How to print all posts of a given post-type (CPT) in a given webpage?

Question

I use latest WordPress and I went to GenerateWP and created a new custom post type named "book_pages". I pasted the output in the end of my functions.php. The post-type is available and I can work with it in my site.

I then went to "pages" and added a new page named "all book pages".

I'd like to show trimmed version of all nodes of the "book_pages" CPT under "all book pages".

It should be seem like this:

---

Basically I need just the headline of each webpage to appear in each box under "All book pages" (and each box will link to the relevant book_page).

I'll further style the boxes with CSS.

But I only need to know how to actually print all nodes of my "book_pages" CPT in the "All book pages" page.

Notes:

• You likely noticed that in this book, each page is actually a chapter-page.

You could use get_posts() to get posts of a particular type, then use a for loop to print out links, titles, etc as required.

Maybe put this in a custom template for your "All book pages" page. More info on templates here.

Example:

$posts = get_posts(array(
    "post_type"=>"book_pages",
    "post_status"=>"publish",
    "posts_per_page"=>-1 
));

if ($posts && count($posts)>0) 
{
    global $post;
    foreach ($posts as $post)
    {
        setup_postdata($post);
        the_title(); //prints out the title of this post
    }
    wp_reset_postdata(); 
}
