Question

我的控制器（我想根据某些条件选择记录）：

public function promotion()
{
    if(!$this->user_permission->check_permission())return;

        $data['startDate'] = $this->input->post('input_date_from');
        $data['endDate'] = $this->input->post('input_date_to');
        $email = $this->input->post('email');

    var_dump($email);
    var_dump($data['startDate']);
    var_dump($data['endDate']);

    $this->db->select('a.booking_id as booking_id, a.from_email as from_email, a.booking_date as booking_date, a.status as status, b.vendor_airway_bill as awb, b.tariff as tariff');
    $this->db->where('from_email', $email);
    $this->db->where('booking_date >=', date('Y-m-d',strtotime($data['startDate'])));
    $this->db->where('booking_date <=', date('Y-m-d',strtotime($data['endDate'])));
    $this->db->where('status = 1');
    $this->db->or_where('status = 2');
    $this->db->from('booking as a');
    $this->db->join('shipment as b','a.booking_id = b.booking_id','left');      
    $query = $this->db->get();
    $data['result'] = $query->result_array();

    $this->template->render('admin/promotion',$data,'admin');

}

我的观点（我想根据用户输入显示基于from_email的预订货件。我将表格设置为display:none，当用户在from_email输入内输入内容时，请点击view，它显示数据表）：

<form action="" method="post" id="cashback">
    User Email :
    <input type="text" name="email" id="email">
    Booking Date :
    <div id="daterange" style="background: #fff; cursor: pointer; padding: 5px 10px; border: 1px solid #ccc; display:inline">
     <span></span> <b class="caret"></b>
    </div>
    <input type="hidden" name="input_date_from" id="input_date_from" value="">
    <input type="hidden" name="input_date_to" id="input_date_to" value="">
   <button type="button" class="btn btn-primary" onclick="promotion();">View
   </button>
</form>

<table class="table table-bordered table-striped table-condensed" id="promotion" style="display:none">
        <thead>
            <tr>
                <th>BookingDate</th>
                <th>UserEmail</th>
                <th>AirwayBill</th>
                <th>Tariff</th>
                <th>Status</th>
            </tr>
        </thead>
        <tbody>
        <?php foreach ($result as $r) : ?>
            <tr>
                <td>
                    <?php echo $r['booking_date'];?>
                </td>
                <td>
                    <?php echo $r['from_email'];?>
                </td>
                <td>
                    <?php echo $r['awb'];?>
                </td>
                <td>
                    <?php echo $r['tariff'];?>
                </td>
                <td>
                    <?php echo $r['status'];?>
                </td>
            </tr>

            console.log(input_date_to);
        }
    })
}

</script>

我尝试根据from_email，date_range_from和date_range_to过滤数据。当我var_dump输入帖子时，它会显示我预期的值，但它没有运行this->db->where('from_email',$email)，所以我得到了所有结果..

Answer 1

尝试替换

$this->db->where('status = 1');
$this->db->or_where('status = 2');

成像：

$this->db->where('(status = 1 OR status = 2)');

注意括号对于使OR运算符获得比AND运算符更高的优先级非常重要。还要打开查询日志并检查将哪些实际SQL发送到数据库服务器以更好地理解原因。

Answer 2

[解决]。使用where_in()代替or_where

codeigniter multiple where子句不起作用
