What is a proper way to implement a plugin which creates a multi step buying experience for WooCommerce products?

Creating a multi-step buying experience for WooCommerce products can be done by creating a custom plugin. Here is a general outline of the process:

1. Create a new folder and name it as per your preference. This will be the root folder for your plugin.
2. Create a new PHP file with the same name as the root folder and include the plugin header comments to define the plugin’s name, version, and other details.
3. Use the WooCommerce actions and filters to customize the existing buying process. For example, you can use the ‘woocommerce_before_add_to_cart_button’ action to add a new button or link that will lead to the next step in the buying process.
4. Create new pages for each step of the buying process, using the ‘add_menu_page’ function in WordPress. This function will allow you to create new pages in the WordPress admin area that will be used to display the different steps of the buying process.
5. Use the ‘woocommerce_add_to_cart’ action to handle the data submitted by the customer during the buying process. You can use this action to save the customer’s data to the database, or to send it to an external service for processing.
6. Use JavaScript and CSS to create a custom layout for the new pages and to handle the interactions between the different steps of the buying process.
7. Test your plugin thoroughly to ensure that it works as expected and that it does not conflict with any other plugins or themes.
8. Once your plugin is ready, you can share it with others by submitting it to the WordPress plugin repository or by distributing it through your website.

Here is an example of how the main plugin file could look like:

<?php
/**
* Plugin Name: Multi-Step Buying Experience
* Plugin URI: https://example.com/multistep-buying-experience
* Description: A custom plugin that creates a multi-step buying experience for WooCommerce products
* Version: 1.0
* Author: Your Name
* Author URI: https://example.com
* License: GPL2
*/

add_action( 'woocommerce_before_add_to_cart_button', 'multistep_buying_experience' );
function multistep_buying_experience() {
    echo '<a href="' . get_permalink( get_page_by_path( 'step-1' ) ) . '" class="button">Next Step</a>';
}

add_action( 'init', 'register_multistep_pages' );
function register_multistep_pages() {
    add_menu_page( 'Step 1', 'Step 1', 'manage_options', 'step-1', 'step_1_content', '', 20 );
    add_menu_page( 'Step 2', 'Step 2', 'manage_options', 'step-2', 'step_2_content', '', 21 );
    add_menu_page( 'Step 3', 'Step 3', 'manage_options', 'step-3', 'step_3_content', '', 22 );
}

function step_1_content() {
    //content for step 1
}
