ThinkPHP5 Development (i) Implementation of login function detailed

Mainly from these three aspects to start:

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

Get ready:

• Download THINKPHP5 code, put into Apache directory, give 777 permissions

chmod 777-r tp5/

• Use Atom or sublime or phpstorm to open your project and prepare for the coding

1. Build Database Thinkphp5

--phpMyAdmin SQL dump--version 4.4.15.5--http://www.phpmyadmin.net----host:localhost--Generation time:2016-07-06 20 : 42:33--Server version: 5.7.12-log--PHP version:7.0.7set sql_mode = "No_auto_value_on_zero"; Set time_zone = "+00:00";/*!40101 set @OLD_CHARACTER_SET_CLIENT =@ @CHARACTER_SET_CLIENT */;/*!40101 set @OLD_CHARACTER_ set_results=@ @CHARACTER_SET_RESULTS */;/*!40101 SET @OLD_COLLATION_CONNECTION =@ @COLLATION_CONNECTION */;/*!40101 SET NAMES UTF8MB4 */;----Database: The structure of the table ' THINKPHP5 '----------------------------------------------------------------  ' Think_user '--create TABLE IF not EXISTS ' think_user ' (' user_id ' int (one) not null, ' user_name ' varchar (255) is not NULL, ' Usersex ' int (one) default null, ' Usertel ' varchar (255) default NULL, ' useremail ' varchar (255) default NULL, ' Useraddres s ' varchar (255) default NULL, ' Userbirth ' varchar (255) default NULL, ' userjointime ' varchar (255) default NULL, ' Userpas  SWD ' varchar (255) default NULL, ' usersignature ' varchar (255) default NULL,' Userhobby ' varchar (255) default NULL) Engine=innodb default charset=utf8mb4;----Dump the data in the table ' Think_user '--insert into ' Think_user ' (' user_id ', ' user_name ', ' usersex ', ' Usertel ', ' useremail ', ' useraddress ', ' Userbirth ', ' userjointime ', ' USERPASSWD ', ' usersignature ', ' Userhobby ') VALUES (0, ' thinkphp ', 1, ' 15700000000 ', ' emial@email.com ', ' Shandong province Jinan * * * road ', ' 1111111 ', ' 111111 ', ' QQQ ', null, NULL);----Indexes for dumped tables------Indexes for table ' think_user '--alter table ' t Hink_user ' ADD PRIMARY KEY (' user_id ');/*!40101 set character_set_client= @OLD_CHARACTER_SET_CLIENT */;/*!40101 set character_set_results= @OLD_CHARACTER_SET_RESULTS */;/*!40101 SET collation_connection= @OLD_COLLATION_CONNECTION */ ;

First set up a good frame, run up, and then strengthen.
2. Write PHP code according to THINKPHP5 's manual on "See The Cloud"
Here you can directly use the script provided by THINKPHP5 to generate the code directly, or you can manually build the directory to build the file
Application directory Structure

login.php

<?phpnamespace 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

<?phpnamespace app\index\model;use think\model;class User extends model{    protected $pk = ' user_id ';//Set Primary KEY}

3. View Code HTML
Using native HTML, CSS does not use the front paragraph frame
：

Login/index.html

<! doctype>

 

 
  
 
   
 
 Read ThinkPHP5 's manual and haven't solved the captcha problem yourself. The 
 
 
   
 
 thinkphp debugging tool can directly see the database password, user submitted password, although their own use of the post submission form. 
 
 
   
 
 Need to do session after login, write log log, log login time, IP and other information 
 
 
   
 
 There are some security issues ...
