如何放置每个<；选择>&书信电报；选项>；组合框转换为PHP中的变量

我的PHP脚本的输出有点问题

此页面的目的是选择一个票证状态选项，例如：

• 打开票据（显示数据库中状态为“新建票据”或“正在审核”的票据）
• 新票证（显示数据库中状态为“新票证”的票证）
• 正在审核（显示数据库中状态为“正在审核”的票据）
• 已关闭的票证（显示数据库中状态为（已关闭票证）的票证）
  

用户选择状态后，代码必须显示具有所选状态的正确票据

所以我试着在每个选项后面放置一个数字变量，然后试着使它成为这样，当选择某个选项时，刷新页面，并用页面刷新发送该选项的变量-除了它不起作用，哈哈

我一直在用不同的想法进行头脑风暴，让它检查从组合框中选择状态获得的变量，但我还没有弄清楚这是多么令人沮丧

要点：

• 脚本必须在同一个页面上工作。为每个不同的状态创建一个新页面需要大量工作，而且效率不高
• PHP是主要的脚本语言，所以我更喜欢用PHP来回答

以下是当前代码：

<?PHP
session_start();
include('connection.php');

    </select><BR>"; 
    echo "Current listed support tickets: <BR><BR>";

        if ($int = '1')
        {
            $result1 = mysql_query("SELECT * FROM support WHERE status = 'New Ticket' OR 'Under Review'");
            while ($row1 = mysql_fetch_array($result1))

两个想法：

a） 您可以通过实现一些javascript来实现这一点，javascript在更改选择后切换每个票据的显示状态。

下面是一个未经测试（我没有您的数据库）的示例，说明AJAX将如何为您工作

如果您已经知道这一点，请原谅我，但是AJAX并不是什么新奇的东西——它是一个简单的方法，允许您从javascript调用另一个PHP文件

AJAX的工作原理是使用第二个PHP文件来完成下一步的工作，并将结果返回给javascript。流程如下：

在文件1中，javascript/jQuery获取用户选择的选项，并“调用”（AJAX）第二个PHP文件，传递用户的选择。实现这一点的代码位于该位下：

$('#type').change( function() { //grab the new value, send to File2 via AJAX });

File2（在本例中命名为“other_php_file.php”）（a）接收从File1发送的传递值，（b）执行数据库查找，（c）构建新的HTML，以及（d）将构造的代码（在一个名为$x的变量中）回显到File1

现在，这一点非常重要：File1在AJAX例程的
success:
函数中接收新代码。在这个SUCCESS函数中，它可以使用jQuery更新File1中的div。如果您希望用户按下其他按钮来执行另一个AJAX查找，那么下一个AJAX查找也必须在这个success函数中

无论如何，这应该回答您的直接问题：


文件1
