Reply To: Querying by Taxonomy field and separating by one such taxonomy

Figured it out. I needed to write a foreach for the specific taxonomy I wanted to separate the posts by, but also place the individual version of that foreach statement into the tax_query.

<?php

$domains  = 'math_domains';
$grades = 'math_grades';

$domainterms = get_field( 'matrix_domain' );
$gradeterms = get_field( 'matrix_grades' );

  if (!is_array($domainterms)) {
    $domainterms = array($domainterms);
  }
  if (!is_array($gradeterms)) {
    $gradeterms = array($gradeterms);
  }

$pagegrades = get_terms( 'math_grades' );

foreach( $pagegrades as $pagegrade ) : ?>

<?php
    $args = array(
        'post_type'      => 'math_matrix',
        'posts_per_page' => -1,
    'tax_query' => array(
      'relation' => 'AND',
      array(
        'taxonomy' => $domains,
        'field' => 'term_id',
        'terms' => $domainterms,
      ),
      array(
        'taxonomy' => $grades,
        'field' => 'term_id',
        'terms' => $pagegrade,
      ),
    ),
    );

    $posts = new WP_Query( $args ); ?>
<?php if( $posts->have_posts() ): ?> 
<h4><?php echo $pagegrade->name ;?></h4>
<div class="matrix-labels"><div class="standard-label">Standard</div><div class="can-label">Can the student:</div><div class="cannot-label">If not:</div><div class="resource-label">Additional Resource</div></div>
<ul class="matrix-search">
                    

            <?php while( $posts->have_posts() ) : $posts->the_post(); ?>
<li><div class="matrix-standard"><div class="mobile-label">Standard</div><?php global $post;
$standards = wp_get_post_terms($post->ID, 'math_standards', array("fields" => "names"));
if (count($standards) > 0)
{
    echo implode(', ', $standards);
}; ?></div>
       <div class="matrix-title"><div class="mobile-label">Title</div><?php the_title(); ?></div>
       <div class="matrix-action"><div class="mobile-label">Action</div><a>" target="_blank"><?php echo esc_html($actionsTitle); ?></a></div>
       <div class="matrix-resource"><div class="mobile-label">Additional Resource</div><a>" target="_blank"><?php echo esc_html($resourcesTitle); ?></a></div>
</li>
            <?php endwhile; endif; ?>

</ul>
<?php endforeach; ?>
