Browsing custom taxonomy terms on WordPress - wordpress

Question

I ran into a little problem and I might need your help to sort it out.
I an building a website that uses custom taxonomies and tags posts accordingly. So, there is a page like http://example.com/custom-taxonomy/term that displays all the posts tagged with "term".
The visitor should be able to go to http://example.com/custom-taxonomy/ and see a lists of all the terms that are used inside that custom taxonomy in order to browse them. This list should also be "paginated" since some taxonomies could have quite a lot of terms in them.
Any ideas on how I should handle this?
Thanks a bunch!

Answer 1

I'll answer my own question here, maybe it will help others.
I have created a custom page template that uses get_terms to get the terms for a specific taxonomy and iterates through them displaying them in the desired manner.
I then created a page with the exact same slug as the main taxonomy slug (http://example.com/actors in this case) and thus when going to /actors/ you actually see the page created that acts as an index page for the taxonomy. You can see it in effect at http://couch.ro/actori/
In the actual code I am also using the Taxonomy Images plugin for having images on the actual tags so the get_terms is executed through the apply_filter() function. You have the full code for the template below. Any feedback is highly appreciated!
<?php

You can use query_posts function like this
$termname = get_query_var('pagename'); //custom-taxonomy term
query_posts(array(
'post_type' => POST_TYPE,
'showposts' => $limit,
'custom-taxonomy' => $termname // use $term1.','.$term2.','.$term3 to get multiple terms posts
));
see Documentation at Wordpress
To get all Terms under Custom Taxonomy try this you will have full control.
global $wpdb;
$taxonomy = CUSTOM_CAT_TYPE;
$table_prefix = $wpdb->prefix;
$wpcat_id = NULL;
//Fetch category or Term as said
$wpcategories = (array) $wpdb->get_results("
SELECT * FROM {$table_prefix}terms, {$table_prefix}term_taxonomy
WHERE {$table_prefix}terms.term_id = {$table_prefix}term_taxonomy.term_id
AND {$table_prefix}term_taxonomy.taxonomy ='" . $taxonomy . "' and {$table_prefix}term_taxonomy.parent=0 ORDER BY {$table_prefix}terms.name ASC");
$wpcategories = array_values($wpcategories);
foreach ($wpcategories as $wpcat) {
$termid = $wpcat->term_id;
$name = $wpcat->name;
$termprice = $wpcat->term_price;
$tparent = $wpcat->parent;
}
