How to Show Shipping Method IDs in WooCommerce? - Tyche Softwares

Code Explanation:

Let’s break down the code step by step:

  1. Class Definition (TS_ShowShippingMethodIDs):
    • This class encapsulates the functionality of the plugin.
    • It has a private static property instance to hold a singleton instance of the class.
    • The get_instance() method is a static method that returns an instance of the class, following the Singleton pattern.
  2. Constructor (__construct()):
    • The constructor initializes the plugin by calling the init() method.
  3. Initialization (init()):
    • This method sets up WordPress actions that hook into specific events.
    • add_action(‘woocommerce_settings_shipping‘, array($this, ‘ts_add_to_shipping_settings’), 20);: This action adds the plugin’s content to the WooCommerce shipping settings page.
    • add_action(‘admin_head’, array($this, ‘ts_add_shipping_method_ids_css’));: This action adds CSS styling for the table to the WordPress admin head section.
  4. Helper Method (ts_is_shipping_zones_page()):
    • This private method checks if the current page is the shipping zone main page in the WooCommerce settings.
  5. CSS Styling (ts_add_shipping_method_ids_css()):
    • This method adds CSS styles to the WordPress admin head section.
    • The styles define the appearance of the table that will display the shipping method IDs.
  6. Table Generation (ts_add_to_shipping_settings()):
    • This method generates the content to be displayed on the WooCommerce shipping settings page.
    • It first checks if the current page is the Shipping Zones main page using the ts_is_shipping_zones_page() method.
    • It then retrieves the shipping zones using WooCommerce’s data store.
    • It loops through each zone and extracts the shipping methods associated with the zone.
    • For each shipping method, it retrieves the method’s title, user-readable title, and rate ID.
    • The information is presented in a table format with zone names and corresponding shipping methods and their IDs.
  7. Instantiation and Execution:
    • The last lines of code create an instance of the Ts_ShowShippingMethodIDs class, which triggers the plugin functionality.

Conclusion:

This code snippet proves useful when you are planning out custom shipping options on your WooCommerce store via code. When using filters and hooks for customizations, these shipping IDs are what you would need.
