先上demo

PHP复制代码

<body>

<div class='signup_container'>

<div id="signup_forms" class="signup_forms clearfix">
<form class="signup_form_form" id="signup_form" method="post" action="" data-secure-action="https://www.tumblr.com/login" data-secure-ajax-action="">
<div class="form_row first_row">

</div>
</form>
</div>

<div class="login-btn-set"><div class='rem'>记住我</div> <a id="login" class='login-btn'></a></div>
<p class='copyright'>版权所有</p>
</div>

</body>

<script type="text/javascript">

$(function(){

$('.rem').click(function(){
$(this).toggleClass('selected');
})

$('#signup_select').click(function(){
$('.form_row ul').show();
event.cancelBubble = true;
})

$('#d').click(function(){
$('.form_row ul').toggle();
event.cancelBubble = true;
})

$('body').click(function(){
$('.form_row ul').hide();
})

$('.form_row li').click(function(){
var v = $(this).text();
$('#signup_select').val(v);
$('.form_row ul').hide();
})

})

</script>

</html>

复制代码

视图里不包含任何php代码是用jquery提交给页面

JS复制代码

$(document).ready(function(){$("a#login").bind("click",enter);

function enter(){
name = $("#signup_name").val();
password = $("#signup_password").val();
param = {"name":name,"password":password};
$.ajax({
contentType:"application/x-www-form-urlencoded; charset=utf-8",
type:'post',
url:'index.php/admin/query', //提交给指定的方法
data:param,
async:false,
success: function(msg){
if(msg=="001"){
location.href ='home.php';
}else{
alert(msg);
//document.forms[0].action='http://www.1.cn';
}
}
});
};
});

复制代码

控制器

PHP复制代码

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class admin extends CI_Controller {

// 装载父类控制器
function __construct()
{
parent::__construct();
//$this->load->helper('url'); //已经被ci自动加载
//$this->load->library('session'); //已经被ci自动加载

}

public function index()
{
$this->load->helper('form');
$this->load->view('login');
}

public function query()
{
$this->load->model('Mlogin');
$query = $this->Mlogin->Select();
if($query)
{
$data = array(
'name' => $this->input->post('name'),
'is_logged_in' => true
);
//$ssoname = $this->input->post('name');
$this->session->set_userdata($data);
echo '22';
//echo $ssoname;
}

else
{
$this->index();
echo 'error';
}
}

}

复制代码

模型------

PHP复制代码

<?php
class Mlogin extends CI_Model{

function __construct(){

parent::__construct();
}

function Select()
{
//$this->load->database();
//$this->db->where('status=','5');
//$this->db->select('name');
//$query = $this->db->get('loginlog');
//$sql="select name,password from nasdaouser where 1=1 and loginstatus=0";
//$log=$this->db->query($sql,array(5));
//return $log->result();
$this->db->where('name',$this->input->post('name'));
$this->db->where('password',md5(base64_encode($this->input->post('password'))));
$query = $this->db->get('nasdaouser');
if($query->num_rows() == 1)
{
return true;
}

}
}

?>

复制代码

视图没有代码,是纯由jquery AJAX提交给指定的控制器

在点击登录后，检查session 看见已经写入,然后就出现500错误

问题已经解决,配置中被无意修改

		自动登录	找回密码
密码			入住 CI 中国社区
