如何在管理菜单中添加自定义帖子类型（） _WordPress开发

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' );
