WooCommerce结账页面删除字段

可以在WooCommerce结账页面删除一些不必要的字段

移除代码参考如下：

/**
 Remove all possible fields
 **/
function wc_remove_checkout_fields( $fields ) {
    // Billing fields
    unset( $fields['billing']['billing_company'] );
    unset( $fields['billing']['billing_email'] );
    unset( $fields['billing']['billing_phone'] );
    unset( $fields['billing']['billing_state'] );
    unset( $fields['billing']['billing_first_name'] );
    unset( $fields['billing']['billing_last_name'] );
    unset( $fields['billing']['billing_address_1'] );
    unset( $fields['billing']['billing_address_2'] );
    unset( $fields['billing']['billing_city'] );
    unset( $fields['billing']['billing_postcode'] );

    // Shipping fields
    unset( $fields['shipping']['shipping_company'] );
    unset( $fields['shipping']['shipping_phone'] );
    unset( $fields['shipping']['shipping_state'] );
    unset( $fields['shipping']['shipping_first_name'] );
    unset( $fields['shipping']['shipping_last_name'] );
    unset( $fields['shipping']['shipping_address_1'] );
    unset( $fields['shipping']['shipping_address_2'] );
    unset( $fields['shipping']['shipping_city'] );
    unset( $fields['shipping']['shipping_postcode'] );

    // Order fields
    unset( $fields['order']['order_comments'] );

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

还可以让某些字段非必填

add_filter( 'woocommerce_billing_fields', 'wc_unrequire_wc_phone_field');
function wc_unrequire_wc_phone_field( $fields ) {
    $fields['billing_phone']['required'] = false;
    return $fields;
}

修改某些字段的label和placeholder

add_filter('woocommerce_checkout_fields', 'custom_override_checkout_fields');
function custom_override_checkout_fields($fields)
{
    unset($fields['billing']['billing_address_2']);
    $fields['billing']['billing_company']['placeholder'] = 'Company Name';
    $fields['billing']['billing_company']['label'] = 'Company Name';
    $fields['billing']['billing_first_name']['placeholder'] = 'First Name';
    $fields['shipping']['shipping_first_name']['placeholder'] = 'First Name';
    $fields['shipping']['shipping_last_name']['placeholder'] = 'Last Name';
    $fields['shipping']['shipping_company']['placeholder'] = 'Company Name';
    $fields['billing']['billing_last_name']['placeholder'] = 'Last Name';
    $fields['billing']['billing_email']['placeholder'] = 'Email Address ';
    $fields['billing']['billing_phone']['placeholder'] = 'Phone ';
    return $fields;
}
