}

public function validateCredentials(UserContract $user, array $credentials)
{
    $plain = $credentials['password'];

    return $this->hasher->check($plain, $user->getAuthPassword());
}

So there is actually no way to use a custom column name for passwords the easy way?

Answer 3

This is easy simply use the desired column names in Auth::attempt()/method like so:

if (Auth::attempt(['st_username' =>$username,'st_password' => $password])) { 
    // Authentication passed... 
    return redirect()>intended('dashboard'); 
}

Updated: If you also wish to change default authentication table which is users by default or change the model name or path App\User by default, you can find these settings in config\auth.php

/*
|--------------------------------------------------------------------------
| Authentication Table
|--------------------------------------------------------------------------
|
| When using the "Database" authentication driver, we need to know which
| table should be used to retrieve your users. We have chosen a basic
| default value but you may easily change it to any table you like.
|
*/

//'table' => 'users', 
'table' => 'new_tables_for_authentication',



/*
|--------------------------------------------------------------------------
| Authentication Model
|--------------------------------------------------------------------------
|
| When using the "Eloquent" authentication driver, we need to know which
| Eloquent model should be used to retrieve your users. Of course, it
| is often just the "User" model but you may use whatever you like.
|
*/

//'model' => App\User::class,
'model' => App\Models\User::class,
