Wordpress: get all posts of a custom type

Question

I have this strange issue. I want to fetch all posts that are of a custom type, here's my snippet.

$query = new WP_Query(array(     'post_type' => 'custom',     'post_status' => 'publish' ));   while ($query->have_posts()) {     $query->the_post();     $post_id = get_the_ID();     echo $post_id;     echo "<br>"; }  wp_reset_query(); 

This only gets me 6 of them, while I have more than 50 records matching that criteria in the database. Can anyone tell me where I have gone wrong?

Many thanks!

Answer 1

'posts_per_page' => -1,

Add this to the WP_QUERY array of arguments and it should return all of the posts of this custom post type.

Answer 2

This get all posts of a custom type using get_posts:

$posts = get_posts([   'post_type' => 'custom',   'post_status' => 'publish',   'numberposts' => -1   // 'order'    => 'ASC' ]);
