i. Start with HelloWorld.

Basic information

If you want to develop typecho, you must have read the source code of the official sample plug-in HelloWorld?

Let's look at the first few lines of the usr/plugins/HelloWorld/Plugin.php file first.

The copy code is as follows:

If (! defined ('_ _ TYPECHO_ROOT_DIR__')) exit

/ * *

* Hello World

*

* @ package HelloWorld

* @ author qining

* @ version 1.0.0

* @ link http://typecho.org

, /

...

...

These lines of code are the basic information of a plug-in, from which we can derive the following basic information related to the plug-in.

Plug-in description-> Hello World

Plug-in package name-> HelloWorld

Plug-in author-> qining

Plug-in version-> 1.0.0

Plug-in links-> http://typecho.org

At the same time, this information is displayed on the plug-in page, as shown in the following figure

Plug-in structure

Let's continue to look at the following code, and the simplest plug-in structure is as follows (to shorten the length, Lao Gao removes the implementation of the specific method)

Each method is basically annotated, and Lao Gao won't repeat it any more.

Doesn't it look easy? In fact, there are still a lot of holes in it.

The copy code is as follows:

Class HelloWorld_Plugin implements Typecho_Plugin_Interface

{

/ * *

* activate the plug-in method. If the activation fails, throw an exception directly.

*

* @ access public

* @ return void

* @ throws Typecho_Plugin_Exception

, /

Public static function activate () {}

/ * *

* disable the plug-in method. If it fails, throw an exception directly.

*

* @ static

* @ access public

* @ return void

* @ throws Typecho_Plugin_Exception

, /

Public static function deactivate () {}

/ * *

* get the plug-in configuration panel

*

* @ access public

* @ param Typecho_Widget_Helper_Form $form configuration panel

* @ return void

, /

Public static function config (Typecho_Widget_Helper_Form $form) {}

/ * *

* configuration panel for individual users

*

* @ access public

* @ param Typecho_Widget_Helper_Form $form

* @ return void

, /

Public static function personalConfig (Typecho_Widget_Helper_Form $form) {}

/ * *

* plug-in implementation method

*

* @ access public

* @ return void

, /

Public static function render () {}

}

Plug-in process

The basic process of the plug-in is like this.

1. When our plug-in is written, it will appear in the background.

two。 When the enable button is clicked, the activate method of the corresponding plug-in class is executed

3. The plug-in is associated with the target plug-in point, waiting for the trigger

4. Call the deactivate method when you click to deactivate
