This thread is resolved. Here is a description of the problem and solution.
Problem: I have a repeating field that includes simple text strings. I would like to display the values of that field in alphabetical order.
Solution: It could be complicated if the field accepts HTML, or if special characters or complex fields are considered. If you just want a basic text comparison on a simple Types field, you can add this custom shortcode to your child theme's functions.php file or create a new snippet in Toolset > Settings > Custom Code:
add_shortcode( 'ts-sort-multi-field-values', 'ts_sort_multi_field_values_func');
function ts_sort_multi_field_values_func( $atts, $content ) {
global $post;
$a = shortcode_atts( array(
'direction' => 'ASC',
'slug' => '',
'glue' => ', ',
), $atts );
$vals = get_post_meta($post->ID, 'wpcf-' . $a['slug']);
if($a['direction'] == 'ASC')
usort($vals, "alpha_vals_asc_cmp");
if($a['direction'] == 'DESC')
usort($vals, "alpha_vals_desc_cmp");
return implode($a['glue'], $vals);
}
function alpha_vals_asc_cmp($a, $b)
{
$stra = strtolower($a);
$strb = strtolower($b);
$res = 0;
if ( $stra < $strb) {
$res = 1;
}
return $res;
}
function alpha_vals_desc_cmp($a, $b)
{
$stra = strtolower($a);
$strb = strtolower($b);
$res = 0;
if ( $stra > $strb) {
$res = 1;
}
return $res;
}
Then use the shortcode like this to display a sorted list of the field values:
[ts-sort-multi-field-values slug='your-field-slug' direction='ASC' glue=', ']
Replace your-field-slug with the slug of your custom field. Direction can be ASC or DESC, and glue is the separator between values.
