laravel 的视图合成器可将数据与指定视图绑定在一起，避免了重复编写代码。
View::composer('profile', 'AppHttpViewComposersProfileComposer');
由于数据的生成和渲染是分开进行的，理解起来不够直观。因此，可以采用视图组件的方式将两者进行封装。
<?php namespace AppViewComponents; use IlluminateContractsSupportHtmlable; use IlluminateHttpRequest; use IlluminateSupportFacadesView; class ExampleComponent implements Htmlable { private $color; private $request; public function __construct(Request $request, string $color) { $this->color = $color; $this->request = $request; } public function toHtml() { return View::make('example') ->with('color', $this->color) ->render(); } }
在视图中使用
{{ app()->makeWith(AppViewComponentsExampleComponent::class,['color' => 'green'])->toHtml() }}
封装指令
Blade::directive('render', function ($expression) { list($class, $params) = explode(',', $expression, 2); $class = "AppViewComponents".trim($class, ''" '); return "<?php echo app()->makeWith('$class', $params)->toHtml(); ?>"; });
使用指令
@render('ExampleComponent', ['color' => 'green'])
