Laravel Blade is one of the most powerful and advanced templating engine as compared to other templating engines such as Smarty and Twig.

- Control Structures

@if, @elseif, @else, @endif

Conditional logic.

@if ($user->isAdmin())
    Welcome, admin!
@elseif ($user->isModerator())
    Welcome, moderator!
@else
    Welcome, guest!
@endif

@unless / @endunless

Reverse of @if.

@unless ($user->isBanned())
    You can access the forum.
@endunless

@isset / @endisset

Checks if a variable is set.

@isset ($profile)
    {{ $profile->bio }}
@endisset

@empty / @endempty

Checks if a variable is empty.

@empty ($notifications)
    You have no notifications.
@endempty

- Loops

@for / @endfor

Classic for-loop.

@for ($i = 0; $i < 5; $i++)
    Number: {{ $i }}
@endfor

@foreach / @endforeach

For collections or arrays.

@foreach ($users as $user)
    {{ $user->name }}
@endforeach

@forelse / @empty / @endforelse

foreach with a fallback if empty.

@forelse ($comments as $comment)
    {{ $comment->body }}
@empty
    No comments found.
@endforelse

@while / @endwhile

Basic while loop.

@while ($count < 3)
    Count: {{ $count++ }}
@endwhile

- Authentication & Authorization

@auth / @endauth

Content for authenticated users.

@auth
    Welcome back, {{ auth()->user()->name }}!
@endauth

@guest / @endguest

Content for unauthenticated users.

@guest
    <a href="/login">Login</a>
@endguest

@can / @endcan / @cannot / @endcannot

Laravel policies or gates.

@can('update', $post)
    <a href="#">Edit Post</a>
@endcan
@cannot('delete', $comment)
    You cannot delete this comment.
@endcannot

@canany / @endcanany

If the user has any of the listed abilities.

@canany(['update', 'delete'], $post)
    <p>You can edit or delete this post.</p>
@endcanany

- Environment & Section Management

@env / @endenv

Conditionally render for environments.

@env('local')
    <p>App is running in local</p>
@endenv

@env(['staging', 'production'])
    <p>Staging or Production</p>
@endenv

@production / @endproduction

Production environment.

@production
    <p>Production environment</p>
@endproduction

@section / @endsection

Define content sections for layouts.

@section('content')
    <p>This is the page content</p>
@endsection

@yield

Used in layouts to show section content.

<body>
    @yield('content')
</body>

@extends

Extend a layout.

@extends('layouts.app')

@include

Include another view.

@include('partials.header')

@include('partials.sidebar', ['menu' => $menu])

@includeIf / @includeWhen / @includeUnless

Conditional includes.

@includeIf('partials.footer')

@includeWhen($showSidebar, 'partials.sidebar')

@includeUnless($isGuest, 'partials.user-info')

@each

Loop through and render a partial.

@each('partials.comment', $comments, 'comment')

@stack / @push

The stack directive allows you to render content somewhere else in another view or layout. By using the push directive you can add content to a stack. This is often used to render JavaScript and CSS includes.

For example, on the blog detail view we could push a JavaScript file that needs to be included. We can do this by pushing the HTML to the scripts stack.

@push('scripts')
    <script src="/blog-detail.js"></script>
@endpush

In the <head> tag of the layout we could render the complete stack contents by using the stack directive and passing the name of the stack, scripts in this case.

<head>
    <!-- Your head content -->

    @stack('scripts')
</head>

- Components & Slots

@component / @slot / @endcomponent

For inline component-like templates.

@component('components.alert')
    @slot('title')
        Error
    @endslot

    Something went wrong!
@endcomponent

@props

Used in Blade component files to define props.

@props(['type' => 'info'])

<div class="alert alert-{{ $type }}">
    {{ $slot }}
</div>

- Verbatim & Raw Output

@verbatim / @endverbatim

Prevent Blade from parsing.

@verbatim
    <script>
        let data = {{ $rawJson }};
    </script>
@endverbatim

{!! !!}

Unescaped output.

{!! $html !!}

- PHP and Debugging

@php / @endphp

Write raw PHP.

@php
    $status = 'active';
@endphp

@dd / @dump

Debug inside Blade.

@dd($user)

@dump($posts)

- Switch Statement

@switch / @case / @break / @default / @endswitch

@switch($role)
    @case('admin')
        Admin Panel
        @break

    @case('editor')
        Editor Panel
        @break

    @default
        User Dashboard
@endswitch

- Comments

Blade comment (not shown in HTML).

{{-- This is a Blade comment --}}

- Other Useful Directives

@csrf

Generates CSRF token input.

<form method="POST">
    @csrf
</form>

@method

Spoof HTTP method for forms (e.g., PUT, DELETE).

<form method="POST">
    @method('PUT')
</form>

@error / @enderror

Show validation errors.

@error('email')
    <div>{{ $message }}</div>
@enderror

@json

<script>
    var users = {!! json_encode($users) !!};
</script>

// translates to

<script>
    var users = @json($users);
</script>
