从分页数据库条目中提取数据并传递给表单

Question

Stack Overflow 不允许我发布超过 2 个超链接，我需要三个，所以要正确查看我的查询，请点击以下链接：

我制作的这个页面： [分页数据][1]

显示人们在以下页面中输入的问题/cmets： [联系艺术家][2]

理论上，一旦有人发表评论或问题，艺术家（杰克逊大卫，我为他制作此页面）可以看到评论并在[回复问题或评论][3 ] 页。但是现在，艺术家必须将姓名和电子邮件地址从 [分页数据][1] 部分复制并粘贴到 [回复问题或评论][3] 表单中。

我正在尝试修改 [分页数据][1] 页面，使其能够选择条目并让名称和电子邮件地址以另一种形式填充名称和电子邮件地址字段。这样，艺术家只需单击分页条目（例如可能使用单选按钮）并让客户的姓名和电子邮件地址自动填充到以下表格中，就可以更轻松地回答客户的查询： [回复问题或评论][3]

这是我从脚本站点获得的 [分页数据][1] 页面的代码：

我认为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，如果我们可以选择条目自动将姓名和电子邮件地址发布到 [回复问题或评论][3] 无需单击提交按钮即可提交表单。

如果将[分页数据][1]的代码和[回复问题或评论][3]的代码合并到一个页面中会更容易，我也可以这样做。

谢谢大家！

我终于在血汗和泪水中完成了这个页面。我删除了一些混淆输入字段的 isset 编码。我还将过程从 _POST 更改为 _GET。 感谢您的所有帮助！
