How To Session Flash Messages in Laravel Livewire 3 Example

Step 1: Create PhotoUpload Component

Now here we will create a Livewire component using their command. So run the following command to create an add more component.

php artisan make:livewire PhotoUpload

Now they created files on both paths:

app/Livewire/PhotoUpload.php
   
resources/views/livewire/photo-upload.blade.php

Now, both files we will update as below for our contact us form.

app/Livewire/PhotoUpload.php

<?php

namespace App\Livewire;

use Livewire\Component;
use Livewire\WithFileUploads;
use App\Models\Image;

class PhotoUpload extends Component
{
    use WithFileUploads;

    public $photo;

    public function render()
    {
        return view('livewire.photo-upload');
    }

    public function submit(){
        $this->validate([
            "photo" => "required|image"
        ]);

        $filepath = $this->photo->store("photos");

        $image = Image::create([
            "title" => "Test",
            "filepath" => $filepath
        ]);

        session()->flash("success", "Image uploaded successfully");

        info($image)
    }
}

resources/views/livewire/photo-upload.blade.php

<div>
    <form wire:submit="submit">

        @if($photo)
            Photo Preview:
            <img src="{{ $photo->temporaryUrl() }}" width="400px"><br/>
        @endif

        @session("success")
            <div class="alert alert-success">
                {{ $value }}
            </div>
        @endsession
        
        <label>Image:</label>
        <input type="file" name="photo" class="form-control" wire:model="photo">
        @error("photo")
        <p class="text-danger">{{ $message }}</p>
        @enderror

        <button class="btn btn-success">Submit</button>

    </form>
</div>

            <div class="card">
                <div class="card-header">{{ __('Counter') }}</div>

                <div class="card-body">
                    <livewire:photo-upload />
                </div>
            </div>
