A WordPress plugin is a module that handles a specific function by using APIs provided by WordPress to interfere with the core source code. To create a plugin, you need to go to the plugins folder in your theme and follow the steps outlined in the article. This includes creating a folder, a file, adding functions, and customizing CSS. Shortcodes can be used to display the latest posts in WordPress. The article provides a tutorial on creating plugins in WordPress with easy-to-follow instructions.

Creating a WordPress Plugin
WordPress plugins are modules that handle a certain function. Plugins will use APIs provided by WordPress to interfere with the core instead of editing directly in the core.
The plugin will use Action Hook and Filter Hook to intervene in the Core of the source code. If you do not understand these concepts clearly, you can read them again at this lesson.
To write a WordPress plugin, you first need to go to the plugins folder in your Theme. If using XAMPP on localhost, access the path: C:\xampp\htdocs\your-theme\wp-content\plugins.
Step 1: Create a new folder called Kiểm TRA or you can name it whatever you want.
Step 2: Create a file test.php with the following content:
/**
* Plugin Name: Plugin này tên là Test
* Plugin URI: https://wikiminhduy.vn/
* Description: Đây là plugin dùng để Test
* Version: 1.0
* Author: Wiki Minh Duy
* Author URI: https://wikiminhduy.vn/
**/Step 3: Go to Plugin -> Installed Plugins activate the plugin -> Press Active to enable it.
By now, you have a plugin, though it has no functionality yet as we haven’t added any code snippets into it.
Step 4: Write functionality for the plugin. Add a function to test.php:
function wikiminhduy_copyright( $content ) {
$content="Copyright by Wiki Minh Duy";
return $content;
}
add_shortcode( 'change_copyright', 'wikiminhduy_copyright' );Add CSS to style the plugin:
function css_styles() {
wp_register_style('css_styles', plugins_url('doctype_styles_new.css', __FILE__));
wp_enqueue_style('css_styles');
}
add_action('wp_enqueue_scripts', 'css_styles');Write a file named doctype_styles_new.css to customize CSS.
Step 5: Go to file footer.php and insert the shortcode where you want it to display:
<?php echo do_shortcode('[change_copyright]'); ?>This is a plugin that uses Shortcode, and also uses Action Hook and Filter Hook. The functional segments in the file are similar to when using the file functions.php.
In this paragraph, I have a tutorial on Shortcode to display the latest post in WordPress for practice. You can use my tutorial to create your plugin to show new posts.
