如果在 woocommerce 中找到图像，则获取产品？

Question

我想在 woocommerce 中仅显示图片产品。

下面给出了我的获取查询

$args = array( 'post_type' => 'product', 'stock' => 1, 'posts_per_page' => 9, 'orderby' =>'date','orderby' => 'rand' );
$loop = new WP_Query( $args );

我怎样才能只获得图像产品？

Answer 1

你在寻找这样的东西吗？

<?php 
    $args = array( 'post_type' => 'product', 'stock' => 1, 'posts_per_page' => 9, 'orderby' =>'date','orderby' => 'rand' );
    $loop = new WP_Query( $args );
    while ($loop->have_posts()) : $loop->the_post();
        echo get_the_post_thumbnail($loop->post->ID, 'shop_catalog');
    endwhile;
?>

更新

$args = array( 
                'post_type' => 'product', 
                'stock' => 1, 
                'posts_per_page' => 9, 
                'orderby' =>'date',
                'orderby' => 'rand', 
                'meta_query'=>array(
                    array(
                        'key'=>'_thumbnail_id', 
                        'compare' => 'EXISTS'
                    )
                )
            );

如果产品有特征图像，则更改 arg 以获取产品。
