Yii一开发日记-搜索功能及Checkbox的实现

用yii 1实现后台的搜索功能，效果如下图：

1.模型中：

 1 public function search() 2     { 3  4     $criteria = new CDbCriteria; 5         //独立高级搜索 6         if(isset( $_GET['goods'])  ) { 7             //商品货号 8             if (isset($_GET['goods']['goods_sn']) && $_GET['goods']['goods_sn'] != "") 9             {10                 $criteria->compare('goods_sn',$_GET['goods']['goods_sn'], true );11             }12             //商品名称13             if (isset($_GET['goods']['goods_name']) && $_GET['goods']['goods_name'] != "")14             {15                 $criteria->compare('goods_name',$_GET['goods']['goods_name'], true);16             }17             //商品分类18             if (isset($_GET['goods']['cat_id']) && $_GET['goods']['cat_id'] != "")19             {20                 $criteria->compare('cat_id',$_GET['goods']['cat_id'], true);21             }22             //是否上架23             if (isset($_GET['goods']['is_on_sale']) && $_GET['goods']['is_on_sale'] != "")24             {25                 $criteria->compare('is_on_sale',$_GET['goods']['is_on_sale']);26             }27             //是否精品28             if (isset($_GET['goods']['is_best']) && $_GET['goods']['is_best'] != "")29             {30                 $criteria->compare('is_best',$_GET['goods']['is_best']);31             }32             //是否新品33             if (isset($_GET['goods']['is_new']) && $_GET['goods']['is_new'] != "")34             {35                 $criteria->compare('is_new',$_GET['goods']['is_new']);36             }37             //是否热销38             if (isset($_GET['goods']['is_hot']) && $_GET['goods']['is_hot'] != "")39             {40                 $criteria->compare('is_hot',$_GET['goods']['is_hot']);41             }42 43         }44         return new CActiveDataProvider($this, array(45             'criteria'=>$criteria46         ));47 }

2.控制器中:

$model=new B2cGoods('search');

表示在model中启用模型中的search作为搜索。

3.视图中：

class="well">    class="search-box">            

这里需要注意的一点是实现checkbox，保持原状态，echo $_GET['goods']['is_hot']?'checked="checked"':'' ?>，即用php判断是否有值。
