我正试图做一个mikrotik热点的singup表单，这个设备不允许在里面使用PHP，而且我需要将变量从设备传递到一个外部php页面挽救该负荷消费数据，并实现在热点的审判......两个HTML和PHP之间的交换变量
这个设备里面它主持了一个HTML页面下面的代码
<html>
<head><title>...</title></head>
<body>
$(if chap-id)
<noscript>
<center><b>JavaScript required. Enable JavaScript to continue.</b></center>
</noscript>
$(endif)
<center>If you are not redirected in a few seconds, click 'continue' below<br>
<form name="redirect" action="http://10.2.3.100/cadastro.html?mac=$(mac)" method="post">
<input type="hidden" name="mac" value="$(mac)">
<input type="hidden" name="ip" value="$(ip)">
<input type="hidden" name="username" value="$(username)">
<input type="hidden" name="link-login" value="$(link-login)">
<input type="hidden" name="link-orig" value="$(link-orig)">
<input type="hidden" name="error" value="$(error)">
<input type="hidden" name="chap-id" value="$(chap-id)">
<input type="hidden" name="chap-challenge" value="$(chap-challenge)">
<input type="hidden" name="link-login-only" value="$(link-login-only)">
<input type="hidden" name="link-orig-esc" value="$(link-orig-esc)">
<input type="hidden" name="mac-esc" value="$(mac-esc)">
<input type="submit" value="continue">
</form>
<script language="JavaScript">
<!--
document.redirect.submit();
//-->
</script></center>
</body>
</html>
我已经学会了在谷歌搜索，我可以送变量到另一个页面，通过在URL的末尾插入它，所以好的，我会发送变量$ MAC，我需要开始试用。
接收它的页面是一个HTML格式的页面，我无法接收这个页面中的变量，我需要接收这个变量发送到另一个页面，在PHP中最后一个将保存表单MySQL和后向Mikrotik发送与客户端的MAC链接，以允许它在互联网上浏览。

现在PHP页面

$query = "INSERT INTO `clientes` (`nome` , `email` )

mysql_query($query,$conexao);
echo "Seu cadastro foi realizado com sucesso!<br>Agradecemos a atenção.";

<meta http-equiv="refresh" content="60; url=<?php echo $linkloginonly; ?>?dst=<?php echo $linkorigesc; ?>&username=T-<?php echo $mac; ?>">
</body>
</html>
的想法是，从客户设备从的MikroTik与形式为客户singup接收MAC在其主持的HTML页面，该载荷经过HTML页面当客户点击发送过来将写信给mysql和发回的链接下方的MikroTik
<meta http-equiv="refresh" content="60; url=http://10.5.50.1?&username=T-<?php echo $mac; ?>">
我的整个问题交换HTML之间的变量HTML和PHP后页秒。
php会话可能吗？ – 2014-09-24 14:40:17
你可以使用JavaScript例如？然后你可以阅读你的网址中的参数.. – Matheno 2014-09-24 14:41:03
这看起来恐怖不安全。你确定**你的用户参数是[妥善转义]（http://bobby-tables.com/php）？ '$ _POST'数据**从不**直接进入查询。 'mysql_query'是一个过时的界面，不应该在新的应用程序中使用，并且会在将来的PHP版本中删除。像[PDO这样的现代化替代品并不难学]（http://net.tutsplus.com/tutorials/php/why-you-should-be-using-phps-pdo-for-database-access/）。如果您是PHP的新手，像[PHP The Right Way]（http://www.phptherightway.com/）这样的指南可以帮助解释最佳实践。 – tadman 2014-09-24 14:55:52
