Question

我尝试了多种方法来做到这一点，我只是在智慧结束。我正在尝试检查飞机预订日历中特定日期的重叠时间。

这是我的表格：

<form action="add-schedule.php" method="post">
            Aircraft:<BR>
            <input type="text" value="<?php echo $_GET["air"]; ?>" name="aircraft" readonly><BR><BR>
            Pilot in Command:<BR>
            <input type="text" value="<?php echo $user; ?>" name="user" readonly><BR><BR>
            Date:<BR>
            <input type="text" value="<?php echo date('Y-m-d', strtotime($_GET["dt"])); ?>" name="dt" readonly><BR><BR>
            Start Time:<BR>
            <input type="time" name="tm" required><BR><BR>
            End Time:<BR>
            <input type="time" name="et" required><BR><BR>
            <input type="submit"><BR><BR>
            </form><BR>

这是我的添加文件：

    <?php
    include('connect.php');

    $name = mysqli_real_escape_string($con, $_POST['aircraft']);
    $user = mysqli_real_escape_string($con, $_POST['user']);
    $dt = mysqli_real_escape_string($con, $_POST['dt']);
    $tm = mysqli_real_escape_string($con, $_POST['tm']);
    $et = mysqli_real_escape_string($con, $_POST['et']);
    $TM = date('H:i:s', strtotime($tm));
    $ET = date('H:i:s', strtotime($et));

    if ($result = $con->query("SELECT * FROM cal WHERE ( '$TM' BETWEEN cal_time 
AND cal_end) OR ('$ET' BETWEEN cal_time AND cal_end) OR (cal_time < '$TM' 
AND cal_end > '$ET') AND cal_date = '$dt' AND cal_air = '$name'"))
    {
        if ($result->num_rows > 0)
        {

            header("location:add-sched-error.php");
        }

    }

    $sql = "INSERT INTO cal (cal_air, cal_user, cal_date, cal_time, cal_end) 
    VALUES('$name', '$user', '$dt', '$tm', '$et')";

    if (!mysqli_query($con, $sql))
    {
        die('Error: '.mysqli_error($con));
    }
    header("location:aircraft-schedule.php");

    mysqli_close($con);
    ?>

我在这里缺少什么？

我尝试使用您的代码和测试数据库，除了OR和AND查询中SELECT和if ($result = $con->query("SELECT * FROM cal WHERE ( ( '$TM' BETWEEN cal_time AND cal_end) OR ('$ET' BETWEEN cal_time AND cal_end) OR (cal_time < '$TM' AND cal_end > '$ET') ) AND cal_date = '$dt' AND cal_air = '$name'")) { if ($result->num_rows > 0) { header("location:add-sched-error.php"); } }的组合之外，它几乎可以使用。将时间检查包含在一组额外的括号中为我工作：

import operator
from zeep import Client

wsdl = 'http://www.soapclient.com/xml/soapresponder.wsdl'
client = Client(wsdl=wsdl)
for service in client.wsdl.services.values():
    print "service:", service.name
    for port in service.ports.values():
        operations = sorted(
            port.binding._operations.values(),
            key=operator.attrgetter('name'))

        for operation in operations:
            print "method :", operation.name
            print "  input :", operation.input.signature()
            print "  output:", operation.output.signature()
            print
    print
