Laravel 7 Custom Validation Error Messages Example

Step 1: Install Laravel Application
Step 2: Setup Database Credentials
Step 3: Run Migration Command

Step 4: Create Route
Step 5: Generate Controller By Command
Step 6: Create the blade view

Step 7: Run Development Server

Step 1: Install Laravel Application

First of all we need to create a fresh laravel project, download and install Laravel using the below command

composer create-project --prefer-dist laravel/laravel Blog

1	composer create-project --prefer-dist laravel/laravel Blog

Step 2: Setup Database Credentials

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql 
DB_HOST=127.0.0.1 
DB_PORT=3306 
DB_DATABASE=here your database name here
DB_USERNAME=here database username here
DB_PASSWORD=here database password here

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=here your database name here

DB_USERNAME=here database username here

DB_PASSWORD=here database password here

Step 3: Run Migration Command

Now, in this step we will create model and migration file. Please run the following command:

php artisan migrate

1	php artisan migrate

Step 4: Create Routes

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

Route::get('form', 'CustomErrorController@create');
Route::post('store', 'CustomErrorController@store');

1 2	Route::get('form', 'CustomErrorController@create'); Route::post('store', 'CustomErrorController@store');

Step 5: Generate Controller By Command

Now, lets create a controller named CustomErrorController using command given below –

php artisan make:controller CustomErrorController

1	php artisan make:controller CustomErrorController

Now, go to app/Http/Controllers/CustomErrorController.php and put the following code into your controller file:

app/Http/Controllers/CustomErrorController.php

namespace App\Http\Controllers;
   
use Illuminate\Http\Request;
use App\User;
   
class CustomErrorController extends Controller
{
    public function create()
    {
        return view('form');
    }
   
    public function store(Request $request)
    {
        $request->validate(
            [
                'name' => 'required',
                'password' => 'required|min:5',
                'email' => 'required|email|unique:users'
            ], 
            [
                'name.required' => 'Name is required',
                'password.required' => 'Password is required'
            ]
          );
    
        $input = $request->all();
        $input['password'] = bcrypt($input['password']);
        $user = User::create($input);
     
        return back()->with('success', 'User created successfully.');
    }
}

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\User;

class CustomErrorController extends Controller

{

public function create()

{

return view('form');

}

public function store(Request $request)

{

$request->validate(

[

'name' => 'required',

'password' => 'required|min:5',

'email' => 'required|email|unique:users'

[

'name.required' => 'Name is required',

'password.required' => 'Password is required'

]

);

$input = $request->all();

$input['password'] = bcrypt($input['password']);

$user = User::create($input);

return back()->with('success', 'User created successfully.');

}

Step 6: Create Blade View

Now, we will go to resources/views folder and create a blade view file name from.blade.php and put the following code into your file:

resources/views/form.blade.php

            {{ Session::get('success') }}
            @php
                Session::forget('success');
            @endphp
        </div>
        @endif
    
        <form method="POST" action="{{ route('store') }}">
   
            @csrf
   
            <div class="form-group">
                <label>Name:</label>
                <input type="text" name="name" class="form-control" placeholder="Name">
                @if ($errors->has('name'))
                    <span class="text-danger">{{ $errors->first('name') }}</span>
                @endif
            </div>
    
            <div class="form-group">
                <label>Password:</label>
                <input type="password" name="password" class="form-control" placeholder="Password">
                @if ($errors->has('password'))
                    <span class="text-danger">{{ $errors->first('password') }}</span>
                @endif

                <input type="text" name="email" class="form-control" placeholder="Email">
                @if ($errors->has('email'))
                    <span class="text-danger">{{ $errors->first('email') }}</span>
                @endif
            </div>
    
            <div class="form-group">
                <button class="btn btn-success btn-submit">Submit</button>
            </div>
        </form>
