Undefined variable: header (View: /var/www/html/Laravel/Laravel8/resources/views/layouts/app.blade.php)

Hey @sr57

Try putting the following at the top of your blade file:-

<x-app-layout>
    <x-slot name="header">
        <h2>Page Titel</h2>
    </x-slot>
</x-app-layout>

// The rest of your code...

No change :-(

Can you show us your tasks/index.blade.php file?

@extends('layouts.app')

@section('content')

All Tasks

@foreach($tasks as $task) {{$task->title}}

                <div class="card-body">
                    {{$task->description}}
                </div>
            </div>
            @endforeach
        </div>
    </div>
</div>

@endsection

I have a pb to paste the code in the post, how can I put it in "raw mode"?

Try like this:

<x-app-layout>
    <x-slot name="header">
        <h2 class="font-semibold text-xl text-gray-800 leading-tight">
            {{ __('All Tasks') }}
        </h2>
    </x-slot>

// your content

</x-app-layout>

No change :-(

It's my first test with Laravel and I took Laravel 5 example with a Laravel 8 project. Ok (till now) with the goof example.

Hi @sr57

Are you using livewire or traditional blade?

livewire

@sr57 Ah cool, in which case... presuming you have the following in app.blade

<header class="bg-white shadow md:border-b border-gray-100">
    <div class="mx-auto py-6 px-4 sm:px-6 lg:px-8">
        {{ $header }}
    </div>
</header>

use this in your component....

<x-slot name="header">
        <h2 class="font-semibold text-xl text-gray-800 leading-tight">
            {{ __('Your Page Title') }}
        </h2>
</x-slot>
