laravel如何從輸入

Question

我有一個設置爲JSON值的輸入項目，因爲我想以後得到控制這個價值得到JSON的價值，但我只是得到[對象，對象]

的JSON是：

[{ 
    "title": "G30 BMW 530d is Victoria Police's new patrol car - 80 units to join fleet by end-2018, all with 'police pack'", 
    "url": "https://paultan.org/2017/09/20/g30-bmw-530d-is-victoria-police-new-patrol-car/", 
    "thumbnail": "https://s1.paultan.org/image/2017/09/VP_HWP_Bmw_530D_Front_side.jpg", 
    "source": "Paul Tan's Automotive News", 
    "source_url": "https://paultan.org/2017/09/20/g30-bmw-530d-is-victoria-police-new-patrol-car/", 
    "date_published": "2017-09-20", 
    "provider": "Event Registry", 
    "provider_url": "http://eventregistry.org" 
}, { 
    "title": "Opel Astra GSi Spied Nearly Naked", 
    "url": "http://gmauthority.com/blog/2017/09/opel-astra-gsi-spied-nearly-naked/", 
    "thumbnail": "http://gmauthority.com/blog/wp-content/uploads/2017/07/Opel-GSi-Teaser-1024x771.jpg", 
    "source": "GM Authority", 
    "source_url": "http://gmauthority.com/blog/2017/09/opel-astra-gsi-spied-nearly-naked/", 
    "date_published": "2017-09-19", 
    "provider": "Event Registry", 
    "provider_url": "http://eventregistry.org" 
}] 

Vuejs

<div v-for="article in articles_sortByDate" v-bind:key="article.id"> 
    <input type="checkbox" 
      :value="article" 
      v-model="checkedArtcles" 
      name='checkedArtcles'> 
</div> 

現在，如果我嘗試從控制器該值與

dd($request->input('checkedArtcles')); 

//this results in [Object, object] 

也試過：

dd(json_decode($request->input('checkedArtcles'))); 

//this return NUll 

Answer 1

在JavaScript邏輯（在這種情況下VUE）解析您的JSON字符串，然後追加選擇的值，然後在C ontroller，你可以嘗試訪問$request->input('checkedArtcles')或dd。

Answer 2

如果你不希望對象，解碼字符串，但添加true給你一個關聯數組：

$array = json_decode($string, true);
