tp Framework of thinkPHP Realizes the Function of Locking Account after Three Login Password Errors

This article describes the example of tp framework (thinkPHP) to achieve three login password error after locking the function of the account. Share it for your reference, as follows:

The tables in the database need to control the number of data name, pwd and number

Whenever you enter the wrong password, the number-1 in the database is locked when it is equal to 0

public function login_do(){
    // Account number 
    $username=$_POST['username'];
    // Password 
    $pwd=$_POST['pwd'];
    $user=M(' Table name ');
    $list=$user->where("username='$username'")->find();
    $time=date("Ymd",time());
    if($list['num']==0){
      if($list['time']!=$time+1){
        $this->error(" Your account has been locked ");
      }
    }
    if($list){
      if($list['pwd']==$pwd){
        $data['id']=$list['id'];
        $data['num']=3;
        $user->save($data);
        $this->success(" Successful login ");
      }else{
        $list['num']=--$list['num'];
        $data['num']=$list['num'];
        $data['id']=$list['id'];
        $data['time']=$time;
        $user->save($data);
        $this->error(" Wrong password, you can also enter ".$list['num']." Times ");
      }
    }else{
      $this->error(" Error account number ");
    }
}
