我有这些表:(在问题中截断了不需要的列)
间: room_id | room_type_id | room_number
room_types: room_type_id | room_type | room_type_default_price
保留: reservation_id room_type |签到|结帐
当用户通过输入所需的房间类型,到达日期,出发日期来搜索可用房间时,必须在下拉列表中填写可用的房间类型。然而,有两个问题,一个是已知的,一个是未知的。 下面的代码只返回页面(视图)加载时“数组到字符串转换错误”。
已知的问题是,房间类型的下拉列表也填充了来自room_types表的数据。对于JS / jQuery计算,我在填充时连接了room_type列和room_type_default_price列。所以生成的HTML是这样的:
双人间
因此,用户输入$ room_type,例如“Double Room_20000”,其中最初没有列数据存在。在房间类型表中,room_type列虽然有“双人房”。如何将这两个值分开并将room_type_id设置为$ room_type_id?
型号:
function searchRoomType($room_type) {
$query = $this->db->query(" SELECT room_type_id FROM room_types WHERE room_type = '$room_type' LIMIT 1");
return $query->result();
//return $room_type_id;
//print_r ($room_type_id);
}
function searchRooms($room_type, $start_date, $end_date, $tmpRoomNumber = array()) {
$room_type_id = $this->searchRoomType($room_type);
$query = $this->db->query(
"SELECT a.room_number
FROM rooms a LEFT OUTER JOIN ( SELECT room_number
FROM reservations
WHERE checkin >= '$start_date'
AND checkout <= '$end_date'
) b
ON a.room_number = b.room_number
WHERE a.room_type_id = '$room_type_id'
AND a.housekeeping_status = 'Clean'
AND b.room_number is NULL
GROUP BY a.room_type_id
ORDER BY a.room_number ASC");
if($query->num_rows()>0) {
foreach($query->result_array() as $row) {
$tmpRoomNumber[$row['room_number']] = $row['room_number'];
}
}
return $tmpRoomNumber;
}
答案 0 :(得分:0)
我认为您应该像这样更改函数searchRoomType
function searchRoomType($room_type) {
$query = $this->db->query(" SELECT room_type_id FROM room_types WHERE room_type = '$room_type' LIMIT 1");
foreach ($query->result() as $row)
{
$room_type_i=$row->room_type_id;
}
return $room_type_id;
}
