Yii dropdownlist using $form-> dropdownlist
提问by 5ome
i want to create a form from 2 different models, 1st is for countries, and the 2nd is for documents. The problem is that i can't make a dropdown list, i get the errors all the time.
我想从 2 个不同的模型创建一个表单，第一个用于国家/地区，第二个用于文档。问题是我无法制作下拉列表，我总是收到错误消息。
Here's the code, first my controller.php part
这是代码，首先是我的 controller.php 部分
$model = new Country;
$model2 = new Product;
$this->performAjaxValidation(array($model, $model2));
if(isset($_POST['Country'],$_POST['Product']))
{
// populate input data to $model and $model2
$model->attributes=$_POST['Country'];
$model2->attributes=$_POST['Product'];
// validate BOTH $model and $model2
$valid=$model->validate();
$valid=$model2->validate() && $valid;
if($valid)
{
// use false parameter to disable validation
$model->save(false);
$model2->save(false);
$this->redirect('index');
}
}
...
$countriesIssued = Country::model()->findAll(array('select'=>'code, name', 'order'=>'name'));
...
$this->render('legalisation', array('model'=>$model, 'model2'=>$model2, 'documents'=>$documents, 'countriesIssued'=>$countriesIssued, 'countries'=>$countries, 'flag'=>$flag));
}
In my view script I use this code
在我的视图脚本中，我使用此代码
<?php $form = $this->beginWidget('CActiveForm', array(
'id'=>'user-form',
'enableAjaxValidation'=>true,
)); ?>
<?php echo $form->errorSummary(array($model,$model2)); ?>
<?php echo $form->dropDownList($model, 'countriesIssued',
CHtml::listData($countriesIssued, 'code', 'name'));?>
<?php $this->endWidget(); ?>
but i get this error : Property "Country.countriesIssued" is not defined.
但我收到此错误： 未定义属性“Country.countriesIssued”。
Ok it's not defined, i try to change it to 'countriesIssued', then i got another error saying Invalid argument supplied for foreach().
好的，它没有定义，我尝试将其更改为“countriesIssued”，然后我收到另一个错误，提示为 foreach() 提供的参数无效。
If anybody can help me please. I know there is more solutions on net, i try it but not understand, Thanks.
如果有人可以帮助我，请。我知道网上有更多解决方案，我尝试过但不明白，谢谢。

By definition, the first param of listData is an array; Your is a object;
根据定义，listData 的第一个参数是一个数组；你是一个对象；
<?php
echo $form->dropDownList($model, 'classification_levels_id', CHtml::listData(ClassificationLevels::model()->findAll(), 'id', 'name'),$classification_levels_options);
?>

Make a list variable like this:
像这样创建一个列表变量：
In your Model:
在您的模型中：
$countriesIssued = Country::model()->findAll(array('select'=>'code, name', 'order'=>'name'));
And in your view:
在您看来：
$list = CHtml::listData($countriesIssued, 'code', 'name'));
echo CHtml::dropDownList('Your variable', Your $model,
$list,
array('empty' => '(Select a category'));
