Browsing custom taxonomy terms on WordPress

2 comments

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
   /*
   Template Name: Taxonomy Index
   */
   $slug_to_taxonomy=array('actori'=>'actor','regizori'=>'director');
   $terms_per_page=get_option( 'c2c_custom_post_limits' );
   
   if ($terms_per_page['archives_limit']==0)
   {
       $terms_per_page=get_options('posts_per_page');
   }
   else
   {
       $terms_per_page=$terms_per_page['archives_limit'];
   }
   
   $slug=$post->post_name;
   
   if (!isset($slug_to_taxonomy[$slug]))
   {
       header("Location: /");exit;
   }
   else
   {
       $taxonomy=$slug_to_taxonomy[$slug];
   }
   
   $terms_page=get_query_var('paged');
   if (empty($terms_page))
   {
       $terms_page=1;
   }
   
   $terms=apply_filters( 'taxonomy-images-get-terms', '',array('having_images'=>false,'taxonomy'=>$taxonomy, 'term_args'=>array('offset'=>($terms_page-1)*$terms_per_page,'number'=>$terms_per_page)) );
   
   if (empty($terms))
   {
       header("Location: /");exit;
   }
   
   $processed_terms=array();
   foreach ($terms as $term)
   {
       if (!empty($term->image_id))
       {
           $image_src=wp_get_attachment_image_src($term->image_id,'archive-thumbnail');
           $image_src=$image_src[0];
       }
       else
       {
           $image_src='http://couch.ro/wp-content/uploads/couchie_75.png';
       }
   
       $term_posts=get_posts(array('posts_per_page'=>3,'tax_query'=>array(array('taxonomy'=>$taxonomy,'field'=>'slug','terms'=>$term->slug))));

2. 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;  
   }
