Php 密码功能不允许访问

我正在使用CodeIgniter-2014年4月12日的最新版本

我正在尝试将密码功能写入我的网站，用于公司登录门户。门户还没有编写，只是功能而已。它会显示，不会给我任何错误，除了无效密码的错误。我不知道问题出在哪里。因此，我包括所有适用的资源

更新！我发现了问题所在，现在我只需要知道如何以正确的方式解决它。在我的型号上，我使用MD5加密了密码。在运行探查器并看到从数据库或应用程序生成并发送加密密码后，我关闭了该功能，我不确定。无论如何，在那之后，密码让我通过，并在需要时拒绝访问。我如何保存加密

    <?php

class Company_user extends CI_Model {
    function login($username, $password){
        $this->db->select('company_user_id, username, password');
        $this->db->from('company_user');
        $this->db->where('username', $username);
        $this->db->where('password', MD5($password));
        $this->db->limit(1);

        $query = $this->db->get();

        if($query->num_rows() == 1) {
            return $query->result();
        } else {
            return FALSE;

非常感谢您的帮助。

非常简单，只需将加密从模型中删除。

我已经发现一个错误，您可能会发现，但它不是解决方案；id应为Verifylogin控制器第55行的计算机用户id。
