我正在使用Codeigniter 3.1.8和Bootstrap 4开发基本的博客应用程序。
该应用程序具有用户(作者)帐户。由于我显示了会话中的头像(header.php视图),因此在会话被销毁之前显示登录照片(头像)存在问题。
<?php if ($this->session->userdata('user_avatar')): ?> <img src="<?php echo base_url('assets/img/authors/') . $this->session->userdata('user_avatar'); ?>" class="avatar" /> <?php else: ?> <img src="<?php echo base_url('assets/img/authors/') . 'default-avatar.png' ?>" class="avatar" /> <?php endif ?>
在当时,这似乎是一个好主意,在显示更新问题之前,对虚拟形象显示进行简单而合理的实现。当然,必须承认,我必须注销并再次登录才能在网站标题中看到我的头像。 :(
在模型中,我有:
public function update_user($avatar, $id) { $data = [ 'first_name' => $this->input->post('first_name'), 'last_name' => $this->input->post('last_name'), 'email' => $this->input->post('email'), 'bio' => $this->input->post('bio'), 'avatar' => $avatar ]; $this->db->where('id', $id); return $this->db->update('authors', $data); }
在登录控制器中,我有:
public function login() { $this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email'); $this->form_validation->set_rules('password', 'Password', 'required|trim'); $this->form_validation->set_error_delimiters('<p class="error-message">', '</p>'); if ($this->form_validation->run()) { $email = $this->input->post('email'); $password = $this->input->post('password'); $this->load->model('Usermodel'); $current_user = $this->Usermodel->user_login($email, $password); // If we find a user if ($current_user) { // If the user found is active if ($current_user->active == 1) { $this->session->set_userdata( array( 'user_id' => $current_user->id, 'user_email' => $current_user->email, 'user_avatar' => $current_user->avatar, 'user_first_name' => $current_user->first_name, 'user_is_admin' => $current_user->is_admin, 'user_active' => $current_user->active, 'is_logged_in' => TRUE ) ); // After login, display flash message $this->session->set_flashdata('user_signin', 'You have signed in'); //and redirect to the posts page redirect('/'); } else { // If the user found is NOT active $this->session->set_flashdata("login_failure_activation", "Your account has not been activated yet."); redirect('login'); } } else { // If we do NOT find a user $this->session->set_flashdata("login_failure_incorrect", "Incorrect email or password."); redirect('login'); } } else { $this->index(); } }
什么是容易实现的错误修正?

根据codeigniter session文档,您可以使用类似以下的内容:
