您可以通过在主题函数php文件中添加以下代码来实现这一点。

add_action( \'pre_get_posts\', \'iconic_hide_out_of_stock_products\' );

function iconic_hide_out_of_stock_products( $q ) {

if ( ! $q->is_main_query() || is_admin() ) {
    return;
}

if ( $outofstock_term = get_term_by( \'name\', \'outofstock\', \'product_visibility\' ) ) {

    $tax_query = (array) $q->get(\'tax_query\');

    $tax_query[] = array(
        \'taxonomy\' => \'product_visibility\',
        \'field\' => \'term_taxonomy_id\',
        \'terms\' => array( $outofstock_term->term_taxonomy_id ),
        \'operator\' => \'NOT IN\'
    );

    $q->set( \'tax_query\', $tax_query );

}

remove_action( \'pre_get_posts\', \'iconic_hide_out_of_stock_products\' );

}
