[抛砖引玉]小说管理页多条件搜索

原来的小说管理无法并行搜索多个条件，所以做了下修改

这个非常简单，一眼就懂

效果如图：

application/admin/controller/Novel.php

...
public function index(){
        $Novel=model('novel');
        $map[]  = ['sole','>',1];
        $list = $Novel->lists($map);
        // 获取所有参数
        $params = $this->request->param(false);
        // 过滤参数
        $params = array_filter($params,function($k) {
            return in_array($k,
                ['category','position','serialize','order','status','keywords']);
        }, ARRAY_FILTER_USE_KEY);
        $this->assign('params', $params);
        $this->assign('list', $list);
        $this->assign('category', get_tree(0));
        $this->assign('meta_title','小说列表');
        return $this->fetch();
    }
...
