【问题描述】：
我想在表格中显示数据库中的一条记录，每行都有复选框。该复选框将确定用户是否要删除该特定行（如果将被选中）。我能够显示数据库中的数据，但是当我按下删除按钮时没有任何反应。我不确定，但我认为错误在于我删除了部分代码，但我可能是错的。我不知道。无论如何，这是代码，我只是删除了一些行
<?php
$link = mysql_connect("localhost","root", "123");
if(!$link) {
die('Failed to connect to server: ' . mysql_error());
}
$db= mysql_select_db("abc");
if(!$db) {
die("Unable to select database");
}
$search = $_POST['search'];
$searchbox = $_POST['searchbox'];
$query = ("SELECT $search FROM table where $search = '$searchbox'");
$result=mysql_query($query);
if($result)
{
if(mysql_num_rows($result)<=0)
{
echo "<script type='text/javascript'>alert('The entry does not exist'); location.href = 'admin_home.php';</script>";
}
}
switch ($search)
{
case 'studentnumber':
$result = mysql_query("SELECT * FROM table WHERE $search = '$searchbox'");
if($result){
echo "<table class='hovertable'>
<tr>
<caption>Student Records</caption>
<th colspan='1'> Student Number</th>
<th colspan='8'> $searchbox</th>

while($row = mysql_fetch_array($result))
{
echo "<tr onmouseover=\"this.style.backgroundColor='#ffff66';\" onmouseout=\"this.style.backgroundColor='#d4e3e5';\">";
?>
