向Wordpress菜单项显示自定义发布元数据

Question

this is my first post so first of all : hello everybody, glad to be a part of the community. Secondly please escuse-me in advance for all the English mistakes, i'm french ...

Now this is the problem i have with Wordpress as i'm not a good developer for now :

I've created a custom post type based on the page model named 'Projects' for a more friendly display in the admin :

add_action( 'init', 'create_post_type' );

function create_post_type() {
    register_post_type( 'Projects', array(
        'labels' => array(
            'name' => __( 'Menu Projects' ),
            'singular_name' => __( 'Project' )
        ),
        'hierarchical' => true,
        'capability_type' => 'page',
        'supports' => array('title','editor','thumbnail','custom-fields'),
        'public' => true,
        'menu_position' => 5,
        'menu_icon' => 'dashicons-art'
    ));
}

Then i've add some custom fields i need :

add_action('wp_insert_post', 'wpc_champs_personnalises_defaut');

function wpc_champs_personnalises_defaut($post_id){
if( $_GET['post_type'] = 'Projects' ){
    add_post_meta(1, 'company', '', true);
    add_post_meta(2, 'année', '', true);
}
return true;
};

And now what I want is to display those post meta values in my menu items , right next to the name of the page !

I've tried different things unsucessfully, so if a Wordpress master could help me, that would be great ! Thanks in advance , have a good day !

When you add the post meta, you should supply the $post_id as the first argument.

add_post_meta( $post_id, 'company', 'value here' );

and when you want to the post meta you can use get_post_meta function

get_post_meta( $post_id, 'company', true );
