＆＃13;

我想要做的是：当我有新的预订时，请更改字段＆＃39; idbook＆＃39;取决于书的日期（参见：今日字段）和idroom，每个行的预订ID和可用性为1 在模型中我有这个代码（注意＆＃34;调试＆＃34;）

function updateAvailability($data)
    {

    $this->db->select('idbook');
    $this->db->where('idguests',$data['guestid']);
    $this->db->where('valid_from',$data['from_date']);
    $this->db->where('valid_to',$data['to_date']);
    $this->db->where('idroom',$data['idroom']);
    $query = $this->db->get('bookitbooking');

    $result = $query->row();
    $idbook = $result->idbook;

    $changes = array(
        'idbook' => $idbook,
        'availability' => 1
    );
    $where = array(
        'today' => "BETWEEN '{$data['from_date']}' AND '{$data['to_date']}'",
        'idroom' => $data['idroom']
    );

    $update = $this->db->update('bookitavailability',$changes,$where);
    if( $update === TRUE){
        echo "done";
    } else {
        echo "wrong";
    }

}

出于某种原因，上面的代码不起作用，我有一个＆＃34;完成＆＃34;返回回显，但我的数据库没有变化。

Answer 1

尝试仔细检查此字符串：

"BETWEEN '{$data['from_date']}' AND '{$data['to_date']}'"

到

"BETWEEN ".$data['from_date']." AND ".$data['to_date']

Answer 2

问题可能是$ data [＆＃39; from_date＆＃39;]是一个字符串，因此它可能没有正确的行。

尝试

"BETWEEN DATE(".$data['from_date'].") AND DATE(".$data['to_date'] . ")"

Answer 3

好的...所以，因为我看到where子句无法按照我想要和希望运行的问题，我对代码进行了一些更改。
首先，我为日期做了一个foreach（）循环，然后我在每个循环中传递了我想要的 where 语句的日期。这是我“解决”它的方式。


function updateAvailability($data)
    {
        $this->db->select('idbook');
        $this->db->where('idguests',$data['guestid']);
        $this->db->where('valid_from',$data['from_date']);
        $this->db->where('valid_to',$data['to_date']);
        $this->db->where('idroom',$data['idroom']);
        $query = $this->db->get('bookitbooking');

        $result = $query->row();
        $idbook = $result->idbook;

        $changes = array(
            'idbook' => $idbook,
            'availability' => 1
        );

        $arrival = new DateTime($data['from_date']);
        $departure = new DateTime($data['to_date']);
        $interval = DateInterval::createFromDateString('1 day');
        $period = new DatePeriod($arrival, $interval, $departure);

        foreach($period as $day){
            $this->db->where('idroom',$data['idroom']);
            $this->db->where('today',$day->format('Y-m-d'));
            $this->db->update('bookitavailability',$changes);
        }
    }

mysql＆amp; codeigniter更新多行
