Good afternoon.
Now on WordPress linking structure is /%category%/%post_id%/ and the default length post_id 3 digits. How to do that would post_id was always 5 random numbers? That is, what would the URL of the article has always had kind of type www.site.com/category/12345. That is, to limit the minimal length of the slug. How to limit the maximum length found a lot of information. But the minimum is never mentioned.
UPD:
Hypothesis.
It is possible to do through wp_unique_post_slug()
here about it which in turn gives the variables using page slug
here is the code as I understand.
Accordingly, it is necessary to reassign this function via function.php by adding a new variable, for example post_random_slug, which is there to generate randomly (for example based on already existing function wp_generate_password(), one that generates passwords in WP, after adding it the filter by symbols, which would only the numbers were), and after to check whether there is such a slug, and if so, to conduct the re-generation, and if not, to return to wp_unique_post_slug () and in the "permanent links" to enter the structure site.ru/%category%/%post_random_slug%/ after will be added to this variable.
But unfortunately, my not a programmer. To write this cyberstacja I can't...
