Question

我是laravel的新手，基本上，当我使用codeigniter时，此代码可以正常工作。问题是我无法将其用于插入数据。

for($count = 0; $count < sizeof($cid); $count++){
inset to table for item 1,
inset to table for item 2, 
inset to table for item 3,
}

这是我的控制器

   $request->validate([
        'pembelian_kode' => 'required',
        'barang_kode' => 'required',
        'pembelian_total' => 'required',
        'pembelian_qty' => 'required',
        'supplier_id' => 'required',
      ]);

      $cid = Input::POST('cid');
      $cg = PembelianModel::create($request->all());

      if($cg){
        for($count = 0; $count < sizeof($cid); $count++){
          DB::table('pembelian_details')->insert([
            'pembelian_kode' => $request['pembelian_kode'], 'barang_kode' => $request['barang_kode'], 'pd_qty' => $request['pembelian_qty']]
          );
        }
      }
      return redirect()->route('pembelians.index')
      ->with('success','Data berhasil ditambah');

reults error 
Array to string conversion (SQL: insert into `pembelian_details` (`pembelian_kode`, `barang_kode`, `pd_qty`) values (PBL1812025877, BRG10181125230, 10))

所以我有两个表1是'orders'也是'order_details'。对于表订单，已成功添加数据，但对于订单详细信息，仍然存在错误。

有人可以帮助我吗？

我刚刚修改了您的脚本。希望这会起作用

问题：

$request['barang_kode']

缺少索引

$ request是一个对象而不是数组

     $cid = $request->cid;
        $cg = PembelianModel::create($request->all());

        if($cg){
            for($count = 0; $count < count($cid); $count++){
                DB::table('pembelian_details')->insert([
                        'pembelian_kode' => $request->pembelian_kode[$count],
                        'barang_kode' => $request->barang_kode[$count],
                        'pd_qty' => $request->pembelian_qty[$count]
                    ]
                );
            }
        }
        return redirect()->route('pembelians.index')
            ->with('success','Data berhasil ditambah');

使用sizeof时Laravel数组到字符串的转换
