这是我的错误
发生数据库错误
错误号码:1064
您的SQL语法有错误;查看与您的MariaDB服务器版本对应的手册,以获得正确的语法,以便在“" SET`_ last_activity` = 1475713773,`user_data` =' a:2:{s:9:\" USER_DATA \&#34 ;; S:0:\" \"'在第1行
UPDATE SET`last_activity` = 1475713773,`user_data` =' a:2:{s:9:\" user_data \&#34 ;; s:0:\" \ &#34 ;; S:6:\"用户ID \&#34 ;; S:1:\" 1 \&#34 ;;}'在哪里`session_id` =' 738744d19c2e9e582af4afb59826e331'

这是我的控制者:
function login(){
$data['error']=0;
if($_POST){
$this->load->model('user');
$username=$this->input->post('username',true);
$password=$this->input->post('password',true);
$user=$this->user->login($username,$password);
if(!$user){
$data['error']=1;
} else {
$this->session->set_userdata('userID',$user['userID']);
//$this->session->set_userdata('user_type',$user['user_type']);
redirect(base_url().'posts');
}
}
$this->load->view('header');
$this->load->view('login',$data);
$this->load->view('footer');
}
这是我的模特:
function login($username,$password){
$where=array(
'username'=>$username,
'password'=>$password
);
$this->db->select()->from('users')->where($where);
$query=$this->db->get();
return $query->row_array('array');
}
我的问题是我可以检测到无效的用户名和密码,但如果我使用有效的用户名和密码,则会出现上述错误。
答案 0 :(得分:0)
注意到代码中存在多个错误。将模型修改为(<div id="response_wrapper">
<div id="timer_response"></div>
<div id="remaining_response"></div>
</div>
repeatAjax();
function repeatAjax(){
$.ajax({
type: "GET",
url: "get_feed.php",
dataType: "html",
success: function(response, status) {
$("#remaining_response").html(response);
},
complete: function() {
setTimeout(repeatAjax,3000);//comment this line of code if you want to prevent further refreshing of image and username
}
});
};
repeatAjax2();
function repeatAjax2(){
$.ajax({
type: "GET",
url: "get_feed.php?&tm=true",
dataType: "html",
success: function(response, status) {
$("#timer_response").html(response);
},
complete: function() {
setTimeout(repeatAjax2,1000);
}
});
};
和select()
问题)
row_array()
最后确保你的`ci_sessions&#39;表格创建为
function login($username,$password){
$where = array(
'username'=>$username,
'password'=>$password
);
$this->db->select('*')->from('users')->where($where);
$query=$this->db->get();
return $query->row_array();
}
看到这不是CREATE TABLE IF NOT EXISTS `ci_sessions` (
`id` varchar(40) NOT NULL,
`ip_address` varchar(45) NOT NULL,
`timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
`data` blob NOT NULL,
KEY `ci_sessions_timestamp` (`timestamp`)
);
而是session_id
