How to sort the output of posts by a custom field in Wordpress?

Question

CMS

There is a site nashe-mesto.com/projects/?type=hitech-modern
I want to display records on this page in descending order of area. To do this, for this type of records, an arbitrary order_field field was created and sorting seems to be specified in the template. But it doesn't want to sort :(
Here is a piece of code from the template file of this page:
<?php get_header(); ?>
<?php
global $wp_query;
$ppr = 6;
$paged = ($wp_query->query_vars['paged']
) ?
_
_
_
_ -$ppr,
'orderby' => 'meta_value_num',
'meta_key' => 'order_field'
)
Unfortunately, I'm not good at this myself...

Answer 1

Perhaps the problem is exactly what values ​​are stored in an arbitrary field. Try to enter whole numbers in several posts, for example: 10, 20, 30 and see if it works. In a piece of code, everything seems to be as it should be.
