Don't display post if post has empty body

Question

I have a custom post type sites registered via register_post_type and my front page displays my latest posts. Including posts from sites.

Is there any way I can set it up so that posts from sites (custom post type) that have no post body (no content) will NOT be displayed?

The body of the custom post type is not important, the title is. I introduced custom fields for my custom post type. I make a list from custom posts and majority of them do not have any body. So I do not want to display them. It will only make the web harder to read. I want to display only custom posts that have body.

I have not modify the loop.

How can I modify the loop (introduce custom query) as a part of plugin?

Answer 1

By default in Wordpress if you create a new post, or custom post type based on post, and fill in the title but no body and press "Publish" it will save it as a draft instead of actually publishing it. If the post is saved as a draft it won't show up in your list of posts during the loop.

Can you elaborate more on why you're trying to accomplish this? There might be an easier solution for the bigger goal.

However, if you do want it to work exactly as specified, you'll To specifically modify which posts go through the loop, you would need to run a custom query.

Did you already modify the loop by adding parameters or doing a custom query? If so, please post that for a start.

Just take the $post object inside your loop and write

if ( ! $post->post_content )
    continue;

to skip the current "round" of your loop if the post has no content.
