如何 foreach 嵌套在 Laravel Blade 中的动态 JSON

Question

I want to loop through (foreach) this data dynamically when there is new data, how can I do this? I use the package laravel-nestedable .

This is my return JSON, which is dynamic:

[
   {
      "id":1,
      "name":"food",
      "slug":"food",
      "child":[
         {
            "id":2,
            "name":"cake",
            "slug":"cake",
            "child":[
               {
                  "id":3,
                  "name":"Rainbow Cake",
                  "slug":"rainbow-cake",
                  "child":[

                  ],
                  "parent_id":2
               },
               {
                  "id":4,
                  "name":"Banana Cake",
                  "slug":"banana-cake",
                  "child":[

                  ],
                  "parent_id":2
               }
            ],
            "parent_id":1
         },
         {
            "id":5,

Your Json data not seems to be correctly formatted but if its fine then you can send your Json data from Controller to View like below:

return view('your-view')->with('json', $json);

or

return view('your-view', ['json'=>$json]);

or

return View::make('your-view')->with('json', $json);

Then in your blade file you need to use foreach to get all data like below:

@foreach($json as $data)
    {{ $data->item }}
@endforeach

You can also convert your Json data to array and then send like below:

$array =json_decode( json_encode($json), true);
return view('your-view')->with('array', $array);

Then in your blade file you need to use foreach to get all data like below:

@foreach($array as $data)
    {{ $data['item'] }}
@endforeach
