So I looked a bit closer at your code, and mine, there were other errors in both. I think this might do what you’re looking for.
<!-- Nav Tabs -->
<ul class="nav nav-pills">
<?php
if (have_rows('home_categories')) {
$i = 0;
while (have_rows('home_categories')) {
the_row();
$term = get_sub_field('categories');
?>
<li class="<?php
if ($i == 0) {
echo 'active';
}
?>"><a href="#<?php
echo $term->name; ?>" data-toggle="tab"><?php
echo $term->name; ?></a>
</li>
<?php
$i++;
}
}
?>
</ul>
<?php
// if your not getting anything below try reset_rows()
// uncomment the next line
//reset_rows();
?>
<!-- Tab Content -->
<div class="tab-content clearfix">
<?php
if (have_rows('home_categories')) {
$i = 0;
while (have_rows('home_categories')) {
the_row();
// moved this line up before query that uses it
$term = get_sub_field('categories');
$args = array(
'post_type' => 'post',
'tax_query' => array(
array(
'taxonomy' => $term->taxonomy,
// corrected terms to use correct value
'terms' => array($term->term_id)
)
),
'posts_per_page' => 5,
'orderby' => 'date',
'order' => 'ASC',
);
// if your still not getting anything
// uncomment and make sure the query args look right
//echo '<pre>'; print_r($args); echo '</pre>';
// renamed query to not use global $post variable
$query = new WP_Query($args);
while ($query->have_posts()) {
$query->the_post();
?>
<div class="tab-pane fade<?php
if ($i == 0) {
echo ' active';
}
?>" id="<?php echo $term->name; ?>">
<?php
the_post_thumbnail('thumbnail', array('class' => 'img-responsive img-thumbnail'));
?>
<h3><?php the_title(); ?></h3>
<?php the_excerpt(); ?>
</div>
<?php
} // end while have posts
$i++;
} // end while have rows
wp_reset_postdata();
} // end if have rows
?>
</div>
