I am working on a basic blog application with Codeigniter 3.1.8 and Bootstrap 4.
The application has user (author) accounts. There is a problem with displaying the photo (avatar) of the logged-in before the session is destroyed, due to the fact that I display the avatar from the session (header.php view):
Code:
<?php if ($this->session->userdata('user_avatar')): ?>
<img src="<?php echo base_url('assets/img/authors/') . $this->session->userdata('user_avatar'); ?>" class="avatar" />
<?php else: ?>
<img src="<?php echo base_url('assets/img/authors/') . 'default-avatar.png' ?>" class="avatar" />
<?php endif ?>
That seemed like a good idea at the time, an easy and logical implementation of the avatar display, until the update problem revealed. Of course, I have to logout and login again to see my avatar in the website's header, as I had to admit. 
In the model I have:
Code:
public function update_user($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);
}
In the Lofin controller I have:
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();
}
}
What would be an easy to implement bugfix?
