php - 使用 codeigniter 将出价放入出价表中

Question

我正在尝试构建一个投标应用程序。我想将文本字段与输出行的主键相关联。例如文本字段是 bid_amount 。当您输入出价金额时，我希望输入的出价金额以及出价者(卡车ID)和出价产品(行李ID)存储在出价表中。输出的要投标的产品存储在另一个表(寄售表)中，下面是我的模型、 View 和 Controller 。

以下是出现的错误

发生数据库错误

Error Number: 1054
Unknown column 'Array' in 'field list'
UPDATE `bids` SET `luggage_id` = NULL, `bid_amount` = Array, `truckerid` = '84K7B7'
Filename: models/Truckeraccount_model.php
Line Number: 129

遇到 PHP 错误

Severity: Notice
Message: Array to string conversion
Filename: database/DB_driver.php
Line Number: 1524

下面是我的模型、 View 和 Controller 。

Controller

 public function bid(){


                        $this->load->model('Truckeraccount_model');
                      //  $luggage_id = $this->uri->segment(3);
                        $this->Truckeraccount_model->bid();
                        redirect('truckeraccount_ctrl');

   } 

型号

function bid(){  

                        $data = array(

                        'luggage_id' => $this->input->post('luggage_id'),
                        'bid_amount' => $this->input->post('bid_amount'),
                        'truckerid' => $this->input->post('truckerid')
                        );
                        //$this->db->where('luggage_id', $luggage_id);
                        $query=$this->db->update('bids', $data);
                        return $query;  

    }

Answer 1

错误出现在表单的bid_amount[$row->luggage_id]部分。字段名称中不能包含第三个括号，如果写入，它将被视为数组。
