Preliminary mastery of thinkphp framework

Tag: Name member Thinksns project configuration class start API PHP file structure

In order to help the teacher with Thinksns two times to develop a micro-BO system, specifically spent a few days to learn thinkphp framework, now some thinkphp knowledge to record.

First, declare:

This article is not a complete tutorial, just to summarize the problems encountered in the development, if you need to learn thinkphp framework, please refer to the official website documentation:

Directory structure

Catalog/File	Description
thinkphp.php	Frame Entry File
Common	Framework Common Files Directory
Conf	Framework configuration file Directory
Lang	Framework System Language Directory
Lib	System core base Class Library Directory
Tpl	System Templates Directory
Extend	Framework Extensions directory (for more information on extended directories, refer to the Extensions section later)

My file structure

Entrance (thinkphp.php)

1, first in the Web root directory (I use the phpstudy, is the WWW folder) under the creation of an app project (this app is our project name).

2, will download the thinkphp decompression (I was extracted to the app, named Thinkphp).

3. Create a index.php file under the app directory and add two simple lines of code:

    <?php
Define ("App_debug", TRUE);　　Open debug mode, easy to debug   require '/thinkphp frame directory/thinkphp.php '; Mine is/thinkphp/thinkphp.php.

The purpose of this line of code is to load the thinkphp framework's Portal file thinkphp.php, which is the first step in all thinkphp-based development applications.
Then, access the portal file in the browser.

        http://localhost/app/index.php

Because index.php is the default home page, it can also be omitted.

Template (TPL)

Under the TPL folder is the template page, you can place HTML, PHP and other pages.

Support multiple modules at the same time, you can create multiple folders under the TPL, each folder corresponds to a module, and a module and a controller corresponding (need the same name)

It's mine:

Two modules form, Index

There are two folders under the TPL form, Index

The corresponding controller is also two FormController.class.php, IndexController.class.php

Controllers (Controller)

Name: module name +controller

pathinfo mode : Is the system's default URL mode, provides the best SEO support, the system has done the environment compatible processing, so it can support the majority of host environment.

Corresponding to the URL pattern above, the URL access address under PathInfo mode is:

    http://localhost/app/index.php/module/action/var/value/

Module name (controller name), without controller//action as operation name (method name in controller), parameter name//value without model//var as argument value
var and value appear in pairs

It's mine:

    Http://localhost/app/index.php/Index/index

Call the index () method under Indexcontroller
If the method does not exist, the tpl/index/index.html page is called directly

Models (model)

1, naming: module name +model

In the thinkphp model, there are several attribute definitions for the name of the data table, declared in the corresponding model as attribute fields (or called member variables):

Properties	Description
TableName	A data table name that does not contain a table prefix, typically the default is the same as the model name, which needs to be defined only if your table name differs from the name of the current model class.
Truetablename	The name of the data table that contains the prefix, which is the actual table name in the database, which does not need to be set, only if the above rules do not apply, or in special cases.
DbName	Define the database name that the model currently corresponds to, only if you have a different database name and configuration file for your current model class.

As long as the naming specification, thinkphp will find the database table you want to call according to the model name, of course, if you have to build.

Rules:

1) The table name is Tp_categories (tp_ is the table prefix and is configured in the configuration file)

2) Table name Top_depts,top_ is not a system-configured table prefix, you need to use the full name of the table

3) can set the database

    protected $dbName = ' top ';

Call:

You can call this module model, or it can be called across projects or modules.

This module:

D ("Usermodel")

Cross-project:

D ("Usermodel", "app")//d (model name, project name)

The M method is similar to the D method, but I only use the D method

function library

Available through load (@.hello), hello for function library file name

You can also define Load_ext_file parameters in the project configuration file, for example:

    "Load_ext_file" = "user,db"

Class Library

Import allows you to introduce a class package that can be used across projects or modules

Import ("App.Model.UserModel");

App for application name model indicates model Usermodel

Database

This piece of stuff is too much, use also most frequently, therefore, the official document introduction is very detailed, please click on the link at the beginning of the article to view

Wrote for a long time, hope for everyone a little useful.
