Question

我不断收到此错误消息：

致命错误：未捕获的异常＆＃39; PDOException＆＃39;消息＆＃39; SQLSTATE [HY093]：参数号无效：参数未定义＆＃39;在[CENSORED] /add_test.php:93堆栈跟踪：＃0 [CENSORED] /add_test.php(93）：PDOStatement-＆gt;执行（）＃1 {main}在第93行的[CENSORED] /add_test.php中抛出

代码如下：

    $test_name = $_POST['test_name'];
    $start_date = $_POST['start_date'];
    $start_time = $_POST['start_time'];
    $end_date = $_POST['end_date'];
    $end_time = $_POST['end_time'];
    $teacher_id = $_POST['teacher_id'];

    if(isset($_POST['test'])){
      $exam_mode = "1";  
    }

    else{
      $exam_mode = "0";
    }

    $subject = $_POST['subject'];
    $max_score = $_POST['maxs'];
    $qtext = $_POST['qtext'];
    $qtitle = $_POST['qtitle'];
    $critsel = $_POST['criteria_selector'];
    $crita = $_POST['criteria'];
    $edit = $_POST['editable_response'];
    $pinnumber = mt_rand(1000000,9999999);

    $start_datetime = $start_date;
    $start_datetime .= ":";
    $start_datetime .= $start_time;
    $true_start_time = date_create_from_format("d.m.Y:H.i",$start_datetime);
    $db_start_time = $true_start_time->format("Y-m-d H:i:s"); 

    $end_datetime = $end_date;
    $end_datetime .= ":";
    $end_datetime .= $end_time;
    $true_end_time = date_create_from_format("d.m.Y:H.i",$end_datetime);
    $db_end_time = $true_end_time->format("Y-m-d H:i:s"); 

    include ('config.php');

        try {
        $cnnxn = new PDO("mysql:host=$db_host;dbname=$db_name", $db_username, $db_password);
    } catch (PDOException $e) {
        die("ERROR: " . $e->getMessage());
    }
    $cnnxn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $cnnxn->exec("SET NAMES utf8");
    $query = $cnnxn->prepare("INSERT INTO assignments (teacher, start, end, exam, question_text, criteria, criteria_visibility, question_title, subject, pin, editable, max_score) VALUES (:teacher, :start, :end, :exam, :question_text, :criteria, :criteria_visibility, :question_title, :subject, :pin, :editable, :max_score)");
    $query->bindParam(':teacher', $userid);
    $query->bindParam(':start', $db_start_time);
    $query->bindParam(':end', $db_end_time);
    $query->bindParam(':exam', $exam_mode);
    $query->bindParam('::question_text', $qtext);
    $query->bindParam(':criteria', $crita);
    $query->bindParam(':criteria_visibility', $critsel);
    $query->bindParam(':question_title', $qtitle);
    $query->bindParam(':subject', $subject);
    $query->bindParam(':pin', $pinnumber);
    $query->bindParam(':editable', $edit);
    $query->bindParam(':max_score', $max_score);
    $query->execute();

    if ($query !== false)
                {
                    print "<div class=\"message\">Success!</div>";
                }
    $cnnxn = null;  
    }

（我知道日期部分是丑陋的。我的头直接工作已经太晚了。因为PDOException错误，我的头撞到了墙上。）

第93行是脚本执行查询的地方。

有什么想法吗？

Answer 1

仅供参考，这是一个错字

$query->bindParam('::question_text', $qtext);

应该是

$query->bindParam(':question_text', $qtext);

又一个＆＃39; SQLSTATE [HY093]：参数号无效：参数未定义＆＃39;
