TP5.1 简单使用搜索器withSearch()

一般来说要实现 搜索栏 的多条件搜索功能，传统我们是使用where数组条件添加的

 

注意TP5.1的where数组格式 和TP5.0不同  （大坑！）

$title = Request::param('title');
        $start = $this->request->start_time;
        $end = $this->request->end_time;

        $where[] = ['status', '=', '1'];             //初始查询条件

        if (!empty($start) && !empty($end)) {
            $where[] = [
                ['create_time', 'between time', [intval($start), intval($end)]],   //添加时间查询
            ];
        }

        if (!empty($title)) {
            $where[] = [
                ['title', 'like', '%' . $title . '%'],       //添加标题查询
            ];
        }

        $list = NewsModel()::
        field("id,title,create_time")
            ->where($where)
            ->order('create_time desc')
            ->select();

 

使用搜索器，但时间 和 值为单独0 的查询建议用where[ ]

 

先在模型定义

//定义搜索器
    public function searchTitleAttr($query,$value,$data)
    {
        return $value ? $query->where('title','like','%'.$value.'%') : "" ;
    }

 

控制器中使用  搜索器 + where数组

 

public function test( )
    {
        $limit = $this->request->limit ?? 9999;
        $page = $this->request->page ?? 1;

        $start = $this->request->start_time;
        $end = input('end_time');
        $title = $this->request->title;
        
        $where[] = ['status', '=', '1'];
        if (!empty($time1) && !empty($time2)) {     // 时间搜索
            $where[] = [
                ['create_time', 'between time', [intval($start), intval($end)]],
            ];
        }

        $list = ProductModel::alias('a')
            ->leftJoin('class b', 'a.class_id = b.id')
            ->where($where)
            ->field('a.id,class_id,title,imgs_url,b.type_name')
            ->withSearch(['title'], [
                'title' => $title,
            ])
            ->order('a.id desc')
            ->limit($limit)->page($page)
            ->select()->toArray();

        return jsonApi($list,'查询成功');
    }

 

 

Join联表查询也可以使用

public function test()
    {
        $class_id = $this->request->class_id;
        $title = $this->request->title;

        $list = ProductModel::alias('a')
            ->leftJoin('classification b', 'a.class_id = b.id')
            ->where('a.class_id = b.id')
            ->field('a.id,class_id,title,b.type_name')
            ->withSearch(['class_id', 'title'], [  //哪个表的字段就在哪个模型定义搜索器
                'class_id' => $class_id,
                'title' => $title,
            ])
            ->order('a.id desc')
            ->select()->toArray();
        return $list;
    }
