需要其他注释，取决于运输类型

如何解决需要其他注释，取决于运输类型

如果要选择包裹点取货运输方式（flat_rate：47），我正在尝试在结帐时将“附加说明”作为必填字段。如果我不使用特定的ID（47），它会起作用，并且要求在所有统一费率送货方式中填写订单说明。但我希望它只能在flat_rate：47航运上工作。到目前为止，这是我的代码，但无法正常工作。知道我在做什么错吗？

from netCDF4 import Dataset
import glob

def ncdump(nc_fid,verb=True):
    '''
    ncdump outputs dimensions,variables and their attribute information.
    The information is similar to that of NCAR's ncdump utility.
    ncdump requires a valid instance of Dataset.

    Parameters
    ----------
    nc_fid : netCDF4.Dataset
        A netCDF4 dateset object
    verb : Boolean
        whether or not nc_attrs,nc_dims,and nc_vars are printed

    Returns
    -------
    nc_attrs : list
        A Python list of the NetCDF file global attributes
    nc_dims : list
        A Python list of the NetCDF file dimensions
    nc_vars : list
        A Python list of the NetCDF file variables
    '''
    def print_ncattr(key):
        """
        Prints the NetCDF file attributes for a given key

        Parameters
        ----------
        key : unicode
            a valid netCDF4.Dataset.variables key

解决方法

正确的代码：

// Validate mandatory "Order notes" field for "Parcel pickup point" shipping methods
add_action( 'woocommerce_checkout_process','flat_rate_order_comment_validation',20 );
function flat_rate_order_comment_validation() {
    $chosen_shipping = WC()->session->get( 'chosen_shipping_methods' )[0];
       if ( $chosen_shipping == 'flat_rate:47' && empty($_POST['order_comments']) ){
        wc_add_notice( __( "You need to fill up \"Order notes\" with some details.","woocommerce" ),'error' );
    }
}
