使用 Laravel 将动态生成的表单输入插入 MySQL 数据库 [重复]

Question

我有一个用于向系统添加支票的表格。表格有两部分；第一部分是通用信息，即客户详细信息，第二部分是唯一详细信息，即检查详细信息。通过单击为表单生成重复输入的添加按钮，可以为同一用户添加多个检查。 使用 Laravel 将数据保存到 mysql 数据库时，出现错误

"未定义的偏移量：1"

这是我的 laravel 控制器：

public function store(Request $request)
{
  $customer_name = $request->customer_name;
  $cheque_number=$request->cheque_number;
  $count = count($cheque_number);

    for($i = 0; $i < $count; $i++){
        $objModel = new Cheque();
        $objModel->customer_name = $customer_name[$i];
        $objModel->cheque_number = $cheque_number[$i];
        $objModel->save();
    }
}

我的主要挑战是每个支票号码都应该保存在一个新行上，但要使用相同的客户名称，并且只提供一次。

Answer 1

试试这个

public function store(Request $request)
{
  $customer_name = $request->customer_name;
  $cheque_number = $request->cheque_number;
  $count = count($cheque_number);

    for($i = 0; $i < $count; $i++){
       if(isset($cheque_number[$i])) {  //for check value is set or not..
          $objModel = new Cheque();
          $objModel->customer_name = $customer_name;  //same name
          $objModel->cheque_number = $cheque_number[$i]; //different number
          $objModel->save();  
       }
    }
}

Answer 2

public function store(Request $request){
 $customer_name = $request->get('customer_name');
 $cheque_number = $request->get('cheque_number');
 $count = count($cheque_number);

 for($i = 0; $i < $count; $i++){
  if(isset($cheque_number[$i])){
   $objModel = new Cheque();
          $objModel->customer_name = $customer_name;  //same name
          $objModel->cheque_number = $cheque_number[$i]; //different number
          $objModel->save(); 
  }
 }
}

你应该试试这个：

public function store(Request $request)
{
  $customer_name = $request->customer_name;
  $cheque_number = $request->cheque_number;
  $count = count($cheque_number);

    for($i = 0; $i < $count; $i++){
       if(isset($cheque_number[$i])) {  
          $objModel = new Cheque();
          $objModel->customer_name = $customer_name;  //same name
          $objModel->cheque_number = $cheque_number[$i]; //different number
          $objModel->save();  
       }
    }
}
