A big post in wordpress divided into, say, five pages with the help of the <!--nextpage--> tag.
By default, the page numbers and links are displayed in the 'body' with the help of the "wp_link_pages()" or "link_pages()" code.
The 'title' displays, for example:
Blog-Name | Post-Name
What I need:
To display the page number in the title of the 'single.php' template.
Blog-Name | Post-Name | Page-number
However I tried, I cannot display the page number.
Various plugins can display page numbers only in the 'title' of 'index.php' or 'archive.php'
But in separage posts divided into pages the page number is not displayed
Please, give me some advice.
PS. Do not judge me strictly - I'm a novice.
