Yii 1开发日记，yii开发日记

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>$model</span>=<span>new</span> B2cGoods('search');

Nach dem Login kopieren

表示在model中启用模型中的search作为搜索。

3.视图中：

<div <span>class</span>="well">
    <div <span>class</span>="search-box">
        <form <span>class</span>="form-inline" method="get" action=""><br />　　　　　　　<span>//指定form表单提交的页面，很重要</span>

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。
