Hi! I’m currently running WordPress 4.7.2, Version 4.6.4 of X Theme. http://froglation.xyz

Is there a way to limit the posts navigation to the posts in each category?

I currently have this code added to my function.php file.

add_action ('the_content', 'add_next_post_item_link' );

function add_next_post_item_link ( $content ) {
	if ( is_singular('post') ) {
		$next_name = "<- Previous Chapter <i class=\"x-icon-chevron-right\"></i>";
		$prev_name = "<i class=\"x-icon-chevron-left\"></i> Next Chapter -> ";
		$next_link = get_next_post() ? '<a style="float: right;" href="' . get_permalink( get_next_post()->ID ) . '">' . $prev_name . '</a>' : '';
		$prev_link = get_previous_post() ? '<a style="float: left;" href="' . get_permalink( get_previous_post()->ID ) . '">' . $next_name . '</a>' : '';
		$posts = '<div class="wp-post-navigation-next">'.$next_link.$prev_link.'</div>';
		return  $posts . $content . $posts;
	} else {
		return $content;
	}
}

Please advice on the modifications required.

Thanks!

Hello There,

Thanks for writing in! You can update it and make use of this code:

add_action ('the_content', 'add_next_post_item_link' );

function add_next_post_item_link ( $content ) {
	if ( is_singular('post') ) {
		$next_name = "<- Previous Chapter <i class=\"x-icon-chevron-right\"></i>";
		$prev_name = "<i class=\"x-icon-chevron-left\"></i> Next Chapter -> ";
		$next_link = get_next_post(true, '', 'category') ? '<a style="float: right;" href="' . get_permalink( get_next_post()->ID ) . '">' . $prev_name . '</a>' : '';
		$prev_link = get_previous_post(true, '', 'category') ? '<a style="float: left;" href="' . get_permalink( get_previous_post()->ID ) . '">' . $next_name . '</a>' : '';
		$posts = '<div class="wp-post-navigation-next">'.$next_link.$prev_link.'</div>';
		return  $posts . $content . $posts;
	} else {
		return $content;
	}
}
