我有两张桌子。一个用于订单和他们的偏好。表格如下所示:
订购:
+----------+---------------+------------+
| orderID | orderNumber | clientID |
+----------+---------------+------------+
| 1 | abc123 | 2 |
| 2 | orderX | 7 |
| 3 | Joe9 | 2 |
| 4 | Order4 | 2 |
+----------+---------------+------------+
订单偏好
+----------+----------+-------------+
| orderID | prefID | prefValue |
+----------+----------+-------------+
| 1 | 1 | $100 |
| 1 | 2 | 123 |
| 1 | 3 | $35 |
| 2 | 1 | $600 |
| 2 | 2 | 876 |
| 2 | 3 | $44 |
+----------+----------+-------------+
我想要的是对于每个订单,获取prefValue
特定的prefID
. 目前,这就是我正在做的事情:
$orders = OrdersQuery::create()->filterByClientID(2)->find();
foreach($orders as $o){
$prefs = $o->getOrderPrefs();
foreach($prefs as $p){
if($p->getPrefID() === 2){
echo $p->getPrefValue();
break;
}
}
}
这可行,但需要有一种更好的方法来为每个订单获取我想要的一行,而无需遍历所有首选项。
我知道这不起作用,但是有这样的东西吗?
$orders = OrdersQuery::create()->filterByClientID(2)->find();
foreach($orders as $o){
// This obviously doesn't work, so is there a short way to do this?
echo $o->getOrderPrefs()->filterByPrefID(2)->getPrefValue();
}
我正在阅读文档并找到了一种->search()
方法,但我不知道如何使用它。
$orders = OrdersQuery::create()->filterByClientID(2)->find();
foreach($orders as $o){
// How can I search for the row with the prefID I want?
echo $o->getOrderPrefs()->search()->getPrefValue();
}
