# Kiri Blade 模板引擎
|
||||
|
||||
这是一个类似 Laravel Blade 的模板引擎实现，用于 kiri-router 项目。
|
||||
|
||||
## 功能特性
|
||||
|
||||
- ✅ 变量输出：`{{ $variable }}` 和 `{!! $variable !!}`
|
||||
- ✅ 控制结构：`@if`, `@elseif`, `@else`, `@endif`
|
||||
- ✅ 循环：`@foreach`, `@endforeach`, `@for`, `@endfor`, `@while`, `@endwhile`
|
||||
- ✅ 布局继承：`@extends`, `@section`, `@yield`, `@endsection`
|
||||
- ✅ 包含视图：`@include`
|
||||
- ✅ 注释：`{{-- comment --}}`
|
||||
- ✅ 原始 PHP：`@php ... @endphp`
|
||||
- ✅ 编译缓存：自动缓存编译后的模板以提高性能
|
||||
|
||||
## 使用方法
|
||||
|
||||
### 基本用法
|
||||
|
||||
```php
|
||||
use function Kiri\Router\View;
|
||||
|
||||
// 在控制器中渲染视图
|
||||
return View('user.profile', [
|
||||
'name' => 'John Doe',
|
||||
'email' => 'john@example.com'
|
||||
]);
|
||||
```
|
||||
|
||||
### 视图文件结构
|
||||
|
||||
视图文件应放在 `resources/view` 目录下，使用 `.blade.php` 扩展名：
|
||||
|
||||
```
|
||||
resources/
|
||||
view/
|
||||
layouts/
|
||||
app.blade.php
|
||||
user/
|
||||
profile.blade.php
|
||||
components/
|
||||
header.blade.php
|
||||
```
|
||||
|
||||
### 模板语法示例
|
||||
|
||||
#### 1. 变量输出
|
||||
|
||||
```blade
|
||||
<!-- 转义输出 -->
|
||||
<h1>{{ $title }}</h1>
|
||||
<p>{{ $description }}</p>
|
||||
|
||||
<!-- 原始输出（不转义） -->
|
||||
<div>{!! $htmlContent !!}</div>
|
||||
```
|
||||
|
||||
#### 2. 条件语句
|
||||
|
||||
```blade
|
||||
@if($user->isAdmin())
|
||||
<p>管理员</p>
|
||||
@elseif($user->isModerator())
|
||||
<p>版主</p>
|
||||
@else
|
||||
<p>普通用户</p>
|
||||
@endif
|
||||
```
|
||||
|
||||
#### 3. 循环
|
||||
|
||||
```blade
|
||||
@foreach($users as $user)
|
||||
<div>
|
||||
<h3>{{ $user->name }}</h3>
|
||||
<p>{{ $user->email }}</p>
|
||||
</div>
|
||||
@endforeach
|
||||
|
||||
@for($i = 0; $i < 10; $i++)
|
||||
<p>Item {{ $i }}</p>
|
||||
@endfor
|
||||
```
|
||||
|
||||
#### 4. 布局继承
|
||||
|
||||
**layouts/app.blade.php:**
|
||||
```blade
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<head>
|
||||
<title>@yield('title', '默认标题')</title>
|
||||
</head>
|
||||
<body>
|
||||
<header>
|
||||
@include('components.header')
|
||||
</header>
|
||||
|
||||
<main>
|
||||
@yield('content')
|
||||
</main>
|
||||
|
||||
<footer>
|
||||
<p>© 2024</p>
|
||||
</footer>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
**user/profile.blade.php:**
|
||||
```blade
|
||||
@extends('layouts.app')
|
||||
|
||||
@section('title')
|
||||
用户资料
|
||||
@endsection
|
||||
|
||||
@section('content')
|
||||
<h1>用户资料</h1>
|
||||
<p>姓名：{{ $name }}</p>
|
||||
<p>邮箱：{{ $email }}</p>
|
||||
@endsection
|
||||
```
|
||||
|
||||
#### 5. 包含视图
|
||||
|
||||
```blade
|
||||
@include('components.header')
|
||||
|
||||
@include('components.footer', ['year' => 2024])
|
||||
```
|
||||
|
||||
#### 6. 注释
|
||||
|
||||
```blade
|
||||
{{-- 这是注释，不会输出到 HTML --}}
|
||||
```
|
||||
|
||||
#### 7. 原始 PHP
|
||||
|
||||
```blade
|
||||
@php
|
||||
$count = count($items);
|
||||
$total = array_sum($prices);
|
||||
@endphp
|
||||
|
||||
<p>总数：{{ $count }}</p>
|
||||
```
|
||||
|
||||
## 高级用法
|
||||
|
||||
### 自定义指令
|
||||
|
||||
```php
|
||||
use Kiri\Router\Blade\BladeHelper;
|
||||
|
||||
$factory = BladeHelper::getFactory();
|
||||
|
||||
// 注册自定义指令
|
||||
$factory->directive('datetime', function ($expression) {
|
||||
return "<?php echo date('Y-m-d H:i:s', {$expression}); ?>";
|
||||
});
|
||||
```
|
||||
|
||||
使用自定义指令：
|
||||
|
||||
```blade
|
||||
@datetime(time())
|
||||
```
|
||||
|
||||
### 共享数据
|
||||
|
||||
```php
|
||||
use Kiri\Router\Blade\BladeHelper;
|
||||
|
||||
$factory = BladeHelper::getFactory();
|
||||
|
||||
// 共享数据到所有视图
|
||||
$factory->share('siteName', 'My Website');
|
||||
$factory->share([
|
||||
'version' => '1.0.0',
|
||||
'author' => 'Kiri Team'
|
||||
]);
|
||||
```
|
||||
|
||||
### 清除缓存
|
||||
|
||||
```php
|
||||
use Kiri\Router\Blade\BladeHelper;
|
||||
|
||||
$factory = BladeHelper::getFactory();
|
||||
$factory->clearCache();
|
||||
```
|
||||
|
||||
## 配置
|
||||
|
||||
视图路径和缓存路径可以通过常量配置：
|
||||
|
||||
```php
|
||||
// 视图路径
|
||||
define('APP_PATH', __DIR__ . '/');
|
||||
|
||||
// 缓存路径（可选）
|
||||
define('RUNTIME_PATH', __DIR__ . '/runtime');
|
||||
```
|
||||
|
||||
默认情况下：
|
||||
- 视图路径：`APP_PATH . 'resources/view'`
|
||||
- 缓存路径：`RUNTIME_PATH . '/blade'` 或系统临时目录
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. 模板文件必须使用 `.blade.php` 扩展名
|
||||
2. 视图路径使用点号分隔，如 `user.profile` 对应 `user/profile.blade.php`
|
||||
3. 编译后的模板会自动缓存，修改源文件后会自动重新编译
|
||||
4. 建议在生产环境中定期清理缓存目录
