Php 如何使用CodeIgniter向数据库添加图像路径

如何使用CodeIgniter将图像路径添加到数据库中，到目前为止，我已经有了这个，我没有收到任何错误，但它没有将图像url添加到数据库中

这是我的个人资料控制器：

<?php
class Profile extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->helper(array('url', 'html', 'form'));
        $this->load->library(array('session', 'form_validation'));
        $this->load->database();
        $this->load->model('user_model');


    }

    function index()
    {
        $details = $this->user_model->get_user_by_id($this->session->userdata('uid'));
        $data['uname'] = $details[0]->firstname . " " . $details[0]->lastname;
        $data['uemail'] = $details[0]->email;
        $data['uimage'] = $details[0]->image;
        $this->load->view('profile_view', $data);

    }

    function delete()
    {
        $this->user_model->delete_row($this->session->userdata('uid'));
        redirect('Site/index');

    }

    function update()
    {

        $this->user_model->update($this->input->post("name"), $this->session->userdata('uid'));
        $this->user_model->update($this->input->post("email"), $this->session->userdata('uid'));
        $this->user_model->add_image($this->input->post('userfile'), $this->session->userdata('uid'));
        redirect('profile/index');

    }


    public function index1()
    {
        $this->load->view('profile_view', array('error' => ' '));
    }

    public function do_upload() {
        $config['upload_path']          = './assets/img';
        $config['allowed_types']        = 'gif|jpg|png';

        $this->load->library('upload', $config);


        $details = $this->user_model->get_user_by_id($this->session->userdata('uid'));
        $data['uname'] = $details[0]->firstname . " " . $details[0]->lastname;
        $data['uemail'] = $details[0]->email;

        if ( ! $this->upload->do_upload('userfile'))
        {
            $data['error'] = $this->upload->display_errors();
            $this->load->view('profile_view', $data);
        }
        else
        {
            $upload_data = $this->upload->data();
            $data['image']= $upload_data['file_name'];
            $data['uid'] = $this->session->userdata('uid');
            $this->load->view('profile_view', $data);
        }

        }
    }

在更新模型中添加方法：

function add_image($uimage, $id){
    $this->db->where('id', $id);
    $this->db->set('image', $uimage);
    $this->db->update('user');
}

上传用户照片后，调用
add_image
方法：

public function do_upload() {
    $config['upload_path']          = './assets/img';
    $config['allowed_types']        = 'gif|jpg|png';
    $config['max_size']             = 100;
    $config['max_width']            = 1024;
    $config['max_height']           = 768;

    $this->load->library('upload', $config);


    $details = $this->user_model->get_user_by_id($this->session->userdata('uid'));
    $data['uname'] = $details[0]->firstname . " " . $details[0]->lastname;
    $data['uemail'] = $details[0]->email;

    if ( ! $this->upload->do_upload('userfile'))
    {
        $data['error'] = $this->upload->display_errors();
        $this->load->view('profile_view', $data);
    }
    else
    {       
        $upload_data = $this->upload->data(); 
        $images_name = $upload_data['file_name'];

        //update user photo intro database
        $this->user_model->add_image($images_name, $this->session->userdata('uid'));

        $data['upload_data'] = $upload_data;
        $data['uid'] = $this->session->userdata('uid')
        $this->load->view('profile_view', $data);
    }
}

解决了你的问题？
function add_image($uimage, $id){
    $this->db->where('id', $id);
    $this->db->set('image', $uimage);
    $this->db->update('user');
}

public function do_upload() {
    $config['upload_path']          = './assets/img';
    $config['allowed_types']        = 'gif|jpg|png';
    $config['max_size']             = 100;
    $config['max_width']            = 1024;
    $config['max_height']           = 768;

    $this->load->library('upload', $config);


    $details = $this->user_model->get_user_by_id($this->session->userdata('uid'));
    $data['uname'] = $details[0]->firstname . " " . $details[0]->lastname;
    $data['uemail'] = $details[0]->email;

    if ( ! $this->upload->do_upload('userfile'))
    {
        $data['error'] = $this->upload->display_errors();
        $this->load->view('profile_view', $data);
    }
    else
    {       
        $upload_data = $this->upload->data(); 
        $images_name = $upload_data['file_name'];

        //update user photo intro database
        $this->user_model->add_image($images_name, $this->session->userdata('uid'));

        $data['upload_data'] = $upload_data;
        $data['uid'] = $this->session->userdata('uid')
        $this->load->view('profile_view', $data);
    }
}
