Conditional Statement custom post type category

3 comments

1. is_category() does not work on custom taxonomy archive pages. The correct conditional tag here is is_tax() which takes the name of the taxonomy as first parameter and a string|int|array of term name/s, slug/s or ID/s as second parameter.

   So your whole conditional statement can look something like :

   if ( is_tax( 'my_taxonomy', 'slug-name-of-the-term') ) {
       echo 'My text';
   }
   

   EDIT

   In addition, to test whether a post belongs to a specific term, you should use has_term() to test for the specific term

   global $post; 
   if (    ( $post->post_type == 'myposttype' ) 
        && has_term( 'slug-name-of-the_term', 'my_taxonomy' )
   ) {
       echo 'My text';
   }

2. The conditional is_* functions work on query, not on current post. In other words they tell you things about page you are on, however not about the current post.

   • is_category() will check if current page is category archive
   • has_category() will check if post has specific category assigned

   From your description I suspect you mean the latter.

3. Refer to this codex for detailed understanding:
   https://codex.wordpress.org/Function_Reference/get_categories

   You can do something like this:

           $args = array(
                   'taxonomy'     => **$your_taxonomy**,
                   'orderby'      => name,
                   'title_li'     => $title,
           );
           $sub_cats = get_categories( $args );
           if( !empty($sub_cats) ) {
            // echo our stuff
           }
