Complete example of ThinkPHP user registration, login and message, thinkphp user registration

This article uses examples to describe the functions implemented by ThinkPHP, including user registration, login, and leaving messages. What needs to be noted here is that Use the D method when instantiating a user class when there is a user model. Implement .

UserActivion.class.php page:

<&#63;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('注册成功！');
}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();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 = $user->where("username ='$username'")->find();
if(!empty($userinfo)){
if($userinfo['passwd'] == $passwd){
Cookie::set('userid',$userinfo['id'],time()+3600*24);

What needs to be noted here is that when using automatic verification, you must use $user = D("user") instead of $user = M("user") when instantiating. Using the M method will report an error. The D function is used Instantiate Model, the M function user instantiates a file without a model.

Problem with php user registration and login leaving messages!!

It depends on what you want. PHP is a language that can be integrated with scripts. You can write PHP code on the registration page you have made. Of course, in that case, your file will be saved as a PHP file
But in your example, since the registration page has been prepared in DW, we only need to select the ACTION attribute of the FORM form and put the location of your PHP file in it, such as

In this way, the content of your message board will be submitted to the 1.php page and your page format is HTML. We can use the POST method to obtain the content submitted by your form in the 1.PHP page. Of course, you must first Name the name of the submitted variable. For example, we write a text box

The name attribute here is the name of the variable we get
We use $ _POST['text'] to get the content you submitted is that simple

ThinkPHP user registration problem

If it is empty, you should only submit the data in the form.
The main thing you need to do now is to locate the error: Do the keys of the form data correspond to the keys of the database table? Also, has ThinkPHP's token check been turned on?
