categories - Category.php template for custom posts

admin管理员组

文章数量:1391736

I'm trying to use my category.php file to display all posts of a certain custom post type (say "Company") with a given category. However, when I try to use it by navigating to domain/category/company/category1, which is the link automatically generated by wp_list_categories(), no posts appear.

The code I'm using is:

<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'type-company', get_post_format() ); ?>
<?php endwhile; ?>

What am I doing wrong?

I figured it out! For anyone having the same problem, I solved it by adding

$cat_id = get_query_var('cat'); 
query_posts("post_type=company&cat=$cat_id");

right in front of the loop. Anyone having the same problem would probably also benefit from looking at this, too.

The correct way is to use pre_get_posts for that.

You can either add to show at the search.php and other pages from template hierarchy, like so:

add_action('pre_get_posts', function($query) {
    if ( ! is_admin() && $query->is_main_query() ) {

        if ( is_archive() || is_category() ) {
            $query->set( 'post_type', 'company' );
        }

        if ( $query->is_search() ) {
            $query->set( 'post_type', array( 'company' ) );
        }
    }
});

To understand more about pre_get_posts() you should watch this talk of Andrew Nacin (one of the leader developers of WP)

Are you using the core category taxonomy, by applying it to your Custom Post Type, or have you defined a custom taxonomy?

If you're using a custom taxonomy, you need to use the template file taxonomy-{taxonomy}.php, or taxonomy-{taxonomy}-{term}.php.

But really, using category.php or taxonomy.php really may not be what you want to do. Have you tried using archive-{post-type}.php, for displaying the archive index list of posts from your Custom Post Type?

You also have an issue with this:

<?php get_template_part( 'type-company', get_post_format() ); ?>

The Post Format taxonomy only applies to the Post post-type; not to any, arbitrary post-type. Again: did you custom-apply the Post Format taxonomy to your Custom Post Type?

EDIT

Note: you may need to modify the Loop query in category.php and/or tag.php, in order to display your CPTs.
