how does get_term_by know which term to return when the same term appears twice in a hierarchical taxonomy?
get_term_by() just returns the first matching term, ‘first’ meaning some internal order in MySQL. If having multiple terms with the same name matters in your case, don’t rely on get_term_by() alone.
Get Current Custom Taxonomy ID by Post ID
(Probably better to use get_the_terms). $terms = wp_get_object_terms( $pid, ‘custom_category’, array(‘fields’=>’ids’)); Get an array of term ids (will always been array, even if it is an array of one): $ids = wp_list_pluck( $terms, ‘term_id’ ); If you just want one id… then ‘pop’ out the last id: $id = array_pop($ids); See also PHP docs on … Read more
get_term_children doesn’t return an array of children terms
At first, try passing the Taxonomy as a string: $children = get_term_children($term->term_id, ‘locations’); The function get_category_children produces a string as return, so you can just echo it. the function get_term_children, however, returns an array. To see the contents of the array, try print_r( $children ); instead of echo. The last thing to keep in mind … Read more

How do I Use Multiple Loops with WP_Query?
As Toscho mentionned above, you didn’t close your if and while. When in doubt, indent your codes to avoid confusion. $my_query = new WP_Query( $args ); if ($my_query->have_posts()) : while($my_query->have_posts()) : $my_query->the_post(); endwhile; endif; wp_reset_postdata(); /* The 2nd Query (without global var) */ $query2 = new WP_Query( $args2 ); // The 2nd Loop if ($query2->have_posts()) … Read more
