Livewire Component passing variable to Blade Error

Hello! I have a livewire component called Announcement and this is the code


<?php

namespace App\Http\Livewire;

use Livewire\Component;

class Announcement extends Component
{
    public $message = '';

    public function render()
    {
        return view('livewire.announcement', [
            'message' => 'This is a test announcement!'
        ]);
    }
}

This is my blade file's code in /views/livewire/announcement.blade.php

<div>
    <div>
        <h1>Announcement</h1>
        <h1>{{ $message }}</h1>
    </div>
</div>

I tried a lot of things of why the error message "Undefined variable $message" is always showing but I can't seem to find what solution is applicable.

Solution:

I got it working bro, the solution is I deleted the Announcement Class and its View file and created a new livewire component.

try it like this:

    public function render()
    {
        $this->message = 'This is a test announcement!';

        return view('livewire.announcement');
    }

    public function render()
    {
        $this->message = 'This is a test announcement!';

        return view('livewire.announcement');
    }

I registered the livewire in the AppServiceProvider using this code FilamentView::registerRenderHook( PanelsRenderHook::BODY_START, fn (): View => view('livewire.announcement'), );

Vp•7mo ago

Try like this

fn (): string => Blade::render('@livewire(\'announcement\')')

fn (): string => Blade::render('@livewire(\'announcement\')')

Just check out and I don't have a problem, what I did

// AppServiceProviders
use Filament\Support\Facades\FilamentView;
use Filament\View\PanelsRenderHook;
use Illuminate\Support\Facades\Blade;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        FilamentView::registerRenderHook(
            PanelsRenderHook::BODY_START,
            fn (): string => Blade::render('@livewire(\'announcement\')'),
        );
    }
}

// Annoucement components
use Livewire\Component;

class Announcement extends Component
{
    public $message = 'Test';

    public function render()
    {
        return view('livewire.announcement');
    }
}

// blade
<div>
    {{ $message }}
</div>

// AppServiceProviders
use Filament\Support\Facades\FilamentView;
use Filament\View\PanelsRenderHook;
use Illuminate\Support\Facades\Blade;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        FilamentView::registerRenderHook(
            PanelsRenderHook::BODY_START,
            fn (): string => Blade::render('@livewire(\'announcement\')'),
        );
    }
}

// Annoucement components
use Livewire\Component;

class Announcement extends Component
{
    public $message = 'Test';

    public function render()
    {
        return view('livewire.announcement');
    }
}

// blade
<div>
    {{ $message }}
</div>

This is my code in AppServiceProvider

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Filament\Support\Facades\FilamentView;
use Illuminate\Contracts\View\View;
use Filament\View\PanelsRenderHook;
use Illuminate\Support\Facades\Blade;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {

    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        FilamentView::registerRenderHook(
            PanelsRenderHook::GLOBAL_SEARCH_BEFORE,
            fn (): View => view('livewire.clock'),
        );

        FilamentView::registerRenderHook(
            PanelsRenderHook::BODY_START,
            fn (): string => Blade::render('@livewire(\'announcement\')'),
        );
    }
}
