Question

Stack Overflow不允许我发布2个以上的超链接，我需要3个，所以要查看我的查询，请点击以下链接：

我做的这个页面： [分页数据] [1]

显示人们在以下页面中输入的问题/评论： [联系艺术家] [2]

理论上说，一旦有人发表评论或提问，艺术家（杰克逊大卫，我正在为此页面制作）可以看到评论并在[回答问题或评论]中回复[3] ]页面。但是现在，艺术家必须将[Paginated Data] [1]部分的姓名和电子邮件地址复制并粘贴到[回答问题或评论] [3]表格。

我要做的是修改[Paginated Data] [1]页面以包括选择条目的功能，并让名称和电子邮件地址填写另一种形式的名称和电子邮件地址字段。通过这种方式，艺术家可以通过单击分页条目（例如，可能使用单选按钮）更轻松地回答客户的查询，并将客户的姓名和电子邮件地址自动填充到以下表单中： [回答问题或意见] [3]

以下是我从脚本网站获取的[Paginated Data] [1]页面的代码：

我想我需要在代码的以下行中添加某种形式：

$outputList .= '<h1>' . $Name . '</h1><h2>' . $email . '<br />' . $Comment . '</h2><hr />';

此外，如果我们可以自动选择条目并将姓名和电子邮件地址发布到，那将是一个奖励 [回答问题或意见] [3] 表单，而无需单击提交按钮。

如果将[Paginated Data] [1]的代码和[回答问题或评论] [3]的代码组合成一页更容易，我也可以这样做。

全部谢谢！

Answer 1

我终于通过血汗和眼泪得到了这个页面。我删除了一些混乱输入字段的isset编码。我还将进程从_POST更改为_GET。谢谢你的帮助！
