Laravel 路由未定义错误

2022-01-02 00:00:00 url routes php laravel laravel-5

我不断收到未定义路由的错误，如果我使用 url() 我得到服务器无法提供安全连接错误.我希望我能得到一些帮助.

I keep getting route not defined error and if I use url() I get server can not provide a secure connection error. I hope I can get some help.

路线

Route::get('/show/{table_name}/{product_id}', 'PageCotroller@showdetails')->name('product-show');

查看:

<h4><a href="{{ url('product-show' .$table_name . '/' .$product->item_id)}}">{{ $product->title }}</a></h4>

控制器:

   public function showdetails($table_name,$pid){

       $categories = Category::all();
       $data['product_id']=$pid;
       $data['table']=$table_name;
       $shop_name=Shop::all();
       $query = DB::table($table_name)
       ->select('*')
       ->where('item_id', '=', $pid)
       ->get();;
       $image=Item_image::all();
           $pro_img = DB::table('item_images')
               ->select('image_loc')
               ->where('prod_id', $pid)
               ->get();
   return view('show_details',compact('categories','image','pro_img','table_name','shop_name'));

}

推荐答案

要按名称调用路由，您应该使用 route 函数并将参数添加到数组中作为第二个参数.

To call a route by name, you should use the route function and add the parameters in an array as the second parameter.

route('product-show', [$table_name, $product->item_id])

您收到路由未定义错误的原因是您正在生成 url /product-show/{table_name}/{product_id} 而实际 url 是 /show/{table_name}/{product_id}.此外，当有许多辅助函数为您执行此操作时，手动添加参数是不好的做法.

The reason you get a route not defined error is that you are generating the url /product-show/{table_name}/{product_id} and the actual url is /show/{table_name}/{product_id}. Also, adding the parameters manually is bad practice when there are many helper functions that do this for you.
