 * hey there!
 * i code a plugin.
    in this little piece of code i want to create an array which
   contains the title of each post as Key, this actually works great. but the post
   id is just not added as value to each key. Dont get the point in it, been looking
   for mistakes for ages, or at least felt like that.
 *     ```
       $heldengeschichtenDropdown = array( 'Platzhalter' => 0 );
       $args = array( 'category' => 5 );
       $heldengeschichten = get_posts( $args );
       foreach ( $heldengeschichten as $post ) : setup_postdata( $post );
       	$arraykey = get_the_title($post);
       	$value = $id;
       	$heldengeschichtenDropdown[$arraykey] = $value;
       endforeach;
       wp_reset_postdata();
       ```

 * [@alexejp](https://wordpress.org/support/users/alexejp/), try including `global
   $post;` in your code, per [the Codex article for setup_postdata](https://codex.wordpress.org/Function_Reference/setup_postdata)(
   there are examples in that article if you’re not sure where you should put it).

       $value = $post->ID;
       ```

 * Thanks very much for your help!
 * including
    `global $post;` didn’t help. But `$post->ID;` makes the magic happen!
 * that `global $post;` didn’t work quite surprised me pretty much.
 * whats about this arrow `->` notation? is it like $post is an object with attributes
   and one of these atts is ID?

 * Exactly! Though with objects, the values are usually referred to as ‘properties’
   instead of ‘attributes’, but it’s just semantics.
