Question

我正在创建一个Laravel 4 webapp并获得以下路线：

Route::get('products/{whateverId}', 'ProductController@index');

这是我在ProductController中的索引函数：

    public function index($whateverId)
{
    $products = Product::all();
    $data['whateverId'] = $whateverId;
    return View::make('products', compact('products'), $data);
}

在我看来，这会返回以下错误：

<p>Product: {{ $data['product'] }}</p>

ErrorException 未定义的变量：data（查看：/Users/myuser/webapp/app/views/products.blade.php）

Answer 1

return View::make('products', compact('products'), "data"=>$data);

（或compact('data')）

Answer 2

尝试将其传递为：

$data['whateverId'] = $whateverId;

$data['products'] = Product::all();;

return View::make('products', $data);

你可以访问

{{ foreach($products as ...) }}

和

{{ $whateverId }}

或者你可以

$products = Product::all();

$data['whateverId'] = $whateverId;

return View::make('products')
         ->with('products', $products)
         ->with('whateverId', $whateverId);

通过控制器从路径到视图传递参数不起作用
