删除密码而不是重置密码

早上好，有人可以帮我一下我有一个Iam未能掌握的小错误。我想更新/更改用户电子邮件地址的密码=例如123 @ gmail。然而，当我输入新密码时，它将删除旧密码并将该字段留空。删除密码而不是重置密码

**Controller** 
     <?php 
class My_account extends CI_Controller{ 
public function index(){ 
    $this->load->view("vChangePassword"); 
} 

public function change_password() 
{ 

    $this->load->library('form_validation'); 

    $this->form_validation->set_rules('cur_password','Current Password','required'); 
    $this->form_validation->set_rules('new_password','New Password','required'); 
    $this->form_validation->set_rules('con_password','Confirm Password', 'required[matches[new_password]'); 
    if ($this->form_validation->run()!= true){ 

     $this->load->view("vChangePassword"); 
    }else { 
     $sql = $this->db->select("*")->from('users')->where('email',$this->session->userdata('email'))->get(); 
    foreach($sql->result() as $my_info) 
    { 
     $db_password = $my_info->password; 
     $email = $my_info->email; 
    } 
     if(md5($this->input->post('cur_password'))== $db_password){ 
     $fixed_password = mysql_real_escape_string(md5($this->input->post('new_password'))); 
     // $update = $this->db->query("Update 'users' SET 'password' = '$fixed_password' WHERE 'id' = '$db_id'") or die(mysql_error()); 
     $fixed_password ='password'; 
     // $fixed_password = md5($this->input->post('new_password')); 
     $this->db->where('email', $email)->update('users' ,$fixed_password); 
     // $update = $this->db->query("Update 'users' SET 'password' = '$fixed_password' WHERE 'id'= '$db_id'")or die(mysql_error()); 
     echo "Password has been updated!" ; 

     } 
     else { 
      echo "Password is incorrect!"; 
     } 
    } 


} 
} 


?>

问题是你没有做出正确的阵列来更新密码，而不是要更新所生成的MD5串到

$ fixed_password ='password';错

试试这个

$fixed_password = mysql_real_escape_string(md5($this->input->post('new_password'))); 
$data = array('password' => $fixed_password); 

$this->db->where('email', $email); 
$this->db->update('users', $data)
