I solved it:
Just in case anybody ever has any trouble querying a post with the same term of a Taxonomy in another Post Type. I’ll post my answer below because I finally solved it on my own.
`<?php
$terms = get_the_terms( $post->ID, ‘supplier-tax’);
foreach ( $terms as $term ) {
$termID[] = $term->term_id;
}
$the_query = new WP_Query( array(
‘post_type’ => ‘supplier’,
‘tax_query’ => array(
‘taxonomy’ => ‘supplier-tax’,
‘field’ => ‘slug’,
‘terms’ => ‘$termID’,
),
) );
while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<p class=”supplier”>Supplied by <strong><?php the_title(); ?></strong></p>
<img src=”<?php the_field(‘logo’); ?>”>
<?php endwhile; ?>
<?php wp_reset_postdata(); ?>`
I hope this helps someone because this was hard to find a solution too.
