Question

我查询从表productbatch获取mrp * rate直到小数点后2位。我已尝试过以下查询Productbatch::find()->select('mrp, rate, round((mrp*rate),2) as rateval')->asArray()->one();

当我只使用mrp * rate时，它给出了结果，但是小数点后有6或7位数。请让我知道如何将结果最多得到2位小数。

例如

如果我不使用round，如果mrp = 32且rate = 24.64，则mrp*rate的结果为 - 788.47998046875 .. 如果我使用代码中显示的Round，它就不会给出结果。我想要的是 - 788.48。

Productbatch Model

    //         'output' => $out,
    //         'selected' => ''
    //     ];
    // }
}

控制器操作 -

public function actionGetForItemid($prodname , $batchno)
    {
        $item = Productbatch::find()->joinWith(['productname0'])->joinWith(['productname0', 'productname0.hsncode'])->select('max(itemid) as itemid, expdate, mrp,rate, productname, batchno, round(rate*mrp,2) as rateval')->where(['productname'=>$prodname])->andWhere(['batchno'=>$batchno])->asArray()->one();
        echo Json::encode($item);
    }

调用控制器操作的Javascript -

<?php
/* start getting the itemid */
$script = <<< JS
function getItemID(item) {
    var index  = item.attr("id").replace(/[^0-9.]/g, "");
    var batch = product = 0;
    var id = item.attr("id");
    var myString = id.split("-").pop();

    if (myString == "productname") {
        fetch = index.concat("-batchno");
        product = item.val();
        batch = $("#productsales-"+fetch+"").val();
    } else {
       fetch = index.concat("-productname");
       batch = item.val();
       product = $("#productsales-"+fetch+"").val(); 
    }
    $.get('index.php?r=invoice/bills/get-for-itemid',{ prodname : product,batchno : batch}, function(data){
       alert(data);
       var data = $.parseJSON(data);
       var getItemid = data;
       itemID = "productsales-".concat(index).concat("-itemid");
       $("#"+itemID+"").val(getItemid["itemid"]);
       expDate = "productsales-".concat(index).concat("-expdate");
       $("#"+expDate+"").val(getItemid["expdate"]);
       mRP = "productsales-".concat(index).concat("-mrp");
       $("#"+mRP+"").val(getItemid["mrp"]);
       rATE = "productsales-".concat(index).concat("-rate");
       $("#"+rATE+"").val(getItemid["rateval"]);

   });
}
JS;
$this->registerJs($script, View::POS_END);
/* end getting the itemid */
?>

正在填充的表单字段 -

<?= $form->field($modelsProductsales, "[{$i}]rate")->label(false)->textInput(['maxlength' => true,'class' => 'rate','placeholder' => 'Rate']) ?>

确保您的Productbatch模型具有publica var rateval

class Productbatch extends \yii\db\ActiveRecord
{
    public $rateval
    ...

然后您可以使用

参考视图中的rateval内容

   $model->rateval;

或者当你使用mrp*rate时你得到的结果没有舍入一个简单的解决方案可以在javascript中循环

  Math.round(num * 100) / 100

，在你的情况下

 $("#"+rATE+"").val( Math.round( getItemid["rateval"]*100)/100  );

在yii2查询中使用Round函数
