How to make city subdomains and meta tags through shortcodes for each city in wordpress?

Question

Search Engine Optimization

Hello everyone,
there is a site for WordPress services, you need to create city subdomains, and for them meta tags (title and description) that will differ only by city.
Here is an example of a meta tag: I provide a "shortcode" service, where the shortcode is, for example, "in Moscow" and each subdomain will have its own city shortcode.
I know that there is a plugin in Bitrix that allows you to display cities in meta tags and site content on subdomains through shortcodes. Those. I assign the city to the subdomain links of the gorod.site.ru type in the plugin, and for the city the shortcode in the required case, then I add the shortcode to the meta tag and it changes the city subdomain depending on the subdomain.
The content on subdomains should match 100% with the content on the main site, only the title, description, Yandex Map for a specific city with the office tag should differ, and cities should be added to h1 titles. How can this be implemented?

Answer 1

You can influence the formation of meta tags through functions.
Auto Generate Meta Description Meta Description from The_content
Pasting this code snippet into your WordPress theme's functions.php file will automatically generate a meta description from your post, stripping out shortcodes and tags. Also make sure you have this code in your header.php file otherwise this snippet won't work.

function create_meta_desc() {
    global $post;
    if (!is_single()) { return; }
    $meta = strip_tags($post->post_content);
    $meta = strip_shortcodes($post->post_content);
    $meta = str_replace(array("n", "r", "t"), ' ', $meta);
    $meta = substr($meta, 0, 125);
    echo "<meta name='description' content='$meta' />";
}
add_action('wp_head', 'create_meta_desc');

But instead of $post, get your array of data from where you will take the list of cities.
Then around

echo "<meta name='description' content='$meta' />";

wrap it in text

echo "<meta name='description' content=' \"текст до города\" . $meta . ' /> " . \"текст после города\";

Answer 2

Create a subdomain and set up yaost, the principle is similar to Bitrix with shortcodes

Answer 3

Do you want to make a city template, then spread this template across subdomains, and depending on the subdomain, it will change the value of the short code?
You need to do 2 things:
1) Compose city shortcodes in different cases
for meta tags, it is better to use do_action instead of shortcodes
2) Check your subdomain, and if it is such and such, then display such and such a city.
<?php echo $_SERVER['SERVER_NAME']; ?>
