如何在yii2中添加最小计算

Question

1 .for example like this picture, I put in 30 kg of mass 2. result 123000, because 30 x 4100 = 123000 3. When entering 4 kg mass 4. the result is 123000 . because min mass 30 kg. even though 4 x 4100 = 16400. I want to be like that如何添加最小值计算。例如，质量为 1 千克的货物的价格 = 1000，最小质量为 100 千克的货物的价格 = 100000。所以当我想添加 45 千克或小于 100 千克时，结果仍然是 100,000，因为最小质量为 100公斤。如果我输入大于 100 的质量，例如 101，则 101 x 1000 = 101000。我只能指望此源代码，但没有最低使用量 100 公斤。谢谢

    'label' => 'Tarif',
    'format' => 'Currency',
    'value' => function ($model) {
        $volume = $model->rate * Yii::$app->request->get('TarifCargoSearch')['panjang'] * Yii::$app->request->get('TarifCargoSearch')['lebar'] * Yii::$app->request->get('TarifCargoSearch')['tinggi'] /4000 + $model->admin_fee;
        $mass = $model->rate * Yii::$app->request->get('TarifCargoSearch')['massa'];

        return $mass > $volume? $mass : $volume;
        }
    ],

我认为您必须将其解析为变量以便于使用

[
    'label' => 'Tarif',
    'format' => 'Currency',
    'value' => function ($model) {

        $panjang = Yii::$app->request->get('TarifCargoSearch')['panjang'];
        $lebar = Yii::$app->request->get('TarifCargoSearch')['lebar'];
        $tinggi = Yii::$app->request->get('TarifCargoSearch')['tinggi'];
        $volume = ($panjang * $lebar * $tinggi) / 4000;

        $rate = $model->rate;
        $rate_total = ($rate * $volume) + $model->admin_fee;

        $mass = Yii::$app->request->get('TarifCargoSearch')['massa'];
        $mass_min = 100;

        if ($mass_min < $mass) 
        {
           return $rate_total * $mass;
        } 
        else 
        {
           return $rate_total * $mass_min;
        }

     }
],
