Question

我已经找到了这个问题的答案，很多都接近我要找的东西，但还没有雪茄！

我有一个html表单，提交时转到php。 php做了一些基本的错误检查/验证。如果一切顺利，那么它会发送一封电子邮件。如果出现问题，我会通过以下方式发送警告弹出窗口：

echo "<script type='text/javascript'>alert('$message');</script>";

我的问题是，当用户点击弹出窗口中的“确定”后，我想将用户返回到表单，并将他们在表单中输入的所有数据保留在表单中，这样他们就不会有重新输入。我尝试过使用标题刷新，但这会让我看到一个空白表单。我尝试了类似于以下命令的各种混合：

echo "<input class="field" type="text" name="first_name" value = "<?php echo $_POST['first_name']; ?>"/>";

但它永远不适合我。另外，如果这是正确的事情，那么我不知道确切地将它放在代码中的位置（在头部命令之前，在头部之后但在javascript警报之前等）我也遇到了问题。线的语法和编码。

非常感谢能提供的任何帮助。

这是php文件。功能死亡是我试图让它为我工作的地方。
