在 Woocommerce 中不需要结帐运输邮政编码字段

Question

所以我按照以下说明操作：链接更改邮政编码的必填字段。

add_filter( 'woocommerce_billing_fields', 'wc_optional_billing_fields' );
function wc_optional_billing_fields( $address_fields ) {
    $address_fields['shipping_postcode']['required'] = false;

    return $address_fields;
}

不幸的是，它没有更改所需的字段，而是创建了第二个字段： Image

谁能指出这里的问题是什么？

Answer 1

That happens because you are using woocommerce_billing_fields hook filter that is managing only billing fields for a shipping postcode field…

You could try to use woocommerce_shipping_fields filter hook, but it will not work because the postcode checkout field is a very special field that can only be set to not required using the following hooked function:

add_filter( 'woocommerce_default_address_fields', 'customise_postcode_fields' );
function customise_postcode_fields( $address_fields ) {
    $address_fields['postcode']['required'] = false;

    return $address_fields;
}

如您所见，它同时作用于计费和运输邮政编码字段。显然不可能使它仅用于计费和运输字段的运输邮政编码字段。
