php实战第六天

今天学习了做后台页面，很失败就不展示了。

php方面：以下代码可以屏蔽php注意级别的错误，即 抛出任何非注意错误

[php] error_reporting(E_ALL&~E_NOTICE);

error_reporting(E_ALL&~E_NOTICE);
开启session的方法，开启后就可以使用$_SESION咯。

session是保存在服务端的东西噢。启动后会给 浏览器发送一个 session的ID，是cookies方式的

[php] session_start();

session_start();
如果浏览器禁用了cookies那也不要紧，可以把session写到URL里就好咯.嘿嘿

[php] session_name.'='.session_id()

session_name.'='.session_id() 附上我写好的 adminAction，只有登陆功能哦

[php] /**
*
**/
class adminAction extends Action
{
protected $db='';
function __construct()
{
// code...
// //$smarty->force_compile = true;
/*$this->db = new MySQL("127.0.0.1","root","1234","myly","data");
$this->db->table('data');*/
$this->db = MySQL::getClass();
//var_dump($this->db);
$this->db -> connect("127.0.0.1","root","1234","myly");

$this->db -> table('user');

parent::__construct();
}

public function index()
{
if($this->is_login()){
echo "";
}else{
echo "";
}
}

private function is_login()
{
return $_SESSION['login'];

}

public function login()
{
if (!empty($_POST['userName']) && !empty($_POST['password'])) {
$userName=$_POST['userName'];
$password=md5($_POST['password']);
/*var_dumP($_POST);
var_dump($password);
var_dump($password);*/
if($_SESSION['userData']=$this->db->where("userName='{$userName}' and password='{$password}'")->fine()){
echo "";
$_SESSION['login']=true;

}else{

echo "登录失败";
}
}

$this->display();
}

public function ulogin()
{
echo "";
unset($_SESSION);
}

public function admin()
{
if(!$this->is_login()){
echo "";
}
//var_dump($_SESSION);
$this->assign('userName',$_SESSION['userData']['userName']);
$this->display();
}

function add(){
/*var_dump($this->db
->data(
array('userName' => 'admin',
'password' => md5('admin'),
'time' => time()
))
->add());
*/
}

}
?>

提交表单用的 login.html
[html]

登陆成功后用的 admin.html

[html]

这个就是我的登陆功能了。

修改了 mysql.class.php 加了一个函数 fine，这样返回的数组就是 一维的咯，方便些

[php] /**
+----------------------------------------------------------
* 获取数据表的单条记录，返回一维数组
+----------------------------------------------------------
* @access public
+----------------------------------------------------------
* @param
+----------------------------------------------------------
*/
public function fine(){
$select_sql = 'select ';
$fields = isset($this->query_list['fields'])?$this->query_list['fields']:'*';
$select_sql.=$fields;
$select_sql.= ' from `'.$this->query_list['table'].'` ';

isset($this->query_list['join'])?($select_sql.=$this->query_list['join']):'';
isset($this->query_list['where'])?($select_sql.=' where '.$this->query_list['where']):'';
isset($this->query_list['group'])?($select_sql.=' group by'.$this->query_list['group']):'';
isset($this->query_list['having'])?($select_sql.=' mysql having '.$this->query_list['having']):'';
isset($this->query_list['order'])?($select_sql.=' order by '.$this->query_list['order']):'';
isset($this->query_list['limit'])?($select_sql.=' 1,1'):'';
//echo '
----->'.$select_sql.'';
return $this->query($select_sql)[0];
}

/**

*/
public function fine(){
$select_sql = 'select ';
$fields = isset($this->query_list['fields'])?$this->query_list['fields']:'*';
$select_sql.=$fields;
$select_sql.= ' from `'.$this->query_list['table'].'` ';

isset($this->query_list['join'])?($select_sql.=$this->query_list['join']):'';
isset($this->query_list['where'])?($select_sql.=' where '.$this->query_list['where']):'';

//echo '
