Next Page, Not Next Post is a very simple plugin that creates navigation between sibling pages.
This plugin gives you two new functions, <code>next_page_not_post($anchor_text, $loop, $sort)</code> & <code>previous_page_not_post($anchor_text, $loop, $sort)</code>. Each function has three simple options.
<ol>
<li>Anchor Text – Either set the anchor text manually or use the page title. Use %title to use page title with other strings. Defaults to page title, just leave blank for that.</li>
<li>Looping – Link the first element to the last and the last to the first, or not. Defaults to not looping. Set to true for looping, cousins for cousin based navigation and cousinsloop for cousins navigation that loops.</li>
<li>Get Pages – This is used to determine how to sort your results. Use the documentation at <a href="https://codex.wordpress.org/Function_Reference/get_pages" rel="nofollow ugc">Get Pages</a> to find all available options here. Defaults to menu_order ascending.</li>
</ol>
SHORTCODES You can use [next_page] and [previous_page] shortcodes within your page content. Supported options are ‘anchor’, ‘loop’ and ‘getPagesQuery’.

Next Page, Not Next Post

Have been looking for something like this for ages.

Ignore the out of date notice on the Wordpress website, this plugin is excellent if you want next previous links for Pages (and not posts).

The loop parameter even offers a 'cousins' feature which allows the next/prev links to traverse child pages with the same grandparent!



Excellent plugin

Easily create navigation to sibling pages. Similar to next_post_link() and previous_post_link() but for pages.
