How to give paged links custom title?

I have split my post content into mutiple pages using the <! - nextpage -> code. I want to give my paginated links their own title instead of the regular 1,2,3. How can I do this? cause on this doc https://codex.wordpress.org/Styling_Page-Links it only mentions method to adding suffix or prefix. I just want to give each paged number their own custom title

WordPress Enqueue Script Chaos (jQuery & Foundation.js)

I’ve been working on building a theme for the past couple days now, and I’ve run into a wall. While I originally included foundation.js as an enqueued script, I couldn’t remember why I had added it.

How to add an export function to a custom Option Theme Page

I’m creating a new WordPress template and I have a question:
I’ve added a custom Option Page to my new template (you can see what I’m doing Here and Here) but now I would like to add a new function.
Do you know Si Contact Form? In this plugin the end user can download a backup of all the settings and Upload it on a different website.
I would like to be able to add the same function into my new option page.
I know how to backup my settings logging to phpMyAdmin but sometimes end-user can’t login to phpMyAdmin or simply it’s better that he/she doesn’t login to phpMyAdmin :-).
Have you got any solution to this?
Actually all my custom functions are named:
‘appaqua__zona1c’;’appaqua__zona1x’ and so on… my theme shortname is appaqua.
Please by kind with me, I’m not a professional programmer and I’m really sorry if I used wrong words to explain what I need.
Thank you very much to all!
