如何为自定义帖子类型添加自己的主题模板？

Question

I have some post type, but now I need to add certain templates like in pages section.

function products_init() {
  $args = array(
    'label' => 'Products',
    'capability_type' => 'page',
    'menu_icon' => 'dashicons-cart',
    'taxonomies' => array('category'),
    'rewrite' => array('slug' => 'products'),
    'hierarchical'        => false,
    'public'              => true,
    'show_ui'             => true,
    'menu_position'       => 4,
    'can_export'          => true,
    'has_archive'         => true,
    'exclude_from_search' => false,
    'publicly_queryable'  => true,
    'query_var' => true,
    'supports' => array('title', 'editor', 'thumbnail', 'page-attributes')
  );
  register_post_type('products', $args);
}
add_action('init', 'products_init');

As the codex mentioned, you need to add two files to display custom post type.

archive-{post_type}.php
single-{post_type}.php

If you got a 404 error, you could try to call flush_rewrite_rules() in functions.php and refresh your page. If everything is ok, remove flush_rewrite_rules() immediately.

Otherwise you could flush reweire rules from dashboard -> Settings->Permalink page. Click on save button and then check if you can see the page. Save permalink settings will also call flush_rewrite_rules().
