Real-time Validation in livewire

 Livewire gives you the opportunity to make real-time validation of your form.

let me show you how it works.

Inside your components class

namespace App\Http\Livewire\Tuts;

use Livewire\Component;

class ContactForm extends Component
{
    public $name;
    public $email;
    public $message;
    protected $rules = [
        'name' => ['required'],
        'email' => ['required','email'],
        'message' => ['required', 'max:10']
    ];
    public function render()
    {
        return view('livewire.tuts.contact-form')->layout('layouts.app')->slot('main');
    }
    public function updated($propertyName)
    {
        $this->validateOnly($propertyName);
    }

    public function submit(){
        $this->validate();
        dd('submitted');
    }
}

Inside your view

<div class="col-lg-12 ">
    <div class="container">
        <div class="row col-lg-8 m-auto">
            <div class="col bg-gray rounded-lg py-8 px-4">
                {{$name}}
                <form wire:submit.prevent="submit">
                    <h1 class="h2">Contact Us Form</h1>
                    <div class="form-group">
                        <label>Name</label>
                        <input type="text" wire:model="name" class="form-control" />
                     @error('name') <span class="error text-danger">
                     {{ $message }}</span> @enderror
                    </div>
                    <div class="form-group">
                        <label>Email</label>
                        <input type="email" wire:model="email"
                        class="form-control" />
                     @error('message') <span class="error text-danger">
                    {{ $message }}</span> @enderror
                    </div>
                    <div class="form-group">
                        <label>Message</label>
                        <textarea class="form-control" wire:model="message">
                        </textarea>
                     @error('message') <span class="error text-danger">
                     {{ $message }}</span> @enderror
                    </div>
                  <div class="form-group">
                     <button type="submit" class="btn btn-primary btn-sm">
                      Submit
                    </button>
                  </div>    
                </form>
               
            </div>
        </div>
    </div>
</div>
