How to create a new shipping method in WooCommerce..?

Today, we will learn how to create a new shipping method in WooCommerce.

For this, we will create a separate plugin and go through step by step.

First of all, Create a function file where all basic details are added like plugin name description author, etc.

Create function.php

<?php
/**
 * Plugin Name:Webkul WooCommerce Shipping
 * Plugin URI: https://webkul.com
 * Description:This is the test shipping from webkul
 * Author: Webkul
 * Author URI: https://webkul.com
 * Version: 1.0.0
 * Text Domain: wkwc-shipping
 * Domain Path: languages/
 *
 * @package Webkul WooCommerce Shipping
 */

/*----- Preventing Direct Access -----*/
defined( 'ABSPATH' ) || exit;

/**
 * Include your shipping file.
 */
function wkwc_include_shipping_method() {
  require_once 'wkwc-class-shipping-method.php';
}
add_action( 'woocommerce_shipping_init', 'wkwc_include_shipping_method' );

/**
 * Add Your shipping method class in the shipping list
 */
function wkwc_add_shipping_method( $methods ) {
  $methods[] = 'WKWC_Webkul_Shipping_Method';
  return $methods;
}
add_filter( 'woocommerce_shipping_methods', 'wkwc_add_shipping_method' );

Action woocommerce_shipping_init – It will be used to include your shipping class file path

Filter woocommerce_shipping_methods – It will be used to add a shipping class in the WooCommerce shipping class list.

Now it will be listed in the plugin list.

WooCommerce provides the WC_Shipping_Method class to use and create your own custom shipping method so we just extend here the same class to override the calculate_shipping method and other methods to create the new shipping.

Now create the class file wkwc-class-shipping-method.php

<?php

defined( 'ABSPATH' ) || exit;

class WKWC_Webkul_Shipping_Method extends WC_Shipping_Method {

  /**
   * Shipping class
   */
  public function __construct() {

    // These title description are display on the configuration page
    $this->id = 'wkwc-shipping-method';
    $this->method_title = esc_html__('Webkul Shipping', 'wkwc-shipping' );
    $this->method_description = esc_html__('Webkul WooCommerce Shipping', 'wkwc-shipping' );

    // Run the initial method
    $this->init();

   }

   /**
    ** Load the settings API
    */
   public function init() {
     // Load the settings API
     $this->init_settings();

     // Add the form fields
     $this->init_form_fields();
   }

   public function init_form_fields() {

     $form_fields = array(

       'enabled' => array(
          'title'   => esc_html__('Enable/Disable', 'wkwc-shipping' ),
          'type'    => 'checkbox',
          'label'   => esc_html__('Enable this shipping method', 'wkwc-shipping'  ),
          'default' => 'no'
       ),

       'title' => array(
          'title'       => esc_html__('Method Title', 'wkwc-shipping' ),
          'type'        => 'text',
          'description' => esc_html__('Enter the method title', 'wkwc-shipping'  ),
          'default'     => esc_html__('', 'wkwc-shipping' ),
          'desc_tip'    => true,
       ),

       'description' => array(
          'title'       => esc_html__('Description', 'wkwc-shipping' ),
          'type'        => 'textarea',
          'description' => esc_html__('Enter the Description', 'wkwc-shipping'  ),
          'default'     => esc_html__('', 'wkwc-shipping' ),
          'desc_tip'    => true
       ),

       'cost' => array(
          'title'       => esc_html__('Cost', 'wkwc-shipping' ),
          'type'        => 'number',
          'description' => esc_html__('Add the method cost', 'wkwc-shipping'  ),
          'default'     => esc_html__('', 'wkwc-shipping' ),
          'desc_tip'    => true
       )
     );

      $this->form_fields = $form_fields;
   }

   /**
    ** Calculate Shipping rate
    */
   public function calculate_shipping( $package = array() ) {
      $this->add_rate( array(
        'id'     => $this->id,
        'label'  => $this->settings['title'],
        'cost'   => $this->settings['cost']
      ));
   }

}

After activating the plugin we can see that Webkul Shipping is listed under the WooCommerce Shipping list.
