如何在CGridView Yii Framework中添加下拉菜單？

Question

我想將CGridView文本字段更改為下拉菜單，並將數字更改為類別名稱。

$model = new Products('search');
        $model->unsetAttributes();  
        if(isset($_GET['Products'])){
           $model->attributes=$_GET['Products'];
        }

並在視圖中。

<?php
       $this->widget('zii.widgets.grid.CGridView', array(
       'dataProvider'=>$model->search(),                               
       'columns'=>array(                                                                                                                                                       'code',
            'category_id',
            'quantity',
            ),
           'filter'=>$model,
        ));
    ?>

Answer 1

只需寫上“ category_id”代替，

array(
           // 'name' => 'category_id',
             'header'=>'Category Name',
            'value' => '$data->categoryname($data->category_id)',
            'filter' => $categoryArray
        ),


categoryname() should be written in your `Product Model`.  



  Product Model
public function categoryname($category_id){
//fetch your category name with this category id and return it

return categoryName;
}

和$categoryArray應該是一個數組，鍵為類別ID，值作為category_name

$categoryArray = CHtml::listData(Category::model()->findAll() 'category_id', 'category_name')
