WP_Query Woocommerce products that belong in distinct multiple categories only tax_query

Question

I\'m using WP_Query for Woocommerce products in attempt to query products in a particular category. This is the syntax that worked for me -

$args =         


        

Answer 1

Inside a 'tax_query' array's array you can specify an 'operator' to be performed on the query. You can achieve what you want using the 'AND' operator.

$args = array(
'posts_per_page' => -1,
'tax_query' => array(
    'relation' => 'AND',
    array(
        'taxonomy' => 'product_cat',
        'field' => 'slug',
        'terms' => array( 'category-slug1', 'category-slug2' )
        'operator => 'AND',
    ),
),
'post_type' => 'product',
'orderby' => 'title',
);
$the_query = new WP_Query( $args );

All of the products selected by this query will match the provided 'terms'. See this link for more info: https://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters

In case the link ever breaks, here's the relevant info:

operator (string) - Operator to test. Possible values are 'IN', 'NOT IN', 'AND', 'EXISTS' and 'NOT EXISTS'. Default value is 'IN'.
