Question

我尝试在每次job_id时插入多个数组，当我尝试这个我的数组值输出为空值这是我的存储函数

$input输出：

array:7 [▼ 
     "date" => "2016-01-10",
     "job_id" => "2",
     "charge" => array:2 [▼ 
           0 => "ch1",
           1 => "ch2" 
     ],
     "category" => array:2 [▼
          0 => "se1",
          1 => "se2" 
     ],
     "amount" => array:2 [▼
          0 => "100"
          1 => "200" 
     ]
 ]

完整代码：

$input = Input::all();

$charge = Input::get('charge');
$date = Input::get('date');
$job = Input::get('job_id');
$amount = Input::get('amount');
$cat = Input::get('category');
$id = \Auth::id();

$data = array();

foreach ($charge as $key=>$value ){
    $data[] = [
          'date' => $date,
          'charge'=>$key['charge'],
          'job_id'=>$job,
          'user_id'=>$id,
          'amount'=>$key['amount'],
          'category'=>$key['category'],
    ];
}

dd($data);

当我试图退出时，我会得到这个

array:2 [▼
  0 => array:6 [▼
    "date" => "2016-01-10"
    "charge" => null
    "job_id" => "2"
    "user_id" => 1
    "amount" => null
    "category" => null
  ]
  1 => array:6 [▼
    "date" => "2016-01-10"
    "charge" => null
    "job_id" => "2"
    "user_id" => 1
    "amount" => null
    "category" => null
  ]
]

我想要的是我想在我的数据库中插入数据任何人都建议我好主意？

您的最终输出看起来是正确的，请尝试使用以下代码将$data插入您的数据库：

Model::insert($data); // Eloquent
DB::table('table')->insert($data); // Query Builder

您应该使用$inputs['amount'][$key]为数值构建数组，并使用$inputs['category'][$key]为类别构建数组，如下所示：

foreach ($charge as $key=>$value ){
    $data[] = [
          'date' => $date,
          'charge'=>$value,
          'job_id'=>$job,
          'user_id'=>$id,
          'amount'=>$inputs['amount'][$key],
          'category'=>$inputs['amount'][$key],
    ];
}

希望这有帮助。
