用yii 1实现后台的搜索功能，效果如下图：
1.模型中：
<span> 1</span> <span>public</span> <span>function</span><span> search()
</span><span> 2</span> <span> {
</span><span> 3</span>

</span><span>26</span> <span> }
</span><span>27</span> <span>//</span><span>是否精品</span>
<span>28</span> <span>if</span> (<span>isset</span>(<span>$_GET</span>['goods']['is_best']) && <span>$_GET</span>['goods']['is_best'] != ""<span>)
</span><span>29</span> <span> {

</span><span>39</span> <span> {
</span><span>40</span> <span>$criteria</span>->compare('is_hot',<span>$_GET</span>['goods']['is_hot'<span>]);

<span>43</span> <span> }
</span><span>44</span> <span>return</span> <span>new</span> CActiveDataProvider(<span>$this</span>, <span>array</span><span>(
</span><span>45</span> 'criteria'=><span>$criteria</span>
<span>46</span> <span> ));
</span><span>47</span> }Nach dem Login kopieren
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>
<input type='hidden' name='r' value='B2CShop/b2cGoods/goodsList/id/<?php echo $id ?>'>
<div <span>class</span>="form-group">
<<span>input
name</span>="goods[goods_sn]"<span>
type</span>="text"
<span>class</span>="form-control"<span>
style</span>="width:140px;"<span>
placeholder </span>= "商品货号"<span>
value</span>=<?php <span>echo</span> <span>$_GET</span>['goods']['goods_sn'] ; ?>
>
</div>&<span>nbsp;
</span><div <span>class</span>="form-group">

</div> &<span>nbsp;
</span><div <span>class</span>="form-group">
<?php <span>echo</span> CHtml::dropDownList( "goods[cat_id]" ,
<span>$_GET</span>['goods']['cat_id'] ,<span>

<span>array</span>( "class"=>"form-control" , 'empty'=>'请选择类型...', 'encode' => <span>false</span>, "style"=>"width:140px") ); ?>
</div> &<span>nbsp;
</span><div <span>class</span>="checkbox">

<?php <span>echo</span> <span>$_GET</span>['goods']['is_on_sale']?'checked="checked"':'' ?>

</label>
</div> &<span>nbsp;
</span><div <span>class</span>="checkbox">

</label>
</div> &<span>nbsp;
</span><div <span>class</span>="checkbox">
<label>新品
</span><<span>input
type</span>="checkbox"<span>
name</span>="goods[is_new]"<span>
style</span>="width: 24px;"<span>
value</span>="1"
<?php <span>echo</span> <span>$_GET</span>['goods']['is_new']?'checked="checked"':'' ?>
>
</label>
</div> &<span>nbsp;
</span><div <span>class</span>="checkbox">
<label>热销
</span><<span>input
type</span>="checkbox"<span>
name</span>="goods[is_hot]"<span>
style</span>="width: 24px;"<span>
value</span>="1"
<?php <span>echo</span> <span>$_GET</span>['goods']['is_hot']?'checked="checked"':'' ?>
>
</label>
</div>
<button type="submit" <span>class</span>="btn btn-default"><span <span>class</span>="glyphicon glyphicon-search"></span> 搜 索</button>
</form>
</div>
</div>Nach dem Login kopieren
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。
