Custom WooCommerce Shipping Method - php

Question

I have this working code which generating and saving properly a custom shipping method under woocommerce setting > shipping zones.
My problem is that I can't make the shipping method show on the checkout page.
Any help on how to resolve this issue and maybe extend the code a bit would be greatly appreciated.
add_filter('woocommerce_shipping_methods', 'add_local_shipping');
function add_local_shipping($methods) {
$methods['local_shipping'] = 'Local_Shipping_Method';
return $methods;
}
class Local_Shipping_Method extends WC_Shipping_Method {
public function __construct($instance_id = 0) {
$this->id = 'local_shipping';
$this->instance_id = absint($instance_id);
$this->domain = 'local_shipping';
$this->method_title = __('Pickup', $this->domain);
$this->method_description = __('Pickup Location for WooCommerce', $this->domain);
$this->title = __('Pickup Location', $this->domain);
$this->supports = array(
'shipping-zones',
'instance-settings',
'instance-settings-modal',
);
$this->instance_form_fields = array(
'enabled' => array(
'title' => __( 'Enable/Disable' ),
'type' => 'checkbox',
'label' => __( 'Enable this shipping method' ),
'default' => 'yes',
),
'title' => array(
'title' => __( 'Method Title' ),
'type' => 'text',
'description' => __( 'This controls the title which the user sees during checkout.' ),
'default' => __( 'Pickup Location' ),
'desc_tip' => true
),
'tax_status' => array(
'title' => __( 'Tax status', 'woocommerce' ),
'type' => 'select',
'class' => 'wc-enhanced-select',
'default' => 'taxable',
'options' => array(
'taxable' => __( 'Taxable', 'woocommerce' ),
'none' => _x( 'None', 'Tax status', 'woocommerce' ),
),
),
'cost' => array(
'title' => __( 'Cost', 'woocommerce' ),
'type' => 'text',
'placeholder' => '0',
'description' => __( 'Optional cost for pickup.', 'woocommerce' ),
'default' => '',
'desc_tip' => true,
),
);
$this->enabled = $this->get_option( 'enabled' );
$this->title = __('Pickup Location', $this->domain);
add_action('woocommerce_update_options_shipping_' . $this->id, array($this, 'process_admin_options'));
}
public function calculate_shipping( $package = array() ) {
$this->add_rate( array(
'id' => $this->id . $this->instance_id,
'label' => $this->title,
'cost' => 0,
) );
}
}

The way you have tried it is wrong. And it's not recommended to keep the text domain in a variable or a method.
To Create a Custom Shipping Method You have to follow these steps I have corrected on your code.
Hope this helps. You can learn more about how to create new shipping method here. Feel free
// To initialize your new shipping method you have to keep it in function
function local_shipping_init() {
if ( ! class_exists( Local_Shipping_Method ) ) {
class Local_Shipping_Method extends WC_Shipping_Method {
public function __construct( $instance_id = 0 ) {
$this->id = 'local_shipping';
$this->instance_id = absint( $instance_id );
$this->method_title = __( 'Pickup', 'text-domain' );
$this->method_description = __( 'Pickup Location for WooCommerce', 'text-domain' );
$this->title = __( 'Pickup Location', 'text-domain' );
$this->supports = array(
'shipping-zones',
'instance-settings',
'instance-settings-modal',
);
// then you have to call this method to initiate your settings
$this->init();
}
public function init() {
// this method used to initiate your fields on settings
$this->init_form_fields();
// this is settings instance where you can declar your settings field
$this->init_instance_settings();
// user defined values goes here, not in construct
$this->enabled = $this->get_option( 'enabled' );
$this->title = __( 'Pickup Location', 'text-domain' );
// call this action in init() method to save your settings at the backend
add_action( 'woocommerce_update_options_shipping_' . $this->id, array( $this, 'process_admin_options' ) );
}
public function init_instance_settings() {
// you have to keep all the instance settings field inside the init_instance_settings method
$this->instance_form_fields = array(
'enabled' => array(
'title' => __( 'Enable/Disable' ),
'type' => 'checkbox',
'label' => __( 'Enable this shipping method' ),
'default' => 'yes',
),
'title' => array(
'title' => __( 'Method Title' ),
'type' => 'text',
'description' => __( 'This controls the title which the user sees during checkout.' ),
'default' => __( 'Pickup Location' ),
'desc_tip' => true
),
'tax_status' => array(
'title' => __( 'Tax status', 'woocommerce' ),
'type' => 'select',
'class' => 'wc-enhanced-select',
'default' => 'taxable',
'options' => array(
'taxable' => __( 'Taxable', 'woocommerce' ),
'none' => _x( 'None', 'Tax status', 'woocommerce' ),
),
),
'cost' => array(
'title' => __( 'Cost', 'woocommerce' ),
'type' => 'text',
'placeholder' => '0',
'description' => __( 'Optional cost for pickup.', 'woocommerce' ),
'default' => '',
'desc_tip' => true,
),
);
}
public function calculate_shipping( $package = array() ) {
$this->add_rate( array(
'id' => $this->id, // you should define only your shipping method id here
'label' => $this->title,
'cost' => 0,
) );
}
}
}
}
add_action( 'woocommerce_shipping_init', 'local_shipping_init' ); // use this hook to initialize your new custom method
function add_local_shipping( $methods ) {
$methods['local_shipping'] = 'Local_Shipping_Method';
return $methods;
}
add_filter( 'woocommerce_shipping_methods', 'add_local_shipping' );
The code is tested and works fine. See the screenshot below.
