Question

我通过用户登录在其帐户页面中显示购买的产品。我使用此链接https://www.codesd.com/item/woocommerce-list-all-the-products-previously-ordered.html上的说明实施了该操作。我只想显示产品类型为“简单”的购买产品，而不显示所有购买的产品。

我使用以下查询：

global $wpdb;

$current_user   = wp_get_current_user();
$customer_email = $current_user->user_email;
$customer_data = array( $customer_email );
$statuses      = array_map( 'esc_sql', wc_get_is_paid_statuses() );

$result = $wpdb->get_col( "
    SELECT im.meta_value FROM {$wpdb->posts} AS p
    INNER JOIN {$wpdb->postmeta} AS pm ON p.ID = pm.post_id
    INNER JOIN {$wpdb->prefix}woocommerce_order_items AS i ON p.ID =  i.order_id
    INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS im ON i.order_item_id = im.order_item_id
    WHERE p.post_status IN ( 'wc-" . implode( "','wc-", $statuses ) . "' )
    AND pm.meta_key IN ( '_billing_email', '_customer_user' )
    AND im.meta_key IN ( '_product_id', '_variation_id' )
    AND im.meta_value != 0
    AND pm.meta_value IN ( '" . implode( "','", $customer_data ) . "' )
" );

要仅显示产品类型为“简单”的产品，将插入正确的sql查询是什么？

Answer 1

仅可以使用以下代码将此查询限制为简单产品，在该代码中，我们基于product_type Woocommerce分类法（管理产品类型）进行子“分类法查询” 词条simple （简单产品）：

global $wpdb;

$current_user   = wp_get_current_user();
$customer_email = $current_user->user_email;
$customer_data = array( $customer_email );
$statuses      = array_map( 'esc_sql', wc_get_is_paid_statuses() );

$result = $wpdb->get_col( "
    SELECT im.meta_value 
    FROM {$wpdb->posts} AS p
    INNER JOIN {$wpdb->postmeta} AS pm 
        ON p.ID = pm.post_id
    INNER JOIN {$wpdb->prefix}woocommerce_order_items AS i 
        ON p.ID =  i.order_id
    INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS im 
        ON i.order_item_id = im.order_item_id
    WHERE p.post_status IN ( 'wc-" . implode( "','wc-", $statuses ) . "' )
    AND pm.meta_key IN ( '_billing_email', '_customer_user' ) 
    AND im.meta_key = '_product_id'
    AND im.meta_value IN (
        SELECT tr.object_id 
        FROM {$wpdb->prefix}term_relationships as tr
        INNER JOIN {$wpdb->prefix}term_taxonomy as tt 
            ON tr.term_taxonomy_id = tt.term_taxonomy_id
        INNER JOIN {$wpdb->prefix}terms as t 
            ON tt.term_id = t.term_id
        WHERE tt.taxonomy = 'product_type' 
        AND t.slug = 'simple'
    )
    AND pm.meta_value IN ( '" . implode( "','", $customer_data ) . "' )
    GROUP BY im.meta_value
" );

// The raw output (testing
echo '<pre>'; print_r($result); echo '</pre>';

经过测试可以正常工作。
