This article describes the functions implemented by ThinkPHP in the form of examples, including user registration, login, and leaving messages. What you need to pay attention to here is that when instantiating a user class when there is a user model, use the D method to implement it.

UserActivion.class.php page:

<?php
class UserAction extends Action{
public function add(){
$user = D("user");
$user->create();
$result = $user->add();
if($result){
$this->assign("jumpUrl","__APP__/index/index");
$this->success(&#39;注冊成功！&#39;);
}else{
//echo $user->getError();
$this->assign("jumpUrl","__APP__/user/register");
$this->error($user->getError());
}
}
public function register(){
$this->display();
}
public function login(){
$this->display();
}
public function checklogin(){
$username = $_POST[&#39;username&#39;];
$passwd = $_POST[&#39;passwd&#39;];
$user = D("user");
//$User->where(&#39;id=8&#39;)->find();這里的where 語句要注意一下，如果是其他字段的話后面一定要有單引號
$userinfo = $user->where("username =&#39;$username&#39;")->find();
if(!empty($userinfo)){
if($userinfo[&#39;passwd&#39;] == $passwd){
Cookie::set(&#39;userid&#39;,$userinfo[&#39;id&#39;],time()+3600*24);
Cookie::set(&#39;username&#39;,$username,time()+3600*24);
Cookie::set(&#39;lastlogintime&#39;,time(),time()+3600*24);
$this->assign("jumpUrl","__APP__/index/index");
$this->success(&#39;登陸成功！&#39;);
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error(&#39;密碼出錯，請重新輸入！&#39;);
}
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error(&#39;用戶名不存在！&#39;);
}
}
public function loginout(){
Cookie::delete(&#39;username&#39;);
Cookie::delete(&#39;lastlogintime&#39;);
$this->assign("jumpUrl","__APP__/index/index");
$this->success(&#39;您已經(jīng)成功退出，歡迎您的下次登錄！&#39;);
}
}

IndexAction.class.php page:

<?php
// 本類由系統(tǒng)自動生成，僅供測試用途

$this->assign("jumpUrl","__URL__/index");
$this->error($content->getError());//如果創(chuàng)建失敗，表示驗證沒有通過，輸出錯誤信息
}else{//驗證通過，進行其他操作
$content->userid=Cookie::get(&#39;userid&#39;);
$content->add();
$this->assign("jumpUrl","__URL__/index");
$this->success(&#39;添加成功！&#39;);
}
} 
// 數(shù)據(jù)查詢操作  
public function index() {
$content = new ContentModel();
$list = $content->findAll();  
//用戶的cookie
$username = Cookie::get(&#39;username&#39;);
$lastlogintime = Cookie::get(&#39;lastlogintime&#39;);
$this->assign(&#39;list&#39;,$list);    
$this->assign(&#39;title&#39;,&#39;我的首頁&#39;);
$this->assign(&#39;username&#39;,$username);
$this->assign(&#39;lastlogintime&#39;,$lastlogintime);
$this->display();  
} 
// 刪除操作
public function delete(){
$content = new ContentModel();
$id = $_GET[&#39;id&#39;];
if($content->where("id=$id")->delete()){
$this->assign("jumpUrl","__URL__/index");
$this->success(&#39;刪除成功！&#39;);
}else{
$this->assign("jumpUrl","__URL__/index");
$this->error(&#39;刪除失??！&#39;);
}
} 
// 編輯操作
public function edit(){
$content = new ContentModel();
$id = $_GET[&#39;id&#39;];
if($id != &#39;&#39;)
{
//$data = $content->select($id);
$data = $content->where("id=$id")->select();
if(!empty($data)){
$this->assign(&#39;data&#39;,$data);
}else{
echo "數(shù)據(jù)為空！";
}
}
$this->assign(&#39;title&#39;,&#39;編輯頁面&#39;);
$this->display();
}
// 更新操作
public function update(){
$content = new ContentModel();
//直接使用create(),自動會幫你進行數(shù)據(jù)的傳值
/*$content->create();
$content->save(); // 根據(jù)條件保存修改的數(shù)據(jù)
echo "更新數(shù)據(jù)成功！";*/
// 使用post 傳值過來，進行更新
$id = $_POST[&#39;id&#39;];
if($id != &#39;&#39;)
{
$data[&#39;id&#39;] = $id;
$data[&#39;title&#39;] = $_POST[&#39;title&#39;];
$data[&#39;content&#39;] = $_POST[&#39;content&#39;];
if($content->save($data))// 根據(jù)條件保存修改的數(shù)據(jù)
{
$this->assign("jumpUrl","__URL__/index");
$this->success(&#39;更新數(shù)據(jù)成功！&#39;);
}
else{
$this->assign("jumpUrl","__URL__/index");
$this->success(&#39;更新數(shù)據(jù)失?。?amp;#39;);
}
}else
{
echo "保存數(shù)據(jù)失??！";
}
}
}
?>

ContentModel.class.php page:

<?php
class ContentModel extends Model{
/*
* 自動驗證
* array(驗證字段，驗證規(guī)則，錯誤提示，驗證條件，附加規(guī)則，驗證時間)
*/
protected $_validate = array(
array(&#39;title&#39;,&#39;require&#39;,&#39;標題必須填寫!&#39;),
array(&#39;content&#39;,&#39;require&#39;,&#39;內(nèi)容必須填寫!&#39;), 
);
/* 
* 自動填充
* array(填充字段，填充內(nèi)容，填充條件，附加規(guī)則)
*/
protected $_auto = array(
array(&#39;addtime&#39;,&#39;time&#39;,1,&#39;function&#39;),
);
}
?>

UserModel.class.php page:

<?php
class UserModel extends Model{
protected $_validate = array(
array(&#39;username&#39;,&#39;&#39;,&#39;帳號名稱已經(jīng)存在！&#39;,0,&#39;unique&#39;,1), 
);  
}
?>

It should be noted here that using automatic When verifying, you must use $user = D("user") instead of $user = M("user"). Using the M method will report an error. The D function is used to instantiate the Model, and the M function is used to instantiate the user instance. to a file without a model.
