（非法字符串偏移量）用于将数据导入数据库

Question

我正在尝试将 excel 导入我的数据库 table 'barangs'，但它有一个错误 "Illegal string offset 'kode_barang'"。我不知道如何修复此错误。

使用 laravel maatwebsite

将数据从 excel 导入数据库

我的控制器

public function import(Request $request)
    {
      $this->validate($request,[
        'select_file' => 'required|mimes:xls,xlsx'
      ]);
      $path = $request->file('select_file')->getRealPath();
      $data = Excel::load($path)->get();
      if ($data->count() > 0) {
        foreach ($data->toArray() as $key => $value) {
          foreach ($value as $row) {
            $insert_data[] = array(
              'kodeBarang'  => $row['kode_barang'],
              'namaBarang'  => $row['nama_barang'],
              'stock'       => $row['stock'],
              'hargaJual'   => $row['harga_jual'],
              'kategory'    => $row['kategory']
            );
          }
        }
        if (!empty($insert_data)) {
          barang::table('barangs')->insert($insert_data);
        }
      }
      return back()->with('success','berhasil di upload');
    }

我收到这样的错误消息

Illegal string offset 'kode_barang'

in barangController.php line 55 at HandleExceptions->handleError(2, 'Illegal string offset \'kode_barang\'', 'C:\xampp\htdocs\penjualan\app\Http\Controllers\barangController.php', 55, array('request' => object(Request), 'path' => 'C:\xampp\tmp\phpE998.tmp', 'data' => object(RowCollection), 'key' => 0, 'value' => array('kode_barang' => 331211, 'nama_barang' => 'coba import', 'stock' => 2, 'harga_jual' => 3000, 'kategory' => 'Minuman', null), 'row' => 'coba import', 'insert_data' => array(array('kodeBarang' => null, 'namaBarang' => null, 'stock' => null, 'hargaJual' => null, 'kategory' => null))))

Answer 1

您可以使用以下代码解决此问题。

    foreach ($data->toArray() as $key => $value) {
      foreach ($value as $row_key => $row) {
        $insert_data[] = array(
          'kodeBarang'  => $row[0],
          'namaBarang'  => $row[1],
          'stock'       => $row[2],
          'hargaJual'   => $row[3],
          'kategory'    => $row[4]
        );
      }
    }

Answer 2

添加条件以检查 null 行。

foreach ($data->toArray() as $key => $value) {
  foreach ($value as $row_key => $row) {
    if(!isset($row[0])) {
      $insert_data[] = array(
        'kodeBarang'  => $row[0],
        'namaBarang'  => $row[1],
        'stock'       => $row[2],
        'hargaJual'   => $row[3],
        'kategory'    => $row[4]
      );
    }
  }
}

或

foreach ($data->toArray() as $key => $value) {
  foreach ($value as $row_key => $row) {
    if(!isset($row['kode_barang'])) {
      $insert_data[] = array(
        'kodeBarang'  => $row['kode_barang'],
        'namaBarang'  => $row['nama_barang'],
        'stock'       => $row['stock'],
        'hargaJual'   => $row['harga_jual'],
        'kategory'    => $row['kategory']
      );
    }
  }
}
