php - 为什么每次向 MySQL 插入数据时都会出现此错误？

Question

每当我将整数值插入数据库时​​，我都会遇到这个问题，它看起来像这样

<h1>A Database Error Occurred</h1>
        <p>Error Number: 1366</p><p>Incorrect integer value: '
11' for column 'code' at row 1</p><p>INSERT INTO `company`(`code`, `Name`) 
                             VALUES('\n11', 'John')

我的代码在一个跨度中，我的名字是一个输入类型。有没有办法删除值中的\n？

附加代码

function insert_new_name()
        {

        $code = $this->input->get('code');
        $name = $this->input->get('name');

        $sSQL = "SELECT * FROM company WHERE code = ? or Name = ? AND `show` = 1"  ;
        $result = $this->db->query($sSQL, array($code, $name));
            if($result->num_rows() != 0)
                {
                 return json_encode('error');
                }
            else
                {
                $sSQL = "INSERT INTO `company`(`code`, `Name`) 
                         VALUES(?, ?) ";
                $result = $this->db->query($sSQL, array($code, $name));
                $id = $this->db->insert_id();
                $sSQLdisplay = "SELECT * FROM Name where id = '$id' ";
                $resultdisplay = $this->db->query($sSQLdisplay);
                $data = array();
                $row = $resultdisplay->row();
                    $data[] = Array($row->id);
                    $data[] = Array($row->code);
                    $data[] = Array($row->Name);
                    $data[] = Array('');                        
                    $data[] = Array(''); 
                $resultdisplay->free_result();
                return json_encode($data);  
            }
        }

看起来您正在尝试将字符串 '\n11' 插入到需要整数的字段中。您需要从要插入的 code 值中去除非数字字符并将其解析为整数，以执行以下命令:

INSERT INTO `company`(`code`, `Name`) VALUES(11, 'John')
