Question

我正在尝试创建一个表单来注册电子邮件订阅，这些订阅会发送到确切的目标（我们的邮件服务）。最初希望表单使用ajax jquery并在提交时将表单更改为成功消息或错误（取决于结果）。据悉，ajax表单提交不能在原始域SOURCE

之外完成

问题：

尝试让此表单提交并将数据附加到主页网址，以便在加载时显示不同的内容。有三种状态

如果GET为空，则加载表单
如果GET注册=错误
如果GET注册=成功

<?php
if (empty($_GET)) {
echo'
<form action="emailhost.net/subscribe.aspx" name="subscribeForm" method="post" class="forms" id="form">
<input type="hidden" name="thx" value="example.com/?signup=success" />
<input type="hidden" name="err" value="example.com/?signup=error" />
<input type="text" name="Full Name" placeholder="Name" />
<input type="text" name="Email Address" placeholder="Email Address" />
<input type="submit" />
</form>'
;}

if(isset($_GET["signup"]) && trim($_GET["signup"]) == "error"){
echo '
<p>There was an error. Please try again</p>
<form action="emailhost.net/subscribe.aspx" name="subscribeForm" method="post" class="forms" id="form">
<input type="hidden" name="thx" value="example.com/?signup=success" />
<input type="hidden" name="err" value="example.com/?signup=error" />
<input type="text" name="Full Name" placeholder="Name" />
<input type="text" name="Email Address" placeholder="Email Address" />
<input type="submit" />
</form>'
;}

if(isset($_GET["signup"]) && trim($_GET["signup"]) == 'success'){
echo'
<p>Thank you for signing up!</p>'
;}?>

隐藏的输入被发送到我们的电子邮件主机，并根据错误或成功，主机选择正确的值发回。

目前这不起作用。我从here

执行此操作的正确方法是将PHP用作您与客户端之间的一种代理（您从客户端收集表单数据，代表他们将其提交给第三方服务器，并检索结果）。

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $postdata = http_build_query(
                    $_POST, /* or wherever else you collected the data from */
                );
    $opts = [
      'http'=> [
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata,
      ]
    ];

    $context = stream_context_create($opts);

    $result = file_get_contents('http://emailhost.net/subscribe.aspx', false, $context);
    if ($result) {
        echo "<h1>Success!</h1>";
    } else {
        echo "<h1>ohnoes...</h1>";
    }
} else {
?>
<form action="myscript.php" name="subscribeForm" method="post" class="forms" id="form">
<input type="hidden" name="thx" value="example.com/?signup=success" />
<input type="hidden" name="err" value="example.com/?signup=error" />
<input type="text" name="Full Name" placeholder="Name" />
<input type="text" name="Email Address" placeholder="Email Address" />
<input type="submit" />
</form>
<?php
}

PHP表单提交然后检查网址以显示相应的内容
