Hi!
If the normal description is showing, then the “if ( $checkboxes ) …” part of the code is not executed. I think the ACF get_field() function needs a post ID as well. Try this modification of their suggestion:
[php]
add_filter( ‘asp_results’, ‘asp_checkbox_to_results’, 1, 1 );
asp_checkbox_to_results( $results ) {
foreach ($results as $k=>$v) {
// Get the field
$checkboxes = get_field(‘my_checkbox_list’, $v->id);
// Append if exists
if( $checkboxes ){
$checkbox_string = implode(‘, ‘, $checkboxes);
$results[$k]->content .= " – " . $checkbox_string;
}
}
return $results;
}
[/php]
