Question

我正在开发一个帮助票项目，除了这个方面，我已经有很大一部分工作了。我想将所有票证信息（从XML文件）显示到屏幕，但随后能够将带有新注释的注释附加到票证中。我打印所有的票证信息没有问题，它附加它是问题。一，因为我的$ _GET数组在提交后消失了，我丢失了故障单信息，其中两个我无法弄清楚如何在我的XML中为特定故障单的评论部分添加新评论。下面是代码。

Answer 1

在布劳哈利的帮助下，我能够弄清楚这个问题的其余部分。 SimpleXML不需要appendchild（）和addchild（）。我不得不使用

将新变量写入XML

$ticket->comments = $oldCom .  " " . $_POST['comments'];

然后我只需要使用

保存XML

file_put_contents("tickets.xml", $xml->asXML());

使用php SimpleXML附加到XML文件
