Okay, I see how this works now. Without coding this is not possible, but it should not be too difficult whatsoever.
Your code looks surprisingly perfectly fine to me, very good job – but I might be able to suggest a way based on that so you don’t have to use an additional field.
Instead of that code, try this:
add_filter( 'asp_results', 'asp_add_extra_field_data', 10, 1 );
function asp_add_extra_field_data( $results ) {
foreach ($results as $k=>&$r) {
$slug = $r->post_type;
$taxname = get_field('published_year', $r->id)->name;
$origin = get_field('originator', $r->id)->name;
$enjoyed = get_field('date_enjoyed', $r->id);
$tipwrit = get_field('writer', $r->id)->name;
$enjoydat = get_field('enjoyed_at', $r->id)[0]->post_title;
$tippub = get_field('publication', $r->id)->name;
$strung = $slug . ": " . $taxname . $enjoyed . $tipwrit . ', ' . $origin . $enjoydat . $tippub
}
return $results;
}Please be very careful and have backups! I may have made typos, as I am not able to test this.
PS: Try adding this code via the Code Snippets plugin or to the functions.php file in your theme/child theme directory – make sure to have a full server back-up first for safety. For more details you can check the safe coding guidelines.
