Parameters query_posts

Question

I use the following code to display posts from custom post type

query_posts( array( 'post_type' => 'success-stories', 'paged' => $paged, 'posts_per_page' => -1, 'meta_key' => 'post_id', 'orderby' => 'meta_value_num', 'order' => 'ASC' ) );

An arbitrary post_id field is set in order to be able to manually sort the posts (in the required order). But it is also necessary that the posts for which this parameter is not specified are displayed. Tell me, what needs to be changed in the request parameters?

using query_posts not safe.

Use get_posts , pre_get_posts or WP_Query .

https://codex.wordpress.org/Function_Reference/get_posts
https://developer.wordpress.org/reference/hooks/pre_get_posts/
https://codex.wordpress.org/Class_Reference/WP_Query

'meta_key' => 'post_id'

The names cannot use "post_id". This is a reserved term.

this is the name of the global variable codex.wordpress.org/Function_Reference/add_post_meta In general, a bad coding tone is to give your entities names used.
You must immediately get used to at least write your unique prefixes / suffixes.
This is the name of the local variable (argument) of the specified function, nothing more.
The list of global variables codex.wordpress.org/Global_Variables $post_id also missing.
Actually, the confirmation is that my test test.kagg.eu/so635358 is working.
And about the fact that the name post_id is not very good in their arbitrary fields to indicate - I agree.

The request should be done by OR , choosing both those posts where post_id not defined, or those where it is greater than zero:

 $args = array( 'post_type' => 'success-stories', 'paged' => $paged, 'posts_per_page' => -1, 'meta_query' => array( 'relation' => 'OR', array( 'key' => 'post_id', 'compare' => 'NOT EXISTS', 'value' => '' ), array( 'key' => 'post_id', 'compare' => '>', 'value' => '0' ) ), 'orderby' => 'meta_value_num', 'order' => 'ASC' ); query_posts($args);

In this case, displays all posts, except those where post_id is filled

Parameters query_posts
