Yii 一开发日记 - 搜索功能及Checkbox的实现

Yii 1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：

2.控制器中:

<span style="color: #800080;">$model</span>=<span style="color: #0000ff;">new</span> B2cGoods('search');

表示在model中启用模型中的search作为搜索。

3.视图中：

</div>

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。
