可以輸入提現方式以及提現人、提現單號進行多條件查詢。

$data = DB::table('funds_log')->select('funds_log.amount', 'funds_log.source','funds_log.channel','user_info.nickname') -> leftJoin('user_info','funds_log.user_id','=','user_info.user_id');

if ($_REQUEST['type']) {
    $data =  $data->where('channel','like', $_REQUEST['type']);
}

if ($_REQUEST['sn']) {
    $data =  $data->where('source', 'like', '%' . $_REQUEST['sn'] . '%');
}

if ($_REQUEST['name']) {
    $data =  $data->where('nickname', 'like', '%' . $_REQUEST['name'] . '%');
}
$res = $data->get();
