ThinkPHP5 Development (i) Implement login function ____php

Project code is hosted on Csdn-code:
Https://code.csdn.net/u012995856/tp5pro/tree/master

Mainly from these three aspects: database PHP Code

HTML code &thinkphp View template code

The database uses mysql5.7. and use the latest version of PHP php7,apache2.4,ubuntu16.04

Ready: Download the THINKPHP5 code, put the Apache directory, give 777 permissions

chmod 777-r tp5/

Use Atom or sublime or phpstorm to open your project and prepare coding to build a database thinkphp5

First put the frame, run up, and then strengthen.
2. Write PHP code based on THINKPHP5 's manual on "Looking at the cloud"
Here you can directly use the ThinkPHP5 provided by the script can directly generate code, you can also manually build the directory to build files
Application directory Structure

login.php

<?php
namespace App\index\controller;
Use Think\view;
Use Think\controller;
Use App\index\model\user;
/**
 *
 *
/class Login extends controller{public
  function Index () {
    $view = new View ();
    return $view->fetch (' index ');
  }
  Public Function Login ($user _name= ', $user _passwd= ') {
    $user = user::get ([
        ' user_name ' => $user _name,
        ' userpasswd ' => $user _passwd
        ]);
    if ($user) {
        echo ' login succeeded '. $user _name.md5 ($user _passwd);
    else{return
        $this->error (' Login failed ');}}

user.php

<?php
namespace App\index\model;
Use Think\model;
Class User extends model{
    protected $pk = ' user_id ';//Set Primary key

}

3. View Code HTML
Use native HTML, CSS not using front-segment frame
Effect Chart:

Login/index.html

<! doctype>
 After reading the THINKPHP5 manual, I have not solved the verification code problem. thinkphp Debugging tools can directly see the database password, user-submitted password, although they use the post submission form. After the login needs to do session, write login log, log logon time, IP and other information and some security issues ...
