How to add Custom Description field in Shipping methods (Backend)

问题

I want to add a custom field in Shipping Zone page under shipping method, it will be a text input, the user will able to add a custom message and I'll show that message in the front end.

I noticed it saves the data in wp_woocommerce_shipping_zone_methods table which doesn't have any extra column to save the data; so I think I have to use my custom logic, but I don't know the name of the hook(s).

So my question is, is there is any hook which will help/allow me

To add a custom field.
To add a custom column.

TL;DR:

回答1:

this is how I implemented the custom description field in shipping methods with flat rate and free shipping

My function.php file:

add_filter( 'woocommerce_shipping_instance_form_fields_flat_rate', array( $this, 'add_extra_fields_in_flat_rate' ), 10, 1);
public function add_extra_fields_in_flat_rate($settings)
    {
        $counter = 0;
        $arr = array();
        foreach ($settings as $key => $value) <br>
        {
            if($key=='cost' && $counter==0)
            {
                $arr[$key] = $value; 
                $arr['shipping_extra_field'] = array(
                    'title'         => __( 'Shipping Extra Field', 'woocommerce' ), 
                    'type'             => 'text', 
                    'placeholder'    => 'shipping',
                    'description'    => ''
                ); 
                $counter++; 
            } 
            else 
            {
                $arr[$key] = $value;
            } 
        }
        return $arr; 
    }

回答2:

add_action('woocommerce_init', 'shipping_instance_form_fields_filters');

function shipping_instance_form_fields_filters()
{
    $shipping_methods = WC()->shipping->get_shipping_methods();
    foreach($shipping_methods as $shipping_method) {
        add_filter('woocommerce_shipping_instance_form_fields_' . $shipping_method->id, 'shipping_instance_form_add_extra_fields');
    }
}

function shipping_instance_form_add_extra_fields($settings)
{
    $settings['shipping_extra_field'] = [
        'title' => 'Shipping extra field',
        'type' => 'text', 
        'placeholder' => 'shipping',
        'description' => ''
    ];

    return $settings;
}

Thanks @Wprog_dy for idea, but your code only adds field to the 'flat_rate' shipping method and your function is really weirdly complicated.

My example will add a custom field to all shipping methods

Late in time but you may use:

add_action('woocommerce_product_options_general_product_data', 'my_custom_fields');

function my_custom_fields() {
    $field = array(
       //This ID will be use on the _postmeta table as key_name
       'id' => 'my_custom_message',
       //Text that goes inside the label tag
       'label' => 'Message:',
       //This text will appear on the description column
       'description' => 'This is a custom message not part of WooCommerce',
       //Boolean that determines the display of the description
       'desc_tip' => true,
       //Standard html input placeholder
       'placeholder' => 'Type a message',
    );
    woocommerce_wp_text_input($field);
}

add_action('woocommerce_process_product_meta', 'save_my_custom_fields');

function save_my_custom_fields($post_id) {
    update_post_meta(
        $post_id,
        'my_custom_message',
        esc_attr($POST['my_custom_message'])
    );
}

$field array in my opinion must have at minimum:

$field = array(
    'id' => 'my_custom_message',//This ID will be use on the _postmeta table as key_name
    'label' => 'Message:',//Text that goes inside the label tag
    'description' => 'This is a custom message not part of WooCommerce',//This text will appear on the description column
    'desc_tip' => true,//Boolean that determines the display of the description
    'placeholder' => 'Type a message',//Standard html input placeholder
);

You may also specify the following:

    'class' => 'css-class',//Class attributte for the input tag
    'style' => 'background:red',//Style attribute for the input tag
    'wrapper_class' => 'css-class',//Class for the wrapper of the input tag, it is a paragraph
