View::composer('profile', 'App\Http\View\Composers\ProfileComposer');
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 App\ViewComponents; use Illuminate\Contracts\Support\Htmlable; use Illuminate\Http\Request; use Illuminate\Support\Facades\View; 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', $this->color) ->render(); } }
在视图中使用
{{ app()->makeWith(App\ViewComponents\ExampleComponent::class,['color' => 'green'])->toHtml() }}
封装指令
Blade::directive('render', function ($expression) { list($class, $params) = explode(',', $expression, 2); $class = App\\ViewComponents\\.trim($class, '\' '); return <?PHP echo app()->makeWith('$class', $params)->toHtml(); ?>; });
使用指令
@render('ExampleComponent', ['color' => 'green'])
