Hi, with some help from WP.org I managed to sort this out yesterday. For the record, the final code that we ended up using is the following:
text/x-generic page-10787.php
PHP script text
<?php get_header(); ?>
<section class="content">
<?php get_template_part('inc/page-title'); ?>
<div class="pad group">
<div class="entry">
<div class="entry-inner">
<?php the_content(); ?>
<?php wp_link_pages(array('before'=>'<div class="post-pages">'.__('Pages:','hueman'),'after'=>'</div>')); ?>
</div>
<div class="clear"></div>
</div><!--/.entry-->
<?php
$posts = get_posts( array(
'numberposts' => -1,
'meta_key' => 'elokuvat_l',
'order'=> 'ASC'
) );
if( $posts ) {
echo '<ul>';
$temporary_list = array();
foreach( $posts as $post ) {
$film_names = get_field( 'elokuvat_l', $post->ID );
$film_names_array = preg_split( '/\r\n|\r|\n/', $film_names );
foreach( $film_names_array as $film_name ) {
$temporary_list[] = array( 'post_id' => $post->ID, 'film_name' => $film_name );
}
}
// custom sort function
usort( $temporary_list, function ( $a, $b ) {
return strcasecmp($a['film_name'], $b['film_name']); // compare two strings ignoring case
});
// loop and display
foreach( $temporary_list as $film_name ){
echo '<li><a href="' . get_permalink($film_name['post_id']) . '">' . $film_name['film_name'] . '</a></li>';
}
echo '</ul>';
}
?>
</div><!--/.pad-->
</section><!--/.content-->
<?php get_sidebar(); ?>
<?php get_footer(); ?>
