This is standard WordPress functionality, contained in previous_post_link and next_post_link. You don’t need to edit functions.php. Just add to your template: <div class=”buttons”> <span class=”previous-button”><?php previous_post_link() ?></span> <span class=”next-button”><?php next_post_link() ?></span> </div> Now you can style the buttons with css. Follow the codex links for customizing options to the functions.
Here’s a good place to start: http://codex.wordpress.org/Template_Tags/previous_post_link http://codex.wordpress.org/Template_Tags/next_post_link As you will see, keeping the links to posts of the same category is as simple as setting an argument in the function. I would give an example but there are really good examples on the pages linked above.
Just put them between endwhile; and endif;
You could try the following plugin: http://wordpress.org/plugins/ambrosite-nextprevious-post-link-plus/ It is very customizable in terms of link options and should, as far as I can see, do the job for you. I have very good experience using it up to WP 3.5.
Maybe I don’t understand the question, sorry in that case. But can’t you just retrieve the last 6 posts excluding the current? Something like: global $post; $footer_posts = wp_get_recent_posts( array(‘post_status’ => ‘publish’, ‘posts_per_page’ => ‘6’, ‘exclude’ => $post->ID), 1 ); if ( ! empty($footer_posts) ) { foreach ( $footer_posts as $post ) { setup_postdata($post); echo … Read more
$prev = get_previous_post(); $next = get_next_post(); $prev_title = $prev ? get_the_title($prev) : ‘Current is First Post’; $next_title = $next ? get_the_title($next) : ‘Current is Last Post’; See get_previous_post and get_next_post on Codex for some details and additional params you can use.
Getting meta content from get_next_post & get_previous_post
I figured it out! After a lot of research and trial and error, I managed to figure out how to get the paging to work for both versions…my original code and the simplified code update. Original Code Solution: <?php $cat = get_cat_ID(“Photos”); $categories = get_categories(“child_of=$cat”); $limit = 9; $total = count($categories); $pages = ceil($total / … Read more
WordPress has a function called wp_get_referer() that you could use to do this. Codex link $page_referrer = wp_get_referer(); if ( $page_referrer == ‘campaign-1-url’) { // Campaign 1 css } You’ll have to craft the conditional statement to fit yours needs.
get_previous_post() and get_next_post() are deprecated. You should use get_previous_post_link() and get_next_post_link() or even better the wrapper functions the_post_navigation() or get_the_post_navigation(). If you don’t know how to use them, see the single.php template of the twentyfifteen theme that comes with WordPress by default. You can also see how these functions are implemented in the link-template.php file … Read more
