循环多个帖子类型和帖子foreach

Question

What i want to make:

I want to make a navigation menu where every dropdownbar is its own post type.

1. Movie
   • movie1
   • movie2
2. Book
   • book1
   • book2
3. Game
   • game1
   • game2

---

What i've made so far:

I'm not the best at php yet, but i tried to work something out:

echo "<ul class="menu">";

$post_type = get_post_types( array('Movie', 'Book', 'Game') );

foreach( $post_type as $type ) {

    $args = array(
        'post_type' => $type
    );

    echo "<li>".$type."<ul class="dropdown">";

    $posts = get_posts( $args );

    if( $posts ) {

        foreach( $posts as $post ) {

            echo "<li>".get_the_title( $post->ID, 'title' )."</li>";

        }
    echo "</ul></li>";
    }
}
echo "</ul>";

Question:

Is there a smarter way to make the dropdownmenu? or what can i do to make it work?

Answer 1

There's nothing wrong with that approach, except that you shouldn't use get_post_types() - just an array of the post type names will do.

As it stands at the moment, 'post_type' => $type will pass an array to post_type, when it should be a string.

Also, echo "<li>".$type."<ul class="dropdown">"; should be inside your if( $posts ) { before the foreach.
