n00b at OOP and yii。我很难理解yii以及它如何将变量传递给视图。我有1个模型，访问mt数据库，也是一个形式，我可以张贴一个字符串和复选框值被添加到数据库。从gii构建的预构建页面中发布和检索工作良好。但我想做的是有形式和"读"从数据库都在同一页上。因此，当通过表单发布帖子时，它会被添加到同一页面底部的"历史"类型部分。
我能把<?php $this->renderPartial('_form', array('model'=>$model)); ?>添加到我的索引页吗??显然不是因为我得到一个错误:Undefined variable: model .
模型:
<?php
/**

*
* The followings are the available columns in table 'fb_post':

<h1>Fb Posts</h1>
<?php

?>
<?php $this->widget('zii.widgets.CListView', array(
'dataProvider'=>$dataProvider,
'itemView'=>'_view',
)); ?>
表单需要一个模型，它的数据被张贴，你必须在控制器actionIndex中创建模型，并将其传递给索引视图。例子:
class FbPostController extends Controller
{
...
public function actionIndex()
{
// Create model
$model=new FbPost;
// Process posted form data if any
if (isset($_POST['FbPost']))
{
$model->attributes=$_POST['FbPost'];
$model->save();
}
$dataProvider=new CActiveDataProvider('FbPost');
$this->render('index',array(
'dataProvider'=>$dataProvider,
'model'=>$model,
));
}
...
}
现在你可以添加你的代码:
<?php $this->renderPartial('_form', array('model'=>$model)); ?>
