Recently, Lao Gao is writing a plug-in about typecho. because typecho is not like wordpress, there are so many reference documents, there are still many pitfalls in writing a plug-in, but with the continuous development of research, the old master is also getting started, so I will summarize this article and share it with you!

I. starting from HelloWorld

Basic information

Certainly, if you want to develop typecho, you must have read the official example plug-in HelloWorld source code?

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

The 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. we can obtain the following basic information about 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 link ---> http://typecho.org

All the information is displayed on the plug-in page, as shown in figure

Plug-in structure

Let's continue to look back at the code. the simplest plug-in structure is as follows (to shorten the length, Laogu removed the implementation of specific methods)

Every method has annotations, so I will not repeat them here.

It looks simple, right? In fact, there are still many pitfalls.

The code is as follows:

Class HelloWorld_Plugin implements Typecho_Plugin_Interface

{

/**

* Activate the plug-in method. If activation fails, an exception is thrown directly.

*

* @ Access public

* @ Return void

* @ Throws Typecho_Plugin_Exception

*/

Public static function activate (){}

/**

* Disable the plug-in method. if it fails to be disabled, an exception is thrown.

*

* @ Static

* @ Access public

* @ Return void

* @ Throws Typecho_Plugin_Exception

*/

Public static function deactivate (){}

/**

* Obtain 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 ){}

/**

* Personal user configuration panel

*

* @ Access public

* @ Param Typecho_Widget_Helper_Form $ form

* @ Return void

*/

Public static function personalConfig (Typecho_Widget_Helper_Form $ form ){}

/**

* Plugin implementation method

*

* @ Access public

* @ Return void

*/

Public static function render (){}

}

Plug-in process

The basic process of the plug-in is as follows.

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

2. click the Enable button to execute the activate method of the corresponding plug-in class.

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

4. call the deactivate method when you click disable.

This section is complete.

In the next section, I will describe the plug-in class methods in more detail.
