如何使用 SQL 查询获得 woocommerce 最畅销的产品，包括产品图像等...？

Question

我需要在这里从 woocommerce 获得畅销产品

SELECT * FROM wp_posts  
INNER JOIN wp_postmeta 
ON ( wp_posts.ID = wp_postmeta.post_id ) WHERE 1=1 
AND ( wp_postmeta.meta_key = 'total_sales' ) 
AND wp_posts.post_type = 'product' 
AND (wp_posts.post_status = 'publish') 
GROUP BY wp_posts.ID 
ORDER BY wp_postmeta.meta_value+0 
DESC, wp_posts.post_date ASC LIMIT 0, 16

我尝试使用“SELECT TO”，但 mysql 不支持它也不支持“IN”！

Answer 1

这是我的解决方案：

 function best_selling_products(){
        global $wpdb;
// first of all I get IDs of the bestselling product with this query
        $query="SELECT wp_posts.id FROM wp_post

s INNER JOIN wp_postmeta 
ON ( wp_posts.ID = wp_postmeta.post_id ) 
WHERE 1=1 AND ( wp_postmeta.meta_key = 'total_sales' ) 
AND wp_posts.post_type = 'product' 
AND (wp_posts.post_status = 'publish') 
GROUP BY wp_posts.ID 
ORDER BY wp_postmeta.meta_value+0 DESC, wp_posts.post_date ASC LIMIT 0, 16";

//then i used that get whatever that I wand from wp_get_product with product id
    $prdtc=$wpdb->get_results($query);
    $array=array();
    $i=0;
foreach ($prdtc as $id)
 {
        $res = wc_get_product( $id->id);
                $array[$i]=array(
    $id->id,
    $res->get_name(),
    $res->get_price(),
    get_the_post_thumbnail_url($id->id),
    get_permalink($id->id)
);
            $i++;
        }
            echo json_encode($array,JSON_FORCE_OBJECT);
        }

这就是我希望它对某人有用的全部内容。

您可以使用此代码在循环中检索最畅销的产品。

<?php
    $args = array(
        'post_type' => 'product',
        'meta_key' => 'total_sales',
        'orderby' => 'meta_value_num',
        'posts_per_page' => -1,
    );
    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post(); 
    global $product; 
?>
<div>

<a href="<?php the_permalink(); ?>" id="id-<?php the_id(); ?>" title="<?php the_title(); ?>">

<?php 
if (has_post_thumbnail( $loop->post->ID )) 
echo get_the_post_thumbnail($loop->post->ID, 'shop_catalog'); 
else echo '<img src="'.woocommerce_placeholder_img_src().'" alt="product placeholder Image" width="65px" height="115px" />'; 
?>
<h3><?php the_title(); ?></h3>
</a>
</div>
<?php endwhile; ?>
<?php wp_reset_query(); ?>
