php下拉选项的批量操作的实现代码_PHP教程

实现功能，操作项可以单独删除，批量项可以批量删除，批量显示，隐藏（改广告的数据库的status_is的值）；

1.视图关键点：

复制代码 代码如下:

        id?>

复制代码 代码如下:

         
          全选
         
            选择操作
            删除
            显示
            隐藏
         
         
       

复制代码 代码如下:

/*单个删除*/

2.控制器：

复制代码 代码如下:

/**
     * 批量操作
     *
     */
    public function actionBatch ()
    {
        if (XUtils::method() == 'GET') {     //单个删除是get方式
            $command = trim($_GET['command']);
            $ids = intval($_GET['id']);
        } else
            if (XUtils::method() == 'POST') {
                $command = trim($_POST['command']);
                $ids = $_POST['id'];
                is_array($ids) && $ids = implode(',', $ids);
            } else {
                XUtils::message('errorBack', '只支持POST,GET数据');
            }
        empty($ids) && XUtils::message('error', '未选择记录');

        switch ($command) {

            case 'adDelete':
                parent::_acl('ad_delete');
                parent::_adminiLogger(array('catalog'=>'delete', 'intro'=>'删除广告，ID:'.$ids));
                parent::_delete(new Ad(), $ids, array ('ad' ), array ('attach_file' ));
                break;
            case 'adVerify':
                parent::_acl('ad_verify');
                parent::_adminiLogger(array('catalog'=>'delete', 'intro'=>'广告状态变更为显示，ID:'.$ids));
                parent::_verify(new Ad(), 'verify', $ids, array ('ad' ));

                break;
            case 'adUnVerify':
                parent::_acl('ad_verify');
                parent::_adminiLogger(array('catalog'=>'delete', 'intro'=>'广告状态变更为隐藏，ID:'.$ids));
                parent::_verify(new Ad(), 'unVerify', $ids, array ('ad' ));
                break;
            default:
                throw new CHttpException(404, '错误的操作类型:' . $command);
                break;
        }

    }

父类的删除函数：

复制代码 代码如下:

protected function _delete ($model = null, $id = '', $redirect = 'index', $attach = null, $pkField = 'id')
    {
        if ($attach) {          //如果有附件要删除广告的图片
            $data = $model->findAll($pkField . ' IN(:id)', array (':id' => $id ));
            foreach ((array) $data as $row) {
                foreach ((array) $attach as $value) {
                    if (! empty($row[$value])) {
                        @unlink($row[$value]);
                    }
                }
            }
        }
        $result = $model->deleteAll(array ('condition' => 'id IN(' . $id . ')' ));
        //刷新缓存
        self::_refreshCache($model);
        $this->redirect($redirect);
    }

复制代码 代码如下:

protected function _verify ($model = null, $type = 'verify', $id = '', $redirect = 'index', $cdField = 'status_is', $pkField = 'id')
    {
        $criteria = new CDbCriteria();
        $criteria->condition = $pkField . ' IN(' . $id . ')';
        $showStatus = $type == 'verify' ? 'Y' : 'N';
        $result = $model->updateAll(array ($cdField => $showStatus ), $criteria);
        //刷新缓存
        self::_refreshCache($model);
        $this->redirect($redirect);
    }
