Laravel 5.4 Query Builder Array转换为字符串

Question

我正在尝试使用laravel 5.4命令从Excel导入数据。我可以收集所有数据，现在我正在尝试插入数据库但我得到一个奇怪的错误。

这是发生错误的代码片段：

$data = [
            'name' => $row['name'],
            'address' => $row['address'],
            'suite' => $row['suite'],
            'city' => $row['city'],
            'zipcode' => $row['zipcode'],
            'country_code' => $row['country_code'],
            'province_code' => $row['province_code'],
            'region_id' => $region_id,
            'phone' => $row['phone'],
            'fax' => $row['fax'],
            'website' => $row['website'],
            'linkedin' => $row['linkedin'],
            'facebook' => $row['facebook'],
            'twitter' => $row['twitter'],
            'number_employees' => $row['number_employees'],
            'year_creation' => $row['year_creation'],
            'turnover_id' => $turnover_id,
            'status' => 1,
            'hidden_directory' => 0,
            'hidden_directory_byadmin' => 0,
            'is_member' => $row['is_member'],
            'created_by' => 1,
        ];

        $company = Company::create($data);

这是错误：

   Array to string conversion (SQL: insert into `company` (`name`, `address`, `suite`, `city`, `zipcode`, `country_code`, `province_code`, `region_id`, `phone`, `fax`, `website`, `lin  
  kedin`, `facebook`, `twitter`, `number_employees`, `year_creation`, `turnover_id`, `status`, `hidden_directory`, `created_by`, `updated_at`, `created_at`) values (Test Company 3, 1  
  315 Rue St-Louis, , Montreal, H4L 2P4, CA, QC, , [phone], [phone], http://www.google.com, https://www.linkedin.com/feed/, https://www.facebook.com/, https://twitt  
  er.com/, 200, 2010, , 1, 0, 1, 2019-03-27 09:48:29, 2019-03-27 09:48:29)) 

这就像它缺少SQL插入查询中的刻度。奇怪的是，我在系统的其他部分执行相同的插入，但这不会发生。

我不是想在这里插入JSON。是的，我在StackOverflow中看到了所有类似的问题，当你试图插入json但不是常规字符串和整数时，这种情况很常见。

我在这里做错了什么？

谢谢你的帮助。

基本上，$row中的指数是array，而不是string或int，正如预期的插入。由于这可能是任何索引，因此最好使用带有try/catch逻辑的DB::transaction()块来避免此错误：

\DB::beingTransaction();

try {
    $data = [
        'name' => $row['name'],
        'address' => $row['address'],
        'suite' => $row['suite'],
        'city' => $row['city'],
        'zipcode' => $row['zipcode'],
        'country_code' => $row['country_code'],
        'province_code' => $row['province_code'],
        'region_id' => $region_id,
        'phone' => $row['phone'],
        'fax' => $row['fax'],
        'website' => $row['website'],
        'linkedin' => $row['linkedin'],
        'facebook' => $row['facebook'],
        'twitter' => $row['twitter'],
        'number_employees' => $row['number_employees'],
        'year_creation' => $row['year_creation'],
        'turnover_id' => $turnover_id,
        'status' => 1,
        'hidden_directory' => 0,
        'hidden_directory_byadmin' => 0,
        'is_member' => $row['is_member'],
        'created_by' => 1,
    ];

    $company = Company::create($data);

    \DB::commit();
} catch(\Exception $ex){
   \Log::error("Error in Company::create(): ".$ex->getMessage());
   \DB::rollBack();
}

如果你不确定$row[...]可以包含什么，并且有可能出现array /无效值，那么使用像这样的try/catch会阻止插入问题，并且只在没有遇到错误时才最终确定插入。除此之外，您需要确保插入的数据符合您的预期。

你可以像这样做字符串的样式转换

$data = [
    'name' => (string)$row['name'],
    'address' => (string)$row['address'],
    'suite' => (string)$row['suite'],
    'city' => (string)$row['city'],
    'zipcode' => (string)$row['zipcode'],
    'country_code' => (string)$row['country_code'],
    'province_code' => (string)$row['province_code'],
    'region_id' => $region_id,
    'phone' => (string)$row['phone'],
    'fax' => (string)$row['fax'],
    'website' => (string)$row['website'],
    'linkedin' => (string)$row['linkedin'],
    'facebook' => (string)$row['facebook'],
    'twitter' => (string)$row['twitter'],
    'number_employees' => (string)$row['number_employees'],
    'year_creation' => (string)$row['year_creation'],
    'turnover_id' => $turnover_id,
    'status' => 1,
    'hidden_directory' => 0,
    'hidden_directory_byadmin' => 0,
    'is_member' => (bool)$row['is_member'],
    'created_by' => 1,
];

$company = Company::create($data);

OR而不是字符串，您可以使用int / float。这将以字符串格式保存您的数据。
