Question

基本上。我有两件事有问题：

我正在使用动态表单，用户可以根据需要添加任意数量来输入手头的所有发票。我有一个字段（invoice_loadamount），我想要汇总所有invoice_loadamount字段。因此，如果用户生成3个表单，我希望它总结动态表单一（invoice_loadamount字段1）+动态表单二。（invoice_loadamount字段2）+动态表单三（invoice_loadamount字段3）。我该怎么做？从他生成的每个表单中自动对此字段求和吗？
我的第二个问题是我想从表中检索数据（车辆，列vehicle_capacity），然后以这样的方式进行比较，即它将验证总和是否大于vehicle_maxcap，然后如果是，则给出错误。

我的表格：

Answer 1

从HTML <input type="text" id="invoices-0-invoice_loadamount" class="form-control" name="Invoices[0][invoice_loadamount]" maxlength="100">可以看出，loadamount输入字段是这样的。因此，在控制器端，创建功能或更新功能将接收发布数据作为$ _POST [＆＃39; Invoices＆＃39;]作为数组

array( 
    "0"=>array("invoice_number" => "132412", "invoice_loadamount" =>"34.00", "invoice_date" =>"2015-03-04"),
    "1"=>array("invoice_number" => "352223", "invoice_loadamount" =>"233.00", "invoice_date" =>"2016-03-04"),
    ...
);

其中0,1表示添加的每个表单。在你的情况下形成一个，形成两个等。

您需要做的只是循环从数组中获取的数组。像这样：

if (Yii::$app->request->isPost) {
    $data = Yii::$app->request->post();
    $invoices = $data['Invoices'];
    $total = 0;
    if(sizeof($invoices) > 0){
         foreach($invoices as $one_invoice){
             $one_loadamount =  floatval($one_invoice['invoice_loadamount']);
             $total += $one_loadamount;
         }
    }
    //then you get the total amount as $total
}

对于问题2，您可以（假设您已经拥有vehicle_id）。

$vehicle = Vehicles::find()->where(['id'=>$vehicle_id])->one();
if($total > $vehicle->maxcap){
    \Yii::$app->getSession()->setFlash('danger', 'Total is larger than max cap');
}

由于第二个问题取决于特定的车辆，因此您需要先获得其身份。

使用生成的表单上的数据动态表单操作？ yii2
