这是我的PHP代码

$dbhost = "127.0.0.1";
$dbuser = "root";
$dbpass = "";
$dbname = "mss";
$connection = mysql_connect($dbhost, $dbuser, $dbpass, $dbname);
if (mysql_errno()) {
    die("Database Connection failed:" . mysql_error() . "(" . mysql_errno() . ")");
}
mysql_select_db('mss');
?>
<?php echo $id = (isset($_POST['id']) ? $_POST['id'] : "hello"); ?> <br>
<?php echo $title = (isset($_POST['title']) ? $_POST['title'] : "hello"); ?> <br>
<?php echo $employee = (isset($_POST['employee']) ? $_POST['employee'] : "hello"); ?> <br>
<?php
$participant = (isset($_POST['participant']) ? $_POST['participant'] : "hello");
$starttime = (isset($_POST['starttime']) ? $_POST['starttime'] : "hello");
$endtime = (isset($_POST['endtime']) ? $_POST['endtime'] : "hello");
$day = (isset($_POST['day']) ? $_POST['day'] : "hello");
$room = (isset($_POST['room']) ? $_POST['room'] : "hello");
$Lines = explode("\n", $participant);
foreach ($Lines as $line) 
{
    echo $line;
    $q1 = "select Availability from E_schedule where Employee_name='$line' and StartTime='$starttime' and Day='$day'";
    $q2 = "SELECT Availability from room_schedule WHERE r_name = '$room' AND StartTime='$starttime' and Day='$day'";
    $result = mysql_query($q1, $connection);
    $result1 = mysql_query($q2, $connection);
    if ($result == FALSE)
    {
        die(mysql_error());
    }
    if ($result1 == FALSE)
    {
        die(mysql_error());
    }
        $info = mysql_fetch_array($result);
        $info1 = mysql_fetch_array($result1);
        if ($info['Availability'] == 1) {
            echo ("You can't make a meeting at that time, Please Select another Day or time");
        }

你能帮忙吗？我尝试了很多东西而且没有用提前谢谢

Answer 1

你不必在mysql_connect函数中传递$ dbname。

$dbhost = "127.0.0.1";
$dbuser = "root";
$dbpass = "";
$dbname = "mss";
$connection = mysql_connect($dbhost, $dbuser, $dbpass);

我需要更多信息才能找出问题所在。发布您收到的错误消息

Answer 2

您使用折旧mysql的原因是什么？

使用PHP5.x：

PDO
MySQLi

接下来，我可能错过了它;但是我没有看到你消毒你的用户输入;这不是一件安全的事情。

至于你的确切问题，我只看到$participant的一个帖子值。所以，我假设你只收集字段名称的第一个结果。

无法使用php和mysql插入数据库
