我使用此代码来更改我的结帐字段布局，使用我在产品页面 [woocommerce_checkout] 中放入的 Woocommerce Checkout 短代码，它看起来不错，但在结帐页面中则不然，1 秒后会变回原始状态。我尝试更改主题并禁用除 Woocommerce 之外的所有插件，仍然发生。如何解决这个问题？

/**
 Remove all possible fields
 **/
function wc_checkout_fields( $fields ) {
echo '<style>       
.woocommerce-additional-fields {
    display: none;
}
.woocommerce-checkout #customer_details>* {
    margin-bottom: 1rem !important;
}
</style>';
$fields['billing']['billing_first_name']['priority'] = 10;
$fields['billing']['billing_first_name']['label'] = 'Name';
$fields['billing']['billing_first_name']['class'] = array( 'form-row-wide' );

$fields['billing']['billing_address_1']['priority'] = 20;
$fields['billing']['billing_address_1']['label'] = 'Address';

$fields['billing']['billing_country']['priority'] = 30;
$fields['billing']['billing_country']['label'] = 'Country';
$fields['billing']['billing_country']['class'] = array( 'form-row-first' );

$fields['billing']['billing_state']['priority'] = 40;
$fields['billing']['billing_state']['label'] = 'State';
$fields['billing']['billing_state']['class'] = array( 'form-row-last' );

$fields['billing']['billing_city']['priority'] = 50;
$fields['billing']['billing_city']['label'] = 'City';
$fields['billing']['billing_city']['class'] = array( 'form-row-first' );

$fields['billing']['billing_postcode']['priority'] = 60;
$fields['billing']['billing_postcode']['label'] = 'Postcode';
$fields['billing']['billing_postcode']['class'] = array( 'form-row-last' );

$fields['billing']['billing_phone']['priority'] = 70;
$fields['billing']['billing_phone']['label'] = 'Phone';
$fields['billing']['billing_phone']['class'] = array( 'form-row-first' );

$fields['billing']['billing_email']['priority'] = 80;
$fields['billing']['billing_email']['label'] = 'Email';
$fields['billing']['billing_email']['class'] = array( 'form-row-last' );

unset( $fields['billing']['billing_last_name'] );
unset( $fields['billing']['billing_address_2'] );
unset( $fields['billing']['billing_company'] );
unset( $fields['order']['order_comments'] );

return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'wc_checkout_fields' );
