TP 框架:
1.MVC 设计模式
2.模板引擎
3.常用操作类

MVC 设计模式:
M model 数据模型
V view 视图
C control 控制器

控制器lib路由访问，一般
http://xxx.com/index.php/index/test

public function test(){
	echo "aaaaaa";
}

渲染模版视图view一般默认渲染tpl下的视图文件

public function test(){
	$this->display();
}

值传递渲染模版

public function test(){
	$this->assign("name","User1");
	$this->display();
}

<h1>{$name}</h1>

网站值传递

public function test(){
	echo $_GET["id"];
	$this->assign("name","User1");
	$this->display();
}

建议以第一个做值传递
http://www.xx.com/index.php/index/test/id/123

/index.php/index/test?id=123

全局常量渲染

<p>../Public</p> 
<p>__TMPL__</p> 
<p>__PUBLIC__</p>
<p>__ROOT__</p> 
<p>__APP__</p> 
<p>__URL__</p> 
<p>__ACTION__</p> 
<p>__SELF__</p>

配置默认控制器模块

<?php
return array(
	//'配置项'=>'配置值'
	'DEFAULT_MODULE'=>'User',
);
?>

common.php

<?php
function show(){
    echo "show aa";
}
?>

public function test(){
	// echo __ROOT__.'/Public/Images/sb.jpeg';;
	// echo $_GET["id"];
	show();
	$this->assign("name","User1");
	$this->display();
}

权限验证

<?php
class CommonAction extends Action {
  function _initialize(){
    echo "进行权限验证!";
  }

}

继承

<?php
// 本类由系统自动生成，仅供测试用途
class IndexAction extends CommonAction {
    public function index(){
    	$user=M('User');
    	$this->rows=$user->select();
    	$this->display();
    }

    public function del(){
    	$id=$_GET['id'];
    	$user=M('User');
    	if($user->delete($id)){
    		$this->success('删除成功',U('index'));
    	}
    }
    public function show(){
    	echo "<h1>aaaaaaaaaaa</h1>";
    }
	public function test(){
		// echo __ROOT__.'/Public/Images/sb.jpeg';
		// echo $_GET["id"];
		show();
		$this->assign("name","User1");
		$this->display();
	}
}

"URL_MODEL" => "2"

控制左右定界符: 

'TMPL_L_DELIM' => '<{', 
'TMPL_R_DELIM' => '}>',

获取路由访问

<h1><{:U()}></h1>

输出控制路由器

<h1><{:U("test")}></h1>

url重定向

$this->redirect('','',5,'页面跳转');

地址跳转: 
1.正确
本模块: 
$this->success('ok','show'); 
跨模块: 
$this->success('添加成功',U('User/index')); 
2.错误
本模块: 
$this->error('error','show');

自定义模块

$user = D("User")

插入

public function sqlselecgt(){
	echo "insert sql";
	$arr['id'] = '2';
	$arr['username'] = 'user3';
	$arr['password'] = '4566';
	$user = M("user");
	$user->add($arr);
}

映射和验证逻辑

protected $_auto=array(
    array('password','md5','3','function'),
);
protected $_validate=array(
    array('username','require','用户名不能为空'),
    array('username','checkUsername','用户名长度不正确',2,'callback'),
    array('password','require','密码不能为空'),
    array('codes','require','验证码不能为空'),
    array('codes','checkCode','验证码有误',2,'callback'),
    #array('fcode','Code','验证码有误',2,'callback'),
);
function checkCode($codes){
    if($codes!=$_SESSION['scode']){
        return false;
    }
}
function checkUsername($username){
    if(strlen($username)<6){
        return false;
    }

}
protected $patchValidate = true;

CURD操作

create
		$arr['username'] = '12312312451';
		$arr['password'] = 'abc123';
		$user = D("User");
		$user->create($arr);
		$user->add()

delete
		$user = M("User");
		$id = 1;
		$user->delete($id);

select
    	$user = M("User");
		$row = $user->select();
		echo "<pre>";
		print_r($row);
		echo "</pre>";
		
		$row = $user->where(array("id"=>$id))->select();
		echo "<pre>";
		print_r($row);
		echo "</pre>";

find
    		$row = $user->where(array("id"=>$id))->find();
		echo "<pre>";
		print_r($row);
		echo "</pre>";

update
		$user = M("User");
		$arr["id"] = 123123123;
		$arr["username"] = "myself";
		$arr["password"] = "admin123123";
		$user -> create();
		$user -> save();

过滤重复值查询

$user = M("User");
$user -> Distinct(true)->field('username')->select();
echo $user->getLastSql()

SELECT DISTINCT `username` FROM `user`

模块

class UserModel extends Model{
    protected $_map =array(
        'id' => 'id',
        'name' => 'username',
        'pass' => 'password',
    );
    protected $_auto=array(
        array('password','md5','3','function'),
    );
    protected $_validate=array(
        array('username','require','用户名不能为空'),
        array('username','checkUsername','用户名长度不正确',2,'callback'),
        array('password','require','密码不能为空'),
        array('codes','require','验证码不能为空'),
        array('codes','checkCode','验证码有误',2,'callback'),
        #array('fcode','Code','验证码有误',2,'callback'),
    );
    function checkCode($codes){
        if($codes!=$_SESSION['scode']){
            return false;
        }
    }
    function checkUsername($username){
        if(strlen($username)<6){
            return false;
        }

    }
    protected $patchValidate = true;
}

模版引用赋值

<!doctype html>
<html>
<head>
	<meta charset="UTF-8">
	<title>index</title>
</head>
<body>
	<h1>Index/index</h1>
	<h1><{$a+$b}></h1>

</body>
</html>

  public function index(){
  	// $user=M('User');

  	// $this->rows=$user->select();
  	// $this->display();
$this->a = 10;
$this->b = 20;
$this->display();
  }

for循环

<for start="1" end="10">
	<h1><{$i}></h1>
</for>

判断

<if condition='$i==2'>
	<h1><{$i}></h1>
</if>

循环

<foreach name='rows' item='val'>
	<h1><{$val.username}></h1>
</foreach>

登陆

$user = M('User');
$_POST['password'] = $_POST['password'];
$row = $user->where($_POST)->find();
if($row){
	session('username',$_POST['username']);
	session('login',1);
	$this->success('登陆成功','login');
}else{
	$this->error('登陆错误','login');
}
