yii criteria select column as 与 时间段查询

需要查询某时间段的记录,但是数据库里只有一个时间记录,如果写sql的话,很快的,放到yii里一时竟然没办法...

不过,最后还是解决了,使用了一个第三方的插件

参考http://www.yiiframework.com/wiki/461/adding-a-date-range-search-for-cgridview-the-easy-way/

按照说明写就可以的,只是有一点,分页的时候,会出错,目前还不知道是哪里造成的,不过不影响大局,先给他列几百条记录出来

先看一个图吧,如果是需要的,往下看,如果不是需要的,就当路过捧个场~~

我这里的具体代码如下,当然,是yii 生成的代码,我稍加改动,懒就一个字

    }



}

我把整个model都粘过来,方便对照查看,另外最上面我定义了一个 public $count_kid  这是因为在yii里,我用到的criteria里有以某个查询结果作为(as)为一个名字来查,这个名字在views里也是需要用到的,所以需要提前定义一下,否则是会出错的,views也一同发一下吧

admin.php

<?php 
$data = $model->search();

    'filter'=>$model,
    'columns'=>array(
        // 'id',
        // 'kid',
        array(
            'name'=>'kid',
            'value'=>'$data->fk_keyword->keyword',
            'filter'=>false, // Set the filter to false when date range searching
        ),
        array(
            'header'=>'搜索次数',
            'value'=>'$data->count_kid',
            'filter'=>false,
        ),
