Wordpress Custom Post Type not Showing in Appearance > Menu

Question

Yep, I have been searching all over, and seems the only reason this should be happening is because it is not checked in the Screen Options menu in WordPress. My problem is, the custom post type is not showing in Screen Options so I was wondering if someone could have a look at my code and see if I'm doing some thing wrong.

function my_custom_post_maryland() {
$labels = array(
    'name'               => _x( 'Maryland', 'post type general name' ),
    'singular_name'      => _x( 'Maryland', 'post type singular name' ),
    'add_new'            => _x( 'Add New', 'Maryland page' ),
    'add_new_item'       => __( 'Add New Maryland Page' ),
    'edit_item'          => __( 'Edit Page' ),
    'new_item'           => __( 'New Page' ),
    'all_items'          => __( 'All Pages' ),
    'view_item'          => __( 'View Page' ),
    'search_items'       => __( 'Search Maryland Pages' ),
    'not_found'          => __( 'No Maryland pages found' ),
    'not_found_in_trash' => __( 'No Maryland pages found in the Trash' ), 
    'parent_item_colon' => __( 'Parent Page' ),
    'parent_item_colon'  => '',
    'menu_name'          => 'Maryland'
);

$args = array(
    'labels'        => $labels,
    'description'   => 'Holds our Maryland pages specific data',
    'public'        => true,
    'menu_position' => 5,
    'supports'      => array( 'title', 'editor', 'thumbnail', 'excerpt' ),
    'show_ui'       => true,
    'has_archive'   => true,
    'show_in_nav_menus' => true
);
register_post_type( 'maryland', $args ); 
}
add_action( 'init', 'my_custom_post_maryland' );

Answer 1

You still need to add it to the menu using

function setup_bonsai_theme_admin_menus()
{
    add_menu_page('MyTheme settings', 'My Theme Settings', 'manage_options', 
        'my_theme_settings', 'my_page_settings');

    add_submenu_page('my_theme_settings', 
        'My Page Elements', 'maryland', 'manage_options', 
        'my_questions_settings', 'my_maryland_settings');
}

and

add_action('admin_menu', 'setup_bonsai_theme_admin_menus');

and

function my_page_settings()
{
    ?>
    <div class="wrap">
    <h2>There are no theme options at this stage.</h2>
    </div>
    <?php

}

function my_maryland_settings()
{
    ?>
    <div class="wrap">
    <h2>Maryland</h2>
    </div>
    <?php
}

After that you also need to add a new template file for single posts as well as archive posts, etc, so you can actually view them. The wordpress codex for 'theme templates' should help you there, as it's quite easy.

Answer 2

Here's a working example.

functions.php

    <?php
    function setup_bonsai_theme_admin_menus()
    {
        add_menu_page('SCHS Theme settings', 'SCHS Theme Settings', 'manage_options', 
            'SCHS_theme_settings', 'SCHS_page_settings');

        add_submenu_page('SCHS_theme_settings', 
            'SCHS Page Elements', 'Questions', 'manage_options', 
            'SCHS_questions_settings', 'SCHS_questions_setings'); 
        add_submenu_page('SCHS_theme_settings', 
            'SCHS Page Elements', 'Answers', 'manage_options', 
            'SCHS_ansers_settings', 'SCHS_answers_settings'); 

    }

    function SCHS_page_settings()
    {
        ?>
        <div class="wrap">
        <h2>There are no theme options at this stage.</h2>
        </div>
        <?php

    }

    function SCHS_questions_setings()
    {
        ?>
        <div class="wrap">
        <h2>Questions</h2>
        </div>
        <?php
    }
    function SCHS_answers_settings()
    {
        ?>
        <div class="wrap">
        <h2>Answers</h2>
        </div>
        <?php
    }
    function question_custom_post()
    {
        $labels = array(
            'name'               => _x( 'Questions', 'post type general name' ),
            'singular_name'      => _x( 'Questions', 'post type singular name' ),
            'add_new'            => _x( 'Add New', 'book' ),

            'not_found'          => __( 'No question found' ),
            'not_found_in_trash' => __( 'No question found in the trash' ), 
            'parent_item_colon'  => '',
            'menu_name'          => 'SCHS Questions'
        );
        $args = array(

Answer 3

You also need to register the men u in your functions.php in theme:

add_action( 'after_setup_theme', 'register_my_menu' );

function register_my_menu() {
   register_nav_menu( 'primary', __( 'Primary Menu', 'theme-slug' ) );
}
