CodeIgniter Ajax 不适合我。
这是我到目前为止所尝试的。
v_login.php
<script type="application/javascript">
$(document).ready(function() {
$('#submit').click(function() {
var form_data = {
username : $('#username').val(),
password : $('#password').val(),
ajax : '1'
};
$.ajax({
url: "<?php echo site_url('c_login/ajax_check'); ?>",
type: 'POST',
async : false,
data: form_data,
success: function(msg) {
$('#message').html(msg);
}
});
return false;
});
});
</script>
<div class="container">
<div class="jumbotron">
<?php
$attributes = array('class' => 'form-signin');
echo form_open('c_login', $attributes); ?>
<h2 class="form-signin-heading">VMS Login System</h2>
<input type="username" name="username" id="username" class="form-control" placeholder="Username" required autofocus>
<input type="password" name="password" class="form-control" placeholder="Password" required>
<input class="btn btn-primary" type="submit" id="submit" value="Login">
<input class="btn btn-primary" type="reset" value="Cancel">
<?php echo form_close(); ?>
<div id="message">
</div>
</div>
</div>
C_login.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class C_login extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->library('form_validation');
$this->load->helper('url');
}
function index() {
$this->load->view('include/header');
$this->load->view('v_login');
$this->load->view('include/footer');
}
function ajax_check() {
if($this->input->post('ajax') == '1') {
$this->form_validation->set_rules('username', 'username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'password', 'trim|required|xss_clean');
$this->form_validation->set_message('required', 'Please fill in the fields');
if($this->form_validation->run() == FALSE) {
echo validation_errors();
} else {
$this->load->model('m_access');
$user = $this->m_access->check_user($this->input->post('username'),$this->input->post('password'));
if($user == '1') {
echo 'login successful';
} else {
echo 'unknown user';
}
}
}
}
}
/* End of file c_login.php */
/* Location: ./application/controllers/c_login.php */
m_access.php
<?
class M_access extends CI_Model {
public function check_user($username,$password) {
$this->query = $this->db->select('COUNT(*)')->from('users')->where(array('username'=>$username,'password'=>$password))->limit(1)->get();
return $this->query->row_array();
}
}
不知道怎么回事,已经设置好config.php和路由了。但它根本不起作用。有任何想法吗?非常感谢您的帮助。谢谢。
