如何在管理菜单中添加自定义帖子类型？

我的文件是否放在错误的文件夹中？

添加所有这些代码后, 它们最终以文本形式出现在我的管理菜单上。我尝试将其直接放入我的functions.php中, 也将其放入一个名为function.php的文件中, 这就是本教程所说的内容, 我认为这是一个错字。

themes/theme-name/wp-includes/post.php

function ttlm_register_team_custom_type() {
    $labels = array(
        'name'               => _x( 'Teams', 'post type general name', 'your-plugin-textdomain' ), 'singular_name'      => _x( 'Team', 'post type singular name', 'your-plugin-textdomain' ), 'menu_name'          => _x( 'Teams', 'admin menu', 'your-plugin-textdomain' ), 'name_admin_bar'     => _x( 'Team', 'add new on admin bar', 'your-plugin-textdomain' ), 'add_new'            => _x( 'Add New', 'team', 'your-plugin-textdomain' ), 'add_new_item'       => __( 'Add New Team', 'your-plugin-textdomain' ), 'new_item'           => __( 'New Team', 'your-plugin-textdomain' ), 'edit_item'          => __( 'Edit Team', 'your-plugin-textdomain' ), 'view_item'          => __( 'View Team', 'your-plugin-textdomain' ), 'all_items'          => __( 'All Teams', 'your-plugin-textdomain' ), 'search_items'       => __( 'Search Teams', 'your-plugin-textdomain' ), 'parent_item_colon'  => __( 'Parent Teams:', 'your-plugin-textdomain' ), 'not_found'          => __( 'No teams found.', 'your-plugin-textdomain' ), 'not_found_in_trash' => __( 'No teams found in Trash.', 'your-plugin-textdomain' )
    );

    $args = array(
        'labels'             => $labels, 'public'             => true, 'publicly_queryable' => true, 'show_ui'            => true, 'show_in_menu'       => true, 'query_var'          => true, 'rewrite'            => array( 'slug' => 'ttlm_team' ), 'capability_type'    => 'post', 'has_archive'        => true, 'hierarchical'       => false, 'menu_position'      => null, 'supports'           => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
    );

    register_post_type( 'ttlm_team', $args );
}

add_action( 'init', 'ttlm_register_team_custom_type' );

themes/theme-name/functions.php

/*-----------------------------------------------*/
/* Custom Post Types
/*-----------------------------------------------*/
require_once('wp-includes/post.php');

将代码包括在：

<?php

//your functions

?>
