public function profil_guncelle($data, $id){
        $this->db->set($data);
        $this->db->where('id', $id);
        if ($this->db->update('users') ===true) {

首先设置$picture成为'' if $_FILES['avatar']['name']为空。

比尝试更新数据时

$data=array(
'user_pass' => $this->input->post('user_pass'),
'user_mail' => $this->input->post('user_mail'),
'avatar' => $picture
);

当然，如果图像文件为空，$ picture将设置为''。你更改数组变为：

$data=array(
        'user_pass' => $this->input->post('user_pass'),
        'user_mail' => $this->input->post('user_mail'),
      );
if($picture != ''){
    $data['avatar'] = $picture;
}
