Hi @vierastalo
For something like this, you need to split the entries and then save it to a temporary variable like this:
$temporary_list = array();
foreach($posts as $post){
$film_names = get_field('elokuvat_k', $post->ID);
$film_names_array = preg_split( '/\r\n|\r|\n/', $string );
foreach($film_names_array as $film_name){
$temporary_list[] = array('post_id' => $post->ID, 'film_name' => $film_name);
}
}
After that you need to sort the array using array_multisort() function like sorting a repeater.
foreach( $temporary_list as $i => $row ) {
$order[ $i ] = $row['film_name'];
}
array_multisort( $order, SORT_ASC, $temporary_list );
Then you can loop the $temporary_list variable to show the entries.
I hope this makes sense.
