通过动态文本输入到PHP以写入文本文件(Pass dynamic text input to PHP

建立我的第一个网站，但无法弄清楚这最后一位。我RSVP形式有以下用户输入：1）一些客人在下拉选择菜单2）客人的姓名3）文本区域。用户选择的号码后，客人姓名文本框动态显示的姓名输入。一旦一切完成后，用户点击RSVP和PHP代码写入到文本文件。

问题：客户编号和文本区域写入罚款，但动态的客户名称框不获取传递到PHP。

我应该如何解决这个问题？被乱投医。任何帮助深表感谢。

你是不是张贴$_POST['guestnames'] ，但很多$_POST['guestnames_#'] 。

在你的HTML页面更改的guestnames投入名称：

input.name = "guestnames[]";

在你的PHP脚本，你现在可以访问$_POST['guestnames']

这将是一个数组，所以你必须做一些像

$guestnames = "";
foreach ($_POST['guestnames'] as $guest)
{
    $guestnames .= ", ".trim($guest); //trim whitespaces from beginning and end of string.
}

$guestnames = htmlentities(substr($guestnames, 2)); //strip the first comma and space and run through htmlentities.
