信息提交后，表格就不會出現，信息也不會發送

Question

如果我單擊“通知”按鈕，則會發送郵件，但不會將其作為電子郵件發送，並且返回頁面也沒有表格，我已經回顯了該郵件，並且它在那里，但無法弄清楚

     <?php require_once("include/session.php");?>
    <?php require_once("include/dataconnect.php");?>
    <?php require_once("include/functions.php");?>
    <?php include("include/mheader.php");?>
   >
    <p>

        You can contact us so as to give you relevant numbers to speak to.Thank you.
    </p>

Answer 1

使用if ($message) {}有點棘手，如果您想知道$message包含一些文本，可以嘗試使用is_null或is_set

您也可以嘗試在表單中action之前action method

<form method='POST' action='notification.php' class='rl'>

Answer 2

我可以看到的一個問題在這里：

if ($message)
{
  ...
  $email = mysql_result($emails, 0);
}
$body = $message;
...

現在，即使$message計算為false並且沒有地址可發送，您仍在嘗試發送消息。

您需要將消息發送部分移至if ($message)部分。

編輯：您還將覆蓋$email變量：

$email= $results['email'];
//echo "$email";
//die();
if(mysql_num_rows($emails) == 0){
  exit("No email addresses found for user '{$_SESSION['username']}'");
}
$email = mysql_result($emails, 0); // get rid of this line

如果注釋的echo語句已經給出正確的結果，則可以擺脫其他重復的賦值。

除此之外，這可能是服務器問題，郵件正被發送到垃圾郵件等，但這與您的代碼無關。
