php - 消息 : Object of class stdClass could not be converted to string in codeigniter

Question

当我运行下面的代码时

  $data = array(
                'name' => $this->input->post('name'),
                'recipe' => $this->input->post('recipe'),
                'category_id' => $category_id,
                'recipe_elements' => $this->input->post('recipe_elements'),
                'country' => $this->input->post('country'),
                'video' => $this->input->post('video'),
                'img' => $img_name,
                'vote' => $this->input->post('oy')
            );

            $this->db->insert('recipes',$data);

我收到这个错误

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' '

我已经尝试更改输入值，但仍然出现相同的错误。任何帮助，将不胜感激。我该如何解决这个问题？

Answer 1

您正在尝试将 object 转换为 string。请确保 $category_id 和 $img_name 不是一个对象。

看看这里，这可能对您有所帮助。 Object of class stdClass could not be converted to string

您可以 sse:$this->db->last_query(); 返回最后运行的查询(查询字符串，而不是结果)。从那里您可以轻松地看到您的查询字符串，这也有助于您找出实际错误。
