类stdClass的对象无法转换为字符串CodeIgniter

类stdClass的对象无法转换为字符串CodeIgniter,codeigniter,Codeigniter,我想根据用户名获取用户名,并将其插入到不同的表中。这是我的控制器: $customer = strtoupper($this->input->post('cust_name')); $address = $this->input->post('address'); $category = $this->input->post('category'); $sales = ($this->input->post('si

我想根据用户名获取用户名,并将其插入到不同的表中。这是我的控制器:

    $customer = strtoupper($this->input->post('cust_name'));
    $address = $this->input->post('address');
    $category = $this->input->post('category');

    $sales = ($this->input->post('sic'));              
    $salesID = $this->user_model->getUserName($sales);       

    $result = $this->db->insert('customer', [        
        'cust_name' => $customer,
        'cust_address' => $address,
        'category' => $category,
        'user_id' => $salesID
    ]);
我的模型是:

public function getUserName($sales) {
    $this->db->select("user_id");
    $query = $this->db->get_where('user', ['name' => $sales]);
    return $query->row();
}
当我执行查询时,它总是说“类stdClass的对象无法转换为字符串”

这里是var_转储:

对象(stdClass)#22(1){[“用户id”]=>string(2)“15”}

打印:

stdClass对象([user\u id]=>15)


如何解决这个问题?谢谢

希望这对您有所帮助:

使用
对象如下:

  $salesID = $this->user_model->getUserName($sales);       

   $result = $this->db->insert('customer', [        
    'cust_name' => $customer,
    'cust_address' => $address,
    'category' => $category,
    'user_id' => $salesID->user_id  /* here is the change*/
  ]);
替代方法:返回
用户id
如下:

    public function getUserName($sales) {
       $this->db->select("user_id");
       $query = $this->db->get_where('user', ['name' => $sales]);
       return $query->row()->user_id;
    }
   /*then use it as you are using currently*/

尝试删除
$this->db->select(“用户id”)行相同的stdClass错误,这里是打印结果
stdClass对象([user\u id]=>15[name]=>admin[password]=>47840d48c90990005b6f6c332f1b667319fb592d0461f0e67931b20210e595b1[电子邮件]=>test@test.com[添加日期]=>0000-00-00:00:00[修改日期]=>0000-00-00:00:00)
尝试此操作以获取用户\u id$salesID->user\u id whoa。我用的是第一个,它正在工作。对我来说是新知识。谢谢你的好意,先生。我的荣幸,快乐
