custom post type archive template per custom taxonomy term

Question

I want to list all posts with a corresponding template for a custom taxonomy term of a custom post type. To make it easier to understand:

The custom post type is called PUBLICATIONS and has a custom taxonomy called LISTS. Each list template is slighty different, so when all posts are listed on the archive-publications page, posts in term LIST A shall be displayed using Template A, LIST B Template B, and so on.

I've tried this:

<?php
function publikationen_archive() {
    if ( is_archive('publikationen') && is_tax('downloads') ) { get_template_part( 'templates/content-downloads' );
    } elseif ( is_archive('publikationen') && is_tax('sonderbaende-kataloge') ) { 
    get_template_part( 'templates/content-sonderbaende-kataloge' );
    } elseif ( is_archive('publikationen') && is_tax('neuerscheinungen') ) { 
    get_template_part( 'templates/content-neuerscheinungen' );
    } elseif ( is_archive('publikationen') && is_tax('untersuchungen') ) { 
    get_template_part( 'templates/content-untersuchungen' );
    } elseif ( is_archive('publikationen') && is_tax('studien-materialien') ) { 
    get_template_part( 'templates/content-studien-materialien' );
    }
} ?>

which didn't work. Then I came across the filter single_template, template_redirect and template_include but don't really know what to do with them.

Answer 1

I solved it.

SOLUTION:

<?php 
if ( has_term( 'downloads', 'listen', $post->ID ) ) {
    get_template_part( 'templates/content-downloads-vergriffener-baende' ); 
} 
elseif ( has_term( 'untersuchungen', 'listen', $post->ID ) ) { 
    get_template_part( 'templates/content-untersuchungen' ); 
} 
elseif ( has_term( 'studien-materialien', 'listen', $post->ID ) ) { 
    get_template_part( 'templates/content-studien-materialien' ); 
} 
elseif ( has_term( 'sonderbaende-kataloge', 'listen', $post->ID ) ) { 
    get_template_part( 'templates/content-sonderbaende-kataloge' ); 
}
?>

Answer 2

in your post loop. use this code.

<?php while (have_posts()) : the_post(); 
            $post_type = get_post_type(get_the_ID());
            if($post_type !='post'){
                get_template_part('content-' . $post_type, get_post_format());
            }
            else {
               get_template_part( 'content', get_post_format() );
            }
            //If comments are open or we have at least one comment, load up the comment template.
                    // if ( comments_open() || get_comments_number() ) {
                    //  comments_template( '', true );
                    // }
                //endwhile; ?>
            <?php comments_template( '', true ); ?>
        <?php endwhile; // end of the loop. ?>

then create content-publication.php for your post type page structure.
