Editable phone number in header and footer, how?

Question

WordPress

Sorry again

Это уже 3 / 4 мой вопрос на WP за сегодня ... сорри ребят (зато за сегодня я апнулся больше чем за всю прошлую неделю)

Guys, if in the header (header.php) and in the footer (footer.php) the phone number is (the same). It's not a link, it's just wrapped in a span tag. How can I implement its editing through the admin panel?
Tried through the customizer ... did not work. It didn't work with the free ACF plugin either.

Answer 1

1. you can use wp custom fields and display them (you can do them in the admin panel on the Contacts page, and display them where necessary).
2. The same with ACF (simplicity and convenience)
3. Creating a custom page in wp to display settings
4. Using the same ACF, creating an options page https://www.advancedcustomfields.com/resources/opt...
and output on it all the fields that are needed for the site
I think for each custom field to create records is nonsense)

Answer 2

create a page where the title is the phone number and in the template you pull it by id

<?php
$my_id = 7;
$post_id_7 = get_post($my_id); 
$telefon = $post_id_7->post_title;
?>
