How to "fix" sorting by name in woocomerce?

Question

CMS

Made by this method: 365-progress.ru/tehnologii/web/svoya-sortirovka-to...
But, the problem is that our goods are numbered. And outputs it like this:

Товар №1
Товар №10
Товар №11
Товар №12
...
Товар №18
Товар №19
Товар №2
Товар №20
Товар №21
...
Товар №28
Товар №29
Товар №3
...

And it is necessary that it be 1 2 3 ..
Could you tell me where the sorting function itself is, or how to solve this problem?
If sorting is done immediately using an sql query, then how to edit it correctly?

Answer 1

The problem is that the names are sorted as strings, so in fact everything is correct) BUT you need to sort as numbers.
Hypothetically, this should work:

$args['meta_key'] => 'имя_мета_поля', 
$args['orderby'] => 'meta_value_num', 
$args['order'] => 'ASC'

Perhaps you need to start another field, where you drive in pure numbers.
