Typecho plug-in writing tutorial (3): Saving configuration

This article mainly introduces the typecho plug-in writing tutorial (3): Saving configuration. This article explains the improvement method and how to save it. For configuration and usage issues that need attention, friends in need can refer to it

We made a bare plug-in in the previous section, now let’s start making our plug-in work!

I. Improve the method

Two methods

We implement the activate and deactivate methods

The code is as follows:

public static function activate(){

return 'activate';

　}

public static function deactivate(){

return 'deactivated';

　}

As shown in the above code, we have return values ​​in the activation and uninstallation plug-in methods, so there will be corresponding prompts during the corresponding operations.

Improve the information and make it more down-to-earth

The code is as follows:

public static function activate(){

// do something

Return 'The plug-in is installed successfully, please enter the settings to fill in the access key';

　}

public static function deactivate(){

// do something

return 'Plug-in uninstalled successfully';

　}

　II. How to save configuration

Where is the access key stored? Of course it is the database.

Typecho has implemented the Typecho_Widget_Helper_Form class for us. We only need a little code to get rid of the trouble of writing the form ourselves.

The picture below shows the inheritance relationship of the form class. We can use many types of forms to save our options.

Next we save the interface call address in the config method, similar to the following link (you can find it in the link submission of Baidu Webmaster Platform)

Interface calling address: http://data.zz.baidu.com/urls?site=www.phpgao.com&token=5wK0QtGCzdRzufvW

The code is as follows:

Public static function config(Typecho_Widget_Helper_Form $form){

//Save the interface calling address

$element = new Typecho_Widget_Helper_Form_Element_Text('api', null, null, _t('Interface call address'), 'Please log in to Baidu Webmaster Platform to obtain');

　$form->addInput($element);

　}

There are 5 initialization parameters. What do they do?

The following is the construction method of the form base class. Their functions are form input name, selection item, form default value, form title, and form description.

The code is as follows:

　# var/Typecho/Widget/Helper/Form/Element.php:111

　/**

　* Constructor

*

* @access public

* @param string $name form input name

* @param array $options options

* @param mixed $value form default value

* @param string $label form title

* @param string $description Form description

* @return void

*/

Public function __construct($name = NULL, array $options = NULL, $value = NULL, $label = NULL, $description = NULL)

　# The following is omitted

　III. Issues needing attention during use

After modifying the form name ($name), you need to restart the plug-in to work, because after the plug-in is enabled, the form content is persisted to the database. Only by disabling the plug-in can the plug-in's form settings be cleared

Typecho_Widget_Helper_Form_Element_Fake Ignore

We learned a lot of advanced usage of forms from var/Widget/Plugins/Edit.php, which I will mention at the appropriate time in the future
