Question

我想使用createMany创建多条记录，如何在没有数据复制的情况下将数组插入此方法？

 public function update(Request $request, Question $question)
    {
        $options = $request->only('title', 'description', 'question_id');

        $options_data = [];

        foreach ($options as $key => $value) {

            $options_data[] =[
                'title' => $options[$key],
                'description' =>$options[$key],
                'question_id' => $options[$key]
            ];

        }

        $question->options()->createMany($options_data);

结果：dd（）我提交2条记录和3个字段

array:3 [▼
  0 => array:3 [▼
    "title" => array:2 [▼
      0 => "option one"
      1 => "option two"
    ]
    "description" => array:2 [▼
      0 => "option one"
      1 => "option two"
    ]
    "question_id" => array:2 [▼
      0 => "option one"
      1 => "option two"
    ]
  ]
  1 => array:3 [▼
    "title" => array:2 [▼
      0 => "option description"
      1 => "option two description"
    ]
    "description" => array:2 [▼
      0 => "option description"
      1 => "option two description"
    ]
    "question_id" => array:2 [▼
      0 => "option description"
      1 => "option two description"
    ]
  ]
  2 => array:3 [▼
    "title" => array:2 [▼
      0 => "14"
      1 => "14"
    ]
    "description" => array:2 [▼
      0 => "14"
      1 => "14"
    ]
    "question_id" => array:2 [▼
      0 => "14"
      1 => "14"
    ]
  ]
]

我的表单有3个字段，可提交给此模型标题[]，说明[]，question_id [] 这种形式是可重复的形式

据我所知，您没有正确形成html文件。您的html文件应如下所示：

<input type="text" name="items[1][title]">
<input type="text" name="items[1][description]">
<input type="text" name="items[1][question_id]">

<input type="text" name="items[2][title]">
<input type="text" name="items[2][description]">
<input type="text" name="items[2][question_id]">

$options = $request->only('items');

$options_data = [];

foreach ($options as $key => $value) {
     $options_data[] = $value;
}

$question->options()->createMany($options_data);
