的Javascript
<script>
loginValidator = $('#login').validate({
errorClass: 'error1',
focusInvalid: false,
errorElement: "div",
rules: {
username: {
required: true,
email: true
},
password: "required"
},
messages: {
username: {
email: "Please Enter a Valid E-mail Id"
},
password: {
required: "Please Enter Your Password"
}
},
submitHandler: function (form) {
var email = $('#username').val();
var password = $('#password').val();
var url = "<pre> ?php echo site_url() ?></pre> /register/do_login";
$.ajax({
type: 'post',
url: url,
data: {'username': email, 'password': password},
dataType: 'html',
success: function (data) {
if (data == 0) {
$('.invalidlogin').html('Invalid Username or Password').css('color', 'red');
}
if (data == 1)
{
window.location.href = "<?php echo site_url(); ?>/home/landing_home";
return false;
}
if (data == 2)
{
window.location.href = "<?php echo site_url(); ?>/home/first_login_disclaimer";
}
}
});
}
});
</script>
Register.php - 控制器
<?php
function do_login() {
echo $result = $this->obj_users->check_login();
exit;
}
?>
为registration.php-模型
<?php
function check_login() {
$username = $this->input->post('username');
$password = $this->input->post('password');
$last_logged = date('Y-m-d H:i:s');
$salt = sha1($password);
$password = md5($salt . $password);
$this->db->where(array('email' => $username, 'password' => $password, 'status' => '1'));
$query = $this->db->get('registration');
$result = $query->result();
if (count($result) > 0) {
$first_login_status = $result[0]->first_login;
if ($first_login_status == '1') {
$datas = array('last_logged' => $last_logged);
$this->db->where(array('email' => $username));
$this->db->update('registration', $datas);
$this->session->set_userdata('user_id', $result[0]->id);
$this->session->set_userdata('user_type', $result[0]->user_type);
$this->session->set_userdata('ADMIN_NAME', $result[0]->name);
return "1";
} else {
$this->db->where(array('email' => $username, 'password' => $password, 'first_login' => '0', 'status' => '1'));
$query = $this->db->get('registration');
$result = $query->result();
$this->session->set_userdata('first_login_user_id', $result[0]->id);
$this->session->set_userdata('first_login_user_type', $result[0]->user_type);
$this->session->set_userdata('FIRST_LOGIN_ADMIN_NAME', $result[0]->name);
if (count($result) > 0) {
return "2";
}
}
} else {
return "0";
}
}
?>
这里，ajax请求花了5秒多的时间来响应请求并重定向到下一页..请建议我是否有办法减少Ajax响应时间。谢谢。
