Question

如何存储与提供的数量相同的数据？

例子

商店abc,10时代

两者abc都10来自表单请求

代码

nonuiqueAmount: 10
nonuiqueSerial: "abc"


 if(!empty($request->input('nonuiqueSerial'))) {
   foreach($request->input('nonuiqueAmount') as $item) { // this returns error
       $barcode = new Barcode;
       $barcode->serial_number = $request->input('nonuiqueSerial');
       $barcode->save();
   }
 }

您应该使用 for 循环：

// nonuiqueAmount: 10
// nonuiqueSerial: "abc"


if (!empty($request->input('nonuiqueSerial'))) {
    for ($i = 0; $i < $request->input('nonuiqueAmount', 0); ++$i) { // I've added the zero as a default value to prevent unnecessary loops
        $barcode                = new Barcode;
        $barcode->serial_number = $request->input('nonuiqueSerial');
        $barcode->save();
    }
}
