Question

我正在创建一个储物柜注册Web应用程序。我有一个名为studentdata.php的页面，它显示从搜索查询中获取的学生信息（已完成）。

学生数据页面显示姓名，电子邮件，学生ID，课程/学习领域。旁边是一个具有另一种形式的div。该表单有一个下拉列表，显示该学生可用的储物柜。是什么让储物柜可用：它被分配给他们的程序并且studID为0（意味着没有学生分配给它）。

我想要的是什么：当我在下拉列表中选择其中一个储物柜时，它会动态显示该储物柜的组合以及该储物柜所在的部分（即1A）位于下方的两个输入字段中下拉列表 - 此信息存储在我最初检索更衣柜号码的表格中。

以下是代码：

<?php
    $url = $_SERVER['REQUEST_URI'];
    $studID = substr($url, strpos($url, "=") + 1);

$db_handle = mysql_connect("localhost", "root", "pickles") or die("Error connecting to database: ".mysql_error());
    /*
        localhost - it's location of the mysql server, usually localhost
        root - your username
        third is your password

        if connection fails it will stop loading the page and display an error
    */

    mysql_select_db("lockers",$db_handle) or die(mysql_error());
    /* tutorial_search is the name of database we've created */

$result = mysql_query("SELECT * FROM students WHERE studID = $studID"); 
    ?>

      <?php
  while($row = mysql_fetch_array($result)) 
  { 
  echo '<ol>';
   echo '<li>';
  echo '<label for=studid>Student ID</label>';
  echo '<input id=studid name=studid type=text value='.$row['studID'].'>';

      <select size="10" name="lockerSelect" multiple="yes" style="width:200px;">
      <?php

      while($row1 = mysql_fetch_array($result1)) 
  {
     echo '<option value=\"'.$row1['lockerScan'].'">'.$row1['lockerNo'].'</option>';
  }
