    $user_id = $this->uri->segment(3);

    $data['users'] = $this->Mpages->call_point_users($user_id);

    foreach($users as $users_item) {            
        $encrypt_pass = $users_item['password'];            
        $plain_pass = $this->encrypt->decode($encrypt_pass);            
    }

    $this->load->view('editusers', $data, $plain_pass); 


}

Answer 1

将$ plain_pass放入数据数组中。

public function editusers() { 

    $user_id = $this->uri->segment(3);

    $data['users'] = $this->Mpages->call_point_users($user_id);

    foreach($users as $users_item) {            
        $encrypt_pass = $users_item['password'];            
        $plain_pass = $this->encrypt->decode($encrypt_pass);            
    }

    $data['plain_pass'] = $plain_pass; 

    $this->load->view('editusers', $data); 

}

Answer 2

我找到的最佳方式

 $data['users'] = array();

 $results = $this->Mpages->call_point_users($user_id);

 if (isset($results)) {

 foreach ($results as $result) {
    $data['users'][] = array(
       'email' => $result['email'],
       'username' => $result['username'],
       'encrypt_pass' => $result['password'], 
       'plain_pass' => $this->encrypt->decode($result['encrypt_pass'])
    );
 }

 }

 $this->load->view('someview', $data);

没有两种类型的通行词只有一种。还有codeigniter   加密不是密码的代码，因为它可以被解密，   而是使用像
这样的东西
http://php.net/manual/en/function.password-hash.php并进行验证   http://php.net/manual/en/function.password-verify.php varchar 255
