if(isset($_POST['submit2']))

$useremail=$_SESSION['login'];
$date=$_POST['date'];

        </form>
<?php }} ?>

我稍微简化了代码（包括对 $useremail 和 $pid 的值进行硬编码）以确定可能导致问题的原因，并且它第一次就起作用了：

<?php 
  // DB credentials.
  define('DB_HOST','localhost');
  define('DB_USER','root');
  define('DB_PASS','');
  define('DB_NAME','test');
  // Establish database connection.
 try
  {
    $dbh = new PDO("mysql:host=".DB_HOST.";port=3307;dbname=".DB_NAME,DB_USER, DB_PASS,array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
  }
 catch (PDOException $e)
  {
      exit("Error: " . $e->getMessage());  
   }
?>

<?php

 if(isset($_POST['submit2']))
  {
    $pid=6;
    $useremail= "hello@domain.com";
    $date=$_POST['date'];
    $time=$_POST['time'];
    $comment=$_POST['comment'];
    $status=0;
    $sql="INSERT INTO tblbooking (PackageId, UserEmail, BDate, BTime, Comment, status) VALUES (:pid, :useremail , :bdate , :btime , :comment , :status);";
    $query = $dbh->prepare($sql);
    $query->bindParam(':pid',$pid,PDO::PARAM_STR);
    $query->bindParam(':useremail',$useremail,PDO::PARAM_STR);
    $query->bindParam(':bdate',$date,PDO::PARAM_STR);
    $query->bindParam(':btime',$time,PDO::PARAM_STR);
    $query->bindParam(':comment',$comment,PDO::PARAM_STR);
    $query->bindParam(':status',$status,PDO::PARAM_STR);
    $query->execute();
  }
?>

<form name="book" method="post">
     <label class="inputLabel">Date</label>
     <input type="text" name="date" required="">
     <div class="bnr-right">
        <label class="inputLabel">Time</label>
        <input type="text" name="time" required="">
     </div>
     <label class="inputLabel">Comment</label>
     <input class="special" type="text" name="comment">
      <button type="submit" name="submit2" class="btn-primary btn">Book</button>          
 </form>
