Yii 2.0將數據從窗體傳遞到控制器

Question

最近，我從CodeIgniter遷移到Yii2.0。

我有一個觀點的形式，用戶可以查看和更新​​數據 我的形式如下：

<form role="form" name="damnedForm" action=""> 
    <div class="form-group"> 
     <label>SKU Code</label> 
     <input class="form-control" name="pSku" value="<?= $model->sku ?>"> 
    </div> 

    <div class="form-group"> 
     <label>Name</label> 
     <input class="form-control" name="pName" value="<?= $model->name ?>"> 
    </div> 

    <div> 
     <button type="submit" class="btn btn-danger">Submit me</button> 
    </div> 
</form> 

我有一個名爲ProductsController的控制器，具有方法：

function actionUpdate($id) { 
     // bla bla bla // 
    } 

我的問題是：

如何將表單中的所有數據傳遞給我的控制器？我必須製作一個手動發佈/獲取方法並將其捕獲到控制器上嗎？或者我可以使用ActiveForm類嗎？

Answer 1

如果你還不知道，Yii2帶有一個叫做Gii的神奇的gode-generator工具。只要您處於dev環境中，您可以使用index.php?r=gii訪問它。

如果您使用此工具爲您的模型創建CRUD，則可以查看代碼如何在視圖和控制器中編寫和收集窗體。

我推薦這種方法，因爲它是做形式的「yii-way」。

歡迎來到Yii！

//您的表單視圖應該是這樣的exerpt

<div class="row"> 
    <div class="col-sm-6"> 
     <div class="the-box"> 
      <h4 class="small-title">Create New Department</h4> 
      <?php 
      $form = $this->beginWidget('CActiveForm', array(
       'id' => 'department-Department-form',

       'enableAjaxValidation' => false,

      ?> 

      <!--<form role="form">-->
