Blade Templates

Overview

Lyger includes a lightweight Blade-inspired templating engine for rendering dynamic views. The Blade engine provides a clean syntax for working with PHP templates, layouts, and components.

Lyger’s Blade implementation (Lyger\Livewire\Blade) is a simplified version designed for performance and ease of use.

Basic Usage

Setting Up Blade

Configure the views and cache paths:

use Lyger\Livewire\Blade;

// Set the views directory
Blade::setViewsPath(__DIR__ . '/resources/views');

// Set the cache directory
Blade::setCachePath(__DIR__ . '/storage/cache/views');

Rendering Views

Basic Rendering
Dot Notation
View Facade

use Lyger\Livewire\Blade;

// Render a view with data
$html = Blade::render('welcome', [
    'title' => 'Welcome to Lyger',
    'user' => 'John Doe',
]);

echo $html;

// Use dot notation for nested directories
// Renders: resources/views/admin/dashboard.php
$html = Blade::render('admin.dashboard', [
    'stats' => $statistics,
]);

use Lyger\Livewire\View;

// Alternative syntax using View facade
$html = View::make('profile.show', [
    'user' => $currentUser,
]);

Template Files

Create template files in your views directory:

<!-- resources/views/welcome.php -->
<!DOCTYPE html>
<html>
<head>
    <title><?= $title ?></title>
</head>
<body>
    <h1>Hello, <?= $user ?>!</h1>
    <p>Welcome to the application.</p>
</body>
</html>

Variable Extraction

All data passed to the view is automatically extracted as variables:

Blade::render('profile', [
    'name' => 'John Doe',
    'email' => 'john@example.com',
    'age' => 30,
]);

<!-- resources/views/profile.php -->
<div class="profile">
    <h2><?= $name ?></h2>
    <p>Email: <?= $email ?></p>
    <p>Age: <?= $age ?></p>
</div>

Includes and Partials

Including Partials

Use Blade::include() to include partial views:

<!-- resources/views/dashboard.php -->
<div class="dashboard">
    <h1>Dashboard</h1>
    
    <?= Blade::include('partials.sidebar', ['items' => $menuItems]) ?>
    
    <div class="content">
        <?= $mainContent ?>
    </div>
</div>

<!-- resources/views/partials/sidebar.php -->
<aside class="sidebar">
    <ul>
        <?php foreach ($items as $item): ?>
            <li><a href="<?= $item['url'] ?>"><?= $item['label'] ?></a></li>
        <?php endforeach; ?>
    </ul>
</aside>

Layouts and Sections

Defining Layouts

Create a layout template with yield points:

<!-- resources/views/layouts/app.php -->
<!DOCTYPE html>
<html>
<head>
    <title><?= Blade::yield('title') ?> - My App</title>
    <link rel="stylesheet" href="/css/app.css">
</head>
<body>
    <header>
        <?= Blade::yield('header') ?>
    </header>
    
    <main>
        <?= Blade::yield('content') ?>
    </main>
    
    <footer>
        <?= Blade::yield('footer') ?>
    </footer>
</body>
</html>

Extending Layouts

Extend Layout

Use Blade::extends() to specify the parent layout:

<!-- resources/views/pages/home.php -->
<?php Blade::extends('layouts.app'); ?>

Define Sections

Use Blade::start() and Blade::end() to define section content:

<?php Blade::start('title'); ?>
Home Page
<?php Blade::end(); ?>

<?php Blade::start('header'); ?>
<nav>
    <a href="/">Home</a>
    <a href="/about">About</a>
</nav>
<?php Blade::end(); ?>

<?php Blade::start('content'); ?>
<h1>Welcome to Our Site</h1>
<p>This is the home page content.</p>
<?php Blade::end(); ?>

Complete Layout Example

<!-- resources/views/layouts/master.php -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title><?= Blade::yield('title') ?></title>
    <?= Blade::yield('styles') ?>
</head>
<body>
    <div class="container">
        <?= Blade::yield('content') ?>
    </div>
    <?= Blade::yield('scripts') ?>
</body>
</html>

Components

Rendering Components

Use Blade::component() to render Livewire or component class instances:

<?php
use Lyger\Livewire\Blade;

// Render a component with props
$html = Blade::component(App\Livewire\Counter::class, [
    'initialCount' => 10,
    'step' => 2,
]);

echo $html;
?>

Component in Views

<!-- resources/views/dashboard.php -->
<div class="dashboard">
    <h1>Dashboard</h1>
    
    <?= Blade::component(App\Components\StatsCard::class, [
        'title' => 'Total Users',
        'value' => $userCount,
        'icon' => 'users',
    ]) ?>
    
    <?= Blade::component(App\Components\StatsCard::class, [
        'title' => 'Revenue',
        'value' => '$' . number_format($revenue, 2),
        'icon' => 'dollar',
    ]) ?>
</div>

Loop Helper

The Blade::each() method simplifies rendering lists:

use Lyger\Livewire\Blade;

$users = [
    ['name' => 'John', 'email' => 'john@example.com'],
    ['name' => 'Jane', 'email' => 'jane@example.com'],
    ['name' => 'Bob', 'email' => 'bob@example.com'],
];

$html = Blade::each($users, 'partials.user-item', 'user');
echo $html;

<!-- resources/views/partials/user-item.php -->
<div class="user-item">
    <h3><?= $user['name'] ?></h3>
    <p><?= $user['email'] ?></p>
    <p>Item <?= $loop['iteration'] ?> of <?= $loop['count'] ?></p>
    
    <?php if ($loop['first']): ?>
        <span class="badge">First</span>
    <?php endif; ?>
    
    <?php if ($loop['last']): ?>
        <span class="badge">Last</span>
    <?php endif; ?>
</div>

Loop Variables

The $loop variable provides useful iteration data:

Variable	Description
`$loop['index']`	Zero-based index (0, 1, 2…)
`$loop['iteration']`	Current iteration (1, 2, 3…)
`$loop['first']`	True if first iteration
`$loop['last']`	True if last iteration
`$loop['count']`	Total number of items

Blade Directives

The Lyger\Livewire\Directives class provides common template directives:

Conditional Directives

@if
@isset
@empty

use Lyger\Livewire\Directives;

$html = Directives::if('$isAdmin', '<button>Delete</button>');
// Output: <?php if($isAdmin): ?> <button>Delete</button> <?php endif; ?>

$html = Directives::isset('$user', '<p>Welcome, <?= $user->name ?></p>');
// Output: <?php if(isset($user)): ?> <p>Welcome...</p> <?php endif; ?>

$html = Directives::empty('$items', '<p>No items found</p>');
// Output: <?php if(empty($items)): ?> <p>No items found</p> <?php endif; ?>

Loop Directives

use Lyger\Livewire\Directives;

$html = Directives::foreach(
    '$users',
    '$user',
    '<li><?= $user->name ?></li>'
);

// Output:
// <?php foreach($users as $user): ?>
//     <li><?= $user->name ?></li>
// <?php endforeach; ?>

Authentication Directives

use Lyger\Livewire\Directives;

// @auth directive
$html = Directives::auth(
    '<a href="/dashboard">Dashboard</a>',
    '<a href="/login">Login</a>'
);

// Output:
// <?php if(auth()->check()): ?>
//     <a href="/dashboard">Dashboard</a>
// <?php else: ?>
//     <a href="/login">Login</a>
// <?php endif; ?>

// @can directive
$html = Directives::can('edit-posts', '<button>Edit</button>');

// Output:
// <?php if(auth()->can('edit-posts')): ?>
//     <button>Edit</button>
// <?php endif; ?>

Switch Directive

use Lyger\Livewire\Directives;

$html = Directives::switch('$status', [
    'pending' => '<span class="badge-yellow">Pending</span>',
    'approved' => '<span class="badge-green">Approved</span>',
    'rejected' => '<span class="badge-red">Rejected</span>',
], '<span class="badge-gray">Unknown</span>');

// Output:
// <?php switch($status): ?>
//     <?php case 'pending': ?>
//         <span class="badge-yellow">Pending</span>
//         <?php break; ?>
//     <?php case 'approved': ?>
//         <span class="badge-green">Approved</span>
//         <?php break; ?>
//     <?php case 'rejected': ?>
//         <span class="badge-red">Rejected</span>
//         <?php break; ?>
//     <?php default: ?>
//         <span class="badge-gray">Unknown</span>
// <?php endswitch; ?>

Shared Data

Share data across all views:

use Lyger\Livewire\View;

// Share data globally
View::share('siteName', 'My Application');
View::share('currentYear', date('Y'));

// Access in any view
$siteName = View::getShared('siteName');

<!-- Any view file -->
<footer>
    <p>&copy; <?= View::getShared('currentYear') ?> <?= View::getShared('siteName') ?></p>
</footer>

Error Handling

Blade automatically handles template errors:

use Lyger\Livewire\Blade;

$html = Blade::render('non-existent-view', []);

// Output: "View not found: non-existent-view"

// Catch rendering errors
try {
    $html = Blade::render('problematic-view', ['data' => $data]);
} catch (\Throwable $e) {
    // Output: "Error rendering view: [error message]"
    error_log($e->getMessage());
}

Integration with Livewire

Use Blade to render Livewire component views:

namespace App\Livewire;

use Lyger\Livewire\Component;
use Lyger\Livewire\Blade;

class UserProfile extends Component
{
    public string $name = '';
    public string $email = '';

    public function render(): string
    {
        return Blade::render('livewire.user-profile', [
            'name' => $this->name,
            'email' => $this->email,
        ]);
    }
}

<!-- resources/views/livewire/user-profile.php -->
<div class="user-profile">
    <h2><?= $name ?></h2>
    <p><?= $email ?></p>
    
    <button wire:click="updateProfile">Update</button>
</div>

Best Practices

Organize Views

Use a consistent directory structure:

resources/views/
├── layouts/
│   ├── app.php
│   └── admin.php
├── partials/
│   ├── header.php
│   └── footer.php
├── components/
│   └── card.php
└── pages/
    ├── home.php
    └── about.php

Escape Output

Always escape user-generated content to prevent XSS:

<p><?= htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8') ?></p>

Keep Logic Minimal

Avoid complex business logic in templates. Use controllers or components for data processing.

Reuse Partials

Extract repeated markup into partials for better maintainability.

Use Dot Notation

Organize views in subdirectories and use dot notation for cleaner code:

Blade::render('admin.users.index', $data);
// Instead of: Blade::render('admin/users/index', $data);

Practical Examples

Complete Page Example

<?php

namespace App\Controllers;

use Lyger\Livewire\Blade;

class BlogController
{
    public function show(int $id)
    {
        $post = Post::find($id);
        $comments = Comment::where('post_id', $id)->get();
        $related = Post::where('category', $post->category)
            ->limit(3)
            ->get();

        return Blade::render('blog.show', [
            'post' => $post,
            'comments' => $comments,
            'related' => $related,
        ]);
    }
}
