   Hi everyone, I am trying to list my custom taxonomies with get_categories() function. It's working fine in page.php file but it's not working in function.php file. If i won't use any query string in the function, it's listing my post categories fine in function.php. What's wrong? Need help ASAP, thanks.

   My code;

   <br />
   print_r(get_categories('taxonomy=slideshow-categories&post_type=slideshow'));<br />

   The result in function.php (not working);

   <br />
   Array<br />
   (<br />
       [errors] => Array<br />
           (<br />
               [invalid_taxonomy] => Array<br />
                   (<br />
                       [0] => Invalid Taxonomy<br />
                   )</p>
   <p>        )</p>
   <p>    [error_data] => Array<br />
           (<br />
           )</p>
   <p>)<br />

   The result in page.php (working fine);

   The problem looks to be this part post_type=slideshow as post_type is not an argument for get_categories(), post_type is an argument for get_pages()

   I am trying to list my custom taxonomies with get_categories() function

   Have a look at get_terms()

   Have a look at WP_Query Taxonomy_Parameters

   Hi mate, thanks for response. It's not working when i remove the post_type argument too. I just checked for get_terms() but the result is the same, it's working fine in page.php file (or any template file), but not in function.php file.

   
   print_r(get_terms('slideshow-categories'));
   

   result for function.php; (not working)

   
   WP_Error Object
   (
       [errors] => Array
           (
               [invalid_taxonomy] => Array
                   (
                       [0] => Invalid Taxonomy
                   )
   
           )
   
       [error_data] => Array
           (
           )
   
   )
   

   and the result which I expect in page.php file (working fine)

   
   Array
   (
       [0] => stdClass Object
           (
               [term_id] => 15
               [name] => Slideshow G1
               [slug] => slideshow-g1
               [term_group] => 0
               [term_taxonomy_id] => 15
               [taxonomy] => slideshow-categories
               [description] =>
               [parent] => 0
               [count] => 2
           )
   
       [1] => stdClass Object
           (
               [term_id] => 16
               [name] => Slideshow G2
               [slug] => slideshow-g2
               [term_group] => 0
               [term_taxonomy_id] => 16
               [taxonomy] => slideshow-categories
               [description] =>
               [parent] => 0
               [count] => 1
           )
   
       [2] => stdClass Object
           (
               [term_id] => 17
               [name] => Slideshow G3
               [slug] => slideshow-g3
               [term_group] => 0
               [term_taxonomy_id] => 17
               [taxonomy] => slideshow-categories
               [description] =>
               [parent] => 0
               [count] => 1
           )
   
   )

   In fucntions.php, are you trying print_r(get_terms('slideshow-categories')); before the taxonomy has been added?

   P.s. - You need to use a pastebin for long chunks of code/output.
