Hide out of stock products only on shop archive pages in Woocommerce

Question

I am trying to hide out of stock products only from Shop page, but keep them on the separate category page.

Woocommerce settings allows only to choose either to show

Answer 1

Updated: Using a custom function hooked in woocommerce_product_query_meta_query filter hook, targeting non "out of stock" products on shop archive pages only:

add_filter( 'woocommerce_product_query_meta_query', 'shop_only_instock_products', 10, 2 );
function shop_only_instock_products( $meta_query, $query ) {
    // Only on shop archive pages
    if( is_admin() || is_search() || ! is_shop() ) return $meta_query;

    $meta_query[] = array(
        'key'     => '_stock_status',
        'value'   => 'outofstock',
        'compare' => '!='
    );
    return $meta_query;
}

This code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested and works
