laravel 根据某条件进行排序 示例

public static function fence_vehicle_list($params,$page,$perpage,$fence_index_id)

{

$getobjlist = self::getlistobj($params,$page,$perpage);

//根据 是否绑定 做下 筛选  count

    $newcondition = [];

if (!empty($params["is_bind"])) {

switch ($params["is_bind"]) {

case 'y':

                $newcondition = "if(fb.fence_index_id=".$fence_index_id.",1,0) = 1";

break;

case "n";

$newcondition = "if(fb.fence_index_id=".$fence_index_id.",1,0) = 0";

break;

}

}

$obj = $getobjlist["obj"];

$obj_count = $getobjlist["obj_count"];

$obj = $obj->join('st_fence_bind as fb',function ($join)use ($fence_index_id) {

$join->on('fb.vehicle_id','=','veh.id')

->where('fb.fence_index_id','=',$fence_index_id)

->where('fb.is_delete','=',0);

},null,null,"left")

->select(array_merge(Vehicle::$filed_list, ["fb.fence_index_id"]))

->selectRaw("if(fb.fence_index_id=" . $fence_index_id . ",1,0) as have_bind")

->orderByRaw("have_bind  desc");

if (!empty($newcondition)) {

$obj = $obj->whereRaw($newcondition);

}

$obj = $obj->get();

$obj ? $getobjlist["list"]= $obj->toArray(): [];

$getobjlist["count"]= $obj_count->count();

unset($getobjlist["obj"]);

unset($getobjlist["obj_count"]);

return $getobjlist;
