仅当父产品已发布时如何获取产品变体

Question

我进行了自定义查询以获取产品变体，但是当我丢弃某个产品时，它的变体状态将保持 publish，因此如果客户尝试这样做，它会响应 404 错误查看废弃的产品变体。那么，如何过滤这些变体以仅获取已发布父产品的变体？

我的代码：

<?php  
$args = ['post_type'  => ['product_variation'],  
            'orderby'    => 'meta_value_num',
            'order'      => 'DESC',
            'post_status'=>'publish',
            'product_type'=>'variation',
            'meta_query' => [
                [
                    'key'     => 'attribute_pa_flower-type',
                    'value'   => $flower_type,
                    'compare' => '=',
                ]
            ]
        ];
?>

<?php $the_query = new WP_Query( $args );?>

<?php if ( $the_query->have_posts() ) : ?>

    <div class="boxes">
        <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        ...

做这样的事情：

//to hold the published product id which has vriation.
$has_variable_ids = [];

$args_parent = [
    'post_type' => ['product'],
    'post_status' => 'publish',
    'posts_per_page' => -1
];

$pubished_post = new WP_Query($args_parent);
if (!empty($pubished_post->posts))
{
    foreach ($pubished_post->posts as $post)
    {
        $_product = wc_get_product($post->ID);
        if ($_product->is_type('variable'))
        {
            // Product has variations
            $has_variable_ids[] = $post->ID;
        }
    }
}


$args = [
    'post_type' => ['product_variation'],
    'orderby' => 'meta_value_num',
    'order' => 'DESC',
    'post_status' => 'publish',
    'post_parent__in' => $has_variable_ids,
    'meta_query' => [
        [
            'key' => 'attribute_pa_flower-type',
            'value' => $flower_type,
            'compare' => '=',
        ]
    ]
];

$the_query = new WP_Query($args);

请注意：我还没有测试过，但应该可以。

希望对您有所帮助！
