Question

我有以下代码，我试图获取订单列表。

所以从wcomm（woocommerce_order_itemmeta）表中，我只想显示meta_key等于_qty或_product_id的meta_value，我需要像我一样对单个值进行_product_id过滤。我似乎无法做到这两件事。我的输出永远不会显示_qty值，因为我特意过滤了_product_id的值，但我不明白要改变什么

global $wpdb;
$wpdb->woocommerce_order_items = $wpdb->prefix . 'woocommerce_order_items';
$wpdb->woocommerce_order_itemmeta = $wpdb->prefix . 'woocommerce_order_itemmeta';

$uvuorderposts = $wpdb->get_results( 
    "
    SELECT p.ID, p.post_title, p.post_date, wcom.order_item_name, wcomm.meta_key, wcomm.meta_value
    FROM $wpdb->posts AS p
    INNER JOIN $wpdb->postmeta AS pm ON p.ID = pm.post_id
    INNER JOIN $wpdb->woocommerce_order_items AS wcom ON p.ID = wcom.order_id
    INNER JOIN $wpdb->woocommerce_order_itemmeta AS wcomm ON wcom.order_item_id = wcomm.order_item_id
    WHERE (p.post_type = 'shop_order')
    AND (pm.meta_key = '_wc_authorize_net_aim_charge_captured')
    AND (pm.meta_value = 'yes')
    AND (wcomm.meta_key = '_product_id')
    OR (wcomm.meta_key = '_qty')
    AND (wcomm.meta_value = '2193')
    ORDER BY p.post_date
    "
);

echo "<table>";
foreach ( $uvuorderposts as $uvuorderpost ) 
{
    echo "<tr><td>" . $uvuorderpost->post_title . " - " . $uvuorderpost->ID . "</td><td>" . $uvuorderpost->post_date . "</td><td>" . $uvuorderpost->meta_key . ": " .  $uvuorderpost->meta_value . "</td></tr>";
    echo "<tr bgcolor='#eaeaea'><td colspan='3'>" . $uvuorderpost->order_item_name . "</td></tr>";
}
echo "</table>";

我试图＆＃34;过滤＆＃34;它在输出上使用$ uvuorderpost-＆gt; meta_key [＆＃39; _qty＆＃39;]但它不起作用！

我通过以下更改修复了它。刚加入那张桌子两次，现在就可以了。不确定这是不是最好的做法，但是是的

global $wpdb;
$wpdb->woocommerce_order_items = $wpdb->prefix . 'woocommerce_order_items';
$wpdb->woocommerce_order_itemmeta = $wpdb->prefix . 'woocommerce_order_itemmeta';

$uvuorderposts = $wpdb->get_results( 
    "
    SELECT p.ID, p.post_title, p.post_date, wcom.order_item_name, wcomm.meta_key, wcomm.meta_value, wcomm2.meta_key AS meta_key_qty, wcomm2.meta_value AS meta_value_qty
    FROM $wpdb->posts AS p
    INNER JOIN $wpdb->postmeta AS pm ON p.ID = pm.post_id
    INNER JOIN $wpdb->woocommerce_order_items AS wcom ON p.ID = wcom.order_id
    INNER JOIN $wpdb->woocommerce_order_itemmeta AS wcomm ON wcom.order_item_id = wcomm.order_item_id
    INNER JOIN $wpdb->woocommerce_order_itemmeta AS wcomm2 ON wcom.order_item_id = wcomm2.order_item_id
    WHERE (p.post_type = 'shop_order')
    AND (pm.meta_key = '_wc_authorize_net_aim_charge_captured')
    AND (pm.meta_value = 'yes')
    AND (wcomm.meta_key = '_product_id')
    AND (wcomm.meta_value = '2193')
    AND (wcomm2.meta_key = '_qty')
    ORDER BY p.post_date
    "
);

echo "<table>";
foreach ( $uvuorderposts as $uvuorderpost ) 
{
    echo "<tr><td>" . $uvuorderpost->post_title . " - " . $uvuorderpost->ID . "</td><td>" . $uvuorderpost->post_date . "</td></tr>";
    echo "<tr bgcolor='#eaeaea'><td colspan='2'>" . $uvuorderpost->order_item_name . "</td></tr>";
    echo "<tr bgcolor='#eaeaea'><td colspan='2'>" . $uvuorderpost->meta_key . " : " .  $uvuorderpost->meta_value . "</td></tr>";
    echo "<tr bgcolor='#eaeaea'><td colspan='2'>" . $uvuorderpost->meta_key_qty . " : " .  $uvuorderpost->meta_value_qty . "</td></tr>";        
}
echo "</table>";

wpdb选择查询以获取某些meta_key？
