WP_Query returns nothing

    My second stumper of the day.

    On my single.php template, I’m displaying the usual content and several fields created with Advanced Custom Fields. All of that data displays correctly, but when I try to show related posts from the same category, I get nothing, even though I know 2-3 related posts exist in that category.

    I’ve done this type of related posts query on several sites, as have billions of other developers. But I don’t completely understand when I do and don’t need to reset the post data and feel like that may be the issue.

    Any obvious issues with this query?

    <?php  
// related stories category info passed in from single.php or template-cat-landing.php
// $category_name is defined at the top of the page

$currentID = get_the_ID();

$args = array( 
  'category_name' =>  $category_name,
  'orderby' => 'date',
  'post_type'=> 'post',
  'posts_per_page' => -1,
  'post__not_in' => array($currentID),

);

$the_query = new WP_Query( $args );
// The Loop

//if ( $the_query->have_posts() ) : ?>

    <section id="all-stories" class="layer">
        <div class="control-wrapper">
            <div class="row">
                <div class="col-xs-12">

    I found a solution.

    Instead of using the category name, I used the category ID. I’m not sure why can cannot rely solely on the category name, but ID worked for me.

    Here is the revised code:

    <?php  
// related stories category info passed in from single.php or template-cat-landing.php

$currentID = get_the_ID();
$category_id = get_cat_ID( $category_name );

$args = array( 
  'cat' => $category_id,
  'orderby' => 'date',
  'post_type'=> 'post',
  'posts_per_page' => -1,
  'post__not_in' => array($currentID),
);

$the_query = new WP_Query( $args );

// The Loop

//if ( $the_query->have_posts() ) : ?>

    <section id="all-stories" class="layer">
        <div class="control-wrapper">
            <div class="row">
                <div class="col-xs-12">
                    <div class="row">
                        <div class="col-xs-12">
                            <h2 class="h3 tapered-lines special-text pad-bottom">
                                Browse All of Our <?php echo $category_name; ?> Stories 
                            </h2>
                        </div>
                    </div>
                    <div class="row">
                        <div class="col-xs-12">
                            <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
                            
                                    <div class="story-card-wrap">
                                        <div class="story-card">
                                            <a href="<?php echo get_permalink( $post->ID ); ?>"><?php echo get_the_post_thumbnail( $post->ID, 'thumbnail' ); ?>       
                                                <div class="info">
                                                    <div class="content-label"><?php echo $category_name; ?></div>
                                                    <h3><?php the_title(); ?></h3>
                                                </div>

                                    </div><!-- /story-card-wrap -->

                            <?php endwhile;  ?>
                            
                        </div>
                        
                    </div>
                    
                </div>
            </div>
        </div><!-- end control-wrapper -->
