如何根据 category_id 使用 mysql -php 检索 woocommerce 产品详细信息

Question

我必须从 woocommerce table.

检索产品详细信息，例如图片标题、描述、图片 link 和价格

我已经使用此查询检索了类别，

$result = mysql_query("SELECT term_id,name,slug FROM wp_terms WHERE term_id 
    IN (SELECT term_id FROM wp_term_taxonomy WHERE parent='0' 
    AND taxonomy='product_cat') ORDER BY name ASC");

基于这个类别 ID，我正在检索这样的子类别：

  $result = mysql_query("SELECT term_id,name,slug FROM wp_terms WHERE term_id
     IN (SELECT term_id FROM wp_term_taxonomy WHERE parent='$cat_id'
     AND taxonomy='product_cat') ORDER BY name ASC");

我已尝试通过查询获取产品详细信息，

 $result = mysql_query("SELECT  `ID`,`post_title`,`post_content`,`guid` FROM wp_posts WHERE
post_type='product' and post_status='publish' and ID IN(SELECT object_id
FROM wp_term_relationships WHERE term_taxonomy_id IN('$cat_id') and 
term_taxonomy_id IN(SELECT term_taxonomy_id FROM wp_term_taxonomy 
where taxonomy='product_cat'))");

当我在 phpmyadmin 中执行它时，这给了我标题和描述，但是当我在 php 中给出相同的代码并通过 json 发送响应时，它给出了我空洞的回应。

我觉得我的查询不妥。

请建议我如何从 woocommerce 获取产品详细信息，我是第一次使用它。

Answer 1

听起来您可以为此使用标准 WP_Query():

$args = array( 
    'post_type' => 'product', 
    'posts_per_page' => -1, 
    'product_cat' => $cat_id, 
);
$result = new WP_Query( $args );

Answer 2

我终于搞定了

步骤如下：

    --->  get `id` of product from `wp_posts`
    --->  pass it as a `post_id` to `wp_postmeta` and get the `meta_value` where `meta_key`='_thumbnail_id'
    --->  now send this `meta_value` as `id` of the product to `wp_posts `
    --->  in the field `guid` we have the link of image of the product

获取产品价格：

---> Send `id` as a `post_id` to `wp_postmeta` and get the `meta_value` where `meta_key`='_price'

Product description和product title分别存储在tablewp_posts字段post_title和post_excerpt中。

我已经分别执行了所有这些查询。这就是为什么我不在这个 answer.I 中添加它们的原因joins

完成后将编辑此答案

编码愉快..:)

Answer 3

试试这个，

global $wpdb;
$products = $wpdb->get_results("SELECT *
                                FROM wp_posts
                                LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id)
                                LEFT JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id)
                                 WHERE wp_term_taxonomy.term_id = 60
                                 ROUP BY wp_posts.post_title");

您必须根据您的类别编号更改 WHERE wp_term_taxonomy.term_id = 60，例如 WHERE wp_term_taxonomy.term_id = $cat_no 或类似的内容。
