我成功上传了数据库中的图像。但是没有成功从数据库中获取图像。 我想从数据库中获取图像。
这是我的代码， 控制器 - ＆gt;的login.php
public function user_update(){
$this->load->model('login_model');
$this->form_validation->set_rules('fname', 'First Name','required');
$this->form_validation->set_rules('lname', 'Last Name','required');
$this->form_validation->set_rules('cnumber', 'Contact Number','required|min_length[10]|max_length[10]|numeric');
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'doc|docx|pdf|gif|jpg|png|xlsx';
$config['max_size'] = 10000;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if (( ! $this->upload->do_upload('image')) && ($this->form_validation->run() === FALSE ))
{
$this->load->view('student/home');
}
else
{
$data = array('upload_data' => $this->upload->data());
$image_name=($data['upload_data']['file_name']);
$resume=base_url().$image_name;
$udata = array(
'id' => $this->input->post('id'),
'fname' => $this->input->post('fname'),
'mname' => $this->input->post('mname'),
'lname' => $this->input->post('lname'),
'email' => $this->input->post('email'),
'address' => $this->input->post('address'),
'cnumber' => $this->input->post('cnumber'),
'image'=> $resume
);
$this->login_model->Updateuser($udata);
}
}
模型文件： - login_model.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class login_model extends CI_Model
{
function Updateuser($param) {
$id = $param['id'];
$usar1 = array(
'Student_Name' => $param['fname'],
'm_name' => $param['mname'],
'l_name' => $param['lname'],
'Student_Email' => $param['email'],
'contact_no' => $param['cnumber'],
'Address' => $param['address'],
'image' => $param['image']
);
$this->db->where('Student_id', $id);
$this->db->update('students', $usar1);
//echo ($this->db->last_query());
//exit();
$sturesult = $this->login_model->get_student_list();
$data['Stulist'] = $sturesult;
$this->load->view('student/default_list',$data);
}
}

确定将代码放入您的视图文件中：
<img src="<?php echo base_url('uploads/').$Stulist[$i]->image; ?>"
答案 1 :(得分：0)
您已在数据库中更新了上传图像的错误图像目录。
只需更新以下代码行
即可$data = array('upload_data' => $this->upload->data());
$image_name=($data['upload_data']['file_name']);
$resume=base_url().$image_name;
到
$data = array('upload_data' => $this->upload->data());
$image_name=($data['upload_data']['file_name']);
$resume=base_url('uploads').$image_name;
这里base_url指向您上传图片的上传目录。
