Question

问候大家

我有一个问题，在我通过PHPMailer发送电子邮件后，学生姓名和程序的值没有出现在电子邮件中。我正在使用PHP PDO，并且已经检查了学生姓名和程序是否在表单下。其他值在电子邮件中显示的很好，例如下面的图片：

我不确定是引号引起问题还是其他原因。下面是我的student-appointment-form.php文件的代码：

<?php

  require ('PHPMailer/PHPMailerAutoLoad.php');

  //Condition when the submit button is clicked
  if(isset($_POST["btnSubmit"])){
    try 
    {
      $appointment_date = date('Y-m-d',strtotime($_POST['appointment_date']));
      //$appointment_date = date("Y-m-d H:i:s");

      // Inserting the data into database
      $insert_query = "INSERT INTO appointment (appointment_type, appointment_date, appointment_time, student_id, lecturer_id, field, venue, remarks, appointment_status)
                        VALUES ('".$_POST["appointment_type"]."',

在您的表单中，您的var arr1=[3, 'a', 'a', 'a', 2, 3, 'a', 3, 'a', 2, 4, 9, 3, 'A']; var uniqueArray = arr1.filter(function(elem,i,rep){ console.log("index :"+i+" first indext of this value: "+rep.indexOf(elem)+" element :"+elem+ " is filterable :"+(i == rep.indexOf(elem)) ); return i == rep.indexOf(elem); }) console.log(uniqueArray);和student_name文件是programme，没有发布。考虑使用disabled输入值或将hidden更改为disable（不确定后者是否可以正常工作）。
