没有得到多条记录导致foreach

Question

我正在尝试获取每个对象的分数，最后我需要添加这些分数。

我正在使用 foreach 循环，但结果只得到一个对象点。

请帮我把所有物体的积分作为总和

        $pointType         = PointType::find($this->pointUser->point_type_id);



   //to get transaction details

假设产品 A 有 22 个 jpoints 和 33 个 bpoints，产品 b 有 10 个 jpoints 和 12 个 bpoints，我只得到 A 产品的点，但我需要输出作为产品 a 和产品 b 点的总和

我正在尝试获取每个对象点，最后我需要添加这些点。我正在使用 foreach 循环。但是我只得到一个对象点，因此请帮助我将所有对象点作为总和

Answer 1

如果我正确理解了您的问题，那么您只获得一种产品的结果的原因是因为您在循环中使用了return。相反，您可以定义一个名为 $totalPoints 之类的变量，添加到它，然后在循环之后返回该值，例如

$totalPoints = 0;

foreach ($trans_detail as $value) {

    //The rest of the code

    if ($points - floor($points) > 0.99) {
        $totalPoints += floor($points) + 1;
    } else {
        $totalPoints += floor($points);
    }

}

return $totalPoints;

此外，您不必使用它，但看起来您可以大大简化您的代码：

public function getTransactionPoint($transactionId)
{
    $pointType = PointType::find($this->pointUser->point_type_id);

    $trans_detail = DB::table('jocom_transaction_details AS a')
        ->select('a.*', 'b.*')
        ->leftJoin('jocom_products AS b', 'a.sku', '=', 'b.sku')
        ->where('a.transaction_id', '=', $transactionId)->get();

    $pointsName = $pointType->type == 'BCard' ? 'bpoints' : 'jpoints';

    $totalPoints = 0;

    $today = strtotime(date('Y-m-d'));

    foreach ($trans_detail as $value) {

        if ($today >= strtotime($value->valid_from) && $today <= strtotime($value->valid_to)) {
            $points = $value->multibpoints ? $value->multibpoints * $value->price : $value->$pointsName;
        } else {
            $points = ($value->price) * $pointType->earn_rate;
        }

        $totalPoints += $points - floor($points) > 0.99 ? floor($points) + 1 : floor($points);
    }

    return $totalPoints;
}
