Get posts by menu ID

0 Views

I’m a little stuck here. I have a menu in WordPress with some posts in it.
What I would like is to retrieve all the posts as objects.

I think I’m pretty close, but the SQL query doesn’t seem to work as I want.

This is wat I have so far: 

$querystr = "
SELECT wposts.* FROM wp_posts wposts
LEFT JOIN wp_postmeta wmeta ON wposts.ID = wmeta.post_id
LEFT JOIN wp_term_relationships wrel ON wrel.object_id = wmeta.meta_value
LEFT JOIN wp_terms wterms ON wrel.term_taxonomy_id = wterms.term_id
WHERE wterms.term_id= $menu_id
";

$posts = $wpdb->get_results($querystr, OBJECT);

I’m pretty sure it’s a stupid little SQL logic error, but I realy can’t find it..

  1. I recently needed the same thing, I had menu of categories and I needed to get the categories that in the menu. After a several hours digging in the WP core, I found the
    wp_get_nav_menu_items() function that helped me.

    I finnally came with this, 220 was my menu_id

    $navcat = wp_get_nav_menu_items('220');
    foreach ($navcat as $obj) {
        $catid = $obj->object_id;
        $category = get_category($catid);
        ...
        ...
    }

    So, if you have a nav menu of posts, I assume you can do the same, something like this should work – 

    $nav_items = wp_get_nav_menu_items('220');  
    foreach ($nav_items as $obj) {
        $objid = $obj->object_id;
        $postobj = get_post($objid);

        //do stuff with the post..
    }

    I think it can save you some complexed mySQL query…
