How to get all taxonomies of a post type?

Question

How can i get taxonomies of a post type?

Suppose i have a post type 'event' now i need to find out the list of taxonomies that are attached to this post type.

Answer 1

Hey guys i think i got it! After looking at couple of functions in taxonomy.php file in wordpress i have found this function get_object_taxonomies(); which did the tricks :)

Here is the function

function get_post_taxonomies($post) {
    // Passing an object
    // Why another var?? $output = 'objects'; // name / objects
    $taxonomies = get_object_taxonomies($post, 'objects');

    /*// Passing a string using get_post_type: return (string) post, page, custom...
    $post_type  = get_post_type($post);
    $taxonomies = get_object_taxonomies($post_type, 'objects');*/

    /*// In the loop with the ID
    $theID      = get_the_ID();
    $post_type  = get_post_type($theID);
    $taxonomies = get_object_taxonomies($post_type, 'objects');*/

    // You can also use the global $post

    // edited to fix previous error $tazonomies
    // edited to force type hinting array
    return (array) $taxonomies; // returning array of taxonomies
}

Answer 2

get_categories will do the job.

get_categories('taxonomy=taxonomy_name&type=custom_post_type'); 

Answer 3

Have you tried anything? something like this?

<?php 

$args=array(
  'object_type' => array('event') 
); 

$output = 'names'; // or objects
$operator = 'and'; // 'and' or 'or'
$taxonomies=get_taxonomies($args,$output,$operator); 
if  ($taxonomies) {
  foreach ($taxonomies  as $taxonomy ) {
    echo '<p>'. $taxonomy. '</p>';
  }
}
?>
