Laravel 5.8 form validation example

Today's topic how to create form validation with error messages in php laravel 5.8. we can simply create form validation in controller side and display error messages in blade file on client side validation message.

you can easily use laravel 5.8 default validation rules like form validation number, form validation nullable, form validation max length, form validation greater than, form validation float, form validation file, form validation email, form validation dropdown, form validation date_format, form validation date, form validation decimal, form validation confirmed etc you can use with laravel 5.8.

Here, i am going to show you very simple example of form validation so, you can simply use in your laravel 5.8 project.

Create Routes:

Here we are learning simple and easy example of validation in laravel 5.8 so just add following both route in your web.php file.

routes/web.php


Route::get('user/create', 'HomeController@create');
Route::post('user/create', 'HomeController@store');

Create HomeController:

Now we will add two controller method, one will just display blade file with get request, and another for post request, i write validation for that, so simply add both following method on it.

app/Http/Controllers/HomeController.php


<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\User;
  
class HomeController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('createUser');
    }
  
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    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.');
    }
}

Create Blade File:

now here we will create createUser.blade.php file and here we will create bootstrap simple form with error validation message. So, let's create following file:

resources/views/createUser.blade.php


<!DOCTYPE html>

<head>
    <title>Laravel 5.8 form validation example</title>

<body>
    <div class="container">
  
        <h1>Laravel 5.8 form validation example</h1>
   
        @if(Session::has('success'))
        <div class="alert alert-success">
            {{ Session::get('success') }}
            @php
                Session::forget('success');
            @endphp
        </div>
        @endif
   
        <form method="POST" action="{{ url('user/create') }}">
  
            {{ csrf_field() }}
  
            <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
            </div>
    
            <div class="form-group">
                <strong>Email:</strong>
                <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>
    </div>
</body>
