Question

我是编码的初学者。我在CI验证方面遇到问题，它总是返回false。This is the picture

这是我的控制器： `

//session_start();

Class Home extends CI_Controller {

    public function __construct() {
        parent::__construct();

        // Load database
        $this->load->model('login_pegawai');
    }

    // Show login page
    public function index() {
        $this->load->view('utama');
    }

    // Check for employee login process
    public function process() {

        $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
        $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean');

        if ($this->form_validation->run() == FALSE) {
            if(isset($this->session->userdata['logged_in'])){
                $this->load->view('pegawai/dashboard_pegawai');
            } else {
                $this->load->view('utama');
            }
        } else {
            $data = array(
                'username' => ($this->input->post('username')),
                'password' => md5($this->input->post('password'))
            );
            $result = $this->login_pegawai->login($data);
            if ($result == TRUE) {

                $username = $this->input->post('username');
                $result = $this->login_pegawai->read_user_information($username);
                if ($result != false) {
                    $session_data = array(
                        'username' => $result[0]->username,
                        'email' => $result[0]->email,
                    );
                    // Add user data in session
                    $this->session->set_userdata('logged_in', $session_data);
                    $this->load->view('pegawai/dashboard_pegawai');
                }
            } else {
                $data = array(
                    'error_message' => '<font color=red>Invalid username and/or password.</font><br />'
                );
                $this->load->view('utama', $data);
            }
        }
    }
}

和我的模特：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

Class Login_pegawai extends CI_Model {

    // Read data using username and password
    public function login($data) {

        $condition = "username =" . "'" . $data['username'] . "' AND " . "password =" . "'" . md5($data['password']) . "'";
        $this->db->select('*');
        $this->db->from('pegawai');
        $this->db->where($condition);
        $this->db->limit(1);
        $query = $this->db->get();

        if ($query->num_rows() == 1) {
            return true;
        } else {
            return false;
        }
    }

    // Read data from database to show data in employee page
    public function read_user_information($username) {

        $condition = "username =" . "'" . $username . "'";
        $this->db->select('*');
        $this->db->from('pegawai');
        $this->db->where($condition);
        $this->db->limit(1);
        $query = $this->db->get();

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

我尝试了很多方法，但结果显示我一样。请让我知道我哪里弄错了。对不起说/写坏英语，谢谢。

将此替换为您的登录功能，当where子句中有多个条件时，也应定义第二个和第三个参数。

public function login($data) {

        $this->db->select('*');
        $this->db->from('pegawai');
        $this->db->where("username",$data['username']);
        $this->db->where("password",$data['password']);
        $this->db->limit(1);
        $query = $this->db->get();

        if ($query->num_rows()>0) {
            return true;
        } else {
            return false;
        }
    }

Codeigniter验证始终返回false
