WordPress A-Z taxonomy list

Taxonomies are great to group and organize content. We’ll take a look on how to make an A-Z list of entries in a given taxonomy in WordPress.
When we build Indiemondo we made a taxonomy for tagging films up with festivals. With over a thousands festivals simply making a long list and expect vivistors to browse thorugh was a no go.
We wanted to things:
- Grouping festivals by first letter
- Making an easy in page search – this will be coming up in a feature post
Copy and paste the code below into a page template file and replace ‘YOUR TAXONOMY’ with the name of your taxonomy.
As for the array of arguments check out the WordPress codex article.
$list = '';
$groups = array();
$tags = get_terms('YOUR TAXONOMY',$args);
if( $tags && is_array( $tags ) ) {
foreach( $tags as $tag ) {
$first_letter = strtoupper( $tag->name[0] );
$groups[ $first_letter ][] = $tag;
}
if( !empty( $groups ) ) {
foreach( $groups as $letter => $tags ) {
$list .= "<div><h3>" . $letter . "</h3><ul>";
foreach( $tags as $tag ) {
$list .= '<li><a href="/YOUR TAXONOMY/'.$tag->slug.'">'.$tag->name.'</a></li>';
}
$list .= '</ul></div>';
}
$list .= '';
}
}
echo $list;
This code will loop through the terms and create a group for the first character and create the a div with an h3 for the title of the group.
