Complete example of ThinkPHP user registration login message

In this paper, the functions of ThinkPHP, including user registration, login and message, are described in the form of examples. It is important for everyone to note that D method is used when instantiating a user class in the presence of a user model.

UserActiion. 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(' Successful registration! ');
}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['username'];
$passwd = $_POST['passwd'];
$user = D("user");
//$User->where('id=8')->find(); Here's where  Statement should pay attention to 1 Below, after if it is another field 1 Always have single quotation marks 
$userinfo = $user->where("username ='$username'")->find();
if(!empty($userinfo)){
if($userinfo['passwd'] == $passwd){
Cookie::set('userid',$userinfo['id'],time()+3600*24);
Cookie::set('username',$username,time()+3600*24);
Cookie::set('lastlogintime',time(),time()+3600*24);
$this->assign("jumpUrl","__APP__/index/index");
$this->success(' Login succeeded! ');
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error(' Password error, please re-enter! ');
}
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error(' User name does not exist! ');
}
}
public function loginout(){
Cookie::delete('username');
Cookie::delete('lastlogintime');
$this->assign("jumpUrl","__APP__/index/index");
$this->success(' You have successfully exited, welcome to log in next time! ');
}
}
 

IndexAction. class. php page:

<?php
//  This class is automatically generated by the system and is for testing purposes only 
class IndexAction extends Action{
public function insert() {   
$content = new ContentModel();
$result = $content->create();
if(!$result){
$this->assign("jumpUrl","__URL__/index");
$this->error($content->getError());// If the creation fails, it means that the verification failed and an error message is output 
}else{// Verify passed and perform other operations 
$content->userid=Cookie::get('userid');
$content->add();
$this->assign("jumpUrl","__URL__/index");
$this->success(' Add successfully! ');
}
} 
//  Data query operation   
public function index() {
$content = new ContentModel();
$list = $content->findAll();  
// User's cookie
$username = Cookie::get('username');
$lastlogintime = Cookie::get('lastlogintime');
$this->assign('list',$list);    
$this->assign('title',' My Home Page ');
$this->assign('username',$username);
$this->assign('lastlogintime',$lastlogintime);
$this->display();  
} 
//  Delete operation 
public function delete(){
$content = new ContentModel();
$id = $_GET['id'];
if($content->where("id=$id")->delete()){
$this->assign("jumpUrl","__URL__/index");
$this->success(' Delete successful! ');
}else{
$this->assign("jumpUrl","__URL__/index");
$this->error(' Delete failed! ');
}
} 
//  Edit operation 
public function edit(){
$content = new ContentModel();
$id = $_GET['id'];
if($id != '')
{
//$data = $content->select($id);
$data = $content->where("id=$id")->select();
if(!empty($data)){
$this->assign('data',$data);
}else{
echo " Data is empty! ";
}
}
$this->assign('title',' Edit page ');
$this->display();
}
//  Update operation 
public function update(){
$content = new ContentModel();
// Direct use create(), Automatically will help you to transfer the data value 
/*$content->create();
$content->save(); //  Save modified data according to conditions 
echo " Update data successfully! ";*/
//  Use post  Pass the value over and update it 
$id = $_POST['id'];
if($id != '')
{
$data['id'] = $id;
$data['title'] = $_POST['title'];
$data['content'] = $_POST['content'];
if($content->save($data))//  Save modified data according to conditions 
{
$this->assign("jumpUrl","__URL__/index");
$this->success(' Update data successfully! ');
}
else{
$this->assign("jumpUrl","__URL__/index");
$this->success(' Failed to update data! ');
}
}else
{
echo " Failed to save data! ";
}
}
}
?>
 

ContentModel. class. php page:

<?php
class ContentModel extends Model{
/*
*  Automatic validation 
* array( Validation Fields, Validation Rules, Error Prompts, Validation Criteria, Attached Rules, Validation Time )
*/ 
protected $_validate = array(
array('title','require',' Title must be filled in !'),
array('content','require',' Contents must be filled in !'), 
);
/* 
*  Autofill 
* array( Fill Fields, Fill Contents, Fill Criteria, Attach Rules )
*/
protected $_auto = array(
array('addtime','time',1,'function'),
);
}
?>

UserModel. class. php page:

<?php
class UserModel extends Model{
protected $_validate = array(
array('username','',' Account name already exists! ',0,'unique',1), 
);  
}
?>

It should be noted here that when using automatic verification, we should use $user = D ("user") instead of $user = M ("user"). If we use M, we will report an error. The D function is used to instantiate Model, and the M function user instantiates a file without a model.
