Exclude a WooCommerce product category from a WP_Query

问题

I've got the following args defined as a part of my query:

$args = apply_filters('woocommerce_related_products_args', array(
        'post_type'             => 'product',
        'author'                => $artist,
        'post_status'           => 'publish',
        'meta_query'            => array(
            array(
                'key'           => '_visibility',
                'value'         => array('catalog', 'visible'),
                'compare'       => 'IN'
        )
    )
) );
$products = new WP_Query( $args );

I need to exclude a category called Magazines (slug "magazines") or ID 351 from the query.

I've been trying to include 'category__not_in' => array('magazines'), so it looks like this:

$args = apply_filters('woocommerce_related_products_args', array(
            'post_type'             => 'product',
            'author'                => $artist,
            'post_status'           => 'publish',
            'category__not_in'      => array('magazines'),
            'meta_query'            => array(
                array(
                    'key'           => '_visibility',
                    'value'         => array('catalog', 'visible'),
                    'compare'       => 'IN'
            )
        )
    ) );
    $products = new WP_Query( $args );

But that just doesn't seem to be working.

What am I doing wrong here?

Product categories are a custom taxonomy product_cat.

So you need to do it in a simple tax_query this way:

$args = apply_filters('woocommerce_related_products_args', 
    array(
        'post_type'             => 'product',
        'author'                => $artist,
        'post_status'           => 'publish',
        'meta_query'            => array(
             array(
                'key'           => '_visibility',
                'value'         => array('catalog', 'visible'),
                'compare'       => 'IN'
            ),
        ),
        'tax_query'            => array(
            array(
                'taxonomy' => 'product_cat',
                'field'    => 'slug', // Or 'name' or 'term_id'
                'terms'    => array('magazines'),
                'operator' => 'NOT IN', // Excluded
            )
        )
    ) 
);

$products = new WP_Query( $args );

You should use category__not_in value as an array like this

$query = new WP_Query( array( 'category__not_in' => array( 'magazines' ) ) );

For details check this

WP_Query

So please update your code into this

$args = apply_filters('woocommerce_related_products_args', array(
            'post_type'             => 'product',
            'author'                => $artist,
            'post_status'           => 'publish',
            'category__not_in'      => array('magazines')
            'meta_query'            => array(
                array(
                    'key'           => '_visibility',
                    'value'         => array('catalog', 'visible'),
                    'compare'       => 'IN'
            )
        )
    ) );
    $products = new WP_Query( $args );

Let me know whether its working or not for you.
