Question

我反复犯同样的错误。下拉数据不是从表单中获取的。我的代码在这里

这是我的控制器：ProductController

{<?php

class ProductController extends Controller
{
    public function actionCreate()
    {
        $model=new CreateForm;
    // collect user input data
        if(isset($_POST['CreateForm']))
        {
            $model->attributes=$_POST['CreateForm'];
                        $model->setAttributes($_POST['CreateForm']);
            // validate user input and redirect to the previous page if valid
            if($model->validate())
                        { 
                        $product=new Product;
                        $product->save();
                        }
                        else {
                            echo "Hi";
                        }
        }
        // display the login form
        $this->render('create',array('model'=>$model));


    }
}
?>}

我的模特：CreateForm

 {<?php

    class CreateForm extends CFormModel
    {
        public $product_name;
        public $category_name;
        public $description;


        public function rules()
        {
            return array(
                array('product_name, category_name, description', 'required'),
               array('product_name', 'unique', 'className' => 'Product', 'attributeName' => 'product_name', 'message'=>'This product name is already in use'),
            );

        }

        public function attributeLabels()
        {
            return array(
                'product_name'=>'PRODUCT NAME',
                        'category_name'=>'CATEGORY',
                        'description'=>'DESCRIPTION'
            );
        }



    }
    ?>

}

分类

{
<?php
class Category extends CActiveRecord
{
    public static function model($className=__CLASS__)
    {
        return parent::model($className);
    }
    public function tableName()
    {
        return 'category';
    }

   public function attributeLabels()
    {
        return array(
            'category_id'=>'CATEGORY ID',
                    'category_name'=>'CATEGORY NAME',

        );
    }    
}
?>}

我的观点：create.php

{<?php
$this->pageTitle=Yii::app()->name . ' - Create';
$this->breadcrumbs=array(
    'Create',
);
?>

<h1>CREATE</h1>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'create-form',
    'enableAjaxValidation'=>true,
    'enableClientValidation'=>true,

)); 

?>


    <p class="note">Fields with <span class="required">*</span> are required.</p>

    <div class="row">
        <?php echo $form->labelEx($model,'product_name'); ?>
        <?php echo $form->textField($model,'product_name'); ?>
        <?php echo $form->error($model,'product_name'); ?>
    </div>

    <div class="row">

        <?php
             echo $form->labelEx($model,'category_name');   
                $records = Category::model()->findAll();
               $list = CHtml::listData($records, 'category_id', 'category_name');
                echo CHtml::DropDownList('category_name', null, $list, array('prompt'=>'select '));
               echo $form->error($model,'category_name');
                ?>

    </div>

    <div class="row">
            <?php echo $form->labelEx($model,'description'); ?></br>
        <?php echo $form->textArea($model,'description',array('style' => 'height:100px;width:500px;','maxlength'=>500)); ?>
        <?php echo $form->error($model,'description'); ?>
    </div>

    <div class="row submit">
        <?php echo CHtml::submitButton('CREATE'); ?>
    </div>

<?php $this->endWidget(); ?>
</div><!-- form -->
}

如果我输入所有字段，则会再次出现错误，指出“PLS输入类别”

Answer 1

你所做的就是大规模的作业

$model->attributes=$_POST['CreateForm'];

这不会分配所有值，也不安全处理数据

仅当数据在模型中处于安全状态时才会保存数据

您将重新声明发布的数据

$model->attributes=$_POST['CreateForm'];
$model->dropdownname=$_POST['CreateForm']['dropdownname'];

希望这会对你有所帮助

我认为你改变了下拉代码。

<?php
echo $form->labelEx($model,'category_name');   
$records = Category::model()->findAll();
$list = CHtml::listData($records, 'category_id', 'category_name');
echo CHtml::DropDownList('category_name', null, $list, array('prompt'=>'select '));
echo $form->error($model,'category_name');
?>

到

<?php
echo $form->labelEx($model,'category_name');   
$records = Category::model()->findAll();
$result = array();
foreach($records as $p) {
  $result[p->category_id] = p->category_name ;     
}
echo CHtml::activeDropDownList($model, 'category_name', $result);
echo $form->error($model,'category_name');
?>

现在您需要检查，您的类别ID或名称是否来了。然后调试控制器文件，如下所示。

public function actionCreate()
{
  $model=new CreateForm;
  // collect user input data
  if(isset($_POST['CreateForm']))
  {
  $model->attributes=$_POST['CreateForm'];

  echo $model->category_id ;
  exit ; // Finish program here, and drop down will be printed.  

  $model->setAttributes($_POST['CreateForm']);
  // validate user input and redirect to the previous page if valid
  if($model->validate())
  { 
  $product=new Product;
  $product->save();
  }
  else {
  echo "Hi";
  }
  }        // display the login form
  $this->render('create',array('model'=>$model));
}

希望对你有所帮助。

由于

DROPDOWN列表未提取的输入值
