ThinkPHP user registration login message complete example

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;注册成功！&#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();这里的where 语句要注意一下，如果是其他字段的话后面一定要有单引号
$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;登陆成功！&#39;);
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error(&#39;密码出错，请重新输入！&#39;);
}
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error(&#39;用户名不存在！&#39;);
}
}
public function loginout(){
Cookie::delete(&#39;username&#39;);
Cookie::delete(&#39;lastlogintime&#39;);
$this->assign("jumpUrl","__APP__/index/index");
$this->success(&#39;您已经成功退出，欢迎您的下次登录！&#39;);
}
}

IndexAction.class.php page:

<?php
// 本类由系统自动生成，仅供测试用途
class IndexAction extends Action{
public function insert() {   
$content = new ContentModel();
$result = $content->create();
if(!$result){
$this->assign("jumpUrl","__URL__/index");
$this->error($content->getError());//如果创建失败，表示验证没有通过，输出错误信息
}else{//验证通过，进行其他操作
$content->userid=Cookie::get(&#39;userid&#39;);
$content->add();
$this->assign("jumpUrl","__URL__/index");
$this->success(&#39;添加成功！&#39;);
}
} 
// 数据查询操作  
public function index() {
$content = new ContentModel();
$list = $content->findAll();  
//用户的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;我的首页&#39;);
$this->assign(&#39;username&#39;,$username);
$this->assign(&#39;lastlogintime&#39;,$lastlogintime);
$this->display();  
} 
// 删除操作
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;删除成功！&#39;);
}else{
$this->assign("jumpUrl","__URL__/index");
$this->error(&#39;删除失败！&#39;);
}
} 
// 编辑操作
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 "数据为空！";
}
}
$this->assign(&#39;title&#39;,&#39;编辑页面&#39;);
$this->display();
}
// 更新操作
public function update(){
$content = new ContentModel();
//直接使用create(),自动会帮你进行数据的传值
/*$content->create();
$content->save(); // 根据条件保存修改的数据
echo "更新数据成功！";*/
// 使用post 传值过来，进行更新
$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))// 根据条件保存修改的数据
{
$this->assign("jumpUrl","__URL__/index");
$this->success(&#39;更新数据成功！&#39;);
}
else{
$this->assign("jumpUrl","__URL__/index");
$this->success(&#39;更新数据失败！&#39;);
}
}else
{
echo "保存数据失败！";
}
}
}
?>

ContentModel.class.php page:

<?php
class ContentModel extends Model{
/*
* 自动验证
* array(验证字段，验证规则，错误提示，验证条件，附加规则，验证时间)
*/
protected $_validate = array(
array(&#39;title&#39;,&#39;require&#39;,&#39;标题必须填写!&#39;),
array(&#39;content&#39;,&#39;require&#39;,&#39;内容必须填写!&#39;), 
);
/* 
* 自动填充
* array(填充字段，填充内容，填充条件，附加规则)
*/
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;帐号名称已经存在！&#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.
