laravel中when的使用

单个条件

model::when($data,function ($query,$data){
            $query->where("搜索字段",$data['搜索字段']);
        })->get();
        

多个条件

$searchData = model::when($data,function ($query,$data){
                 $query->where("搜索字段",$data['搜索字段']);
            })->when($data,function ($query,$data){
                 $query->where("搜索字段",$data['搜索字段');
            })->when($data,function ($query,$data){
                 $query->where("搜索字段",$data['搜索字段']);
            })->get();

 多个条件+模型关联+保留分页

$searchData = model::with([关联模型])->when($data,function ($query,$data){
                if($data['is_reply'] != ""){
                    $query->where("is_reply",$data['is_reply']);
                }
            })->when($data,function ($query,$data){
                if($data['store_name'] != ""){
                    $id = model::where('store_name','like',$data['store_name']."%")->get('id')->toArray();
                    foreach ($id as $k=>$v){
                        $query->where("product_id",$v);
                    }
                }
            })->when($data,function ($query,$data){
                if($data['real_name'] != ""){
                    $uid = model::where('real_name','like',$data['real_name']."%")->get('uid')->toArray();
                    foreach ($uid as $k=>$v){
                        $query->where("uid",$v);
                    }
                }
            })->paginate(5);
