thinkphp Framework Study Notes (1)

Tp use the holiday to learn about simple framework.

Entry file

tp5 file comes inlet, located in public / index.php, the file content comprises

? < PHP 

// [Application inlet File] 

// Define application catalog 
DEFINE ( 'APP_PATH', __DIR__ '/../application/'. );
 // Load the file frame guide 
the require . __DIR__ '/../thinkphp/start .php ' ;
 ?>

This action is to define a code entry address, e.g. localhost / tp5 / public

Controller

Each module has its own controller, the controller is located, for example, application index file Index.php

In the code, we can make the following changes

<?php

namespace app\index\controller;

class Index
{
    public function index($name = 'World')
    {
        return 'Hello,' . $name . '！';
    }

For example, when accessing url localhost.tp5.com?name = ....

Parameters Parameter name is entered controllable

When a controller which functions to access any subfolders are required to enter one of the controllers

URL and routing

url to access unified entrance url/index.php/模块/控制器/操作

For example, we enter www.tp5.com first to enter the URL that is www.tp5.com/index.php

I.e., if desired to control the entry address of the access controller needs the inserted index.php

<?php
namespace app\index\controller;

class Index
{
    public function index()
    {
        return 'index';
    }
    public function hello($name='')
    {
        return 'love,' .$name. '!';
    }
}

Input url / index.php / index / index / hello / name / hsy in the url

Output: love hsy

So if you want to access the index under subprogram module first you need to enter the controller belongs.

.htaccess

This configuration file is mainly used to rewrite the root directory, when a user visits the site, this configuration file can be substituted into the user needs to jump page.

Define the route

When you define a file location as above rules, you need to enter his controller, entering the specified file.

If a function is very complex site, the file contains a controller in each will be more, so the definition of the route which can simplify the process.

return [
     // add routing rule to index method of operating a controller hello 
    'hello /: name' => 'index / index / hello', 
];

The routing rules represent all hellothe beginning and access parameters are routed to indexthe controller of the hellooperation method.

Earlier url address to access index.php / index / index / hello / name / world

You can now directly reduced to index.php / hello / world

Route parameters:return [ // 定义路由的请求类型和后缀 'hello/[:name]' => ['index/hello', ['method' => 'get', 'ext' => 'html']], ];

Here limiting the request method to get and only ending with .html files.

Routing variables

<?php
namespace app\index\controller;

class Blog
{
    public function get($id)
    {
        return 'cheak id='.$id;
    }
    public function read($name)
    {
        return 'check name='.$name;
    }
    public function archieve($year,$month)
    {
        return 'check'.$year.'/' .$month;
    }
}

Add find items within a controller

Add the application in the following route.php

return [
    'blog/:year/:month' => ['blog/archive', ['method' => 'get'], ['year' => '\d{4}', 'month' => '\d{2}']],
    'blog/:id'          => ['blog/get', ['method' => 'get'], ['id' => '\d+']],
    'blog/:name'        => ['blog/read', ['method' => 'get'], ['name' => '\w+']],
];

Visit url / blog / 5 Finding id = 5
