Use parent post excerpt if summary is empty in roundup list

Hi there,

You’re right. The filter only gets applied if there actually is any output at the moment. It would make sense to change that for a next update.

We do have the wprm_recipe_field filter hook as well. That could be used to change what the $recipe->summary() function returns:

function adjust_recipe_summary( $value, $field, $recipe ) {
if ( 'summary' === $field ) {
if ( ! $value ) {
$parent_post_id = $recipe->parent_post_id();
if ( $parent_post_id ) {
...
}
}
}
return $value;
}
add_filter( 'wprm_recipe_field', 'adjust_recipe_summary', 10, 3 );
