Question

我将视图传递给广告系列。如果我做

{{ dd($campaign->campaignCreatives->campaignCreativesData) }}

我得到像

这样的东西

Collection {#348 ▼
  #items: array:2 [▼
    0 => CampaignCreativesData {#349 ▼
      #attributes: array:7 [▼
        "id" => "5"
        "name" => "creativeOption"
        "label" => "Other"
        "value" => "sdfsdfsdfsdfsdf"
        "campaignCreativesId" => "5"
        "created_at" => "2016-03-01 10:24:38"
        "updated_at" => "2016-03-01 10:24:38"
      ]

    }
    1 => CampaignCreativesData {#350 ▼
      #attributes: array:7 [▼
        "id" => "4"
        "name" => "creativeOption"
        "label" => "checkboxSelection"
        "value" => "Animated GIF"
        "campaignCreativesId" => "5"
        "created_at" => "2016-03-01 10:24:38"
        "updated_at" => "2016-03-01 10:24:38"
      ]
    }
  ]
}

如果我把它投射到数组

{{ dd($campaign->campaignCreatives->campaignCreativesData->toArray()) }}

我得到像

这样的东西

array:2 [▼
  0 => array:7 [▼
    "id" => "5"
    "name" => "creativeOption"
    "label" => "Other"
    "value" => "sdfsdfsdfsdfsdf"
    "campaignCreativesId" => "5"
    "created_at" => "2016-03-01 10:24:38"
    "updated_at" => "2016-03-01 10:24:38"
  ]
  1 => array:7 [▼
    "id" => "4"
    "name" => "creativeOption"
    "label" => "checkboxSelection"
    "value" => "Animated GIF"
    "campaignCreativesId" => "5"
    "created_at" => "2016-03-01 10:24:38"
    "updated_at" => "2016-03-01 10:24:38"
  ]
]

现在我有几个复选框，如果值在数组中，我需要选中复选框。目前我有类似的东西

{!! Form::checkbox('creativeOptions[]', 'Animated GIF', in_array('Animated GIF', $campaign->campaignCreatives->campaignCreativesData->toArray()), ['class' => 'styled', 'id' => 'checkbox1']) !!}

如您所见，动画GIF位于数组中，但未选中复选框。

如何根据数组中的内容选中复选框？

您可以在Laravel集合中使用方法contains。

{!! Form::checkbox('creativeOptions[]', 
    'Animated GIF', 
    $campaign->campaignCreatives->campaignCreativesData->contains('value', 'Animated GIF'), 
    ['class' => 'styled', 'id' => 'checkbox1']) !!}
