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：

 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($this, array(
45             'criteria'=>$criteria
46         ));
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：

<div class="well">
    <div class="search-box">
        <form class="form-inline" method="get" action="">
　　　　　　　//指定form表单提交的页面，很重要
            <input type='hidden' name='r' value='B2CShop/b2cGoods/goodsList/id/<?php echo $id ?>'>
            <div class="form-group">
                <input
                        name="goods[goods_sn]"
                        type="text"
                        class="form-control"
                        style="width:140px;"
                        placeholder = "商品货号"
                        value=<?php echo $_GET['goods']['goods_sn'] ; ?>
                >
            </div>&nbsp;

            <div class="form-group">
                <input
                        name="goods[goods_name]"
                        type="text"
                        class="form-control"
                        style="width:140px;"
                        placeholder = "商品名称"　　
                        value=<?php echo $_GET['goods']['goods_name'] ; ?>
                >
            </div>&nbsp;&nbsp;
            <div class="form-group">
                <?php echo CHtml::dropDownList( "goods[cat_id]" ,
                        $_GET['goods']['cat_id'] ,
                        B2cCategory::listData( $id ) ,
                        array( "class"=>"form-control" , 'empty'=>'请选择类型...', 'encode' => false, "style"=>"width:140px") );  ?>
            </div>&nbsp;&nbsp;
            <div class="checkbox">
                <label style="font-size: 16px">上架
                    <input
                            type="checkbox"
                            name="goods[is_on_sale]"
                            style="width: 24px;"
                            value="1"
　　　　　　　　　　　　　　　　//实现checkbox，刷新页面保持原状态
                            <?php echo $_GET['goods']['is_on_sale']?'checked="checked"':'' ?>
                    >
                </label>
            </div>&nbsp;&nbsp;
            <div class="checkbox">
                <label style="font-size: 16px">精品
                    <input
                            type="checkbox"
                            name="goods[is_best]"
                            style="width: 24px;"
                            value="1"
                            <?php echo $_GET['goods']['is_best']?'checked="checked"':'' ?>
                    >
                </label>
            </div>&nbsp;&nbsp;
            <div class="checkbox">
                <label style="font-size: 16px">新品
                    <input
                            type="checkbox"
                            name="goods[is_new]"
                            style="width: 24px;"
                            value="1"
                            <?php echo $_GET['goods']['is_new']?'checked="checked"':'' ?>
                    >
                </label>
            </div>&nbsp;&nbsp;
            <div class="checkbox">
                <label style="font-size: 16px">热销
                    <input
                            type="checkbox"
                            name="goods[is_hot]"
                            style="width: 24px;"
                            value="1"
                            <?php echo $_GET['goods']['is_hot']?'checked="checked"':'' ?>
                    >
                </label>
            </div>
            <button type="submit" class="btn btn-default"><span class="glyphicon glyphicon-search"></span>&nbsp;搜&nbsp;索</button>
        </form>
    </div>
</div>

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