thank you, Mike!
but looks like answer even much easier)
found:
function filter_custom_details_header($heading) {
return 'My Customer Details Heading';
}
add_filter('woocommerce_email_custom_details_header', 'filter_custom_details_header');
So $order was optional.
Hi Lorro! I have some issue with this part too!
I found filter
$heading = apply_filters( 'woocommerce_email_custom_details_header', $heading, $sent_to_admin, $order );
and added next function
//change email header customer info
add_filter( 'woocommerce_email_custom_details_header', 'change_email_header');
function change_email_header( $heading, $sent_to_admin = false, $order ) {
global $order;
$heading = $sent_to_admin ? __( 'Info', 'woocommerce' ) : __( 'Your info', 'woocommerce' );
return $heading;
}
But it’s return an error:
Warning: Missing argument 3 for change_email_header()
Can you help me and tell how in this case defined $order?
