如何检查旧密码并将其更新为新密码？

Question

我的代码中没有发生任何事情。没有错误显示，但密码不变。点击提交按钮后，它只会重定向到password_view。

这里是我的密码查看：password_view.php

<?php echo form_open_multipart('password');?> 

    <div class="form-group"> 
     <label class="control-label col-lg-2"> Old Password:</label> 
      <div class="col-lg-4"> 
       <input class="form-control" name="oldPassword" placeholder="Old Password" type="password"> 
       <span class="text-danger"><?php echo form_error('oldPassword'); ?></span> 
      </div> 
    </div> 

    <div class="form-group"> 
     <label class="control-label col-lg-2"> New Password:</label> 
      <div class="col-lg-4"> 
       <input class="form-control" name="newPassword" placeholder="New Password" type="password"> 
       <span class="text-danger"><?php echo form_error('newPassword'); ?></span> 
      </div> 
    </div> 

    <div class="form-group"> 
     <label class="control-label col-lg-2"> Re-type Password:</label> 
      <div class="col-lg-4"> 
       <input class="form-control" name="renewPassword" placeholder="Re-type Password" type="password"> 
       <span class="text-danger"><?php echo form_error('renewPassword'); ?></span> 
      </div> 
    </div> 

    <div class="form-group"> 
     <label class="control-label col-lg-2"></label> 
      <div class="col-lg-4"> 
       <button type="submit" class="btn btn-primary btn-grad btn-rect">Submit</button> 
       <a href ="<?php echo base_url();?>index.php/main" class="btn btn-default btn-grad btn-rect">Cancel</a> 
      </div> 
    </div> 

<?php echo form_close(); ?> 

这里是我的密码控制器：password.php

public function index() 
{ 
    $this->form_validation->set_rules('oldPassword','Old Password','trim|required|min_length[5]|max_length[30]'); 
    $this->form_validation->set_rules('newPassword','New Password','trim|required|min_length[5]|max_length[30]'); 
    $this->form_validation->set_rules('renewPassword','Retype Password','trim|required|matches[newPassword]'); 

    if($this->form_validation->run() == FALSE) 
    { 
     $this->load->view('password_view'); 
    } 
    else 
    { 
     $this->load->model('account_model'); 
     $this->load->view('password_view'); 
     $query = $this->account_model->checkOldPassword($this->input->post('oldPassword')); 

     if($query) 
     { 
      $query = $this->account_model->saveNewPassword($this->input->post('newPassword')); 

      if($query) 
      { 
       $this->session->sess_destroy(); 
       $data['error']='Password Change Successfully. Please login to Continue.'; 
       $this->load->view('password_view',$data); 
      } 
      else 
      { 
       $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>'); 
       redirect('account/editPassword'); 
      } 
     } 
    } 
} 

这里是我的密码模式：account_model.php

public function checkOldPassword($oldPassword) 
{ 
    $this->db->select('AID'); 
    $this->db->where('AID',$this->session->userdata('id')); 
    $this->db->where('Password',$this->input->post('oldPassword')); 
    $query=$this->db->get('tblaccount'); 
    if($query->num_rows>0) 
    { 
     $row=$query->row(); 

     if($oldPassword == $row->Password) 
     { 
      return true; 
     } 
     else 
     { 
      return false; 
     } 
    } 
} 

public function saveNewPassword($newPassword) 
{ 
    $data = array(
      'Password' => $newPassword 
      ); 

    $this->db->where('AID', $this->session->userdata('id')); 
    $this->db->where('Password',$this->input->post('oldPassword')); 
    $query = $this->db->update('tblaccount', $data); 

    if($query) 
    { 
     return true; 
    } 
    else 
    { 
     return false; 
    } 
} 

Answer 1

更改旧密码规则

添加在旧密码字段

$this->form_validation->set_rules('oldPassword','Old Password','trim|required|min_length[5]|max_length[30]|callback_checkOldPassword'); 

变化checkOldPassword方法

组错误消息checkOldPassword规则callback_checkOldPassword规则

public function checkOldPassword($oldPassword) 
{ 
    $this->db->select('AID'); 
    $this->db->where('AID',$this->session->userdata('id')); 
    $this->db->where('Password',$this->input->post('oldPassword')); 
    $query=$this->db->get('tblaccount'); 
    if($query->num_rows>0) 
    { 
     return true; 
    }else{ 
     $this->form_validation->set_message('checkOldPassword', 'wrong old password.'); 
     return false; 
    }
