Add different custom labels to Woocommerce shipping methods

Question

In WooCommerce, I am trying to add "shipping estimates" to my shipping methods (all of them are flat rate type), so it looks like this:

Only all the estimated dates are different…

My problem is that I can't seem to target specific instances. I can only select entire method (flat rate), I checked for my methods instance ID's, since those are unique:

But it only works when I put 0 as a case in php switch method. 2,3,4,5,7 do not work.

Here is my code:

function sv_shipping_method_estimate_label($label, $method) {
    $label. = '<br /><small>';
    switch ($method - > instance_id) {
        case 0:
            $label. = 'Est delivery: 2-400 days';
            break;
    }

    $label. = '</small>';
    return $label;
}
add_filter('woocommerce_cart_shipping_method_full_label', 'sv_shipping_method_estimate_label', 10, 2);

The code obviously results in all the same estimates for all my shipping methods.

thanks!

im using this:

case 'flat_rate': $label .= 'Lieferzeit: 2-3 Tage flat'; break; case 'free_shipping': $label .= 'Lieferzeit: 2-3 Tage free'; break; case 'international_delivery': $label .= 'Lieferzeit: 4-5 Tage Inter'; break; default: $label .= 'Lieferzeit: 2-3 Tage default';

the international_delivery is not displaying 'Lieferzeit: 4-5 Tage Inter'. I gues I need to refer to it not as 'international_delivery' but something else. I tried 'flat_rate7' also not working.

I have set 2 shipping Zones 1 for Germany and the other is called Euro and contains the rest of european counties

Here is the correct way to do what you are expecting (you should only need to change the texts to get your correct labels):

add_filter('woocommerce_cart_shipping_method_full_label', 'custom_shipping_method_label', 10, 2);
function custom_shipping_method_label( $label, $method ){
    $rate_id = $method->id; // The Method rate ID (Method Id + ':' + Instance ID)

    // Continue only if it is "flat rate"
    if( $method->method_id !== 'flat_rate' ) return $label;

    switch ( $method->instance_id ) {
        case '3':
            $txt = __('Est delivery: 2-5 days'); // <= Additional text
            break;
        case '4':
            $txt =  __('Est delivery: 1 day'); // <= Additional text
            break;
        case '5':
            $txt =  __('Est delivery: 2-3 days'); // <= Additional text
            break;
         // for case '2' and others 'flat rates' (in case of)
        default:
            $txt =  __('Est delivery: 2-400 days'); // <= Additional text
    }
    return $label . '<br /><small>' . $txt . '</small>';
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested and works
