Hi Julia,
You can use the crp_output_list_item plugin hook to alter the output of the related posts lists. Something like this can be used:
function crp_custom_output( $output, $post_id, $relation ) {
// Alter $output using the $relation from this $post_id.
return $output;
}
add_filter( 'crp_output_list_item', 'crp_custom_output', 10, 3 );
Kind regards,
Brecht

hello brecht,
thanks for your quick reply. but i’m afraid i dont know how to use this. i assume it goes in my (child-theme) functions.php, but what part would i need to replace to make it work?
thanks,
julia

Yes, you’d add that in your functions.php file. You’d then check the $relation variable for the ID of the related post and get the custom fields you need. Whatever you return will be shown on the screen.

hello brecht,
my php abilities are just “copy, paste & alter”, but not write anything myself. i searched the wp codex section, but still am not any wiser.
so i still don’t know how to:
“check the $relation variable for the ID of the related post and get the custom fields you need”.
so this seems not to be a plugin-related question, just my lack of understanding of php. i understand that you can’t give support for that.
but as i want to learn: if it would be easy for you to give me a hint, or a code example, i wouldn’t mind 😉
and: “Whatever you return will be shown on the screen.” that would work with both, shortcode or widget, right?
thanks a lot,
julia

You could use something like this:
function crp_custom_output( $output, $post_id, $relation ) {
// Alter $output using the $relation from this $post_id.
if ( isset( $relation['id'] ) ) {
$custom_field = get_post_meta( $relation['id'], 'your-custom-field', true );
if ( $custom_field ) {
$output = '<li><a href="' . $relation['permalink'] . '">' . $relation['title'] . ' - ' . $custom_field . '</a></li>';
}
}
return $output;
}
add_filter( 'crp_output_list_item', 'crp_custom_output', 10, 3 );
One issue might be that the $relation[‘id’] is only set for relations created since our last update.
This will change the output for both the shortcode and the widget.
