   I need help to filter out and use single post templates for custom taxonomies.

   I use a very simple and powerful filter in single.php to use single post templates for ex. posts in a specific category. I do not get it to work properly for custom taxonomies tho. I have a custom taxonomy called "artikelbredd" and have posts to witch I added the taxonomy term "fullbreddsartikel". This code does not take effect for posts with the requsted custom taxonomy term:

   This is my single.php:

   <?php
   $post = $wp_query->post;
   	if ( is_tax('artikelbredd', 'fullbreddsartikel') ) {include(TEMPLATEPATH . '/single-fullbreddssida.php');}
   	elseif ( has_category('bloggare1') ) {include(TEMPLATEPATH . '/templates/single-bloggare1.php');}
   	else {include(TEMPLATEPATH . '/single-default.php');
   	}
   ?>

   This is my custom taxonomy code snippet in functions.php:

   add_action( 'init', 'build_taxonomies', 0 );  
   
   function build_taxonomies() {
       register_taxonomy( 'placering', 'post', array( 'hierarchical' => true, 'label' => 'Placering och artikelbredd', 'query_var' => true, 'rewrite' => true ) );
       register_taxonomy( 'typsnitt', 'post', array( 'hierarchical' => true, 'label' => 'Typsnitt i löpsedeln', 'query_var' => true, 'rewrite' => true ) );
       register_taxonomy( 'artikelbredd', 'post', array( 'hierarchical' => true, 'label' => 'Artikelbredd', 'query_var' => true, 'rewrite' => true ) );
   }

   If I use this code instead in single.php:
   

   <?php
   $post = $wp_query->post;
   	if ( array(
               'taxonomy' => 'artikelbredd',
               'terms' => array('fullbreddsartikel'),
               'field' => 'slug'
   
           ) ) {include(TEMPLATEPATH . '/single-fullbreddssida.php');}
   	elseif ( has_category('bloggare1') ) {include(TEMPLATEPATH . '/templates/single-bloggare1.php');}
   	else {include(TEMPLATEPATH . '/single-default.php');
   	}
   ?>

   It will use the single post template "single-fullbreddssida.php", but it wont pass to "single-default.php" to posts without that custom taxonomy asigned to it - the default post or the elseif statement with the template "single-bloggare1.php". And array filter above cannot be correct either because it uses "single-fullbreddssida.php" to every posts nomatter category or taxonomy value.

   Im open to use filter code in functions.php to, but if it is possible to solve via single.php I would prefer that as it is a very simple and flexible way to add multiple filters and works great for tags and categories.

   Would be greatful for any help!

   I would use template-parts:

   if ( is_tax( 'artikelbredd', 'fullbreddsartikel' ) ) {
   
         get_template_part( 'single', 'fullbreddsartikel' );
   
      }

   It's build in and easy as pie:

   Try it with https://codex.wordpress.org/Function_Reference/has_term
   something like this [untested]:
   

   if(has_term( 'fullbreddsartikel', 'artikelbredd', $post->ID )) {
   //do stuff
   }
   elseif(has_term( 'bloggare1', 'category', $post->ID )) {
   // do stuff
   } else {
   // do stuff
   }

   Because you're on single.php the $post object should be available outside the loop. To check:
   

   echo $post->ID;

   Hi!

   I did not try much with towonders suggestion, it may work.

   At first it did not work with keesiemeijer suggestion either. The problem was that term names are case-sensitive, so type carefully!

   My taxonomys term was "Fullbreddsartikel" with an F instead of an f (even tho the permalink for it was in lowercases). Now it works great with this code:

   <?php
   $post = $wp_query->post;
   	if ( has_term('Fullbreddsartikel', 'artikelbredd', $post->ID ) ) {include(TEMPLATEPATH . '/single-fullbreddsartikel.php');}
   	elseif ( has_term( 'bloggare1', 'category', $post->ID )) {include(TEMPLATEPATH . '/templates/single-bloggare1.php');}
   	else {include(TEMPLATEPATH . '/single-default.php');
   	}
   ?>

   Thank you very much for your help!

   Hi! look this...

   add_filter('single_template', 'single_template_terms');
   function single_template_terms($template) {
       foreach( (array) wp_get_object_terms(get_the_ID(), get_taxonomies(array('public' => true, '_builtin' => false))) as $term ) {
           if ( file_exists(TEMPLATEPATH . "/single-{$term->slug}.php") )
               return TEMPLATEPATH . "/single-{$term->slug}.php";
       }
       return $template;
   }

   @ Robert
   this is Great!! thanks!

   For folks that don't know all the way.
   This is a function that uses your 'taxonomies' and lets you make a single-'taxonomy'.php file. That way you can have different 'single' pages. Add this code to your functions.php file.

   add_filter('single_template', 'single_template_terms');
   function single_template_terms($template) {
       foreach( (array) wp_get_object_terms(get_the_ID(), get_taxonomies(array('public' => true, '_builtin' => false))) as $term ) {
           if ( file_exists(TEMPLATEPATH . "/single-{$term->slug}.php") )
               return TEMPLATEPATH . "/single-{$term->slug}.php";
       }
       return $template;
   }

   thank you for this filter function!

   If you modify this filter you can use it also to display a single.php for a 'Post Format' like aside or video in a custom single-'post_format'.php

   See my post about this here:
