在$attachexists = $ispaid = FALSE下面添加
if (!empty($checktwo)) {
在最末尾的?>前添加
} else {
echo "<script>alert('写上你要提示的内容')</script>"
echo "<META HTTP-EQUIV=\"Refresh\" CONTENT=\"0URL=$PHP_SELF?checktwo=1&aid=$aid\">"
}

JavaScript一种直译式脚本语言，是一种动态类型、弱类型、基于原型的语言，内置支持类型。它的解释器被称为JavaScript引擎，为浏览器的一部分，广泛用于客户端的脚本语言，最早是在HTML（标准通用标记语言下的一个应用）网页上使用，用来给HTML网页增加动态功能。
为了取得技术优势，微软推出了JScript，CEnvi推出ScriptEase，与JavaScript同样可在浏览器上运行。为了统一规格，因为JavaScript兼容于ECMA标准，因此也称为ECMAScript。
javascript组成一个完整的JavaScript实现是由以下3个不同部分组成的：核心（ECMAScript）、文档对象模型（DocumentObjectModel，简称DOM）、浏览器对象模型（BrowserObjectModel，简称BOM）。
