I'm having some issues with previous_post_link() and next_post_link()

Question

I've been developing a Wordpress site lately and have come across an issue. I need the user to be able to navigate between posts, I'm using the standard Wordpress functions previous_post_link() and next_post_link() which should in THEORY output the links to the next and previous posts in the database... BUT the only links that appear are in the case of the latest post; the first post that was published and in the case of the first post that was published; the latest post.

There are 5 posts and they all produce the same links, I'm not doing anything silly or outside of the box.

I also had some initial issues with pagination on the main blog feed but that appears to be fixed now....

Here is my code:

single.php

<?php get_header(); the_post();?>

    <div class="page-heading--cloud">
        <h1>BLOG</h1>
    </div>

    <article class="single">
        <div class="single__wrap">
            <img class="single__image" src="<?php echo Image::get(wp_get_attachment_url(get_post_thumbnail_id($post->ID))); ?>">
            <p class="single__date">Posted on <?php the_time('jS F Y'); ?> by <?php the_author(); ?></p>
            <h1 class="single__title"><?php the_title(); ?></h1>
            <div class="single__content">
                <?php the_content(); ?>
            </div>
        </div>
    </article>

    <div class="page-navigation">
        <hr class="page-navigation__line">
        <p class="page-navigation__link"><?php previous_post_link('<i class="fa fa-long-arrow-left"></i> %link'); ?></p>
        <p class="page-navigation__link"><?php next_post_link('%link <i class="fa fa-long-arrow-right"></i>'); ?></p>
        <hr class="page-navigation__line">
    </div>

<?php get_footer();?>

and here is the main blog feed:

index.php

<?php get_header(); ?>

    <!-- Side info -->
    <div class="page-heading--cloud">
        <h1>BLOG</h1>
    </div>

    <div class="blog page-data">
        <article class="page-data__main">
            <?php while(have_posts()) : the_post(); ?>
                <div class="blog__post">
                    <img class="blog__image" src="<?php echo Image::get(wp_get_attachment_url(get_post_thumbnail_id($post->ID))); ?>">
                    <div class="blog__post__wrap">
                        <p class="blog__post__date">Posted on <?php the_time('jS F Y'); ?> by <?php the_author(); ?></p>
                        <h2 class="blog__post__title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
                        <p class="blog__post__excerpt"><?php echo get_the_content_excerpt(30); ?></p>
                        <a class="blog__post__more" href="<?php the_permalink(); ?>">Continue Reading <i class="fa fa-arrow-right"></i></a>
                    </div>
                </div>
            <?php endwhile;?>

            <?php if(!have_posts()) : ?>
                <h2>There are no posts to display at this time.</h2>
            <?php endif; ?>

        </article>

        <?php get_template_part('partials/sidebar', 'landing'); ?>
    </div>

    <div class="page-navigation">
        <hr class="page-navigation__line">
        <p class="page-navigation__link"><?php previous_posts_link('<i class="fa fa-long-arrow-left"></i> Newer Posts'); ?></p>
        <p class="page-navigation__link"><?php next_posts_link('Older Posts <i class="fa fa-long-arrow-right"></i>'); ?></p>
        <hr class="page-navigation__line">
    </div>
<?php get_footer(); ?>

I hope that someone is able help me with this issue, if you're able to direct me to potential fixes that would be great! Though I have already searched and searched, tried peoples suggestions etc which is why I've chosen to make this post.

If something isn't clear please let me know :)

Thanks in advance!

Answer 1

I've realised what the issue was... some of my posts were generated (for development purposes) using bulk creator which appears to not create a complete post! When I create a post manually using the WP backend my code works fine, thanks for the suggestions anyway guys!
